We recently completed this 9.90 kWp solar PV and battery storage installation in Sissinghurst, Kent, providing the homeowner with a substantial renewable energy system designed to reduce reliance on grid electricity and make better use of the energy generated on their property.
The system consists of 22 Aiko N-Type ABC Neostar 450W solar panels, paired with a 9.4kWh Hanchu ESS battery storage system.
With the homeowner’s annual electricity consumption estimated at approximately 7,985 kWh, the system has been designed to provide a significant proportion of their annual energy requirements while giving them the ability to store surplus solar generation for use when the panels aren’t producing electricity.
The Solar PV System
The installation features:
- 22x Aiko N-Type ABC Neostar 450W solar panels
- 9.4 kWh Hanchu ESS battery storage
- Bird protection mesh
The Aiko N-Type ABC Neostar panels provide a high performance solar solution, while the 9.4 kWh Hanchu ESS battery provides additional storage capacity, allowing excess electricity generated during the day to be stored and used later.
This is particularly useful during the evening and overnight, when household electricity demand can continue even though the solar panels are no longer generating power.
Expected Solar Generation
Based on the property’s location and the proposed system design, the 9.90 kWp system is estimated to generate approximately 9,576 kWh of electricity in its first year. The homeowner’s annual electricity consumption is estimated at around 7,985 kWh, based on their electricity bill.
This means the solar installation is expected to generate more electricity over the course of a typical year than the property’s current annual consumption, although the timing of solar generation and household demand means the home will still import electricity from the grid at certain times.
The addition of battery storage helps address this by allowing surplus daytime generation to be retained for later use.
Predicted Financial Savings
The installation is expected to deliver significant long term savings on the homeowner’s electricity costs.
- Predicted year 1 savings: £1,857
- Estimated payback period: 8 years
- Predicted 30 year savings: £129,314
These figures demonstrate the potential long term value of combining a sizeable solar PV system with battery storage, particularly for a property with relatively high annual electricity consumption.
Actual savings will depend on factors including electricity prices, household consumption patterns, solar generation, battery usage and any income received from exporting surplus electricity to the grid.
Reducing the Property’s Carbon Footprint
As well as reducing electricity costs, the Sissinghurst installation will help the homeowner reduce their reliance on electricity generated from fossil fuels. The system is predicted to reduce carbon emissions by approximately:
- 1.92 tonnes of CO₂ per year
- 57.46 tonnes of CO₂ over 30 years
That’s the equivalent to planting approximately 91 trees every year.
Over the expected lifetime of the system, the cumulative carbon reduction represents a substantial contribution towards reducing the property’s environmental impact.

A Complete Solar and Battery Installation
As part of the project, SolarTherm UK handled the installation from start to finish, including the necessary scaffolding, bird protection and certification.
The installation also included the required G99 application, MCS certification and electrical certification, ensuring the homeowner received all the necessary documentation for their new solar PV and battery system.
The addition of bird protection mesh provides an extra layer of protection around the panels, helping to prevent birds from nesting underneath the array and protecting the installation from potential damage.
The Result
This 9.90 kWp solar PV system in Sissinghurst, Kent, gives the homeowner a substantial renewable energy system capable of generating an estimated 9,576 kWh of clean electricity every year.
Combined with 9.4 kWh of battery storage, the installation provides the homeowner with greater control over when they use the electricity their panels generate, while helping to reduce their dependence on the grid.
With predicted first year savings of £1,857, an estimated 8 year payback period and projected savings of £129,314 over 30 years, the system has been designed to provide both long term financial and environmental benefits.
