Solar panels off grid

At Volta Energy, our solar panels run fully off grid. That means sustainable power wherever your project is, with no fixed connection to the existing energy grid required. Ideal for construction, telecom, and renewables sites in remote or hard-to-reach locations, where getting a grid connection would mean months of delay, or isn't possible at all.

Easy to move

Our off-grid solar panels are built to be relocated as your project moves. The Volta 15 and Volta 45 are towable as a trailer behind a pickup truck, so you can move the system between sites without a separate transport. The Volta 6 sits on a pallet chassis and is easily repositioned with a forklift, while the Volta 120, our heavy-duty model, is delivered by truck for large-scale construction and infra projects. Whatever the site, from a construction yard to a remote telecom mast to a solar or wind farm under development, there's a model that fits.

Cost-saving and sustainable in one

Because our solar panels run off grid, they generate most of their own power on-site: quietly, and with a clean fuel backup that only activates when solar and battery genuinely can't keep up. That's good for the planet, and for your budget. Depending on the model, our systems use up to 81% less fuel than a diesel generator.

Power always and everywhere

An off-grid solar system from Volta Energy combines solar panels, a battery, and a backup, the smart buffer for peak loads. During the day, the panels generate energy, even in overcast weather, and store it in the battery. That means you have power in the evening and overnight too. As a backup for sustained high demand or extended low-sun periods, each system includes a clean HVO100 or methanol generator, which only kicks in when it's genuinely needed.

Frequently Asked Questions about Solar panels off grid

  • What does off grid mean for solar panels?
    Off grid means the solar panel system generates and stores its own power on-site, without needing a connection to the existing electricity grid.
  • How do off-grid solar panels provide power at night or in bad weather?
    The solar panels charge a battery during the day, even in overcast conditions, which then supplies power in the evening and overnight. If demand exceeds what the battery and solar can deliver, a clean HVO100 or methanol backup generator activates automatically.
  • How much fuel do off-grid solar panels save compared to a diesel generator?
    Depending on the model, an off-grid Volta system uses up to 81% less fuel than a diesel generator, typically saving around €200 per week.
  • Can off-grid solar panels be used on remote construction or telecom sites?
    Yes. Off-grid solar panels are well suited to construction sites, infrastructure projects, telecom cell tower locations, and renewables projects in locations where a grid connection isn't available or would take months to arrange.
  • Do off-grid solar panels need a diesel generator as backup?
    No. The backup generator runs on HVO100 biofuel or methanol instead of diesel, and only activates when solar and battery power genuinely can't meet demand.
