1. Roof-integrated solar tiles convert the sun’s energy into DC electricity and send it to an inverter near the main electrical service panel, likely in the garage.

2. The inverter converts the DC pulse into AC electricity that the load center distributes throughout the house as it does power from the utility grid. Depending on the offset, two inverters may be required to handle the electricity generated by the system.

3. Surplus electricity is sent to the local utility through the meter and main line (known as net metering) and counted as credits that are used as needed. Solar only pays off for homes designed and built to reduce their energy load up front.
