Solar panels are, perhaps surprisingly, quite a divisive topic. So what are the facts, and are solar panels worth investing in at the moment?What are solar panels?
Solar panels are devices that capture the energy from the sun and convert it into electricity.
How do they work?
They work by absorbing photons (tiny particles of light). When the photons hit the panels, their energy is transferred into them. That energy then ‘excites’ the electrons within the panel. These then flow through a circuit which produces electricity.
The type of electricity produced is direct current (DC). This electricity can then be stored and/or used to power devices. Because it uses particles of light, it doesn’t have to be vibrant sunshine for it to work.
How much do they cost?
The average domestic solar panel system costs around £7,000. This cost is based on 10 panels, which is enough to cover the average roof of a three-bedroom house.
What are the advantages?
There are a number of key advantages, notably the significant savings that can be made on electricity bills. Because solar is a low-carbon and renewable energy, a solar panel system can massively reduce your carbon footprint, potentially by as much as one tonne per year. Additionally, they have been shown to increase the value of a property by between 0.9% and 2%.
Solar panel installation in Yate
If you are considering having solar panels, there are several firms who specialise in solar panel installation Yate and the surrounding areas who can provide guidance and installation services.
How much money can solar panels save?
Savings are dependent on a number of factors, but the average solar panel installation on a three-bedroom house should shave around £400 off an annual energy bill. Additionally, there are several schemes where you can be paid for sending back excess electricity to the grid.
The average ‘break-even’ for a domestic solar panel installation is just over 14 years. And, because they usually last at least 25 years, there is actually a significant profit that can be made.
