Frequently Asked Questions About Solar Installers

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

Planning permission requirements for solar panels vary depending on local regulations in UK. 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.

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.

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 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.
