6kW Solar Panel System

Why 6kW Solar Panels Are a Great Option in the UK

6kW solar panel systems are designed to power large homes or properties, housing families of 5 people. This solution will guarantee your energy demand as well as making your house more eco-friendly. The size of the system allows it to generate just about the right amount of electricity required to meet the daily needs of a large household.

How many solar panels you need for this sized system depends on the wattage of the individual panel. Typically, a 6kW solar panel system using 250 watt panels will require 24 solar panels.

Keep in mind that 6kW solar panel systems are quite big and you will need more than 38 m2 free roof space, plus a little extra room in your attic (usually for the inverter used to convert the current into a usable one). In return for this investment, a 6kW solar panel system can supply an ample amount of free electricity to help you save big on your utility bills.

How to Find the Best Solar Panels in the UK (Cost & Efficiency Guide 2021)

How Much Does a 6kW Solar Panel System Cost?

It is difficult to set a fixed price for a 6kW solar system, but it is sensible to say that the expected investment would be starting from around £7,000. 6kW solar panel systems can easily go above £8,000, however, their serious energy output gives them one of the quickest payback periods. More information can be provided from your supplier, which has to be MCS certified if you are to qualify for the feed-in tariff.

Feed-in Tariff

Before the Feed-in Tariff (FIT) ended in April 2019, the tariff rates were an added incentive for installing domestic solar PV systems. Those that are registered under the FIT scheme will continue to receive these payments, however no need applications are being processed.

Smart Export Guarantee

The Smart Export Guarantee (SEG) is a new type of solar panel funding that is available in the UK. Under this scheme, energy suppliers with over 150,000 customers are obligated to offer an export tariff for electricity fed back to the National Grid. Energy suppliers with fewer customers can offer the tariff on a voluntary basis. 

Making use of this kind of a scheme can reduce your overall solar panel costs.

How Much Electricity Will the System Produce?

The performance of your 6 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.

With a south facing roof and the right angling, the system will generate approximately 4.5 kWh for each kW installed, minus some minor losses that are likely to occur. Such efficiency losses might appear from weather conditions or some slight shading over your panels.

In brief, these are some of the main factors that will define the power output of your system:

  1. Geographic location will affect the daily solar irradiation and will define the potential output of the system. The sunnier, the better.
  2. Are there trees or any other object creating shade over the solar array? Panels should be as free of shade as possible, to achieve the maximum potential of the solar array. When a panel or panels are blocked by the shade of a tree, for example, you are wasting a valuable portion of your array!
  3. Orientation and tilt angle of the solar panel array. Optimal positioning of the panels will ensure the most amount of sunlight can be absorbed.
  4. Performance and features of the individual components. Not all brands have the same energy efficiencies and not all inverters are the same. Check this with your solar installer. 

How to Choose the Right 6kW Solar Panel System?

A 6kW solar panel system can be quite expensive, therefore, you will need to do a thorough research and compare your options. With all the different options and technical factors influencing your purchase, it can be difficult and time-consuming to make a purchase decision all by yourself.
