Frequently Asked Questions About Solar Installers

Have questions about going solar? Find answers to common inquiries about solar panel installation and connecting with reputable Solar Installers in USA.

What is the difference between grid-tied and off-grid solar systems?

Grid-tied solar systems are connected to the utility grid, allowing you to:
  • Draw electricity from the grid when your solar panels aren't producing enough power (e.g., at night)
  • Sell excess solar electricity back to the grid through net metering.
Off-grid solar systems are not connected to the grid and rely solely on solar panels and battery storage for electricity. They provide energy independence but require a larger upfront investment for batteries and a larger solar array.

How do solar panels work?

Solar panels work by converting sunlight into electricity using photovoltaic cells made of silicon. When sunlight hits a solar cell, it creates an electric current. Multiple cells are wired together to form a panel, and multiple panels can be combined to create a solar array.

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.

Do I need planning permission to install solar panels in USA?

Planning permission requirements for solar panels vary depending on local regulations in USA. In many cases, you may not need planning permission for a standard roof-mounted solar installation, especially if it doesn't significantly alter the appearance of your property. However, it's always best to check with your local planning authority or consult with a solar installer who is familiar with the regulations in your area.
