How long does the whole process take?expand_more
The installation itself is usually one to three days, but permitting, utility interconnection approval, and inspection scheduling stretch the total to roughly two to four months in most cases. Anyone promising a switched-on system in two weeks isn't accounting for the utility.
What happens to the power I don't use?expand_more
Under net metering, excess generation credits your account, which matters here because Salem's summer surplus offsets the thin winter production. The details of how credits carry and eventually settle are set by your utility's tariff, so ask an installer to walk you through your specific one.
Should I lease or buy?expand_more
Buying, financed or cash, keeps the tax credit and the equity with you, and it's what most people ultimately prefer. Leases and power purchase agreements can look attractive monthly but complicate selling the house. Read any transfer clause carefully before signing.
Do I need to upgrade my roof or panel first?expand_more
Not necessarily, but both should be assessed before design. An aging composition roof under new panels and a full 100-amp electrical panel are the two most common reasons a solar project costs more than the first quote suggested.
Is this service free to use?expand_more
Yes. Describing your home and comparing bids from licensed local installers costs nothing, and nobody is obligated to buy anything.
