Having been in business over 25 years, SunPower is one of the world’s oldest and most established solar companies. As a transparent and publicly traded US company with market leading proprietary technology, SunPower is well positioned to maintain its market dominance well into the future.

Yes, it’s true that SunPower currently boasts the Guinness World Record for the most powerful solar cells. That says a lot about their commitment to quality and performance, but the full story lies beyond simply producing the most powerful solar panels available.

Having the most efficient solar panels allows you to put more power in a given area. What does this mean to you? It means having a larger system on your roof or having the same size system (wattage wise) in a sunnier area of your roof. Both choices result in more electricity generated on your rooftop.  The latter option allows you the benefit of installing more panels in the future to further reduce your bill or maybe to charge your electric vehicle (EV).

The SunPower advantage goes even further because efficiency is only part of the equation. Let’s forget for a moment that SunPower solar panels take up to a third less space to achieve a comparable kW size to conventional systems and focus on the benefits that reach beyond simple efficiency. Read on to learn why.

SunPower panels respond to a wider spectrum of light. This means that your system will start producing energy earlier in the morning and later in the day than any other solar panel. You will also produce more energy on cloudy days. The result is more kilowatt-hours (kWh) which is like money in the bank!

SunPower performs better under higher temperatures. The voltage of all solar panels drops as the temperature rises. SunPower panels are less affected by this phenomenon. As the temperature rises, the SunPower advantage increases.

SunPower maintains its efficiency during the initial break-in period. Solar panels experience a phenomenon when first exposed to light called LID “Light Induced Degradation” This result is an efficiency loss that is never regained. Due to the unique construction of the SunPower solar cell, this effect does not occur. The result to you is a more powerful return on your investment than conventional alternatives.

SunPower maintains its production year over year. The unique technology of the SunPower solar cell allows for more robust electrical connections. This means that over time your SunPower solar panels will experience less loss from micro-fracturing and degradation of the solder connections. This is why laboratory testing proves that SunPower has a lower annual power degradation factor than conventional solar panels.
