Adopting solar energy in the UK has numerous financial and environmental benefits. If you’re contemplating installing solar panels at your home, here are some of the most frequently asked questions to help guide your decision.

Frequently-asked-solar-questions1. How do solar panels work?


Solar panels are made up of photovoltaic (PV) cells, which convert sunlight into electricity. This process is known as the photovoltaic effect. The electricity generated can either be used directly in your home, stored in battery systems for later use, or exported back to the national grid. Learn more about how solar panels work.

2. What are the benefits of installing solar panels?


The primary advantage of solar panels is the reduction in electricity bills since you’ll be generating your power. Solar energy is a renewable resource, which means it’s also better for the environment as it reduces reliance on fossil fuels and cuts down on greenhouse gas emissions. Additionally, any surplus energy you produce can be sold back to the grid, earning you credits or additional income through schemes like the Smart Export Guarantee (SEG). Read about the benefits of solar energy.

3. How much does it cost to install solar panels?


The cost of installing solar panels can vary widely based on the size of the system, the quality of the panels, and the complexity of your installation. Generally, the price for an average residential solar panel system ranges from £4,000 to £8,000 in the UK. It’s advisable to obtain multiple quotes to ensure competitive pricing and quality service. Get an estimate for solar panel installation.

4. Can I get any government grants or incentives?


While direct government grants for solar panel installation are less common today, the Smart Export Guarantee (SEG) provides a financial incentive for home solar energy generation. Under SEG, energy suppliers pay you for the surplus electricity you export back to the grid, making solar installations more economically attractive. Find out more about the Smart Export Guarantee.

5. How long do solar panels last?


Solar panels are designed to be durable and long-lasting. Most solar panels come with a warranty of 25 years, but they can continue to generate electricity well beyond that time frame, although their efficiency may decrease slightly as they age. Understand solar panel longevity.

6. Do solar panels require a lot of maintenance?


Solar panels require very little maintenance. Keeping them clean and free from obstructions like leaves or snow is generally all that’s needed to ensure they operate efficiently. Many installers offer maintenance services and can monitor your system’s performance remotely. Learn about maintaining solar panels.

7. Do solar panels work on cloudy days?


Yes, solar panels can still generate electricity on cloudy days, though their output will be reduced compared to sunny days. The UK’s climate is suitable for solar energy generation as panels can produce electricity even in diffuse light. Read more about solar energy in cloudy conditions.

8. What should I consider before installing solar panels?


Consider the orientation and tilt of your roof, potential shading from nearby trees or buildings, and the overall condition of your roof. South-facing roofs without shade receive the most sunlight and are ideal for solar panels. It’s essential to have a professional assess your property to ensure it is suitable for a solar installation. Check your home’s suitability for solar panels.

What our customers say

I was thinking about getting solar for my home and stumbled upon The site's super easy to get, breaking down all the solar jargon. After reading up for a bit, I filled out their quote form. The next day, I got calls and emails from three solar companies in South Wales. Chatted with all of them, got quotes, and went ahead with one. The whole experience was smooth, and all the companies seemed top-notch. Big thumbs up!

Running a business, those rising energy bills were starting to pinch. So, we thought, 'Why not try solar?' A quick online search led us to Solar Planet. Filling out their quote form was a breeze, and guess what! The very next day, three solar experts from Bristol gave us a shout. They were all super helpful and knew their stuff. Picking one was tough since they all had great offers. And a big relief! They all had this MCS accreditation – a real peace of mind with all those dodgy stories you hear these days.

It couldn't have been easier! Initially, we were scratching our heads trying to find a trustworthy company. Then, thanks to a quick Google search by my husband, we landed on Solar Planet. He filled out their quote form, and the next day, three different solar installers rang us up. We've been over the moon with both the installation and the ongoing support. They guided us through the whole process from installation to helping us find the best energy provider for solar power.
