Solar PV for Grain Stores & Grain Drying

Grain stores have seasonal load profiles dominated by August-October drying. Solar matched to grain-drying peaks delivers excellent ROI — here is how KMM designs for grain operations.

Updated 6 July 20266 min readReviewed by Steve Moran

Grain stores have an unusual seasonal load: low through winter and spring, then a sharp 6-10 week peak around harvest as grain dryers run continuously. Solar PV oversized against the baseline winter load can cover the harvest peak through direct generation, with batteries time-shifting the rest. KMM has designed grain-store installs in Lincolnshire mixed-arable operations with payback inside 6 years.

What makes this sector specifically work

Roof PV
Typical 60-180kWp on grain store roof
Ground-mount supplement
20-60kWp ground-mount adjacent for harvest-peak coverage
Battery sizing
Tactical — 30-60kWh battery to time-shift solar into drying-peak windows
Grant support
Lincolnshire CC Rural Business Grant typically covers 25-30% of the ground-mount capex

Common KMM project shape for this sector

A typical grain stores & grain drying install starts with a drone-led roof survey, MPAN HH-data import, sector-specific load modelling, and a bound ROI proposal inside 5 working days. We work across the UK and the immediate surrounding counties for installs of this scale.
