David Stinton: Reducing Home Energy Costs
A 10-panel rooftop system with a Fronius 3.6kW inverter, installed in just two days.

Ken McConaghy: Reducing Reliance on the Grid
Adding SOLARWATT battery storage to an existing solar system to use more of his own energy.
David McMullan: Lowering Farm Costs
The brief
David McMullan wanted to reduce his farm’s dependency on the grid and lower its electricity costs.
As a forward-thinking farmer, he saw the benefits of solar for a more sustainable, cost-effective operation, but wasn’t sure which setup would suit his needs best. That’s when he turned to us for guidance.
We supplied the equipment and Solar Power NI handled the installation, tailoring a solution to David’s exact requirements.
Our solution
Installation and commissioning took three days. The goal was to let the farm generate its own power and minimise the cost of running machinery and other electrical equipment.

Client benefits
The solar array covers a substantial portion of the farm’s energy needs, particularly during peak sunlight, significantly reducing electricity bills.
Energy spend is now more predictable and stable, helping with financial planning and budgeting for the farm.

David Stinton: Reducing Home Energy Costs
The brief
David Stinton wanted to reduce his household electricity costs while lowering his carbon footprint.
He understood the advantages of solar but wasn’t sure which equipment would suit his home best.
We supplied the materials and Solar Power NI handled the installation. Together we created a bespoke solution for his home.
Our solution
Solar Power NI completed installation and commissioning in just two days, giving David a system that generates enough electricity to reduce his reliance on the grid.

Client benefits
David saw an immediate impact. The system generates a significant portion of the electricity his home needs, particularly during peak sunlight hours.
His electricity bills are lower and his household’s carbon footprint is reduced, supporting the more sustainable lifestyle he was after.

Ken McConaghy: Reducing Reliance on the Grid
The brief
After enjoying the benefits of the solar panels we supplied a few years ago, Ken McConaghy wanted to make his home even more energy efficient.
He wanted to be less reliant on the grid, especially during the darker months. We took the time to understand his needs and advised adding battery storage to his setup.
Our solution
We supplied the equipment and Solar Power NI installed and commissioned the battery storage, so Ken can store excess solar energy for later use. This gives him greater control over his energy use and improves the overall efficiency of his system.
Client benefits
Ken can now store excess energy produced during peak sunlight hours and use it when needed, at night or when sunlight is low.
This has further reduced his dependency on grid power, helping him make the most of his solar investment and lower his energy bills even further.
