SunPower v. SolarCity

Last week we installed a SunPower solar system on a home in Calabasas that previously had a SolarCity solar system. We really wanted to get a spot on comparison between the two manufactures rather than just take their word for each product. Here’s what we found. The SolarCity system is 5.390 kW and 397 sq feet. The SunPower system is 4.50 kW and 225 sq feet. The SunPower system although a little bit smaller took up 43% less space than the SolarCity system and produced more power on the same day of the year!! That’s all we needed to know to solidify that SunPower truly is a superior product than SolarCity. We’ll let you decide which system looks better on the roof.
