Solar power works by converting sunlight into electricity through the photovoltaic (PV) effect.
The PV effect is when photons from the sun’s rays knock electrons from their atomic orbit and channel them into an electrical current.
Using PV solar panels, sunlight can be used to power everything from calculators to homes to space stations.
In a house with solar panels, inverters and batteries, the process is as follows:
When sunlight hits a solar panel on the roof, it creates an electric charge through the PV effect.
The solar panel feeds this electric charge into inverters, which change it from direct current (DC) to alternating current (AC) electricity.
The AC electricity runs through your electrical panel and is distributed throughout your home, just like grid energy.
Excess solar energy is stored in batteries or pushed onto the grid to power local systems.
Through net metering, solar owners get credit for the excess energy they put on the grid to offset the grid energy they pull off the grid when their panels aren’t producing.
With battery storage, solar owners can store excess production to power their homes at night.
Choosing a solar installer is an important decision that can affect the performance and durability of your solar system. Here are some tips on how to choose a solar installer:
Get in the right mindset. Solar is a long-term investment that will save you money and reduce your environmental impact. Don’t rush into a decision based on price or pressure from salespeople. Do your research and compare multiple quotes from different installers.
Check the credentials and reputation of the installer. Look for industry-standard certifications which indicates a high level of training and expertise.
Make sure the installer is licensed and insured to install residential solar projects in your area. Ask for references and read online reviews from previous customers. Avoid installers with a history of complaints or claims.
Prefer local companies that have been in business for a long time. Local installers are more likely to have experience with your climate, roof type, and utility regulations. They may also offer better customer service and support after installation. Choose an installer that has at least three years of experience and has installed many solar systems similar to yours.
Ask about the quality and warranty of the solar equipment. Find out what brands and models of solar panels, inverters, and batteries the installer uses and why.
Compare the efficiency, durability, and aesthetics of different options. Ask about the manufacturer warranties for each component and the workmanship warranty from the installer. Make sure you understand what is covered and for how long in case of any issues or defects.
Understand the contract and financing options. Read the contract carefully and make sure it includes all the details of the installation, such as the system size, cost, timeline, payment terms, performance guarantee, maintenance plan, and net metering agreement.
Ask questions if anything is unclear or missing. Compare different financing options such as cash, loan, lease, or power purchase agreement (PPA) and choose the one that suits your budget and goals. Be wary of any hidden fees or penalties.
Communicate with the installer throughout the process. A good installer should be transparent and responsive to your questions and concerns. They should keep you updated on the progress of the installation and any changes or delays. They should also provide you with clear instructions on how to use and monitor your solar system after installation.
Above all don’t be pressured and don’t rush.
