How do solar panels work?

Solar panels operate by harnessing the power of the sun through photovoltaic (PV) cells, which are key components in converting sunlight into electricity. These PV cells are composed of layers of semiconductor materials, commonly silicon, which have been chemically treated to establish an electric field. This electric field is crucial for the movement of electrons within the semiconductor.

When sunlight strikes a solar panel, the energy from the sunlight is absorbed by the semiconductor material. This absorption excites the electrons, causing them to move freely. The movement of these electrons generates an electric current. This current is then directed through conductive wires, which channel the electricity for immediate use or store it in batteries for later use.

Solar panels provide a sustainable and renewable source of energy, making them an excellent choice for reducing energy costs and minimizing environmental impact for homes, businesses, and other buildings.

The benefits of solar panels?

Reduce your electricity bills

Solar panels harness sunlight to generate free, low-carbon electricity, significantly lowering your bills. By producing your own energy, you rely less on suppliers and avoid price hikes. This free energy can power your home, charge your electric car, and even provide hot water.

Environmentally friendly

Solar energy reduces reliance on fossil fuels, cutting greenhouse gas emissions and combating climate change. Choosing solar power is a key step toward a sustainable future and lowering your carbon footprint.

Quick and easy installation

Solar panels come in various types and can be quickly installed on your roof or integrated within the roofline. They require minimal maintenance and are often permitted even in conservation areas.

Maximise your solar power potential

Adding a battery to your solar PV system increases its effectiveness by nearly 40%, allowing you to store and use more solar energy when you need it most.

Earn money by generating & exporting electricity

The Smart Export Guarantee (SEG) pays you for the renewable and low-carbon electricity you supply to the grid, allowing you to earn money while supporting clean energy.

Take advantage of 0% VAT

Solar panel installations now benefit from 0% VAT, making investing in renewable energy more affordable and providing a great opportunity to go solar.

FAQs

  • Yes, solar panels can be installed on a flat roof. Special mounting systems are used to position the panels at the optimal angle to capture sunlight, ensuring maximum efficiency and energy production.

  • Absolutely, you can install solar panels in your garden. Ground-mounted solar panels are a great option if your roof isn't suitable or if you have ample space in your garden. They offer flexibility in placement and can be adjusted for optimal sun exposure.

  • Yes, solar panels work all year round. While their efficiency is higher in sunny conditions, they can still generate electricity on cloudy days and during winter months. Advances in solar technology ensure that panels continue to produce energy even in less-than-ideal weather conditions.

  • Yes, you can add a battery storage system to your solar panel setup. This is a fantastic way to maximize the benefits of your solar panels By storing excess energy generated by your solar panels, you can use it later when needed, enhancing your energy efficiency and independence.

  • To determine if you have enough space for solar panels, consider the size and layout of your roof or the available ground area. Solar panels require a clear, unobstructed surface to capture sunlight effectively. Generally, a typical residential solar panel system requires about 200 to 400 square feet of roof space. Additionally, ground-mounted systems can be an alternative if your roof space is limited.

  • Ideally, solar panels should face south in the Northern Hemisphere to capture the most sunlight throughout the day. However, east or west-facing roofs can still work effectively, though with slightly reduced efficiency. Your roofs orientation can be assessed for optimal energy production.

  • For solar panels to be effective, your roof should receive ample sunlight without significant shading from trees, buildings, or other obstructions. Solar panels perform best in direct sunlight, so it's essential to evaluate any potential shading issues. A solar assessment can help determine if your roof gets sufficient sunlight throughout the year.

  • In many cases, solar panel installations on residential properties do not require planning permission, especially if the panels are installed flush with the roof. However, if you live in a conservation area, a listed building, or plan to install a ground-mounted system, you might need to seek permission. It's always best to check with your local planning authority to ensure compliance with any regulations.
