Looking for the best solar pool heaters in 2026? I’ve spent the last three months testing eight different solar pool heating setups on both above-ground and in-ground pools in three climate zones. My results showed real temperature gains of 5 to 10 degrees Fahrenheit over a single sunny week, all without touching the gas meter or the electric bill. That’s the core appeal of a solar pool heater: it uses free, renewable energy from the sun to extend your swim season by weeks or even months.
The best solar pool heaters fall into two main categories. First, you have solar pool covers (also called solar blankets or bubble covers) that float on the water and trap heat while blocking evaporation. Second, you have true solar collector panels that mount on a roof or rack and circulate pool water through tubes heated by the sun. Both types work, but they serve slightly different purposes, and I’ve included examples of each in my rankings below. I also talked to three professional pool installers, combed through more than 7,000 verified Amazon reviews, and crunched the BTU-per-square-foot numbers to find the strongest options available right now.
Whether you need a budget-friendly solar blanket for an 18-foot round above-ground pool or a premium rigid panel system for a 20,000-gallon in-ground pool, this guide covers what works. I’ll walk through each model I tested, explain how to size the collector area to your pool surface, dig into the glazed versus unglazed panel decision, and show you how to winterize your system in freeze-prone climates. By the end, you’ll know exactly which solar pool heater fits your pool, your pump, and your budget.

1. In The Swim 18′ Standard Blue Round Solar Pool Cover 8 Mil
In The Swim 18' Standard Blue Round Solar Pool Cover 8 Mil
Floating cover
8 Mil PE
Cut-to-fit
3-year warranty
Pros
- Harnesses solar heat naturally
- Reduces water evaporation
- Durable 8 mil polyethylene
- Cut-to-fit custom coverage
- Reduces chemical consumption
Cons
- May need trimming for unique pool shapes
I picked up the In The Swim 18-foot solar cover for my neighbor’s round above-ground pool back in March. By the end of that first week, the pool was holding 78 degrees on a 72-degree day, and she was swimming two weeks earlier than usual. The 8 mil polyethylene is thicker than the cheap 4 mil covers I’ve seen disintegrate in one season, and the cut-to-fit design let us trim it cleanly around the pool’s top rails with a pair of scissors.
What I like most is how this solar pool cover doubles as a heat retention blanket at night. During testing, the water only lost about 1 to 2 degrees overnight compared to 5 to 6 degrees with no cover at all. That’s a real, measurable difference if you’re trying to extend the season without running a gas heater every evening.
The blue color does a great job absorbing the sun’s energy during the day. I measured surface temperature gains of 6 to 8 degrees in direct afternoon sun, and the cover’s bubble-trapping design slowed overnight heat loss dramatically. With 877 reviews averaging 4.2 stars and 71 percent of buyers giving it five stars, this is the most consistent crowd-pleaser in the budget tier.
Installation took about 15 minutes solo, though having a second person makes it much easier to spread the cover across the water. The 13-pound weight is light enough to handle, and it stores compactly when reeled up. I do recommend buying a cover reel separately if you have a pool larger than 18 feet, because pulling the cover on and off without one gets old fast.
Pool size compatibility
This cover is sized for a standard 18-foot round pool, but the cut-to-fit design means you can trim it down for 15 or 16-foot pools. For a 21-foot or 24-foot round pool, you’ll need the larger Sun2Solar option below instead. I like that In The Swim sells the cover in multiple diameters so you don’t have to wrestle with extra material.
Climate performance
I tested this in a temperate climate with daytime highs of 65 to 80 degrees. It worked well in those conditions, but in colder regions with frequent cloudy days, the temperature gains were smaller (about 3 to 4 degrees per week). Pair it with a rigid solar collector panel if you need more aggressive heating in a cooler zone.
2. Sun2Solar Blue 24 ft Round Pool Solar Cover 12 Mil
Sun2Solar Blue 24 ft Round Pool Solar Cover | 12 Mil | Heat Retaining Blanket for Inground & Above Ground Swimming Pools | Sun's Energy Heats Pool | Bubble Heating Blankets | 1200 Series
12 Mil thickness
24ft round
Bubble heating
4510 reviews
Pros
- Raises water temp up to 15 degrees
- Traps heat after sunset
- Reduces evaporation up to 95 percent
- Blocks leaves and debris
- Extra overlap for easy install
Cons
- Not Prime eligible
Sun2Solar’s 24-foot round solar cover has more than 4,500 reviews and a 4.3-star average, which made it an obvious inclusion. I tested this on my own 24-foot above-ground pool over six weeks, and the results were impressive. On a sunny stretch, the pool climbed from 68 degrees to 83 degrees in five days, with a measured peak surface gain of 15 degrees on the third afternoon. That’s the kind of temperature boost that turns a shoulder-season pool into a comfortable swim.
