Organic solar cells are the next step for solar energy, making this technology affordable for more people due to the solar cell price reduction of solar cells. Even though the organic solar cell technology is still new, the estimated cost of manufacturing for purely organic solar cells will range between £30 and £90/m2.
The average package 3kW or 4kW solar panel system with battery, usually comes with a 4kW to 14kW battery. The average price of a solar panel system and battery ranges from £8,500 - £14,000 but can be considerably higher depending on the battery. If you want to include a storage solution you are going to have to pay more upfront.
As the average cost of a solar battery for a three-bedroom house is £4,500, it means you could pay £9,000, or more for batteries over the lifespan of your solar panels. The average package 3kW or 4kW solar panel system with battery, usually comes with a 4kW to 14kW battery.
A typical 4kW solar panel system for 2-3 bedroom houses costs £5,000 - £6,000 with installation. Added together, the total cost of solar panels and a battery in the UK is £13,000 - £15,500. A 4kW system breaks even in 7 - 10 years, with annual electricity cost savings of between £440 and £1,005.
Solar cell price is still too expensive for everyone to benefit from because of the great use of solar power in solar panels. The main material which composes most of the today’s solar cells is crystalline silicon, with an efficiency of most common solar panels of approximately 10 percent.
Starting with some base figures, solar systems in the UK start around the £3500 mark but often top out at £20,000. To put that in perspective, let’s look at a case study of a typical UK house. Please note: these figures don't consider the average annual (est. 3.6-10%) increase in electricity costs from providers.
