Project Summary

A homeowner on the outskirts of Peterborough contacted Optimum Electrics after being recommended by a previous customer who had recently benefitted from solar and battery storage. Following an initial consultation and energy assessment, our team designed a future-proof solar solution that would support both current and upcoming energy demands — including a hybrid vehicle and planned heat-pump installation.

The completed system now enables the homeowner to significantly reduce reliance on the grid and take full control of their energy usage, day and night.

Customer Goals & Key Drivers

The homeowners had been considering solar for a while, but following a strong recommendation from a friend — and seeing the savings first-hand — they decided it was the right time to invest.

Their priorities were clear:

Reduce energy bills as electricity usage had risen due to a hybrid vehicle and recent home extensions.
Future-proof the property in preparation for switching to a heat pump within the next two years.
Maximise self-consumption and minimise reliance on imported grid energy both during the day and night.

Design Requirements

Single-phase property
Two south-facing roofs — ideal for solar generation
Clean aesthetics and minimal disruption to indoor space
External installation of inverter and batteries

Our Solution

Optimum Electrics designed and installed a 7.05kW Solar PV & Battery Storage system using premium, high-performance components:

Component	Description
15 x 475W AIKO Neostar All Black Panels	Ultra-efficient, sleek aesthetics, high performance in low light
1 x 8kW Sigenergy Hybrid Inverter	Smart, powerful inverter enabling seamless energy conversion and battery management
2 x 9kWh Sigenergy Batteries (18kWh total)	Large storage capacity for maximum self-consumption
Bird Protection Meshing	Prevents nesting and protects the long-term performance of the system

The inverter and battery system were mounted neatly on the external side wall of the property, ensuring easy access and keeping internal space clear.

Results & Benefits for the Customer

Reduced energy bills by generating and storing clean electricity.
Night-time usage powered by the batteries, reducing reliance on peak-rate grid energy.
Future-proofed for the planned heat pump upgrade.
Cleaner carbon footprint and improved home efficiency rating.
