Solar System Case Study
Innovative Renewable Energy Solution Brings Efficiency and Comfort to Wells-Next-The-Sea, Norfolk Home
The Challenge
Remain Warm & Energy Efficient While Reducing Reliance on the Grid
Date of Completion: 23rd April 2024
System: 1 18 x 400w Solar Panels (7.2kW) + 5.2kWh Battery Storage


Wise Green Energy Ltd installed a 7.2kW solar system, and a 5.2kWh battery storage system alongside an Air-to-Air heat pump.
The Solution:
Solar PV Paired with Battery Storage and Air-to-air heat pump
complete energy control
7% return on investment in the first year
The air-to-air heat pump provides heating and cooling to the property and can be controlled remotely, allowing Sue to monitor and adjust settings from anywhere in the world. During the summer, the solar panels run the cooling system for free, while in the winter, the heat pump uses stored solar energy at a much lower cost, thanks to off-peak night tariffs from Octopus Energy (just 8p per kWh).
The Result
Reduced carbon Footprint
Sue now enjoys a significantly reduced carbon footprint, increased energy savings, and a more comfortable home environment. The system is performing as expected, with projected annual savings of £688, alongside export payments for excess energy. The integration of solar power, battery storage, and air-to-air heat pump technology creates a sustainable energy solution, offering a 7% return on investment in the first year, with further savings as electricity prices rise.
System Features & Benefits:
Solar PV System
- Reduces electricity bills and provides energy independence
- Supports heating and cooling for free during summer and winter months
- Earns revenue from exported energy, helping offset costs
- High ROI (7% net in the first year, linked to rising electricity prices)
- Contributes to the fight against climate change
- Promotes sustainability by using European-manufactured products
Battery Storage System
- Stores excess solar energy to use when the sun isn’t shining
- Allows for off-peak charging at a reduced cost, ensuring energy availability at a fraction of the normal price
- Empowers users to control energy use remotely via a smartphone app
Air-to-Air Heat Pump
- Provides heating, cooling, dehumidification, and air purification
- Improves indoor air quality, especially for those with allergies or respiratory issues
- Remote control for comfort and convenience, no matter where you are
- Efficient, even heat distribution using active air flow technology
