Off-grid solar

Off-grid systems have no grid to fall back on, so the design has to be right through the shortest winter day and the longest cloudy week. We size solar, batteries and inverters for how you actually live.

Who it's for

  • Rural and remote properties where a grid connection is impractical or costly
  • Sheds, workshops and outbuildings away from the main supply
  • Owners who want independence from the grid

Why us

Sized for winter
We design around your lowest-sun months and your real usage, not around summer averages.
High-end batteries and inverters
Off-grid systems work their batteries every single day, so we only use high-end storage and inverter brands.
Designed for the future
We plan capacity so you can add panels or storage as your needs grow.

Questions

Do I need a generator with an off-grid system?

Many off-grid properties keep a backup generator for extended poor weather. We'll discuss whether one suits your site and usage when we design your system.

How do you size an off-grid system?

From your appliances and daily usage, your location's winter sunlight and how many days of autonomy you want. We'll talk this through with you before quoting.
