How Much Does it Cost to Have 4kw Solar Array Installed in the UK

The costs for installing a 4kW solar array in the UK have never been lower. Plus, you can earn money from the 16p Feed-In Tariff.

4kW Solar Array

A solar array is another term to describe a solar panel system or even a photovoltaic array, and refers to a number of solar panels connected together to form a solar PV system. A typical 4kW solar array would consist of several solar panels connected together to achieve as close to 4kW as possible.

Configurations of 21 x 175w panels providing 3675 watts are still sold as 4kW systems although closer configurations such as 21 x 190w modules delivering 3990 watts are also common as well as 17 x 235w giving 3995 watts and being the closest to 4kW out of the three. Be mindful of these differences when shopping around for price.

It will cost between £8,000 and £12,000 to have an MCS approved 4kW solar array installed in the UK and this price includes all of the components required for a grid-tied system which will work alongside mains electricity. Here are some sample returns you may be able to get with a new solar system:

MCS Accreditation

The Microgeneration Certification Scheme (MCS) is an industry led organisation given the responsibility, by the Department of Energy and Climate Change, to accredit and approve solar companies and products. This accreditation and approval is to ensure that a high standard of solar panel products and services are encouraged throughout the UK.

Consequently, only MCS accredited companies are able to supply and install solar products that can earn homeowners cash for all the electricity produced. Feed in Tariffs for renewable energy or FITs were created to incentivize as many homes and business as possible by paying up to 16p for every kW hour of electricity produced by solar panels. Only MCS approved solar panels are eligible and only MCS accredited companies can supply or fit them.

Pay for Quality

It is important to ensure that you are using a bona fide solar panel supplier that can supply and fit a quality MCS approved 4kW solar array. Do not agree to pay anything unless you have seen proof that the solar panels being used are actually MCS approved and that the company fitting them is MCS accredited.

It is better to pay a little more for a high quality solar array that can potentially earn you thousands of pounds each year from Feed in Tariffs and also efficiently save you money on your electricity bills by generating free solar electricity.

How to Find the Best Solar Array Supplier

There may be unscrupulous companies that try to lure unsuspecting consumers by extravagant advertising campaigns designed to provide you with low grade equipment for what would appear to be competitive prices. To be certain that you are getting the best value for money from a reputable solar panel supplier it is best to leave the leg work to a highly experienced solar panel comparison website that already knows the top solar energy companies in the UK.

These websites (such as The Eco Experts) have state of the art online systems in place that can compare and review many of the top MCS accredited companies around the UK and can provide you with a selection of well established suppliers. Then, you can compare 4kW solar array prices in the confidence that only the best MCS products and companies are being considered.

How Long Does Solar Panel Installation Take?

Solar installation has become big business in the United Kingdom in the last few years. The actual time taken to install solar panels obviously depends on the size of the system being installed. However, as a general rule an average domestic system can be installed in 2 to 3 days.

The vast majority of solar panel systems are installed on to rooftops. Companies installing the technology will erect the scaffolding for the work on the first day. They will then inspect the roof to ensure that there are no weak links or problems which could hamper the installation process. During the second, and sometimes third day, the panels will be fixed on to the roof and then wired up.

So How Much Does Solar Panel Installation Cost?

Solar installation is not cheap by any means and the initial cost can run into thousands of pounds. Again, it depends on the size of the system being installed as to the overall cost. However, as a general rule solar panels cost between £2,000 and £3,000 per kilowatt (kW).

The smallest domestic solar panel systems are 2kW, so the least you can expect to pay is £4,000. For a 4kW solar array you can expect to spend between £8,000 to £12,000 depending on your location. Commercial solar panel systems can run into the tens of thousands although they will obviously create much more electricity.

However, be sure to speak to several solar installers in your area before making any final decision.
