What Are The Benefits Of Domestic Rooftop Solar Panels?
Now that meteorological spring has arrived, the days are getting noticeably lighter and there has even been the rare sight of some sun in north London. There should be a lot more of this to come over the next few weeks.
That might get some householders thinking about the possibilities of solar power and, in particular, ask whether having solar panels installed on their rooftop could help save money. The final winter energy bills may encourage this thinking as well.
Can You Get Grants For Solar Energy?
You may be able to get a grant for installing solar panels. If so, the benefits will be significant.
- Your energy bill can fall by between 50 and 80 per cent
- You can get paid for surplus energy fed into the national grid
- They are VAT-free
- You are contributing towards a greener world
Why Is Solar Energy Controversial?
Of course, there are some naysayers out there who are not so keen on solar energy. Solar panels have been a hot topic of late, as, like windfarms, they have faced some criticism and questioning by sceptics and NIMBYs.
- Some have objected to the use of agricultural land for so-called ‘solar farms’
- Some question whether they can work in a cloudy country like Britain
- Some will ask what use they are in winter when the days are short and light levels are low
The first thing to note, of course, is that fitting them on house rooftops and other buildings has nothing to do with ‘solar farms’. Indeed, some people only support using more solar energy on the proviso that panels are mounted on buildings rather than in fields.
Secondly, solar power works from daylight, so there does not need to be direct sunlight on the panels. Clouds do not stop them. A simple example of this is a solar-powered device like an old pocket calculator, which was powered by daylight even when it was overcast.
Why Is Solar Power Still Useful In Winter?
The question of seasonal variations is a relevant one, because demand for electricity to provide heating and lighting is at its highest in winter and solar energy is most abundant in the long daylight hours of summer.
However, while that means solar power cannot meet all our energy needs, it is worth noting that even in the shortest days of the year in December, a panel in the UK produces, on average, around a fifth of the energy that it could generate in the long days of June.
This figure will vary depending on where you live in the UK, but it is worth noting that winter output will be greater here in London than in much of Britain, as the southerly latitude means days in the capital are not as short as they are further north.
Other factors can include what side of the house they are on (ideally south-facing) and how much shadow is cast by nearby buildings, trees and other objects.
We can help install panels on your roof this year. Some people might choose the spring and summer to fix the roof while the sun shines. You can have something fixed onto the roof that works in all daylight, whether you see any sunshine or not.
