Solar Optimum handled everything from permitting to final inspection. Our electricity bill went from $350 a month to nearly zero. The crew was professional and finished in two days.

We compared five companies and Solar Optimum offered the best value with QCells panels and Tesla Powerwall. Their design team optimized our roof layout to maximize production.
