Energy Usage

Understanding your household's energy usage is essential for sizing a solar system in Birmingham. Typical homes consume approximately 15 kWh daily on average, though well-insulated properties with efficient appliances often use significantly less.

Every kWh you save through efficiency improvements is worth real money — and also means you need fewer solar panels to cover your remaining usage.

Typical energy usage per person per day in Birmingham:

Low (Efficient)
~3 kWh
Medium (average)
~4 kWh
High (intensive)
~6+ kWh

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. In Birmingham, sizing between 5.9kW and 7.9kW gives a good balance between covering your usage and getting the best return on investment.

A 5.9 kW solar array in Birmingham delivers approximately 22.0 kWh daily, with generation varying seasonally from 2.00 kWh/kW/day in December up 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 Birmingham


Solar Battery Sizing

At around 45% self-sufficiency without a battery, you're still buying 55% of your electricity from the grid — mostly in the evenings and overnight when solar isn't generating. The jump from 45% to 89% self-sufficiency with a 10 kWh battery is most noticeable on your evening electricity bills, when rates are often highest.

Battery economics depend on your specific tariff structure and usage patterns — the Photonik design tool can model these scenarios with your actual electricity plan.

0 kWh 30 kWh

lightbulb A 0kWh battery will make you about 0% self sufficient.

The sweet spot for most households is 5 – 13 kWh — larger batteries add independence but with diminishing payback, especially where feed-in tariffs are low.

Solar & Battery System Cost Birmingham


Understanding Solar & Battery System Costs

A 5.9 kW solar system in Birmingham is priced at approximately £9,682, whilst adding 10 kWh of battery storage increases the total investment to around £18,507. Payback periods for solar-only installations average approximately 9.0 years, whilst battery storage extends payback but significantly improves energy independence.

Pricing includes equipment, labour, and taxes. Use the sliders to adjust system size and battery capacity, observing how changes impact total cost and payback.

Solar Rebates & Incentives Birmingham


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.
