Portable, modular solar that mounts directly on fences – no ground‑footprint, no scaffolding, anywhere you need it.
Whether you're running a construction site, an outdoor event, or simply need power at a rural farm, getting connected used to mean hiring noisy, unreliable generators or paying for complex permanent electrical installations.
Solar on Site changes that. Born out of our own frustration with failing diesel generators, we've built a truly portable, modular solar unit that gives you immediate power exactly where you need it.
Modular and ready to go instantly. No heavy machinery, no groundworks, and no scaffolding required. Perfect for any scale.
The entire base system breaks down to transport securely in a standard transit van.
Plugs directly into any electrical system. Use it completely off-grid or as a hybrid system.
No fumes, no fuel spills, and no noise complaints. Perfect for ecologically sensitive areas, late-night events, and strict noise-restricted urban zones.
The only portable solar system engineered to mount directly onto temporary site fences, domestic garden boundaries, and standard hoarding.
Designed to reliably power everything from a single garden office to a full-scale construction site.
Easily add extra battery packs or daisy-chain units for higher capacity loads.
The entire base unit breaks down to fit comfortably in a standard transit van.
Built exactly for your specific site requirements by our engineering team.
Calculate how long our systems can power your site on a single charge (assuming zero solar input).
Time until battery depletion. Solar input will extend this significantly.
Now that you know what it can do, here is where it belongs. A flexible solution designed for the most demanding environments.
Reliable power for site offices, welfare units, and CCTV. Perfect for noise-restricted zones where diesel generators are prohibited. Modular scalability means it grows with your site.
Silent, emission-free power for weddings, corporate events, and showjumping in areas of natural beauty. Provide premium off-grid experiences without the drone of a diesel engine.
Create free electricity for personal home use. Easily mount a compact 3-panel system to your back garden fencing and plug it directly into your home. No massive footprint required.
Dependable off-grid electricity for farms, smallholdings, and remote locations with no mains access. Keep critical systems running cleanly and efficiently.
It started with a broken diesel generator on a freezing November morning. We were losing hours of daylight, burning cash on fuel, and dealing with the noise and fumes that constantly disrupted site communication.
We didn't just want a "green" alternative. We wanted a system that was actually better than diesel—silent, instantly deployable, and completely self-sufficient. When we couldn't find one that survived the reality of a UK construction site, we built it ourselves.
We aren't a catalogue company. We're an engineering firm building rugged solutions born on construction sites, but designed for anyone who needs reliable, scalable power.
Tell us about your site, your power needs, and your timeline.
We assess your exact power requirements and recommend the right configuration.
We bring it in the van and have you operational in under 20 minutes.
Your site is powered. Silent, clean, and completely self-sufficient.
Yes. Our panels generate power even in overcast conditions — they don't need direct sunlight. On cloudy UK days you'll see reduced output, but the battery system stores energy so you have continuous power regardless of weather. The system is designed and tested for British conditions.
Under 20 minutes from van to live power. The panels mount directly onto your existing site fencing or hoarding — no ground works, no scaffolding, no specialist tools. We handle the entire setup for you.
A 5kW system comfortably handles CCTV masts, LED site lighting, tool charging stations, and a welfare cabin simultaneously. For heavier loads, we can daisy-chain additional battery packs or deploy multiple units. Use our Capacity Estimator above to model your exact requirements.
We handle everything. Delivery, installation, testing, and handover are all done by the founders personally. You don't need to lift a finger — just tell us where you need power and we'll sort the rest.
We currently serve Kent, Surrey, and Sussex. We're based in Kent and can typically be on-site within 24–48 hours of your enquiry. If you're outside these areas, get in touch — we may still be able to help.
Absolutely. The system is fully modular. You can add additional battery packs to extend autonomy, or deploy extra panel arrays to increase generation. We design every installation with future expansion in mind.
Tell us about your site and we'll come back to you with a tailored portable power solution — usually within 24 hours.
