It sounds appealing to have solar panels installed in your home. Solar panels provide free electricity whenever the sun shines. This can help you cut your energy costs and do your part for the environment.
Experts believe that reducing carbon emissions from heating and powering our homes is essential if we are to achieve our goal of becoming net zero by 2050.
Solar panels are becoming more appealing in a climate where energy costs are rising and people want to help the environment. What are the benefits and disadvantages of installing solar panels?
Consumers are increasingly conscious of the importance of using ‘green’ energy. Citizens Advice’s new research shows that nearly two-thirds are planning to improve their home’s energy efficiency in the next twelve months. NatWest however, found that 55% of homeowners plan to make green improvements to their home in the coming decade.
Wind and solar are the most cost-effective ways to generate electricity. They won’t run out, unlike more traditional forms of energy. With over one million solar panels installed on UK homes, it’s no surprise that this home improvement is very popular. These panels aren’t cheap but they can help you cut your electricity bills and reduce your carbon footprint over the long-term. You also get paid for any extra energy generated.
How do solar panels work
Photovoltaics, also known by the term solar electricity (PV), convert sunlight into electricity that can be used to power your home’s main electric supply. A solar PV panel is made up of layers of semi-conducting material such as silicon. If light shines on them, electricity flows. This allows you to generate your own electricity.
Your solar panels installed by solar panel companies UK will produce electricity that can be used to power appliances in your home. You will receive a payment for any excess electricity that isn’t used.
Thermal solar panels are another option if you are looking for solar panels. However, these panels can only be used to heat water.
How much do solar panels cost?
It all depends on the type of panel you choose. This will depend on how much electricity you use, how much roof space and how much you are willing to spend.
One solar panel costs between PS350 to PS500. A 4kWp system is the most popular and will typically cover 29 square metres of roof. It costs around PS6,000. According to the Energy Saving Trust (EST), an average domestic solar PV system costs about PS4,800, which includes VAT at 5%. It will usually take up about 15-20m2 of roof space, making it suitable to a typical terraced house.
What is the cost of solar panels to install?
The installation of solar panels is a large part of the cost. Therefore, the Energy Saving Trust (EST), recommends that you get quotes from at least three different installers.
If you have scaffolding for roof repairs, or are building a house from scratch, you can share some of the installation cost. The cost of panels and tiles will also be affected depending on whether they are building-integrated or if they sit on top. While panels on the roof are cheaper, tiles are more expensive.
Is it really possible to save money by installing solar panels?
The time it takes for solar panels to become profitable and how much you make from them will depend on their cost, the amount of electricity you can use, and how much you get paid for excess electricity.
According to Mike Childs (head of science at Friends of the Earth), solar panels placed on the roofs of buildings and homes won’t pay much in the first 20 years. He says that there are many environmental benefits depending on where you live, how much electricity you use. The average person produces 12.7 tonnes of carbon annually. However, solar panels can save around 1 ton of carbon each year.
Can my solar panels produce enough energy to make me a profit?
If your solar PV system produces more power than it needs, the excess will be returned to the national energy grid. The Smart Export Guarantee (SEG) was introduced in January 2020. It allows electricity suppliers to pay for every unit of power that you export to the grid. Although the previous feed-in tariff scheme was much more generous, it was closed to new customers at March 2019.
You can choose the best SEG tariff for electricity you sell back to the grid. This is independent of any contracts you may have with energy suppliers that power your home.
Variable or fixed SEG tariffs are possible. Fixed SEG tariffs will pay a fixed rate per kWh of electricity that is exported for the duration of the contract. Variable SEG tariffs will adjust the price according to market demand. Prices must not fall below zero.
Solar Energy UK offers a useful league table that shows which suppliers offer the most competitive rates. You can also contact Ofgem for information about its tariffs.
According to the Energy Saving Trust, a London household could save approximately PS295 per year on its energy bills by installing solar panels if someone is home. Additionally, a Smart Export Guarantee could help save another PS90 per year by selling excess energy.
