Solar systems are often described in terms of the amount of power they are capable of producing in a given instant (measured in watts or kilowatts). The most important factor to take into account when comparing residential solar systems, however, is the amount of actual electricity the system is expected to generate during its lifetime (measured in kilowatt-hours). When compared to other brands, SunPower® high efficiency solar panels produce the most electricity in a wide range of conditions over the lifetime of the solar system.
With SunPower solar panels you can install more power in the same amount of space than with other panels—up to 50% more than conventional designs and up to four times more than thin-film solar. Since our residential solar systems require significantly less roof space, you can use fewer panels to produce the same amount of clean, renewable solar power. With fewer solar panels you can also maximise your roof space to choose the best, unobstructed location for electricity production.
