Project Overview
SolarTherm UK recently completed a solar panel installation in Harwich, Essex, helping the homeowner take greater control of their electricity costs with a high performance solar PV system and battery storage.
The installation features an 8.46 kWp solar PV system comprising 18 Aiko Neostar 2S Mono-glass 470W solar panels, paired with a 9.4 kWh Hanchu ESS battery. Designed around the property’s estimated annual electricity consumption of 9,000 kWh, the system is expected to generate approximately 7,740 kWh of renewable electricity each year.
With predicted first year savings of £2,037 and an estimated payback period of just five years, this installation demonstrates the potential financial benefits of combining solar panels with battery storage.
Maximising Solar Energy with Battery Storage
With an estimated annual electricity consumption of 9,000 kWh, the homeowner in Harwich has a significant demand for electricity throughout the year. Installing an 8.46 kWp solar PV system provides an opportunity to generate a substantial proportion of this electricity directly from renewable energy.
The 18 Aiko Neostar 2S Mono-glass 470W solar panels are expected to produce approximately 7,740 kWh of electricity annually, helping to reduce the amount of energy required from the grid.
To make even better use of the electricity generated, the system includes a 9.4 kWh Hanchu ESS battery. Battery storage allows surplus solar energy generated during the day to be stored for use later, such as during the evening when household electricity demand may remain high but solar generation has decreased.
By combining solar generation with battery storage, the homeowner can make better use of their own renewable electricity and potentially reduce reliance on imported grid electricity.
Predicted Financial Savings
One of the key benefits of this installation is its projected financial return. Based on the system’s estimates, the Harwich homeowner could save approximately £2,037 in the first year.
With an estimated payback period of five years, the installation offers the potential for a relatively short return on the initial investment, followed by many years of reduced electricity costs.
Over the minimum 30 year lifespan of the system, it is predicted to deliver a total saving of approximately £175,960.
These figures are projections rather than guaranteed returns. Actual savings will depend on future electricity prices, household consumption patterns, solar generation, battery usage and any applicable export payments.
A More Sustainable Home in Harwich
As well as helping to reduce electricity bills, this installation is expected to make a meaningful contribution to lowering the property’s carbon footprint.
The system’s estimated environmental benefits include:
- Annual CO₂ reduction: 1.54 tonnes
- 30 year CO₂ reduction: 46.44 tonnes
- Equivalent to planting approximately 73 trees per year
By generating clean electricity from sunlight, the homeowner can reduce their reliance on conventional grid electricity and support a more sustainable energy future.
Professional Installation and Complete Certification
As part of the installation, SolarTherm UK included the additional work and documentation required to complete the project professionally.
The installation package included:
- Scaffolding to provide safe access to the roof
- Bird protection mesh to help prevent birds from nesting beneath the solar panels
- G99 grid connection application
- MCS certification
- Electrical installation certificates
These provisions help ensure the installation is properly documented, with the relevant certification and grid connection requirements addressed.
