 Why go with JA Solar panels?

JA Solar are a manufacturer of n-type solar panels, which demonstrate superior performance and efficiency over the more common p-type construction. N-type panels are more resistant to degradation and generate on average 3.9% more electricity than p-type panels.

Where space is at a premium or maximum efficiency is essential, n-type are the superior choice.

Historically p-type panels were cheaper, but the gap is narrowing as the technology has advanced, making JA Solar’s n-type panels our recommended choice.

  • What are the best solar panels in the UK?

    We supply a range of solar panel brands. For new build projects we are an accredited Viridian installation company. Their in-roof panels are fire rated to UK standards and sit into the roof giving a sleek and aesthetically pleasing installation.  For existing roofs, we supply all black, tier one companies, such as Trina solar, Jinko and Sunpower.  These brands are known for their high efficiency, durability, and reliability, making them among the best options in the UK market.

  • How many solar panels do I need?

    It all depends on the number of people in your household, your energy consumption, and the available roof space.


    A typical three-bedroom house might have a 3kWh system made up of 7 or 8 tier one all black 430 watt solar panels. Typically, this would be expected to generate around 2,500 – 2,800 kWh per year.


    The most common systems that we install are 4 kWh, comprising around ten tier one all black 430 watt solar panels. Typically, this would be expected to generate around 3,600 kWh – 3,750 kWh per year.

    Our battery systems allow you to store excess solar energy to use in the evening, when typical usage is higher.


    You can also charge the battery from the grid, allowing you to make use of lower rates from off-peak tariffs

    A typical solar system can save between 50 and 70% on your energy bills. The precise numbers depend on your energy usage, electricity prices, the system size, and the orientation of your roof. For a south-facing roof based in and around Sheffield, a 4kWp solar PV array made up of ten, all black, tier one solar panels, would be expected to generate around 3,805 kWh per year.

  • How long until my solar panels break even?

    Your precise break-even point will vary according to system size, cost, energy consumption and tariff rate but during 2023, on average, you can expect to recover your installation costs from between 7 – 12 years domestically and 3-5 years for a larger commercial installation (12kWp-100kWp).
