This project involved a full solar and storage installation using an in-roof mounting system, giving the finished result a clean, integrated appearance.
27 dual-glass all-black panels were installed using a GSE in-roof system, paired with a SigEnergy hybrid inverter, two batteries and a smart energy gateway. The result is a system that generates, stores and manages electricity, reducing grid reliance and keeping energy costs down throughout the year.
System highlights
-
- 27 x Solfit 425W dual-glass all-black panels (GSE in-roof system)
- 1 x SigEnergy Sigenstor 8kW hybrid inverter
- 2 x SigEnergy 8.76kWh batteries (17.52kWh total storage)
- 1 x SigEnergy HomePro gateway
What does this mean?
On a good summer’s day, the system can generate between 45 and 55kWH of electricity. In spring and autumn, that typically falls to around 20 – 35kWH, and in winter, to between 5 and 10kWh. With 17.52kWh of battery storage, any surplus generation during the day is saved for use in the evening, rather than exported unused.
For a typical household, that translates to self-sufficiency levels of up to 95% in the summer, 50-70% in spring and autumn and 20-40% in the winter. Even at the low end of that range, the combination of stored solar and smart tariffs means the system is working to reduce costs all year round.
Smart energy management
The SigEnergy HomePro gateway takes the system a step further by acting as a smart energy hub. It provides seamless backup power during any grid outage, with automatic changeover that requires no manual intervention. It also enables the batteries to be charged overnight on off-peak tariffs, so lower-cost electricity can be stored and used during peak hours when grid prices are higher. This is particularly valuable during winter months, ensuring the batteries are put to full use even when solar generation is limited.
Solar installations for domestic properties are zero-rated for VAT. With panel prices at their lowest for years and rising grid electricity costs, we are seeing an increase in demand across Oxfordshire and the Cotswolds.
