Frequently Asked Questions About Solar Installers

Will solar panels work during cloudy days or at night?

Solar panels still generate some electricity on cloudy days, although their output will be lower than on sunny days. They do not generate electricity at night. This is why battery storage can be a valuable addition to a solar energy system, as it allows you to store excess energy generated during the day for use at night or during periods of low sunlight.

What is the lifespan of solar panels?

Most solar panels have a lifespan of 25-30 years or more. Even after 25 years, panels will still produce electricity, but their efficiency may gradually decline over time. Reputable manufacturers offer warranties that cover defects in materials and workmanship for a significant portion of the panel's lifespan.

What happens to my solar panels during a power outage?

During a power outage, a grid-tied solar system without battery storage will automatically shut off for safety reasons. This is to prevent solar energy from backfeeding into the grid and posing a hazard to utility workers. If you have a battery storage system, your solar panels can continue to provide power to your home during an outage.

What kind of warranty should I expect for my solar panel system?

You should expect two main types of warranties for your solar panel system:

• Solar Panel Warranty: From the panel manufacturer, typically covering defects in materials and workmanship for 10-25 years. Some manufacturers offer performance guarantees, ensuring a certain level of energy output over time.
• Solar Installation Warranty: From the solar installer, covering the quality of the installation work for 1-10 years. This warranty protects you from leaks, faulty wiring, or other issues caused by improper installation.

Always review the warranty documents carefully before signing a contract.
