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.

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 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.

Do I need to replace my roof before installing solar panels?

It's not always necessary to replace your roof before installing solar panels. If your roof is in good condition and has several years of life left, solar panels can be installed on it. However, if your roof is nearing the end of its lifespan or shows signs of damage, it's advisable to replace it before the solar installation to avoid the cost and hassle of removing and reinstalling panels later. A solar installer can help assess your roof's condition and advise on whether a roof replacement is necessary.

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.
