How it Works
The Grid-tied solar electric systems are the most efficient and the least expensive. The system consists of an inverter and photovoltaic solar modules. The modules convert the sun’s energy into electricity. They can be mounted to a roof or on the ground. The inverter converts direct current to alternating current which is used in your home. Grid-tied systems do not operate during a utility power outage because they must be connected to the utility to function.
Stand-alone PV systems, also called off-the-grid or off-grid, operate independently from the utility grid, providing all of the electricity needed in the home. Stand-alone systems are much more expensive than grid-tied systems. However, for homes located in remote areas without utility service, or where installing power lines would be extremely costly, a stand-alone system is a good option. Comfort Services can help you figure out which options works best for you in your greater Columbia SC home.
How does solar reduce your energy costs?
- The solar modules harness the sun’s energy to power the SunSource® Solar-Ready heat pump or air conditioner.
- When the heat pump or air conditioner isn’t running, the solar power can also operate other electrical devices in your home.
- With net-metering, any surplus power goes back to the grid possibly entitling homeowners like you to a credit.
- A communication module, which sends performance information for each solar module to a monitoring website, allows you to see the system status, energy production, and also shows the environmental benefits of using renewable energy for your home in Columbia SC.
