Can I Use Plug-In Solar on an Allotment?
The allotment shed with a solar panel on the roof and a battery inside is one of the most practical small solar applications around. No mains power to the plot, no standing charge, just useful generation when the sun is out. None of the domestic plug-in solar regulations apply to it.
What the allotment setup actually is
An allotment installation is off-grid. Allotments do not have mains electricity supplied to individual plots. You run entirely from solar and battery storage: panels charge the battery, battery powers lighting, phone charging, a radio, power tools — whatever you need. No grid connection, no G98 notification, no SI 2026/848 rules.
The right setup is a 12V DC system with a quality MPPT charge controller, a leisure battery, and either 12V DC appliances or a small inverter for 240V AC use. A 200W panel and a 100Ah leisure battery gives reliable lighting and small appliance use for several days without sun. A 400W panel and a second battery handles power tools and more demanding use.
Do I need permission from the allotment committee?
Possibly. Allotments are typically council-owned or association-managed with their own site rules. Some councils actively encourage solar on allotment sheds. Some have rules about external structures and require written permission. Check your allotment tenancy agreement and site rules before installing. Most committees are supportive — solar is a practical, reversible installation with no permanent damage to the structure — but do not assume permission is implied. Planning permission from the local planning authority is not normally required for panels on an allotment shed under permitted development rules.
What kit works for an allotment
A simple setup: 200W panel (around £70), 20A MPPT controller (around £30), 100Ah 12V leisure battery (around £90), and a 300W pure sine wave inverter (around £40) if you need 240V AC. Total under £250. Handles lighting, phone charging, radio, and occasional short power tool use across most of the year without any grid connection.
The EcoFlow STREAM is overkill for most allotment uses and expensive for what is essentially a shed power supply. A conventional MPPT controller and leisure battery is the right tool here.
