Green aggregate

Looking for a green aggregate? Meet the Volta: a solar-powered 3-in-1 mobile energy system that supplies energy on site without the noise, fumes, or emissions of a diesel aggregate. Built for construction sites, telecom infrastructure, renewables projects, traffic control systems, and mobile camera security setups, wherever reliable power needs to show up without a fixed grid connection.

How does a solar-powered green aggregate work?

A Volta combines three elements: solar panels, a battery, and a backup. The solar panels generate energy during the day, which is converted and stored in the battery for later use. That means you have power in the evening and at night, plus a buffer for moments of peak demand. For sustained high demand or extended low-sun periods, a clean backup generator running on HVO100 biofuel or methanol activates automatically, instead of the diesel engine you'd find in a standard aggregate.

Cost-saving

Choosing a solar-powered 3-in-1 mobile energy system over a diesel aggregate cuts more than nitrogen and CO₂ emissions, it cuts costs too. Diesel and HVO100 both add up fast as consumption rises, while solar energy itself stays free, even at large-scale use. On average, a Volta uses 60% less fuel than a comparable diesel aggregate.

Easy to move

A generator should do more than supply electricity, it should be easy to work with. Every Volta comes with 1- or 3-phase connections and is built to be relocated as your project progress. The Volta 15 and Volta 45 are towable as a trailer, so you can get reliable power even to hard-to-reach locations, while the Volta 6 sits on a pallet chassis for easy repositioning with a forklift, and the Volta 120 is delivered by truck for large-scale sites.

Frequently Asked Questions about green aggregates

  • What is a green aggregate?
    A green aggregate is a power system that generates electricity mainly from solar energy and battery storage, rather than a constantly running diesel or petrol engine.
  • How much fuel does a green aggregate save compared to diesel?
    On average, a solar-powered system like the Volta uses 60% less fuel than a comparable diesel aggregate.
  • Does a green aggregate still use fuel?
    Only occasionally. A clean backup generator running on HVO100 biofuel or methanol activates automatically during sustained high demand or extended low-sun periods, and stays off the rest of the time.
  • What's included when you rent a green aggregate from Volta Energy?
    Every rental includes delivery, fuel management, maintenance, and remote monitoring in one fixed price, so there's no separate contract to arrange.
  • What size green aggregate do I need for my project?
    It depends on the load. The Volta 2F and Volta 6 suit lighter, continuous loads like camera security or traffic control systems, while the Volta 45 and Volta 120 are built for larger construction sites with heavier equipment.
