Impact - Typically each solar panel generates between 250 to 400 watts per hour, but it depends on many factors such as the size, weather, location and capacity. They are a great way of reducing greenhouse gases and carbon emissions, it's a natural resource and is sustainable. Although they may cost more than other green actions you could take, they can last for up to 30 years and are low maintenance. Depending on the factors previously mentioned, you can reduce your carbon by over one tonne per year.
Effort - Research is needed beforehand to find the best option for your home and the best deal. There are many businesses offering installations of solar panels and organisations offering grants - such as the Warmer Homes programme. Planning permission is often not needed to install the panels, but if you live in a listed building, conservation area or national park, restrictions may apply. They must be registered with your Distribution Network Operator (DNO) - the company responsible for bringing electricity to your home. Usually, your installer will register the device for you. Once you've picked which package you want to go for, a surveyor will come out to check if installation is possible for your home, and a plan will be put in place. It's important to note that if you don't own your home, you will need permission from your landlord.
Cost - An avergage solar panel system (4.2kWp) costs around £6,500. Depending on what system you go for, it can cost between £4,000 to £8,000. There are options to have these subsidised, such as the previously mentioned Warmer Homes scheme or the Low Carbon Across the South East (LoCASE) programme if you're looking to have these installed for your business. It's important to take the time to find the best option for you before going ahead with the installation.
