Are Solar Panels Worth It UK?
Many people in the UK are worried that installing solar panels on their roof isn’t worth it, as British weather is unpredictable and rarely sunny. It’s understandable that residents of places such as Glasgow, Cardiff or Preston, don’t believe that they get enough sun annually in order to power their homes through solar panels. Luckily, the experts at Direct Solar Care are here to turn that around! Read on to find out about how sunny the UK is, and just how much solar energy UK is needed to power solar panels!
How Much Solar Energy is There in the UK?
Britain is unfortunately infamous for its distinct lack of the sun, with the most common weather being overcast in the UK. As far as solar panels go, this is not the optimum weather to produce energy. It might even make you think that the amounts of solar energy UK make it not worth the hassle, however, you’d be wrong!
The solar panels still gather solar energy even in cloudy weather, however, they are not as effective as they would be on a sunny day. This is due to the solar panels receiving less light and therefore solar energy, which they then convert to electricity. To answer the question “are solar panels worth it UK?” you should also know that this is precisely why solar panels also don’t work at night, as they receive no solar energy, which means that days with more sunlight hours are more optimal. For example, solar panels will work better on a summers day, than a winter day, which gets darker quicker.
Are Solar Panels Worth It UK?
When it comes to installing solar panels in the UK, there are things you can do to increase the solar energy UK yield, which should help you to power your home sufficiently and efficiently. One of the best ways to increase light exposure for your solar panels is installing them facing a southern direction. This will maximise the amount of solar energy hitting the panels, as the sun moves from east to west each day. Another great way to increase energy production for your solar panels is making sure to minimise the solar panels being in the shade. All of those contribute to answering the question of “are solar panels worth it UK?”
Regularly keeping your solar panels clean is also very important, as dirty solar panels become less efficient with time. The dirt can also build up on solar panels, trapping the heat from escaping and therefore burning out the solar cells. This damages the solar panels permanently and reduces their efficiency even further. When it comes to cleaning solar panels, you should call us, as we are the best solar panel cleaning service! You can also read our blog for the best way of cleaning solar panels and increasing efficiency.
Why Are Solar Panels Good, and What Are the Best Solar Panels?
Back when solar panel technology was starting out, the components were bulky, heavy and costly to produce. With today’s modern advancements in technology, solar panels, in general, are lighter, more efficient, and less expensive to produce. Generally speaking, the most e
fficient solar panels are ones that can convert the most solar energy UK, into actual electricity, due to the photo-voltaic effect.
They also have an increased life span, meaning they produce power for longer, saving you money on replacing the panels. Investing in premium panels, such as the ones we offer for installation, also means that they will perform better than most other solar panels. This is great for areas such as Britain, which don’t get a lot of sun in the first place!
How Cloudy is Britain?
(Cities like Glasgow, are amongst the cloudiest in Europe. This makes us wonder, are solar panels worth it UK?)
Now that we know solar panels need solar energy and the sun in general, are they worth it UK? The answer to this question can vary depending on where you live. Don’t worry though as a simple formula exists, which we can use to work out if solar panels are viable for you!
Let’s start with ignoring the cloudy days, and focus on just the sunlight hours instead. Taking this into consideration, let’s use the city of Glasgow for our example. Statistically, the city has the least sunlight hours in Great Britain. Let’s say we have an average 2 square meter solar panel installed on our roof in Glasgow. The best solar panels have an efficiency of about 22% at converting solar energy into electricity.
The city of Glasgow gets about 1,203 sunlight hours annually, which works out to about 3.5 hours daily. With this figure in mind, we can take our panels’ square meter and multiply by a thousand. This gives us 2000, which we can then multiply again by our efficiency, to get the actual number (2000*0.22=440). After we get the actual sunlight figure, all we do is multiply it with our daily sunlight hours! This gives us a final figure of around 1,540 kW of electricity annually.
With the average household electricity consumption of around 3000 kW in great Britain, we have generated over half of that. We also did it in the cloudiest city in Britain, and from just one panel! Bare in mind we took only into account the sunlight hours and nothing else. This means that in reality, your panel is capable of outputting even more energy in a year! This is because it will also work on cloudy days, albeit with reduced efficiency.
So, Are Solar Panels Worth it UK, or Not?
Here at Direct Solar Care, our answer is a resounding yes! With a bit of math, it’s easy to see that investing in a solar array is worth it. Having at least two 2-metre square panels, you can easily cover your annual electricity usage. If you have the roof space, you can even invest in more panels! This will allow you to sell the energy to the national grid, and make a bit of tidy profit!
