Main Service Panel

All homes have main service panels.  It is your home's electrical power distribution center.  If any of the circuits in your home are overloaded, this  is where you must go to reset the breaker and get things running again.  Circuit breakers are housed inside of service panels and are designed to prevent circuits from overloading the wires that transfer the electrical energy to the components requesting the energy.

There is a rule for determining if your service panel is sufficient for solar power.  It's a bit complicated, but you can read how much solar your home's electrical system can handle, without any major upgrades, over here

Solar electrical systems are wired into the main service panel, just like any other device.  The difference, however, is that the solar electrical system provides power, while most appliances consume energy.
