Frequently asked questions
Q: What is photovoltaic technology, or "PV"?
A: What do we mean by photovoltaics? The word itself helps to explain how photovoltaic (PV) or solar electric technologies work. First used in 1890, the word has two parts: photo, a stem derived from the Greek phos, which means light, and volt, a measurement unit named after inventor Alessandro Volta. So, photovoltaic can be translated roughly as "light-electricity", and that's just what photovoltaic devices do. V panels expose electrons to photons of light, increasing the energy state of the electrons then harvesting that surplus as electricity. Thus, we turn light energy into useable electricity.
Q: Can I use photovoltaics (PV) to power my home?
A: PV can be used to power your entire home's electrical system including lights, appliances, cooling systems, and pool heating. Furthermore, any unused energy goes directly back to the grid, feeding your neighbors consumption and turning your utility meter backward. The most common method of going solar for homeowners is to mount panels on the roof in a generally southward direction for maximum exposure. For an additional aesthetic appeal, panels and their racking systems can be colored to match your home, and can be mounted to your roof with a variety of methods to match your home's visual needs.
Q: Can I use photovoltaics (PV) to power my business?
A: Just as PV systems supply the electricity needs of a home, the same technology can be applied to commercial buildings. Today, PV can be seen everywhere, from solar panels on top of warehouses to solar panels surrounding agricultural fields. By using PV, businesses can erase their electricity spending. This means lower operating expenses and increased property value, not to mention the environmental benefits.
Q: Why should I purchase a PV system?
A: Solar is an excellent investment for three primary reasons. First, solar products help preserve the Earth's finite fossil-fuel resources and reduce air pollution. Second, solar systems greatly cut energy bills and fight utility rate increases of the future. Finally, a solar system on a home or business increases the value of the property. It is for these combined reasons that record numbers of Californians are going solar.
Q: How is a solar electric system designed, installed, and maintained?
A: Solar electric systems are complex appliances that require extensive design, permitting and licensed installation. The design process requires a licensed electrician to design the system according to the specific architectural and consumption needs of the building. Next, a licensed installation team is required to mount the panels and interconnect them with your building and the utility grid. Finally, occasional maintenance may be required over the 30+ year life of the system.
Thankfully, SFR Solar coordinates the entire process including the system design, permit application, interconnection agreement, material acquisition and installation. Furthermore, our installations are guaranteed for 10 years and our panels carry and 25 year warrantee.
