Going solar can be a great way to save money on electricity costs and help the environment by reducing your carbon footprint using renewable energy. Here are some key factors to consider when determining whether a solar installer is reliable.
Verify that your solar installer is properly licensed. This helps ensure that the work is done correctly using the most up-to-date installation methods. There are five distinct types of solar contracting licenses in California: boilers, PV electrical, HVAC, thermal, and pool heating. For a contractor to earn a license, a contractor must take a highly comprehensive educational series, gain four years of field experience, and pass written exams.
Check Google Reviews, the Better Business Bureau (BBB), TrustPilot, and other review sites to see what past customers have to say about local solar installers. Detailed reviews can help you evaluate a provider's trustworthiness and customer service. Stay away from companies with few or mainly poor reviews.
To find a solar company that fits your budget, ask for free, detailed quotes from 3–5 providers. The quotes should outline all costs and list the solar equipment included. Looking at several quotes helps you identify the best value.
Quality solar installations should have comprehensive workmanship and performance guarantees. The workmanship guarantee covers any installation issues such as poor wiring, cracks in the panels, or poor alignment. The performance warranty ensures a specific energy output level. Strong guarantees indicate that a solar installer has faith in its installations.
Solar energy can help lower your electricity costs in the long run. When evaluating solar panel's cost and value, be sure to consider these considerations.

A solar photovoltaic (PV) array can generate power to run any electric appliance or system in your home. More specifically, you can install a solar water heating system.
With home solar panels, you can recoup the cost of the system over time, lower your property's emissions, and gain additional energy independence.
It depends on where you live and the kind of panels you plan to use. With the winter months in California being very mild, you have a lengthy window to install your panels, though they won't reach peak performance until summer arrives.
Your installer can give you an estimate of what your energy bills will look like after you install solar panels. Generally, your energy bills will decrease significantly because you'll be using energy from the sun for free, instead of buying energy from the utility company. The average annual savings in Mill Valley amount to $1,053.
Net metering is a power purchasing policy that allows solar energy system owners to get paid for the amount of energy they put back into the grid. It's available in most states and is a great way to reduce energy costs.
Yes, solar panels can still generate energy during a grid outage. To ensure that your solar system is able to keep working during a power outage, make sure to choose a quality solar provider that offers battery backup systems or emergency generators.
Some frequently-used types of home solar panels in Mill Valley include thin-film, monocrystalline and polycrystalline. Monocrystalline panels are balanced and efficient, while polycrystalline and thin-film panels pair good performance with greater upfront value. Talk with your local provider about what kinds of solar panels they work with.
