Q: What are photovoltaics or "PV"?
A: Photovoltaics can literally be translated as light-electricity. Photovoltaic materials and devices convert light energy to electricity.
Q: What are the components of a photovoltaic (PV) system?
A: A PV system is most often made up of:
- PV modules (groups of PV cells), also known as PV panels
- An inverter for a utility grid-connected system
- Mounting hardware or a framework
Q: What parts of my home can solar be used to power?
A: Solar can be used to power anything that draws power within your home, including lights, cooling systems, and appliances.
Q: What size system do I need?
A: The solar system you need will depend on your annual electricity usage and any future loads. Other factors that need to be considered in designing your solar system include the size of your roof and how much you are willing to invest. Contact a qualified contractor to determine what type of system would suit your needs.
Q: Does my roof need to face south for a solar system to work?
A: No question, southern exposure is best, but it’s not an absolute requirement. East and west-facing roofs still allow you to produce enough energy to lower your electricity bills, save money, and reduce your carbon footprint. An eligible contractor can help you determine if you have sufficient exposure for a solar system to be effective.
