Properly utilized, a 20kW solar system can save approximately £2,836 annually by offsetting electricity costs. The 20kW solar system price (without a battery) is typically around £25,000 in the UK, including installation and VAT. This initial 20kW solar system cost in the UK can quickly be recovered from the long-term benefits.
The average cost to install a residential solar installation, according to the National Renewable Energy Lab, is $2.93 per watt. So, a 20 kilowatt installation that you pay for in cash upfront would total around $58,600! That’s a staggering number, to be sure!
Investing in a 20kW solar system can bring significant financial benefits, particularly if you reside in an area with ample sunlight. With the potential to generate $6,205 worth of electricity every year, a 20% return on investment can be achieved based on the current costs of panels ($40,000 for this system).
In the South of the UK, a 20kW solar system produces around 18,537.09 kWh annually. However, several factors influence this output, including: Geographic location within the UK. Roof direction and tilt. Time of year. Efficiency of the system components.
First things first, a 20 kW solar installation is BIG! The average home solar installation in the United States is 5.6 kW, so a 20 kW system is almost 4 times bigger!
For those considering an off-grid 20kW solar system in the UK, it’s crucial to calculate the required battery size to store the generated energy. You can then purchase the 40 to 74 panels needed for the system.
