Solar Installation FAQs

How do solar panels work?

Solar panels capture sunlight and convert it into electricity your home can use. Any excess electricity may be sent back to the utility grid through net metering, depending on your utility provider and current program rules.
Physical installation typically takes one to three days. The complete process, including consultation, design, permitting, inspections, and utility approvals, usually takes several weeks.
A properly installed solar system should not damage a structurally sound roof. Roof condition is evaluated before installation begins.
Yes. Solar panels continue producing electricity on cloudy days, although production levels are lower than on sunny days.
Yes. Solar panels generate electricity year-round. Production varies based on available sunlight, weather conditions, and seasonal daylight hours.
