Residential Solar PV and Battery Installation in Fareham

Completed July 2026

A carefully integrated and expansion-ready solar and storage system designed to reduce the household's exposure to rising energy costs, lower grid reliance and provide a flexible platform for additional battery capacity and future solar panels.

Project overview

For this Fareham homeowner, the project was about more than generating renewable electricity. A key consideration was reducing exposure to future energy price increases by producing more energy on site, storing surplus generation and creating the flexibility to buy lower-cost electricity during off-peak periods. The system was therefore designed as an expandable home energy platform rather than a fixed, one-off installation.

The brief

The homeowner wanted greater control over energy costs, stronger self-consumption and a system that could grow with the property.

An important consideration was minimising the household's exposure to rising electricity prices. The customer wanted to use solar generation and battery storage to reduce the amount of energy purchased at peak rates, while also retaining the option to charge the battery from a lower-cost off-peak tariff during winter when solar production is lower. The installation also needed to support future battery expansion and additional solar panels when the conservatory roof is replaced.

The solution

Bespoke PV designed a complete solar, storage and electrical integration package.

Bespoke PV designed a 7.735 kWp system using 17 high-efficiency Trina Solar panels across two roof elevations. A FoxESS KH10 hybrid inverter and FoxESS EP12 Plus battery provide solar storage and flexible tariff-based charging. The inverter and battery location was deliberately selected to preserve space, access and cable routes for additional battery modules. Dedicated isolation, surge protection, grid/EPS changeover switching and clearly labelled distribution equipment complete the installation.

Designed for future expansion

The installation was planned as the first stage of a longer-term home energy strategy.

Additional battery storage The inverter and battery location was selected to leave suitable space, access and cable routes for further battery capacity.

Off-peak winter charging The customer plans to charge the battery on a lower-cost off-peak tariff during winter and use the stored energy during more expensive periods.

Future conservatory solar When the existing conservatory roof is replaced, additional panels are planned to increase annual generation and self-sufficiency.

Installed system

The final specification combines generation, storage and backup-ready electrical infrastructure.

Solar Array 17 x 455 W Trina Solar modules delivering 7.735 kWp total capacity

Hybrid inverter FoxESS KH10, 10 kW

Warranties 25-year panel product, 30-year panel performance, 10-year inverter and battery warranties

Projected performance

The original proposal modelled the system using the MCS methodology. These figures are estimates rather than guarantees.

Battery storage is projected to increase solar self-consumption and materially reduce grid dependence. This helps shield the household from rising electricity costs by reducing the volume of energy purchased at standard or peak rates.

5,611 kWh Projected annual generation

157% Consumption offset

57% Projected solar self-consumption

43% Projected export to grid

3,197 kWh Projected solar self-consumption with battery

89% Projected grid independence with storage

£800 Estimated first-year bill savings

£30,273 Projected lifetime bill savings

14 years Projected payback

1 tonne per year Projected CO2 reduction

Why the design works

The strength of the project is not only the hardware, but how the whole system has been brought together.

Dual-roof layout
Using two roof elevations helps spread generation and make effective use of the property's available roof space. Battery-led self-consumption
Stored solar energy can be used later in the day, reducing evening and overnight imports from the grid. Winter off-peak charging
When winter generation is lower, the customer plans to charge the battery at lower off-peak rates and use that energy during more expensive periods. Expansion-ready battery location
The equipment position preserves suitable space, access and cable routes for additional battery capacity. Future conservatory array
When the conservatory roof is replaced, additional panels are planned to increase generation and self-sufficiency. Backup readiness
Grid/EPS changeover and protected circuits create a structured route for maintaining selected loads during an outage.

The outcome

The completed system gives the customer several ways to manage energy costs: generating electricity on site, storing surplus solar for later use and charging the battery during lower-cost off-peak periods in winter. Its expansion-ready layout also means additional battery storage and a future conservatory solar array can be added without treating the original installation as a closed or isolated system.

Important note

All performance, savings and carbon-reduction figures are projected values from the original proposal and should be treated as estimates rather than guarantees. Actual results will vary according to occupancy, weather, shading, tariff choice, battery operating strategy and future system expansion.
