Where Off-Grid Solar Makes Sense
If a building sits too far from the house to run mains cable easily, off-grid solar is often the tidiest way to get power to it.
Sheds, Workshops & Garages
Buildings too far from the house for mains, where you want lights, sockets and somewhere to charge tools.
Stables & Agricultural Buildings
Lighting, water heaters and fence energisers running off their own solar, away from the mains.
Garden Offices & Studios
Steady power for laptops, screens, Wi-Fi and heating in a space you work from every day.
Security Lighting & CCTV
Gates, drives and outbuildings kept lit and covered without digging a cable run across the property.

Off-Grid Solar Questions
What does off-grid solar mean?
An off-grid system generates and stores its own power on site, with panels, a battery bank and an inverter. It runs a building or vehicle on its own supply instead of the mains, which makes it the practical choice for sheds, workshops, stables and outbuildings that sit away from the house.
Do I need certification or grid paperwork for an off-grid system?
Off-grid systems sit outside the grid paperwork, so the install stays straightforward. We wire and fuse everything to a safe standard and label it clearly so you know what is what.
How do you decide what size system I need?
We start with what you want to power and how often. From there we size the panels and battery to match, so you are not paying for oversized kit you will not use. If you are not sure, tell us the building and the main things you want to run and we will work it out with you.
Can I add more later?
Yes. We set systems up so panels or battery capacity can be added later. If your usage grows, a garden office turns into a full working space, or you add more tools to a workshop, the system can grow with it.
Which areas do you cover?
We cover Exeter and roughly a 30-mile radius across Devon, including Exmouth, Topsham, Crediton, Tiverton, Honiton, Sidmouth and the surrounding villages. If you are just outside that, get in touch and we will let you know.