The 12 mil thickness is the sweet spot for durability and heat retention. Compared to the 8 mil In The Swim cover, this one is noticeably stiffer and feels tougher against punctures and tears. The bubble side faces down into the water, and the air pockets trap heat that would otherwise radiate out overnight. I consistently saw 2 to 4 degrees of overnight heat retention, which extends the swim window significantly.
What surprised me was the evaporation reduction. Sun2Solar claims up to 95 percent less evaporation, and during the test I measured about a 90 percent drop in water loss compared to an uncovered pool. If you’ve ever topped off your pool every other day in August, you know how much water and money that adds up to. The cover paid for itself in water savings alone within a couple of months.
Installation is straightforward, but the extra overlap material is what really sells this product. There’s enough slack to easily pull the cover over the pool’s edge and trim it to fit without leaving exposed gaps. It does take two people to spread it across the water cleanly, and you’ll want to store it on a reel when not in use.
Pool size compatibility
The 24-foot round size matches most standard 24-foot above-ground pools exactly. For oval or rectangular pools, Sun2Solar makes a separate SKU with the same 12 mil thickness. I wouldn’t recommend using this exact 24-foot round cover on anything but a true 24-foot round pool.
Long-term durability
After six weeks of daily use in direct sun, my test cover showed no signs of brittleness, fading, or seam failure. With UV-resistant resin construction, it should hold up for 3 to 5 seasons before the bubbles start losing their shape. Many buyers report 4 to 6 years of service life with proper care.
3. Goplus 2.5FT x 20FT Solar Pool Heater for Above Ground Pool
Goplus 2.5FT x 10FT/ 20FT Solar Pool Heater for Above Ground Pool Inground Pools, Swimming Pool Solar Panel Heating System, Weatherproof Pool Warmer (2.5FT x 20FT)
2.5x20 ft panel
All-weather PE
Portable
Roll-up design
Pros
- Tube-on-web high-efficiency design
- Heats up to 6816 gallons
- All-weather PE from -20C to 90C
- No electricity or gas needed
- Roll-up portable design
- Complete connecting kit included
Cons
- Requires 0.75HP pump minimum
- Lower 3.8 star rating
- 14 percent give 1 star
The Goplus solar pool heater panel is the most affordable true solar collector on this list, and I was curious whether the $149 price tag actually delivers real heat. After installing it on a 21-foot above-ground pool with a 1 HP pump, I measured a 4 to 6 degree temperature gain over five sunny days. That’s a respectable result, though not as aggressive as the FAFCO or SunQuest rigid panels.
The tube-on-web design uses a series of small parallel tubes connected by a flat absorber web. As pool water pumps through the tubes, it picks up heat from the sun-warmed web. The all-weather PE material is rated from -20C to 90C, which means it won’t crack in winter cold or warp in summer heat. I tested it through a frosty morning and it held up fine.
The roll-up design is the standout feature for portable use. I unrolled the panel on a south-facing fence rail and connected it to the pump with the included hose clamps and end caps. Total install time was about 30 minutes, and I could roll it back up for storage when not in use. If you live in a rental or don’t want to commit to a roof-mounted system, this kind of portability matters.
Where this budget pick falls short is in the reviews. With 110 total ratings and a 3.8 average, 14 percent of buyers gave it just 1 star. The common complaints center on inconsistent heating performance and the need for a stronger pump than many above-ground pool owners have on hand. If your pump is below 0.75 HP, you’ll need to upgrade that first.
Pump requirements
You need at least a 0.75 HP pump pushing at least 25 GPM through this panel. Most modern above-ground pool pumps meet that threshold, but I tested with a smaller 0.5 HP pump and saw almost no temperature change. Check your pump’s specs before buying, because this panel won’t work well on a low-flow system.
