Renewal Home: Solar Power
What is Solar Power?
Solar power refers to the conversion of sunlight into electricity. This is typically achieved using photovoltaic (PV) panels that absorb sunlight and convert it into direct current (DC) electricity, which is then inverted into alternating current (AC) for home use. Solar energy is a renewable, clean energy source, making it a popular solution for reducing household carbon footprints and energy bills.
Typical Costs for an Average UK Household
2-bed house: £4,000 - £6,000 (3-4 kW system)
3-bed house: £5,000 - £8,000 (4-5 kW system)
4-bed house: £6,000 - £10,000 (5-6 kW system)
These costs cover the installation of the panels, the inverter, and sometimes a battery storage system.
Typical Payback Times
The payback time for solar panels depends on factors like household energy usage, location, and whether batteries are used.
For an average 3-bedroom house in the UK:
Without battery storage: Payback time is approximately 10-15 years.
With battery storage: Payback time can be 15-20+ years, as the initial investment is higher.
Advantages of Solar
Reduces energy bills, especially with high energy prices in the UK.
Lowers carbon footprint.
Excess electricity can be sold back to the grid (SEG).
Low maintenance with a typical lifespan of 25-30 years.
Drawbacks of Solar
High upfront costs.
Effectiveness depends on sunlight (less optimal in cloudy regions).
Solar panels take up roof space.
Energy storage (batteries) can increase costs
Is UK Weather Appropriate for Solar? Yes!
Costs Vs Expected Savings
Anticipated Reduction in Carbon Emissions
3-bedroom house: 583 - 815 kg CO2/year
4-bedroom house: 699 - 1,045 kg CO2/year
5-bedroom house: 815 - 1,165 kg CO2/year
This is just an estimate, and the actual savings could vary depending on the household's specific energy usage and the efficiency of the solar system.
