New — Solar power as a service

Silent, clean power — anywhere you need it.

Trailer-mounted solar generators that replace the diesel set on construction sites, festivals, farms and field bases. We deliver, deploy and monitor the unit remotely — you just plug in.

Who it's for

One solution — four kinds of sites.

Wherever you need power without waiting for grid connection or relying on diesel — a mobile solar generator fits.

Construction sites
Construction

Construction sites

Power site offices, lighting, hand tools and battery chargers without noise or fuel costs. Ideal for early-stage sites before grid connection is in place.

  • No midnight refuelling stops
  • Silent mode — works in residential zones
  • Fits CSR commitments and green tenders
Concerts, festivals, productions
Events

Concerts, festivals, productions

Stage sound, lighting, catering and equipment charging — without a diesel growl behind the stage and no fume cloud over the crowd.

  • Silent recordings and streams — zero engine noise
  • Low-carbon event with documented metrics
  • Flexible placement — wherever it suits the layout
Remote and off-grid sites
Off-grid

Remote and off-grid sites

Farms, cabins, hunting lodges, vineyards, research camps and seasonal sites where running a grid line is expensive or impossible.

  • Seasonal rental with zero capital cost
  • Replaces a petrol or diesel generator
  • Remote monitoring — you can see what's happening
Industrial and emergency response
Emergency

Industrial and emergency response

Field bases, mobile command posts, industrial maintenance, medical tents, repair and disaster-response crews — anywhere reliable power is mission-critical.

  • Fast delivery and on-site commissioning in hours
  • On-board battery — keeps running through the night
  • Hybrid option with a generator for peak loads
Comparison

Diesel generator or mobile solar plant?

Both produce power on site. The difference is in the noise, the running cost and what they leave behind.

The classic choice

Diesel generator

  • ✕Steady 70–95 dB drone — uncomfortable for everyone nearby
  • ✕Exhaust fumes and the smell of fuel
  • ✕Fuel — logistics, cost and theft risk
  • ✕Frequent oil and filter changes, regular service intervals
  • ✕No real-time view of consumption or runtime
Recommended

Mobile solar plant

  • ✓Silent operation — practically inaudible
  • ✓Zero on-site emissions — no smell, no smoke
  • ✓No fuel, no tank logistics
  • ✓Minimal maintenance — cleaning and inspections
  • ✓Remote monitoring 24/7 — on phone or laptop
What you rent

Three types of mobile solar systems.

Depending on your load and timeline, we configure a unit that delivers exactly the energy you need — no oversized hardware.

Solar generator on a trailer

A compact mobile plant with an integrated panel array, battery and inverter. Ready to run within minutes of delivery — just position, unfold and plug in.

  • 120/230 V outlets and three-phase output on request
  • Lithium battery — power through the night
  • Under 3,500 kg — towable with a light commercial vehicle

Solar array trailer

A larger panel array for sites with higher loads. Feeds a primary or hybrid inverter and pairs with a generator or central battery bank.

  • Up to 5 kW peak / ~30 kWh per day
  • Standalone twin-axle trailer
  • Easy connection to additional battery storage

Solar–diesel hybrid

Solar panels and a battery paired with a small diesel generator for peak loads or extended overcast periods. Up to 70% less fuel than a pure diesel setup.

  • Automatic switchover sun ⇄ generator
  • Silent at night — diesel stays off
  • Good fit for long sites with critical loads
How it works

5 steps from inquiry to live.

You call in the morning — your site has power tomorrow. We handle everything in between.

  1. 01

    Short consultation

    You share the site, the load, the timeline and the location. We recommend a configuration and quote.

  2. 02

    Trailer delivery

    We tow the unit to your site. Anywhere in Bulgaria — typically within 24–48 hours.

  3. 03

    Deployment & start-up

    We position the trailer, unfold the panel array, connect the outputs and verify all protections. Live in minutes.

  4. 04

    Monitoring 24/7

    We watch the plant remotely — production, battery state, alarms. You see the same data on your phone.

  5. 05

    Pick-up

    At the end of the rental we pick the unit up with no extra effort from you. The site is left exactly as we found it.

Frequently asked questions

Everything about mobile solar rental.

How long can I rent a unit for?
From a single day up to many months. Standard terms are daily, weekly and monthly rental — with better rates for longer commitments. For long-term rental (over 6 months) we offer a custom plan.
How much does it cost?
Pricing depends on unit type, capacity and term. Indicatively: daily rental from ~€130, weekly from €620 and monthly from €1,800 — delivery in Northern Bulgaria included. A precise offer follows a short site consultation.
What is included in the rental?
Delivery and pick-up, on-site setup, cabling and standard outlets, 24/7 remote monitoring, phone support and a full hardware warranty. If a unit fails on our side, we replace it at no extra charge.
Is there a deposit or insurance?
Yes. A refundable deposit is required and is returned after pick-up if the equipment is in good condition. We recommend adding the unit to your site insurance — we help with the documents.
How much energy does the unit produce per day?
A standard 5 kW peak solar array delivers around 25–35 kWh per day in summer and 8–15 kWh in winter under clear skies. The integrated battery lets you use that energy at night too.
Can it run an air conditioner, welder or motor?
Yes — the units are sized for surge loads. For sites with heavy inductive loads or long working cycles we recommend the solar–diesel hybrid configuration to guarantee reliability.
Do you deliver across Bulgaria?
Yes. Our base is in Silistra and we serve the whole country. For remote locations the lead time may be 12–24 hours longer. Transport is part of the offer — no hidden charges.
What happens during long overcast spells?
The battery covers a 1–2 day buffer. For longer overcast periods or critical loads we recommend the hybrid setup, where a small diesel generator kicks in automatically — still using up to 70% less fuel than a pure diesel plant.