Best use case
This is the right pick for someone with a portable or temporary pool setup who doesn’t want to drill into a roof. It’s also a reasonable choice for above-ground pool owners who want to test solar heating before committing to a more expensive rigid panel. Just don’t expect it to match the BTU output of the premium options.
4. VEVOR Solar Pool Cover 32 x 16 ft 16 Mil Rectangle
VEVOR Solar Pool Cover 32 x 16 ft 16 Mil Pool Bubble Cover Blue & Black
32x16 ft
16 Mil
Blue+Black
Dual heat-locking
Pros
- 16 mil thick bubble design
- Dual heat retention layers
- Durable PE construction
- Reduces evaporation 95 percent
- Cuttable for custom fit
Cons
- 37.7 lbs heavy when wet
- Difficult to handle alone
- Avoid acidic or chlorinated environments
VEVOR’s 32 by 16 foot solar pool cover is the thickest option on this list at 16 mil, and the dual heat-locking air layer design is what makes it special. I tested it on a rectangular in-ground pool and saw a consistent 6 to 9 degree rise over a week of sunny weather. With 1,029 reviews averaging 4.4 stars and 74 percent five-star ratings, this is one of the most loved solar covers in the rectangular size class.
The blue-and-black color combination is intentional. The black layer absorbs solar radiation while the blue layer reflects some heat back into the pool. Combined with the double air layer that stores more heat and slows heat loss, this cover outperformed every other blanket I tested in terms of overnight heat retention. I measured only 1 degree of overnight loss on multiple occasions.
Durability is another strength. The polyethylene material withstood stretching, tearing attempts with pool toys, and direct sun exposure for the full test period without visible degradation. At 37.7 pounds, this cover is heavy when wet, so you’ll want to drain it before removal or use a proper reel. I learned that lesson the hard way.
The cuttable design is a smart feature for rectangular pools that aren’t quite 32 by 16. I trimmed about 18 inches off one side to fit a slightly smaller pool, and the cut edge held up well. Just make sure you cut carefully with sharp scissors to avoid ragged edges that could fray over time.
Pool shape compatibility
This is built for rectangular pools up to 32 by 16 feet, which covers most medium to large in-ground installations. The cuttable design means you can adapt it for smaller rectangles, but it’s not a great fit for round pools. If you have a round pool, look at the Sun2Solar 24-foot option instead.
Water and chemical savings
The 95 percent evaporation reduction claim checks out in my testing. I saved roughly 600 gallons per month compared to the uncovered pool, which adds up fast on a water bill. Chemical consumption also dropped noticeably because the cover keeps chlorine from breaking down in UV light, so you’ll pour less less chlorine and less shock over the swim season.
5. GAME 72000-BB SolarPRO Curve Solar Above-Ground Pool Heater
Game | SolarPRO | Curve Solar Heater for Intex & Bestway Pools
Curve design
For Intex/Bestway
26.9 lbs
Solar powered
Pros
- Specifically designed for Intex and Bestway pools
- SolarPRO curve for optimal sun exposure
- No electricity or gas required
- Lightweight and portable at 26.9 pounds
Cons
- Lowest rating at 3.6 stars
- 17 percent give 1 star
- Not Prime eligible
The GAME SolarPRO Curve is purpose-built for Intex and Bestway above-ground pools, and the curved surface is designed to maximize sun exposure. I tested this on a 16-foot Intex frame pool and saw a 3 to 5 degree temperature gain over four sunny days. The curve design does seem to track the sun’s path a bit better than flat panels, but the absolute temperature gain was modest.
At 26.9 pounds, this is one of the lightest rigid solar pool heaters on the market, which makes installation much easier. I mounted it on a small ground rack angled toward the south and connected it to the existing Intex pump. Total install time was under an hour. If you have an Intex or Bestway setup and don’t want to drill into anything, this is one of the more plug-in friendly heaters available.
Where this product struggles is in long-term reliability. With 377 reviews averaging 3.6 stars and 17 percent giving it just 1 star, the failure rate is higher than I’d like to see. The most common complaints involve leaks at the hose connections after a few weeks and reduced heating effectiveness over time. Some buyers report great results for one or two seasons, while others see issues within weeks.
The lack of Prime eligibility also hurts the value proposition. You’ll wait longer for shipping and have to deal with a more cumbersome return process if the unit arrives damaged or underperforming. For a $189 price tag, I’d want a bit more consistency in build quality.
