We have worked with Custom Solar for our 15kW system install w/battery during our Marshall Fire rebuild and they have been fantastic! Open communication during the planning, design, and install phase and they coordinated well with our builder and for permitting/inspections. Very easy to work with, project was completed and commissioned as expected, and now working with them on a second battery install! Thank you for the great work and fantastic experience!
