The Sunpower 250 watt solar panel is one of the highest efficiency PV modules available today. Powered by Sunpower Maxeon solar cell technology, the X20 series provides conversion efficiencies of up to 20.3%. The X20 250 watt has low voltage temperature coefficient and exceptional low-light performance attributes provide outstanding energy delivery per peak power watt.
Sunpower solar panels are only available for purchase with installation by authorized dealers. They are NOT sold separately.
Sunpower X20 250 Prices
We try to make it transparent and easy to compare solar prices, but you can not buy Sunpower panels separately. However, we can compare the real-world Sunpower 250 panel pricing information that is publicly available from the official reporting site of the California Solar Initiative (CSI) Program Administrators and the California Public Utilities Commission.
This presents actual costs and program data for Sunpower X20 250 watt modules and systems installed in California. These price includes modules, inverters, mounting, balance of systems (BOS) component and installation labor.