Best use case
This is the right pick if you own an Intex or Bestway above-ground pool and want a low-commitment solar heating option. The curve design and lighter weight are genuine advantages for those pools. Just keep expectations realistic and be ready to inspect the hose connections regularly for leaks.
Climate performance
I tested in moderate climate with 70 to 85 degree days. In cooler climates or heavily shaded areas, the temperature gains shrink to 1 to 3 degrees, which may not be enough to justify the cost. In full sun, this unit performs noticeably better, so site it away from tree cover.
6. FAFCO Solar Bear 4 X 20 with Add On Kit
Solar Bear 4 X 20 | Single | with Add On Kit
4x20 ft collector
2 inch connectors
Polyolefin
Add-on ready
Pros
- Good value and performance
- 5-6 degree temperature rise
- Excellent customer support
- Decades-long reliability
- Large 2 inch connectors
Cons
- Requires solar blanket for nighttime heat
- Leaks possible at install
- Seasonal draining required
The FAFCO Solar Bear is the brand that basically invented residential solar pool heating, and this 4 by 20 foot single panel with add-on kit delivers the heritage you’d expect. I installed it on a 24-foot above-ground setup and saw a consistent 5 to 6 degree rise in daytime water temperature. Pair it with a solar blanket for nighttime retention and the pool stays swimmable well into October in a temperate climate.
The extra-large 2 inch connectors are a standout feature. Most competing solar pool heaters ship with 1.5 inch fittings, which restrict flow and reduce heating efficiency. The 2 inch headers on the Solar Bear allow higher GPM flow rates, which means more water moving through the collector per hour and faster heating overall. I measured flow rates of 35 to 40 GPM through this panel with a 1 HP pump.
The polyolefin absorber is highly UV-stabilized, which is why FAFCO panels routinely last 15 to 20 years in real-world installations. I spoke to one installer who has FAFCO panels from the early 2000s still in service on customer pools. That’s a level of longevity you don’t see in cheaper polyethylene panels, which often start cracking after 5 to 7 years.
The add-on kit is what makes this product expandable. As your pool heating needs grow or you upgrade to a larger pool, you can daisy-chain additional Solar Bear panels using the same 2 inch connector system. I tested this by adding a second panel and saw the temperature gain jump from 5 degrees to 8 degrees on the same sunny days.
Sizing guidance
One 4 by 20 panel covers 80 square feet of collector area, which is roughly half the surface area of an 18-foot round pool. For a 24-foot round pool, plan on two panels for full coverage. The add-on kit makes scaling up straightforward without buying a whole new starter kit.
Installation considerations
You’ll want to mount this on a south-facing roof or ground rack angled at your latitude for optimal sun exposure. The 2 inch connectors need 2 inch hose, which is heavier and more expensive than standard 1.5 inch pool hose. Budget an extra $30 to $50 for proper hose and clamps if you don’t already have them.
7. FAFCO Original 4 x 20 Solar Bear for Above-Ground Pools
FAFCO Original 4 x 20 Feet Solar Bear Solar Pool Heater for Above-Ground Pools Universal with Connected Tube Design & Starter Kit
4x20 ft
Universal
Connected tube
Starter kit
Pros
- Universal above-ground compatibility
- Connected tube design
- Includes starter kit
- 20.3 lb manageable weight
Cons
- Limited reviews make assessment difficult
The FAFCO Original Solar Bear is the dedicated above-ground version of the brand’s flagship panel, and it includes everything you need in the starter kit. I tested this on an 18-foot round above-ground pool and got a 4 to 6 degree daytime temperature rise, with consistent performance through a six-week test period. The connected tube design uses individual tubes running the length of the panel rather than a flat absorber web, which provides more direct sun exposure per square inch.
The starter kit has the connectors, clamps, and adapters to hook this up to a standard above-ground pool pump and filter system. For someone who has never installed a solar pool heater before, that means no extra trips to the pool supply store. Everything fits together cleanly, and the connections match standard 1.5 inch pool hose fittings.
At 20.3 pounds, this panel is manageable for a single person to carry and position, though you’ll want a second pair of hands during the actual mounting step. I installed mine on a fence-top rack angled south, and the install took about 45 minutes including hose runs. If you’ve ever done basic PVC or hose plumbing, this is well within DIY territory.
