Installing solar panels is a great way to generate your own electricity. They’re usually fitted on the roof of your house and use energy from the sun to make electricity and power your home. There are several different sized solar panel systems, so you can choose a suitable one for your property.

The 2kW solar panel system needs around 14m² of roof space. It generates about 1700kWh of electricity per year, which is more than enough to power an average kitchen for a whole year.

But is the 2kW system the best solar panel system for you? To help you decide, we’ve compiled a list of its pros and cons.


Generates free electricity

A great benefit of solar panel systems is that they generate free electricity. Sunlight is free, so the electricity that it creates is also free. Installing solar panels is a fantastic chance to generate free electricity, especially given the high charges that many power suppliers impose.

Lowers your carbon emissions

Installing solar panels will also help you lower your carbon emissions. The generation of most mains electricity contributes to carbon levels in the atmosphere. But the generation of solar power doesn’t. So by using solar power instead of electricity from the mains, you’re reducing your carbon footprint.

Reduces your electricity bill

Generating power through solar panel systems can also lower your electricity bill. This is because the free solar power that you generate replaces the electricity that you buy from your power supplier. So having a solar panel system reduces how much electricity you need to pay for and reduces your electricity bill.

Earns money

Solar panel systems also provide you with the opportunity to earn money. The government’s Feed-in Tariff scheme will pay you for the power that your solar power system generates, even if you use it.

You can also make money by selling any electricity you generate but don’t use back to the mains. You will get paid a rate per unit for this.

Because 2kW systems generate more electricity than 1 kW systems, your overall profit could be 5 times more than if you had a 1kW system.

Cheaper than some systems

A great reason to install a 2kW solar panel system is that it’s one of the cheaper domestic solar panel systems available. It’s less expensive than both the 3kW and the 4kW system. So if you want to install solar panels but don’t want to pay too much upfront, you may want to choose a 2kW system.


More expensive than the 1kW system

A downside to the 2kW solar panel system is that it’s more expensive than the 1kW system. So if you want the cheapest short term option, the 2kW system probably isn’t for you.

Relatively small profit

The 2kW system only produces a relatively small profit. Bigger systems cost more, but they produce a larger long-term profit. A 2kW system will earn you half what you could make with a 4kW system. So if you want to earn as much money as possible, you should consider installing a bigger system.
