Garden solar

Generate clean energy from your garden with no roof needed

Thunder’s garden solar panels can be mounted on fences, sheds, garage walls or any sun-facing solid surface. A simple and flexible way to produce renewable power at home without rooftop access. Lightweight, efficient and available with optional battery storage for greater energy independence.

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.

What a garden solar system can power

  • 640 kWh

    per year

    A 710W garden solar system can generate up to 640 kWh annually in typical UK conditions

  • 1,000+

    laundry cycles

    Enough to power more than 1,000 washing machine cycles a year

  • 53,000

    phone charges

    Roughly 53,000 full smartphone charges from clean solar energy

  • 9,000 hrs

    of TV time

    Enough electricity to run a standard LED TV for around 9,000 hours

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.

How our garden solar systems work

01

Capture daylight

Solar panels capture daylight from your garden and produce clean DC energy.

02

Convert to AC

The microinverter converts DC energy into safe and usable AC electricity.

03

Plug in

The system plugs into a standard UK socket through a fused spur.

04

Use or store

Your home uses the generated energy instantly and any surplus can feed into a battery or the grid.

Can I put solar panels in my garden?

Yes, you can install solar panels in your garden in the UK, and it is one of the easiest ways to generate clean energy without using your roof.

Garden-mounted solar systems are lightweight, flexible and designed for installation on solid surfaces such as fences, sheds, garage walls and open ground. Most garden solar installs do not require planning permission unless the system is unusually large, the property is listed, or the home is within a conservation area.

Garden solar panels installation guide

1

Find the sunniest vertical spot

Choose the brightest section of your fence, wall or balcony where panels receive the most daylight throughout the day.

2

Mount panels high enough from the ground

Position your panels at a safe height to avoid accidental contact, shading or splashing from rainwater.

3

Final electrical connection

Connect the microinverter and plug the system into your fused spur or designated outdoor socket following UK safety standards.

4

Check straps and hooks periodically

Inspect the mounting hardware every few months to ensure everything remains tight, secure and weather-safe.
