Solar Design Islington
Energy Usage
To choose the right solar system in Islington, start by understanding your daily electricity consumption. Whilst typical Islington households consume 15 kWh daily, homes with good insulation and modern appliances often use far less energy.
It's worth reducing your energy usage before going solar, as this can decrease the system size you need and improve payback. Focus on better insulation and energy efficient appliances.
Typical energy usage per person per day in Islington:
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. For best results, size your system between 5.9kW and 7.9kW to account for fluctuations in solar output throughout the day and year.
A 6.6 kW solar array in Islington delivers approximately 24.8 kWh daily, with generation varying seasonally from 2.08 kWh/kW/day in December up 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 Islington
Solar Battery Sizing
A 6.6 kW solar-only setup in Islington 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 Islington
Understanding Solar & Battery System Costs
Solar installation costs in Islington start at approximately £8,752 for a 6.6 kW system, with a 10 kWh battery bringing the total to around £13,557. Most solar-only systems reach payback in approximately 7.6 years, though battery storage lengthens payback periods whilst substantially boosting 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 Islington
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.