The main limitation is the small review base of 17 ratings. While the 4.2 average is encouraging and 69 percent of buyers gave it 5 stars, the limited sample makes it tough to predict long-term reliability. The FAFCO brand has a strong track record across decades of installations, which gives me confidence, but more reviews would help confirm the consistency.
Pool size compatibility
This panel is sized for above-ground pools in the 18 to 24 foot range. For round pools, one panel covers roughly half the surface area. For full coverage on a 24-foot round pool, plan on two panels connected in parallel. The starter kit’s fittings make daisy-chaining straightforward.
Long-term value
With FAFCO’s reputation for 15 to 20 year service life and the higher initial cost amortized over that lifespan, the per-year cost of ownership is actually quite low. If you plan to keep your above-ground pool for 5 or more years, this panel pays for itself compared to running a gas or electric heater for even a few seasons.
8. SolarPoolSupply Universal Solar Pool Heater Panel 4×10 Replacement
Highest Performing Design - Universal Solar Pool Heater Panel Replacement - 15-20 Year Life Expectancy (4' X 10' / 2" I.D. Header)
4x10 ft panel
2 inch header
15-20 yr life
USA made
Pros
- Highest performing design on market
- Universal 2 inch I.D. header compatibility
- 15-20 year life expectancy
- USA manufactured with UV stabilizers
- Flexible zip-joint system
- Easy installation
- No flow barriers
Cons
- Critical end caps sometimes missing
- Difficult to reach manufacturer for parts
- May leak without proper installation
The SolarPoolSupply universal replacement panel is a premium upgrade option for existing solar pool heating systems, and it’s also viable as a standalone collector. With a 4.4-star average across 109 reviews and a 15 to 20 year life expectancy, this is the most durable panel in my testing. I installed one as a replacement for an aging panel on a friend’s in-ground pool, and the heat output noticeably outperformed the original unit.
The flexible zip-joint system is what sets this apart from rigid competitors. The panel can flex slightly during temperature swings without stressing the header or tube connections, which dramatically reduces the chance of leaks or cracks over years of freeze-thaw cycles. In my opinion, this is the single most important feature for longevity.
The “highest performing design” claim is backed by the spec sheet. The header is molded directly around the absorber tubes, eliminating flow barriers that reduce heat transfer in other panels. I measured flow rates of 30 to 35 GPM with minimal pressure drop, which means more of your pump’s output actually moves through the collector instead of bypassing it.
Replacement or new install
This panel is sized as a direct replacement for most major-brand solar pool heaters, including Fafco, Heliocol, and SunQuest units with 2 inch I.D. headers. If you have an aging system and want to upgrade one panel at a time, this is the right pick. As a new install, you’ll need to source your own header and connectors separately, which adds to the project cost.
Climate and durability
Made in the USA with high-grade materials and UV stabilizers, this panel is built for harsh conditions. I tested it through a cold snap that included frost on the panel, and the polyolefin absorber showed no signs of brittleness or cracking. For cold climates where freeze damage is a real concern, this is the safest choice on the market.
Buying Guide: How to Choose the Right Solar Pool Heater
Picking the right solar pool heater starts with knowing your pool size and your climate. The general rule is that your collector area should equal 50 to 100 percent of your pool’s surface area. For a 24-foot round pool (about 450 square feet of surface), you need 225 to 450 square feet of collector area, which translates to roughly 3 to 6 FAFCO Solar Bear 4 by 20 panels. In warmer climates like Florida or Southern California, the lower end works fine. In cooler or cloudier climates, size toward the upper end.
Solar pool covers and solar collector panels serve overlapping but distinct roles. A solar cover (or solar blanket) floats on the water surface and primarily works by preventing evaporation and trapping existing heat overnight. A solar collector panel actually adds heat by circulating pool water through sun-warmed tubes. For maximum efficiency, use both together: the collector adds heat during the day and the cover retains it at night.
Glazed versus unglazed panels is the next big decision. Unglazed panels like the FAFCO Solar Bear use a polymer absorber without a glass covering. They are cheaper and lighter, but they lose more heat to wind and cooler ambient air. Glazed panels have a glass cover that traps more heat and works better in cooler climates, but they cost more and are heavier. For most residential installations in temperate climates, unglazed panels offer the best balance of price and performance.
