The first step is to schedule a site visit for SOLAR Generation to determine the feasibility of a solar installation on your property. After the site visit, we provide a detailed proposal with photos, and in many cases, references to past projects. If you choose to move forward with our design proposal, we sign a contract and begin processing paperwork for the state grant, building permit, and utility interconnection. A typical residential solar installation takes about a week. In most cases, we need access to the mechanical room inside your house.
