If you generate more electricity than you use (considering that your solar panel system is connected to the grid). You can generate electricity (photovoltaics) or heat (solar thermal).Solar energy can be used to produce electricity in areas without access to the energy grid, to distill water in regions with limited clean water supplies and to power satellites in space.If in doubt, you can always rely on specialised cleaning companies, which offer this service from around £25-£35.
Therefore, a few cloudy, rainy days can have a noticeable effect on the energy system.
You should also take into account that solar energy cannot be collected during the night.
Solar energy systems generally don’t require a lot of maintenance.
You only need to keep them relatively clean, so cleaning them a couple of times per year will do the job.
In most cases, it is smarter to just use solar energy during the day and take energy from the grid during the night (you can only do this if your system is connected to the grid).
Luckily your energy demand is usually higher during the day so you can meet most of it with solar energy.
While it has been widely criticised for being expensive or not very efficient, solar energy has now proved to be extremely beneficial - not only for the environment but also financially speaking.
Thanks to various solar panel grants as well as the ever-increasing higher demand, the technology has been improved considerably and has been complemented by solar battery storage systems, turning into a significantly more efficient source of clean energy.
Also, as there are no moving parts, there is no wear and tear.
The inverter is usually the only part that needs to be changed after 5-10 years because it is continuously working to convert solar energy into electricity and heat (solar PV vs. Apart from the inverter, the cables also need maintenance to ensure your solar power system runs at maximum efficiency.
