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.

How much can I save on my electricity bill with solar panels?

The amount you can save on your electricity bill with solar panels depends on factors such as:
  • Your current energy usage
  • The size of your solar system
  • Your local electricity rates
  • The amount of sunlight your panels receive
  • Available net metering policies
A qualified solar installer can assess your energy needs and provide an estimated savings calculation based on your individual circumstances.

What happens if my roof needs to be replaced after I install solar panels?

If your roof needs to be replaced after solar panel installation, a qualified solar installer can safely remove and reinstall the panels. It's advisable to have the roof inspected before installing solar panels to avoid needing a roof replacement soon after the solar installation.

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.
