Solar, Battery & EV Charger Installation in Woking, Surrey

The result

A 10.1 kWp solar and battery system designed to reduce grid reliance and future-proof a four-bedroom family home in Woking.

The system combines 25 AIKO Neostar solar panels with a Fox ESS hybrid inverter and 11.52 kWh battery, alongside a Zappi EV charger for the customer’s new electric car. It is predicted to generate 7,572 kWh of electricity a year, with approximately 71% of the solar generation expected to be used within the home.

Phase Energy estimated a year-one financial benefit of approximately £1,672.

At a glance

The customer’s objective

The homeowner approached Phase Energy after solar installations had already been completed for two close family members.

They wanted to reduce their household electricity bills, become less reliant on grid electricity and future-proof the property. With a new electric car also forming part of the household’s plans, EV charging was incorporated into the overall project.

The Phase Energy solution

Phase Energy designed a solar, battery and EV charging system comprising 25 AIKO Neostar 460W panels, a Fox ESS KH 10 kW hybrid inverter and a Fox ESS EP12 11.52 kWh battery.

A Zappi EV charger was also installed to provide convenient home charging for the customer’s electric vehicle.

Together, the system allows electricity generated on the roof to be used directly within the home, stored for use later or used to help charge the vehicle.

Why the system was designed this way

The solar array was positioned across the available south-facing roof areas to make productive use of the property’s strongest solar aspects.

The number of panels was also influenced by the available inverter string inputs, while the 11.52 kWh battery capacity was selected in relation to the household’s electricity consumption.

The result is a system designed around both the home’s current energy requirements and its future use as electric vehicle ownership increases household electricity demand.

Installation

The installation was completed over two days.

There were no significant roof, access or electrical complications recorded for this project, allowing the solar array, battery system and EV charger to be installed as planned.
