What are solar AC modules? There are many different components that come together to form what we call a solar home system, but the most famous one is the solar panel itself. Also known as a solar module, this rectangular equipment has a grid-like pattern of solar cells that absorb power from the sun, creating an electric charge. In a conventional solar system, solar panels send direct current (DC) to an inverter that changes the power to alternating current (AC) to match the electricity in our homes. This renewable electricity is fed into the home’s circuit breaker panel to create a solar powered home.
