Benefits of Prolectric off-grid power generators
Lower Fuel Use and Running Costs
A solar-first approach significantly reduces generator runtime, lowering fuel consumption and refuelling requirements. Fewer deliveries and interruptions mean smoother day-to-day operations and reduced servicing requirements, even on extended deployments.
Quieter, Cleaner Working Environments
Solar solutions significantly reduce noise and eliminate onsite emissions, improving conditions around welfare areas, compounds and public-facing boundaries. The result is a safer, more comfortable environment for both site teams and neighbouring communities.
Smarter Control, Fewer Call-Outs
Connected remote monitoring and intelligent energy management deliver real-time visibility of performance and usage. Scheduling, alerts and reporting reduce unnecessary site visits and make it easier to manage multiple locations – giving you full control from anywhere.
More Predictable Power
Solar generation and battery storage support peak demand and reduce generator runtime, improving stability during low-load operation and across full day-night cycles. The result is consistent, reliable power, with backup available when required.
Clear Reporting for Your Business Case
Generate clear, shareable insights on fuel, cost and carbon savings for procurement, sustainability leads and stakeholders. Compare performance across sites and projects using trial data, enabling a confident transition from trial to full fleet rollout.

Project Manager, Kier Transportation | Highways Major Projects
Prolectric have been an outstanding supplier in recent months. From point-of-sale to product support, there is nothing I can fault. Their products save our customers a fortune and reduce carbon emissions across sites. A key thing about Prolectric is you’re not left on your own – support is truly unmatched. With special thanks to Nick and Mitch for all their assistance, we now run a small fleet since buying the first unit.
Laura Tudhope
Plant Manager, Askam Civil Engineering
As an established leading temporary electrical contractor for events, television, and festivals for 20 years, we were looking to offer our clients a greener option for their temporary power requirements. We loved the idea of Prolectric’s Solar Hybrid Generator, the ProPower. We are more than happy with both the service and the product that Prolectric offer and are excited to see our clients benefit from such an innovative product.
Jerry Stevens
Director, Templine Services
Since the start of the 52-week hire period in July, the ProPower Solar Hybrid Generator engine only ran for around 16% of the time. This substantial reduction in generator usage translated to massive fuel savings and significantly lowered overall emissions on the site. The overall site was powered by solar and battery alone, showcasing the effectiveness of Prolectric’s products in providing sustainable and reliable energy solutions.
Gary Quinton
Project Manager, CLM Construction
We installed our first ProPower in June 2022, and the backup generator didn’t run once in the first month. Customers are seeing savings of up to £6.5k per month per unit on fuel alone. We can map their load profile and turn things on and off remotely so it’s all running optimally. It’s very efficient compared to traditional diesel generators. Also, there’s a lot less servicing required because the generator runs less frequently.

Explore our off-grid power solutions
Our off-grid power solutions provide a more efficient way to keep sites running without reliance on grid upgrades or ongoing refuelling. By combining solar generation, battery storage, intelligent energy management and backup power, our systems reduce disruption, improve control and deliver reliable power for demanding site environments.
Key benefits at a glance
Adaptable power for changing site demand
Match your setup to the load profile, operating hours and site layout. Scale and adapt as programmes evolve – without over-specifying from day one.
Reduced downtime
A solar-first hybrid approach reduces reliance on continuous maintenance and refuelling. The result is a more stable setup, longer deployments and fewer interruptions to site operations.
A cleaner alternative to traditional generators
Improve air quality and reduce noise in critical areas such as compounds, welfare zones and public-facing boundaries – while taking a commercially viable step towards lower-impact power.
Simplified deployment in remote or constrained locations
Where site access is limited, grid capacity is restricted or timelines are uncertain, our solutions integrate remote monitoring and control to reduce reliance on external works – keeping your projects moving with less disruption.