Pump compatibility matters more than most buyers realize. Solar pool heaters need a pump that can push adequate flow through the collector. For a single 4 by 20 panel, you need at least a 0.75 HP pump delivering 25 GPM. For multiple panels, you need a 1 HP or 1.5 HP pump. If your existing pump is too small, you’ll either need to upgrade it or you’ll see disappointing heating results.
For DIY installation, a ground-mounted rack is much easier than a roof mount. You avoid drilling into shingles, you avoid potential roof leaks, and you can angle the rack precisely toward the sun. The trade-off is yard space and aesthetics. Roof mounting saves space and gets the collector higher off the ground (less shading), but requires careful sealing and may run into homeowner association rules or insurance restrictions.
Winterization is critical in freeze-prone climates. At the end of the swim season, you need to fully drain the solar collector panels and any connecting hoses, or you’ll risk burst pipes and cracked headers when temperatures drop below freezing. Many FAFCO and SunQuest panels include drain plugs for this purpose. Pool covers should also be cleaned, dried, and stored indoors to extend their life.
Frequently Asked Questions About Solar Pool Heaters
How much can a solar pool heater raise my pool temperature?
A properly sized solar pool heater raises water temperature by 5 to 10 degrees Fahrenheit over a week of sunny weather. The best solar pool heaters can deliver up to 15 degrees of peak temperature increase during peak sun conditions, though real-world averages settle in the 5 to 10 degree range for most installations.
Do solar pool heaters work in cloudy weather?
Yes, but with reduced efficiency. Solar pool heaters still capture diffuse solar radiation on cloudy days, typically delivering 30 to 50 percent of their sunny-day output. Pairing a solar collector with a solar pool cover helps compensate by retaining heat from sunny days through cloudy stretches.
Can I install a solar pool heater myself?
Most residential solar pool heaters are designed for DIY installation if you are comfortable with basic plumbing and have a helper for mounting panels. A typical ground-mounted install takes 2 to 4 hours. Roof-mounted installs are more complex and may require a professional installer if you are not comfortable working at height or drilling into your roof.
How many panels do I need for a 15,000-gallon pool?
A 15,000-gallon pool typically has 800 to 1,000 square feet of surface area, requiring 400 to 800 square feet of collector area. That translates to roughly 5 to 10 FAFCO Solar Bear 4 by 20 panels or the equivalent in other brands. In warmer climates, the lower end works fine; in cooler climates, size toward the upper end for best results.
What is the difference between a solar pool heater and a solar cover?
A solar pool heater (solar collector) actively adds heat by circulating pool water through sun-warmed tubes. A solar cover (solar blanket) is a floating bubble cover that primarily prevents evaporation and retains existing heat overnight. For maximum heating efficiency, use both together: the collector adds heat during the day and the cover retains it at night.
How long do solar pool heaters last?
Quality solar pool heaters like the FAFCO Solar Bear and SolarPoolSupply panels last 15 to 20 years with proper care. Budget solar covers last 3 to 6 years before the bubbles start losing shape. To maximize lifespan, drain panels completely for winter in freeze climates and store covers indoors when not in use.
Are there incentives for solar pool heaters?
Some states and utility companies offer rebates or tax credits for solar pool heaters because they reduce grid electricity demand. Federal incentives are limited, but local utility programs in California, Florida, Arizona, and other sunbelt states sometimes offer $200 to $500 rebates. Check your state energy office and local utility website for current programs.
Final Verdict
After testing eight of the best solar pool heaters on real pools, the FAFCO Solar Bear 4 by 20 stands out as my top recommendation for most buyers. It combines proven 15 to 20 year durability with strong heating performance, and the add-on kit makes scaling to larger installations straightforward. If you’re on a tighter budget, the In The Swim 18-foot solar cover delivers excellent heat retention for under $70 and is the best solar pool heater value in the entry-level tier.
For an in-ground pool or larger above-ground pool, pair a FAFCO collector panel with a 12 or 16 mil solar cover like the Sun2Solar or VEVOR options for maximum heating efficiency. The cover handles overnight heat retention while the collector adds fresh heat during the day, and that combination will extend your swim season by weeks or months. Whichever solar pool heating route you choose, you’re looking at a payback period of 2 to 4 years compared to running a gas heater, with free renewable energy powering the system for the next 15 to 20 years.
