01| Rising Electricity Costs
Electricity prices in the UK have been rising faster than the inflation rate, as illustrated by Ofgem’s recent price cap increases. The continual rise in electricity costs is crucial when deciding if a 15 kW solar system is the right choice for you.

03 | Electricity Savings
04 | 15 kW Solar System Price
The typical 15 kW solar system cost in the UK, excluding a battery, is around £19,000, including installation and VAT. The long-term savings and potential earnings from the Smart Export Guarantee can mitigate this upfront investment.
05 | How Many Solar Panels for a 15 kW System?
Modern solar panels have power ratings between 300W and 500W. Therefore, a 15 kW system would require between 30 and 56 individual panels, depending on the panel’s efficiency.
06 | How Big is a 15 kW Solar Array?
Each solar panel takes up about 1.6 square meters. Thus, a 15 kW solar system would need between 49 and 91 square meters of space, depending on whether you opt for more efficient (and usually more expensive) panels or less efficient ones.
07 | How Much Does a 15 kW Solar System Produce in the UK?
On average, a 15 kW solar system in the southern UK produces around 13,902.82 kWh annually. Several factors influence this output, including:
- Shading: Obstructions like trees or buildings can reduce efficiency.
- Location: Geographic location within the UK impacts sunlight availability.
- Roof direction and tilt: Optimal orientation and angle maximize solar capture.
- Time of year: Seasonal variations affect solar energy production.
- System efficiency: The overall efficiency of components plays a significant role.
08 | 15 kW Off-Grid Solar System in the UK
For those considering an off-grid solar solution, a 15 kW system could be a viable option. Important considerations include calculating the size of the battery needed to store energy for use when solar production is low. You would need to purchase between 30 and 56 solar panels, depending on their power rating.
Investing in a 15 kW solar system offers significant financial and environmental benefits for homes and businesses in the UK. With the rising electricity costs and government incentives like the Smart Export Guarantee, now is an excellent time to consider going solar. The initial 15 kW solar system cost and 15 kW solar system price in the UK may seem high, but the long-term savings and potential earnings make it a worthwhile investment.
A 15 kW solar PV system is an excellent choice for those looking to save money, reduce their carbon footprint, or gain energy independence. Evaluate your energy needs, consider your roof space, and explore the potential savings and earnings from solar power to determine if a 15 kW solar system is right for you. Remember to factor in the solar panels and battery cost when planning your investment.
