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 UK.

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.

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.

How do I know if my roof is suitable for solar panels?

A suitable roof for solar panels should have:
  • Adequate Sunlight: Unobstructed sunlight for a significant portion of the day.
  • Sufficient Space: Enough space to accommodate the desired number of panels.
  • Structural Integrity: A strong roof structure capable of supporting the weight of the panels.
  • Appropriate Orientation and Tilt: Ideally, the roof should face south (in the Northern Hemisphere) or north (in the Southern Hemisphere) with a tilt angle close to the latitude of your location. However, other orientations and tilts can still be effective.
A qualified solar installer can assess your roof during a site visit and determine its suitability for solar.

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.
