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.

How long does it take to install solar panels?

The installation timeframe can vary, but a typical residential solar panel installation takes 1-3 days. Larger commercial installations can take longer. The actual time depends on factors such as:

• System size
• Roof complexity
• Weather conditions
• Permitting and inspections
• Installer's schedule

Your installer will be able to provide you with a more precise timeline for your specific project.

What is net metering, and how does it work?

Net metering is a billing mechanism that allows homeowners and businesses with solar panels to sell excess electricity generated by their system back to the utility grid. When your solar panels produce more electricity than you consume, the excess is sent to the grid, and your electric meter runs backward. You receive credits for this excess energy, which can offset your electricity bill. Net metering policies vary by location, but they generally make going solar more financially attractive by allowing you to earn credits for the electricity your system generates.

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.
