Mr Costanza and his crew did an excellent job on both the ground array and roof array and, after issues with PECO (that PECO acknowledged was definitely their fault), we went 'live' a year after the installation began. I give SunPower Builders an A+ rating - PECO...not so much.

Excellent design and installation of solar PV array and related electrical connections.

SunPower Builders designed and installed a solar array in the field in front of our home. It is low profile and easily accessible for cleaning when necessary. The technician that did the install were knowledgeable, courteous and efficient. The system is so well designed to our needs that the power created surpassed our needs within the first month of use and was fed directly back into the Electric Co. grid.

SunPower did a great job from design to install to ongoing support. I can even see how my system is doing right on my phone.

Sunpower designed, spec’d. costed, and performed all the work. Very thorough and friendly. Very satisfied with results.
