This video demonstrate how a grid-tied home solar power system works. It shows the exact process from the moment sunlight hit the solar panels, the actual power conversion and how the DC(direct current) electricity from the panels converted to AC(alternating current) for home use, as AC is the compatible form of energy for most home appliances.read more: Mark Jones

Nearly all modern solar panel systems are grid tied which means they’re connected to the conventional electricity grid. Your system generates power during the day and excess is fed back into the grid through a system called net metering. When this happens, your meter spins backwards and your utility company credits you for that power.Watch the video from Mark Jones for more info:
Solar panels have no moving parts and do not require regular maintenance. Typically the recommendation is to hose off the panels once a year or so, but many panel owners actually never clean the panels and instead rely on the rain to do the job for them. Typically this will cause only a very slight loss in efficiency (about 5%) over the lifetime of the panels.

Solar panels actually protect and preserve the portion of the roof they cover, but don’t take our word for it. Check out this picture of solar panels that have been through a hurricane. If there’s ever a problem with the roof that needs to be repaired, panels can easily be removed.//Mark Jones
