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 are the different types of solar panels?

The most common types of solar panels are:
  • Monocrystalline: Made from a single silicon crystal, known for high efficiency (typically 18-22%) and sleek black appearance.
  • Polycrystalline: Made from multiple silicon crystals, slightly less efficient (15-17%) but often more affordable than monocrystalline.
  • Thin-film: Made from thin layers of photovoltaic material, lower efficiency (8-12%) but can be flexible and lightweight.
The best type of panel for your project will depend on your budget, roof space, and desired energy output.

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.

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.

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.
