Going solar doesn’t mean disconnecting from the power grid. Since solar panels generate electricity only when the sun is shining, you still need to draw power from the utility at night, on cloudy days, and in some locales on winter days when the sun is low on the horizon. Your system will generate extra power when it is. .
Here’s what to keep in mind when choosing a company to put in your solar power system: 1. Get at least three bids—five is better for a. .
“Most people are surprised to learn that solar arrays won’t provide power during utility blackouts,” says Pearce. But it makes sense. They shut. .
The biggest difference between solar proposals is often the inverter technology. Inverters take the direct current (DC) produced by the PV panels and change it to alternating current (AC). [pdf]
