Every home is different, so we will start by talking with you about your energy needs and project goals. We will review your historical electrical usage and evaluate your home based on the amount of sunlight it receives throughout the day and the amount of available roof space.

We will then provide an initial project estimate to show you how generating your own solar power can lower your electrical costs.
