WHY EFFICIENCY MATTERS

More Power Means Fewer Panels

SunPower panels produce up to 50% more power than the competition, so you can use fewer panels to produce the same amount of power and maximize your roof space to choose the best, unobstructed location for electricity production.

Offset More of Your Bill

SunPower systems produce more electricity than other panels, which means less electricity purchased from the utility and more savings for you.

PANEL EFFICIENCY BY MANUFACTURER

Produce More Electricity

SunPower systems work harder for you day after day in a range of conditions. This means that your electric meter will spin backward faster and more often.

SUNPOWER® PANELS: Outperform competitors early in the morning, late

in the day and on cloudy days.Do a better job at absorbing

different kinds of light.

Not All Products are Created EqualSolar systems are often described in watts and kilowatts, however, the most important factor to consider is the amount of actual electricity it is expected to generate during its lifetime (kilowatt-hours). When compared to other brands, SunPower panels produce the most electricity in a range of conditions.

SUPERIOR REAL-WORLD PERFORMANCE

Perform better at high temperatures and maintain

performance when first exposed to light.

INDEPENDENT TESTS AROUND THE WORLD SHOW THAT SUNPOWER PRODUCES THE MOST ELECTRICITY (kWh)

Flexibility for the Future

Use less roof space to produce the energy you need today and gain the flexibility to expand later as your energy needs change (electric car, home addition, growing family).

SOL AR BOOSTS HOME SALE PRICES

U.S. Department of Energy’s Lawrence Berkeley National Laboratory study found that solar homes with an average system size of 3.1kW sold for approximately $17,000 or $5,500/kW more than non-solar homes.

Increased sale price was comparable to the average cost of system installation, and solar homeowners also enjoyed the benefit of lower electric bills.

System kW x $5,500 = $
