Humbie Mains Farm

Can solar cut grid reliance and earn income too?

Since installing a ground-mounted solar system, Humbie Mains Farm has significantly reduced its reliance on the national grid. It has also secured a contract to sell its surplus power back, so sunny days now bring in income.

Why did Humbie Farm look to Solar?

Humbie Mains is a traditional arable farm in West Lothian, run by landowner Andrew Bayne-Jardine. Its energy demand is substantial, from the daily work of the farm to a household that runs a ground source heat pump, an AGA and two electric vehicles.

Andrew had thought about solar for some time. As electricity prices climbed and showed no sign of easing, he approached Forster Group in 2023.

"Solar was something we’d been thinking about for a while, but the spiralling costs of electricity were the final push. I couldn’t see prices falling anytime soon and solar offered a practical, sustainable solution."

-Andrew Bayne-Jardine, Landowner

The Forster Solution

Forster Group drew on decades of experience in agricultural and commercial installations to design a 72.72kWp ground-mounted solar PV system around Humbie Mains’ daily energy needs. The design also allows for the farm’s future growth.

Surplus power is sold back to the grid under a contract Andrew has secured.

"We’ve only had a couple of small electricity bills during winter. I used to worry about our energy bills constantly - now I have another reason to celebrate when the sun shines on Humbie Farm. It’s effortless income."

-Andrew Bayne-Jardine, Landowner

What has solar delivered so far?

The results have exceeded expectations. The system is outperforming its projections and has significantly reduced the farm’s reliance on the national grid. It comfortably covers the household’s demand through spring and summer, and surplus credit helps offset the lower output over winter.

Andrew has also secured a contract to export surplus power. Given the size of the installation, Humbie Mains has the potential to earn up to £12,000 a year from selling electricity back to the grid.
