SOLAR PANELS

Let's get into the details 

How does solar power work for homes?

Solar power for homes involves installing photovoltaic (PV) panels on the roof or in the yard. These panels capture sunlight and convert it into electricity through the photovoltaic effect. The electricity generated can be used to power your home's appliances and lighting.

What are the benefits of installing solar panels on my home?

Installing solar panels can provide numerous benefits. You can save money on electricity bills by generating your own renewable energy. Solar power helps reduce carbon emissions, making your home more environmentally friendly. Additionally, you can earn money through feed-in tariffs or the Smart Export Guarantee (SEG) by selling excess electricity back to the grid.

How much does a home solar system cost?

The cost of a home solar system depends on various factors, such as the size of the system, the quality of the panels, and the complexity of the installation. On average, a typical residential solar system in the UK can cost between £4,000 to £8,000 per kilowatt (kW) of installed capacity.

What is the return on investment (ROI) for a residential solar installation?

The ROI for a residential solar installation can vary depending on factors such as the system cost, available sunlight, and electricity usage. In the UK, the average payback period for a solar system is around 8 to 12 years, with a potential ROI of 5-10% per year over the system's lifespan.

Can I generate enough electricity to power my entire home with solar panels?

It is possible to generate enough electricity to power your entire home with solar panels. However, the system size and available roof space will determine the amount of electricity generated. In some cases, you may still need to rely on the grid for additional power during periods of high demand or low sunlight.

What happens to the excess electricity generated by my solar panels?

In the UK, if you generate excess electricity, you can sell it back to the grid through the Smart Export Guarantee (SEG). Energy suppliers offer tariffs for the surplus energy you export, allowing you to earn credits or receive payment for the electricity you produce but don't use.

How long do solar panels last, and what is their warranty?

Most solar panels are designed to last 25 to 30 years or more. However, their performance may degrade slightly over time. Solar panel warranties typically cover the panels for 20 to 25 years, guaranteeing a certain level of performance during that period.

Are there any government incentives or tax credits available for installing solar panels?

Yes, the UK government offers incentives for installing solar panels. The Smart Export Guarantee (SEG) allows you to earn money by selling excess electricity to the grid. Additionally, the Renewable Heat Incentive (RHI) offers financial incentives for renewable heating systems, including solar thermal panels.

Do I need to have a south-facing roof for solar panels to work efficiently?

While south-facing roofs generally receive the most sunlight in the UK, solar panels can still work efficiently on east or west-facing roofs. Even roofs facing north can benefit from solar panels, although the electricity generation may be lower compared to south-facing installations.

Can I still use electricity from the grid when I have solar panels installed?

Yes, you can still use electricity from the grid when you have solar panels installed. Solar panels produce electricity during the day, but at night or during periods of low sunlight, you can rely on electricity from the grid. This ensures a continuous power supply for your home.
