It doesn’t always make financial sense for a dairy farm to go solar. After all, much of their energy use takes place before the sun comes up.

But when Chris at Bagot Dairy contacted us, we took the time to analyse his energy usage and figure out a solution that would save him money. Instead of creating a solar system that fed excess solar back to the grid, we fed that power to hot water, plate cooling and other loads.

This dramatically cut down the dairy’s night-time usage, providing the greatest possible return on investment.

We also designed the solar array to face north, but also east and west, to spread the solar generation from sunrise through to sunset.

Because we used quality products, the system is performing above expectations, and is set to reap huge rewards for Chris over the years, and reduce his overheads in a challenging industry.
