12kW Solar Panel System

Why 12kW Solar Panels Could be Right for You

Are you interested in switching to solar energy, but worried that it might not fulfil your power needs? 12 kW solar panel systems are the right choice for you if you need to power a larger home or property.

12 kW solar systems are very large and will mean the number of solar panels you need to produce a significant amount of electricity is higher than normal. This sized system is usually utilised for commercial rather than domestic purposes. However, if your energy demand is high, this solution will satisfy your needs while making your house more eco-friendly.

What's more, is that you can earn money for surplus energy exported back to the grid under the Smart Export Guarantee.

12 kW solar panel systems are a good solution for homes bigger than the average. The size of the system allows it to generate the right amount of electricity required to meet the daily needs of a large household. Keep in mind that 12 kW solar system is quite big and you will likely need around 75 m2 free roof space.

How Much Does a 12kW Solar Panel System Cost?

It is difficult to set a fixed price for the system, but it is sensible to say that the expected investment would be starting from around £13,000, however, their significant energy output gives them one of the quickest payback periods.

Smart Export Guarantee

The Smart Export Guarantee is a UK-based scheme that enables you to earn money through your panels. If you generate a surplus, you can sell that electricity back to the grid. The rates vary from energy supplier to energy supplier, so it's advised you do your research before choosing which one to go with.

Feed-In Tariff

The Feed-in Tariff was a UK government solar panel scheme that rewarded homeowners for both production as well as exporting surplus energy. This scheme closed in April 2019, and no new applications are accepted.

Though, when it comes to the Feed-in Tariff, you have to bear in mind that the tariffs can vary. Usually, the bigger the system, the smaller the rate is, as larger systems generally produce more electricity. However, from a long-term perspective, your system will be generating more in quantity of electricity. The FiT rate would be slightly lower, which would naturally lead to greater savings.

How Much Electricity Does the System Produce?

The performance of your 12 kW solar system depends on several things such as the direction your roof is facing, its angling and of course the quality of the materials used. Maximum power will be achieved with an unobstructed south-facing view of the sun. Some efficiency losses might derive from weather conditions or some shading over your panels. A 12 kW system produces an estimated 900 to 2000 kilowatt hours per month, assuming at least 5 sun hours per day with the panels facing south.

How to Choose the Right System

A 12 kW solar panel system requires a significant investment, therefore you will need to research and compare your options. Of course, this can be quite difficult and could take a long time. If you need assistance in your research process, look no further, with GreenMatch you will be able to compare different suppliers in a moment.
