Solar Design Hillingdon
Energy Usage
Your daily energy consumption determines the optimal solar system size for your home in Hillingdon. The average household uses around 15 kWh per day, whilst energy efficient properties may use only half that.
Consider reducing your energy consumption first through better insulation and efficient appliances, as this can reduce the solar system size needed and improve your investment returns.
Typical energy usage per person per day in Hillingdon:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
A solar system sized at approximately 3.9kW would cover your typical daily energy needs. Systems sized between 5.9kW and 7.9kW perform best, accounting for natural fluctuations in solar production.
In Hillingdon, a 6.6 kW installation produces around 24.8 kWh per day on average, though output ranges from 2.08 kWh/kW/day during December to 4.63 kWh/kW/day in August.
Solar & Energy Savings
Calculate Heat Pump & EV Savings
Electrify your home by replacing gas heating, petrol vehicles, and other fossil fuel appliances with electric alternatives powered by clean solar energy. This delivers significant additional financial savings and substantial carbon emission reductions. Our calculator helps you compare costs and model the financial impact of switching to electric appliances and vehicles.
How Solar Reduces Your Electricity Bills
The calculations below show how your electricity bills change with solar. Your Old Bill of - per month (- annually) is calculated from your total energy consumption multiplied by the grid electricity rate. Your New Bill of - per month (- annually) accounts for solar generation, the percentage you use directly (self-consumption), remaining grid consumption, and feed-in credits for excess energy exported to the grid. This results in monthly savings of - (- annually).
Battery Storage Hillingdon
Solar Battery Sizing
A 6.6 kW solar-only setup in Hillingdon delivers around 45% self-sufficiency, leaving 55% dependent on grid electricity. Including a 10 kWh battery typically raises annual self-sufficiency to around 95%, with grid reliance dropping to 5%.

Solar & Battery System Cost Hillingdon
Understanding Solar & Battery System Costs
Solar installation costs in Hillingdon start at approximately £8,752 for a 6.6 kW system, with a 10 kWh battery bringing the total to around £13,557. Solar installations typically pay for themselves within around 7.6 years, whilst batteries extend payback but deliver significantly higher energy independence.
The cost breakdown shows estimates for equipment costs, installation labour, and applicable taxes. Adjust system size and battery storage to see how it affects total investment and payback periods.
Solar Rebates & Incentives Hillingdon
While there are currently no federal government rebates for solar panel installations in the UK, there are still financial benefits available for solar system owners.
The Smart Export Guarantee (SEG) allows you to earn money by selling excess solar electricity back to the grid. Energy suppliers with more than 150,000 customers are required to offer SEG tariffs, which pay you for the renewable electricity you export. Rates vary by supplier and are typically set competitively.
Additionally, installing solar panels can significantly reduce your electricity bills by generating your own renewable energy. The savings depend on your energy consumption patterns and system size, but many homeowners see substantial reductions in their energy costs.
