A measure of how efficiently a solar system converts sunlight into usable electricity. It’s the ratio of actual energy output to the system’s theoretical maximum output, as a percentage.
Performance Ratio:
89%
The time it takes for a solar panel system’s energy savings to equal the initial installation cost. It’s calculated by dividing the total cost by annual savings from reduced energy bills.
Estimated Payback Period:
5.6 Years
The predicted amount of money a household or business saves on energy bills each month after installing a solar power system, based on energy production.
Estimated Monthly Bill Saving:
£328.47
The predicted amount of money a household or business saves on energy bills annually after installing a solar power system, based on energy production.
Estimated Annual Bill Saving:
£3,941.66
The total amount of money saved on energy bills over the entire lifespan of a solar system, accounting for installation costs and energy production.
Estimated Net Lifetime Bill Saving:
£72,385

Predicted Impact:
The total amount of electricity a solar power system generates in a year, typically measured in megawatt-hours (MWh), based on the system’s size and sunlight exposure.
Annual Energy Production:
16.10MWh
The total direct current (DC) capacity of a solar power system, measured in kilowatts (kW), based on the combined output of all the solar panels under ideal conditions.
Installed DC Power:
18.68kWp
The highest amount of alternating current (AC) electricity a solar power system has produced at any given time, typically measured in kilowatts (kW), after conversion from DC.
Max Achieved AC Power:
10kW
The amount of carbon dioxide (CO2) a solar power system prevents from being released into the atmosphere each year by replacing electricity generated from fossil fuels, measured in tons.
Annual CO2 Emissions Saved:
3.11t
The number of trees needed to absorb the same amount of CO2 emissions that a solar power system prevents each year, illustrating the environmental benefit in tree terms.
Blackford Village Hall, a charitable community space managed by a committee of Trustees, sought to reduce its reliance on the grid and enhance its sustainability efforts.
Project Scope:
Installation of a 18.68kW state-of-the-art solar photovoltaic (PV) system with a 9.2kW battery.
Solution Implemented:
Sunlit Solar designed and installed a custom solar PV array for the village hall, maximising energy generation and storage so that energy made in the day could be used for any evening functions.
Results Achieved:
Clean Energy Generation:
The installed solar PV system is projected to produce an estimated 16.10MWh of clean energy annually.
Carbon Emissions Reduction:
Blackford Village Hall expects to cut carbon emissions by 3.11 tons annually, in line with their commitment to environmental sustainability.
Operational Efficiency:
By utilising solar energy and battery storage, the Blackford Village Hall is set to reduce its dependence on traditional energy sources, resulting in long-term cost savings and improved operational efficiency.
