Learning the basics of solar electric technology is the best way to confidently move forward with choosing a contractor and installing a PV system appropriate for your needs.
Photovoltaic (PV) systems convert light directly into electricity using semiconductor technology.
Making sure your home is energy efficient prior to installing solar is an essential first step. By reducing your overall energy use, you can reduce the size of the system you need, potentially saving thousands of dollars in up-front costs.
Estimating your system size
The average residential system is about 5 kW but there are several factors that impact the optimal system size for you, including your 12-month prior electricity usage and desired bill and energy offset as well as the space your home has available. If you do not have access to the last 12 months of energy bills, you can retrieve this information SCE.
Setting up your home with solar technology can reduce your energy bill and your carbon footprint. Before you choose a contractor and look at solar for your home it is always best practices to look at other efficiency measures first. You can save money in upfront costs by taking simple efficiency measures - like swapping old incandescent lighting for CFL or LED bulbs - to reduce your overall use.
Solar Permit Process
Please visit the Planning and Building Department to learn more about the permitting process and associated fees.
Solar chimneys are passive solar ventilation systems. Shafts connect the interior and exterior of the building. The functioning can be improved by glazing and using thermal mass materials. Learn more about solar.
