FREQUENTLY ASK QUESTIONS
How does solar energy work?
1.
Solar panels convert sunlight into electricity through the photovoltaic (PV) effect. When sunlight hits the panels, it generates direct current (DC) electricity, which is then converted into usable alternating current (AC) electricity by inverters.
What are the main components of a solar power system?
2.
A solar power system typically includes solar panels, inverters, mounting structures, and a monitoring system. Battery storage may also be part of the system for off-grid or backup power.
What are the benefits of installing solar panels in California?
3.
Installing solar panels in California can reduce electricity bills, decrease dependence on fossil fuels, lower carbon footprint, and potentially qualify homeowners for financial incentives and rebates.
Are there any financial incentives for installing solar panels in California?
4.
Yes, California offers several incentives, including the California Solar Initiative (CSI), federal Investment Tax Credit (ITC), net energy metering (NEM) programs, and property tax exemptions.
How much do solar panels cost in California?
5.
The cost of solar panels varies based on factors such as system size, quality of equipment, and installation costs. However, prices have generally decreased over the years, and various financing options are available to make solar more affordable.
How much sunlight does California receive, and is it enough for solar panels to be effective?
6.
California receives abundant sunlight, making it an ideal location for solar energy. Most regions in the state receive enough sunlight to make solar panels highly effective.
Can I go off-grid with solar panels in California?
7.
Yes, it's possible to go off-grid with solar panels by combining them with energy storage systems like batteries. However, going off-grid may require a larger initial investment and careful consideration of energy needs.
What is net metering, and how does it work in California?
8.
Net metering is a billing arrangement where excess electricity generated by a solar system is fed back into the grid, and the customer receives a credit for it. This allows users to offset their electricity costs. In California, this helps offset the cost of electricity drawn from the grid during periods when solar production is insufficient.
Are there any restrictions or regulations for installing solar panels in California?
9.
While there are generally no statewide restrictions, homeowners should check local regulations, and homeowners' association rules, and obtain necessary permits before installing solar panels.
How long do solar panels last, and what is their warranty?
10.
Solar panels typically have a lifespan of 25 to 30 years or more. Warranties often cover 20 to 25 years, with guaranteed performance levels during that period.
Can I install solar panels on a shaded roof?
11.
While solar panels perform best in direct sunlight, some systems can still be effective with partial shading. Advanced technologies, such as microinverters and power optimizers, can mitigate the impact of shading.
What is the environmental impact of solar energy?
12.
Solar energy is considered a clean and renewable energy source. While the manufacturing process has some environmental impact, the long-term benefits in terms of reduced greenhouse gas emissions outweigh these concerns.
Can solar panels work during cloudy days?
13.
Yes, solar panels can still generate electricity on cloudy days, although their efficiency is reduced. They don't require direct sunlight; they can produce power from diffuse sunlight.
Can I use solar power during a power outage?
14.
If you have a grid-tied system without battery storage, it typically shuts down during a power outage for safety reasons. However, systems with battery storage can provide power during outages.
