Solar & Battery Installation Cambridge Local Installers & Quotes
Solar panels perform well in Cambridge, with production peaking during August and remaining useful even in December. For a typical household using 15 kWh per day, solar can substantially lower electricity bills and provide greater energy independence.

Energy Usage
Homes in Cambridge using around 15 kWh daily face significant electricity costs — and solar can substantially reduce them, especially as energy prices continue rising. Whilst typical Cambridge households consume 15 kWh daily, homes with good insulation and modern appliances often use far less energy.
Reducing your energy consumption before installing solar can lower your system size requirements and improve returns. Consider upgrading insulation and switching to energy efficient appliances first.
Typical energy usage per person per day in Cambridge:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
You'll need around 3.9kW of solar to match your average consumption. Going larger within the 5.9kW to 7.9kW range typically improves long-term value, since solar panels produce well for 25 years or more.
A 5.9 kW system in Cambridge generates approximately 22.0 kWh daily on average, with seasonal variation from 2.02 kWh/kW/day in December to 4.62 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 Cambridge
Solar Battery Sizing
Reducing that 55% grid dependency with a battery can deliver meaningful savings, especially if your area has time-of-use tariffs where evening rates are higher. With a 10 kWh battery, your 5.9 kW system can power your home well into the evening, bringing grid reliance down to approximately 11%.
The best way to see whether a battery makes financial sense for your Cambridge home is to model it with your actual usage — try the full Photonik design tool for a personalised estimate.

Solar & Battery System Cost Cambridge
Understanding Solar & Battery System Costs
Solar systems in Cambridge are priced around £9,682 for a 5.9 kW installation, rising to approximately £18,507 when including a 10 kWh battery. After the 9.0-year payback period, your solar system continues producing — at current rates, that's potentially 15+ years of savings with minimal maintenance costs.
Try adjusting the system size and battery sliders above to see how different configurations affect both upfront cost and long-term savings for your Cambridge home.
Solar Rebates & Incentives Cambridge
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.
