Thunder Energy Services: plug-in solar kits for compact UK homes

Thunder Energy Services Ltd is a company registered in England and Wales that sells plug-in solar energy kits designed for spaces where traditional solar PV installation does not fit. Its catalogue is built around two product families: the lightweight Storm systems, intended for balconies, railings and facades, and the rigid Bolt systems, aimed at gardens, sheds, flat roofs and rear extensions.

The company states that approximately half of UK households cannot install rooftop solar panels, so it has developed compact, UK-compliant solutions for that segment of homes.

Storm and Bolt: two approaches to generating energy without building work

Storm kits use flexible panels and are presented as an option for balconies and facades, with railing mounting. Bolt kits use high-performance TOPCon solar panels and app monitoring, and are aimed at gardens, sheds, outbuildings, flat roofs and rear extensions.

Both families are offered in 360 W, 460 W, 710 W and 920 W configurations, and the company states that going from box to generating electricity takes about ten minutes, with no complex permits. Bolt systems are listed on the ENA Connect Direct register for UK plug-in solar and connect via a standard UK three-pin plug, subject to applicable installation requirements.

Services beyond kit sales

Alongside its product catalogue, Thunder Energy Services offers solar installation, PV design and SAP optimisation services. The company also provides users with a savings calculator that estimates annual energy production and financial savings based on postcode, chosen system, installation orientation and current cost per kWh. Calculations are based on solar radiation data from the European Commission's PVGIS database and assume a 14% system loss with a vertical tilt of 90°.

Customer profile and proposition

The company targets tenants, flat owners and homeowners looking to reduce their energy bills and carbon footprint without undertaking a conventional solar installation. Thunder Energy Services states that its business was born from its founders' personal experience of space limitations, high upfront costs and the lack of accessible solutions in the traditional solar market.
