How Solar Power Works

November 29th, 2011 by ReVision Energy

Grid-tied photovoltaic systems – or PV, use solar panels to create electricity. When the sun strikes these panels, they generate direct-current, or DC power. This power then flows to an inverter, which converts the DC power into the alternating current, AC power used in your home.

If you’re running lights, computers, or other electric loads, your solar will power these loads first.

Any extra power your system makes you sell to the grid, generating a credit, which you can use whenever the sun is not out – at night or when it’s raining. At the end of the month, your credit bill will reflect either a positive credit from your solar electric generation or a bill reduced by as much solar electricity as you sold to the grid. Credits can be carried forward for a year.

With grid-tied solar electric, your home uses power just like it does now – no batteries or funny controllers. With a guaranteed environmental AND economic return on investment, solar power is one of the best investments you can make today.

    This is such a great system. It would be great if we could get everybody in the United States on solar power in the next 20 years.
