Choose a solar energy provider. Ask for references. Find out how many solar PV systems the provider has completed so you can gauge its experience. Request a free site evaluation to determine possible locations for your system, which could be the roof, garage or carport, a covered patio or on the ground.
Agree a monthly rate for your electricity, as well as the duration of the SPPA, which can be as long as 25 years -- the length of a standard system warranty. Compare the proposed monthly rate with what you currently pay to the utility company.
Wait up to two months for a completed solar PV system. The provider must file all necessary paperwork and register the project with your state's corresponding Solar Renewable Energy Certificate Registration Program. This registration, along with structural planning, filing for permits and managing inspections, adds to the time frame. The actual installation of the solar panels takes one to two days.
