In a sunny state like North Carolina, a solar photovoltaic (PV) system can help you reduce your energy bills. Installing a PV system requires a significant investment, however, so careful planning is essential. Before you start shopping around for PV systems, consider these three factors:
Overall, the Fayetteville area receives enough sunlight to make solar energy a viable option, but the amount of electricity your system produces depends on exactly how much sun your home receives. Before you invest in a PV system, you’ll need a professional site analysis to make sure your location gets enough sunlight to meet your electricity needs.
To determine what size PV system you’ll need, first find out how many kilowatt-hours (kWh) of electricity you’ve consumed in the last 12 months. Then decide what percentage of your average electricity needs you want your system to meet. With that information, your solar energy system provider can determine the optimal system size for you.
Your roof size is another consideration. The typical home needs a PV system of between 3 and 6 kWh, which takes up 300-600 square feet of roof space. If you don’t have enough roof space, you may be able to use a pole- or ground-mounted system instead.
The average residential PV system can reduce energy costs by as much as 50 percent, National Renewable Energy Laboratory experts note. Even better, if you live in an area where heavier energy users pay higher rates, using less energy from your power company’s grid could mean paying less per kWh. How much you save depends on the output of your PV system.
Finally, remember to check with your city or county about local permits required to install a solar panel system.
