Solar panels are a great way to generate your own electricity and do your bit for the environment. But before you get and install them, you will need to make sure you get the right system.
Domestic solar panel installations include 1kW, 2kW, 3kW and 4kW systems. The 4kW solar system is the installation that will generate the most electricity and earn you the largest amount of money. But is it the right solar panel system for your roof?
To help you decide, we’ve made a list of the 4kW system’s cons and advantages.
Generates free electricity
A top benefit of solar panels is that they generate free electricity. Sunlight is free, so the electricity that you will generate from it is also free. The more solar panels you have, the more free electricity you can generate. So if you want to generate as much free power as possible, it’s a good plan to install a 4kW system.
Reduces your carbon emissions
Another advantage to solar panels is that using them can help you to reduce your carbon emissions. The production of most mains electricity releases carbon dioxide into the atmosphere. But the generation of solar power doesn’t.
So by using solar power instead of electricity from the grid, you’re cutting your carbon emissions.
Lowers your electricity bill
Producing power through solar panels can decrease your electricity bill also. It is because you utilise the free solar energy you generate rather than electricity bought from your electricity provider. So developing a solar power system decreases how much electricity you will need to buy and slashes your electricity costs.
Solar panels offer the chance to earn money also. The UK government’s Feed-in Tariff scheme will pay you for the electricity that your solar panels generate, even if you use it.
You can also generate income by selling the energy you generate but don’t use back to the mains. You’ll get paid a rate per unit for this too.
As 4kW systems generate more electricity than 1kW, 2kW and 3kW systems, you could earn a lot more with this system.

Most expensive standard household system
A disadvantage of the 4kW solar system is that it’s the priciest standard domestic system. If you don’t have a huge budget for your solar panel system, the 4kW system is probably not your best option.
Will take up roof space
The 4kW system occupies a lot of roof space. It should take up 28m² approximately of roof surface, so it’s only really suitable for larger homes.
So are there both benefits and drawbacks to the 4kW solar system. If you want to install one and are looking for a professional to do it, we can help. Fill in our online form and we’ll put you in contact with up to 4 installers in your local area.
