Introduction
Garden Solar Panels
Garden solar panels are compact outdoor solar systems designed for UK homes that do not have suitable roof space or want a simpler and more affordable alternative to traditional rooftop solar.
Thunder's garden solar systems mount easily onto fences, sheds, garage walls or any solid sun facing surface, turning unused outdoor areas into clean energy sources. Lightweight panels and a single microinverter allow you to create your own solar setup with either a quick DIY approach or a professional installation. This flexible design makes garden solar a new and accessible way for homeowners to produce renewable electricity at home.

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: 25 p/kWh (Ofgem price cap, April 2026), 3% annual inflation assumed.
Actual returns may be higher or lower than projected depending on tariff changes and usage patterns. All figures are estimates based on the assumptions above
and should not be considered as guaranteed returns.
How Our Garden Solar Systems Work
The microinverter converts DC energy into safe and usable AC electricity.
Your home uses the generated energy instantly and any surplus can feed into a battery or the grid.
Step 1
Step 3
Solar panels capture daylight from your garden and produce clean DC energy.
Step 2
The system plugs into a standard UK socket through a fused spur.
Step 4
