Sunhome Completes 6.3 kW Solar and Battery Storage System in Surrey
Sunhome delivered a 6.3 kW residential solar PV and 15 kWh battery storage system at a property in Surrey.
The installation combines 14 Sungrow 450W Full Black solar panels with a Sungrow 5 kW hybrid inverter, three 5 kWh battery modules, a Sungrow EV charger and K2 mounting components on a south-facing pitched clay-tile roof.
Supplied by Alternergy as an integrated Sungrow energy solution, the system was designed to increase the homeowner’s use of self-generated electricity, reduce reliance on the grid and simplify the management of solar generation, battery storage and EV charging.

Project Overview
The resulting system combines rooftop solar PV with battery storage and EV charging, allowing electricity generated during the day to be used directly, stored for later or used to support electric vehicle charging.
Solar and Battery System Design
The hybrid inverter manages energy flows between solar generation, battery storage, household loads and the grid.
Installation and Commissioning
As an integrated Sungrow system, commissioning and setup could be carried out through the Sungrow platform.
Once commissioned, iSolarCloud gives the homeowner visibility of solar generation, battery performance, household consumption and connected energy equipment through one monitoring platform.
Customer Testimonial:
"I am absolutely delighted with my solar panels and battery system. I have seen an immediate benefit from lower energy costs, and the satisfaction of relying far less on energy companies is extremely rewarding." - Homeowner, Surrey

Customer Testimonial:
"I am absolutely delighted with my solar panels and battery system. I have seen an immediate benefit from lower energy costs, and the satisfaction of relying far less on energy companies is extremely rewarding. Knowing that I am helping to reduce carbon emissions and contribute towards a sustainable future was a key reason for installing the system. The installation was seamless and professional, and the team were helpful, polite, and supportive throughout." - Homeowner, Surrey
01
6.3 kW Rooftop Solar PV
Fourteen PV modules generate renewable electricity from the property's south-facing roof.
02
15 kWh Battery Storage
Battery storage allows surplus solar generation to be retained for use later in the day.
03
iSolarCloud Monitoring
Real-time monitoring gives the homeowner visibility of generation, storage, consumption and system performance.
Solar and Battery Storage Benefits
Solar PV generates electricity during daylight hours, while household demand is often higher in the morning and evening. Battery storage helps bridge this gap by storing surplus solar generation for later use.
For this installation, the battery system enables the homeowner to increase self-consumption, reduce electricity imported from the grid and support load shifting by storing energy for use at more cost-effective times.
When paired with a smart energy tariff, such as Octopus Intelligent Go, Agile or Flux, the customer can further optimise energy costs by charging the battery during off-peak periods and using stored energy when electricity prices are higher.
Products and Technologies Used
Principal technologies used across the solar PV and battery storage installation.

Alternergy’s Role
Alternergy supplied Sunhome with an integrated Sungrow solution combining solar panels, hybrid inverter technology, battery storage and EV charging.
Using a single manufacturer ecosystem simplified installation, commissioning and system management, while helping ensure compatibility across the main components.
Alternergy’s Role
Alternergy supplied Sunhome with an integrated Sungrow solution combining solar panels, hybrid inverter technology, battery storage and EV charging.
Project Outcomes
The project information forecasts energy-bill savings of around £100 per month, subject to household consumption, weather conditions, tariff selection and export behaviour.Battery storage can also support time-of-use tariffs by shifting electricity use towards lower-cost periods.
Real-time monitoring helps the homeowner understand how electricity is being generated, stored and consumed across the property.
Greater use of renewable electricity generated at the property can help reduce the household's overall carbon impact.
The system provides a foundation for future household electrification, including potential EV charging or heat-pump integration.
Project Significance
What This Means for Sunhome
It provides a practical reference project for homeowners looking to combine renewable generation with greater control over when and how electricity is used.
