Features
Lightweight Solar for Small Spaces: Two ultra-light 178W flexible TOPCon solar panels, each weighing just 3.5 kg. Their slim full-black design makes Storm 360W ideal for balconies, railings, fences, sheds and other locations where conventional rigid panels may be impractical.
Simple Plug-In Solar: Connect the panels to the Hoymiles microinverter, then plug the system directly into a standard UK socket using the supplied fused 3-pin AC cable. No dedicated solar circuit or complicated electrical installation required.
Smart Energy Monitoring: Built-in Wi-Fi and Bluetooth connect Storm to the S-Miles Home app, giving you live system monitoring from your phone. The Hoymiles microinverter delivers up to 96.7% peak efficiency and 99.8% MPPT efficiency.
Built for Outdoor Use: Storm panels are TÜV certified and tested to IEC 61215 and IEC 61730 standards, with IP67 protection and a Class C fire rating. Their flexible construction combines durability with a lightweight 3.5 kg design.
Quick DIY Setup: Everything you need is included for a straightforward installation. Secure the panels, connect them to the microinverter and plug the system into your home. No roof work required.
UK-Compliant Plug-In Solar: Storm 360W is built for the UK's plug-in solar framework, combining compliant solar panels, a G98-listed Hoymiles microinverter and a fused UK 3-pin connection for a complete home plug-in solar system.
Flexible Cable Options: A 5m AC connection cable is supplied as standard, with an optional single-piece 10m AC cable available where extra reach is needed. No additional extension lead or adaptor is required.

FAQs
Is the Storm 360W a plug-in solar system?
Yes. Storm 360W is a complete UK plug-in solar kit designed to generate electricity directly into your home through a standard UK 3-pin socket. The system combines two flexible solar panels with a Hoymiles microinverter and a fused UK AC connection cable.
Do I need an electrician to install Storm 360W?
No. Storm 360W is designed for straightforward DIY installation without a dedicated solar circuit. Secure the panels in a suitable location, connect them to the microinverter using the supplied cables, then plug the system into a suitable household socket. The UK's plug-in solar framework specifically enables compliant solar-only systems to connect without requiring a separate electrical circuit or routine electrician installation.
Where can I install the Storm solar panels?
The lightweight flexible panels are ideal for balconies, railings, fences, sheds, garden offices and other suitable outdoor surfaces. Each panel weighs just 3.5 kg, making Storm particularly useful where conventional rigid solar panels would be too heavy or difficult to mount.
How do I monitor my solar generation?
The Hoymiles microinverter has built-in Wi-Fi and Bluetooth and works with the S-Miles Home app. You can view system performance and solar generation from your phone, either locally through Bluetooth or remotely through Wi-Fi.
Do I need to notify my Distribution Network Operator (DNO)?
Yes. Plug-in solar systems remain subject to the applicable G98 grid connection requirements. Thunder provides guidance to help you with the DNO notification process. The UK plug-in solar specification is specifically designed to operate alongside the updated G98 framework.
What cable length is included?
Storm 360W includes a 5m AC connection cable as standard. If your socket is further away, an optional 10m single-piece AC connection cable is available. This replaces the standard 5m cable, so no separate extension lead or adaptor is required.
Can I add battery storage later?
Yes. Storm can be upgraded with compatible battery storage if you want to store surplus solar energy for later use. Alternatively, the Storm Plus range includes the Hoymiles HiBattery 1920 AC as part of the complete system. Battery-equipped systems follow a different connection route from solar-only plug-in systems because batteries are not included within the UK's solar-only plug-in framework.

Annual consumption: 2,700 kWh (Ofgem typical medium household). Winter 60% / Summer 40%.
System: 4 x Storm 178W flexible solar panels (TopCon monocrystalline), total 0.71 kWp. Microinverter: Hoymiles HMS-800W-2T (800 VA, 2 MPPT, 96.7% peak efficiency).
Orientation: Modelled at 90-degree vertical mounting (typical for fence or balcony railing). This is a conservative estimate. Tilting panels to a more favourable angle will increase generation.
Year 1 generation: 525 kWh (estimated for London, based on typical balcony/fence mounting).
Panel degradation: 2% in year 1, 0.7%/year thereafter (conservative estimate for flexible ETFE panels).
Seasonal generation split: Winter 28% / Summer 72% (Thames region profile).
Self-consumption rate: 100% year-round. System output is well below household demand, so all generation is consumed on-site.
Electricity tariff: 30 p/kWh peak (average smart time-of-use daytime rate), 7 p/kWh off-peak (overnight rate), 3% annual inflation.
Battery: Hoymiles HiBattery 1920 AC (HB-1920-AC-SV), 1.92 kWh usable capacity, LiFePO4 cells, AC-coupled, 87% round-trip efficiency, IP66, 6,000+ cycle life, 10-year warranty.
Battery arbitrage: Off-peak grid charging at overnight rates, peak discharge during daytime. 365 days per year at full capacity (1.92 kWh). Solar generation is consumed directly by the household and does not charge the battery, leaving full battery capacity available for grid arbitrage year-round. Battery operates at 800W maximum output, sufficient to offset household base load during peak hours.
87% round-trip efficiency.
Battery arbitrage savings assume the customer is on a smart time-of-use tariff with off-peak overnight rates. Actual returns may be higher or lower than projected
depending on tariff availability and usage patterns. All figures are estimates based on the assumptions above and should not be considered as guaranteed
returns.
