How Much Do Solar Panels Cost? The average cost of a Solar System...

Solar panels have an average life expectancy of 25 years. At a quarter of a century, knowing your average energy usage as a home or business is about what’s cost-effective in the long run – not just immediately. Solar panel installation companies are experienced in this area and conducting a survey helps us to best understand your needs.

While there are no grants currently being offered, certain businesses are able to claim tax reliefs by switching to renewable energy. There are also funding options available if your business falls within the public sector. Local council, public swimming baths, schools, etc.

Domestic solar systems are designed specifically for each household, taking into account how much energy you use and when you use it, the system is then designed to provide you with the optimum benefits and savings.

We don’t offer packages of “X panels + Inverter for £XXX” as the cost varies depending on your property type and location. Set packages may not suit you or even fit on your property, for this reason we consider every enquiry on its own basis and advise on the most suitable system type and size of system.

As a guideline cost:

  • Basic spec. 3.6 kw system with 5kw battery storage starts from circa £8’000.00
  • High spec. 9.2 kw system with 10 kw battery storage starts from circa £18’000.00

Almost every solar system will at some time produce surplus energy, and there are several option of what to do with this energy.

The most common options being export it and get paid for it, transfer it to a battery and store it for later use or divert it to heat your water or charge your car.

There is also a Vehicle to grid system, where the battery in your EV can be used to store energy and discharge back into your property if the car is not being used.

For exporting from domestic properties, there is the Smart Export Guarantee (SEG) which allows you to sell excess energy back to the national grid via your electricity provider. However you must have a smart meter installed to measure how much electricity you are exporting, to qualify for SEG.

Good to know How Much Do Solar Panels Cost?...

Residential systems cost on average between £6’500 for a small solar system up to around £20’000 for a large system with battery storage. Solar panels can be fitted to most roofs.

To determine if solar panels are a good option for your home or business, start by looking at how much energy you use each month by looking at your energy bill, it should tell you how much energy you have used and how much you are being charged per KWh.

Households generally use between 5,000 and 10,000 kwh of electricity each year.

A lot of small to medium-sized businesses used around 30,000-50,000 kWh of electricity each year. This may fluctuate due to your size, and location in the UK.

A good way to estimate costs for residential systems is approx. £2,000 per KW for small systems down to £1,000 per KW for large systems. Batteries start from around £2’000

If you run a very small business the same approximate rules may not apply and it may be best that you get in touch to gather a more accurate estimate.

As a business owner, you may be able to claim tax relief if you have commercial solar panels installed. Keep in mind that is not possible for businesses that rely on solar energy for their revenue generation, such as a solar farm for example.
