Energia Solar Libre
Use solar energy efficiently

We design, install and maintain solar systems with battery storage. The grid stays as backup.

Area for the array60 m²
Peak output9,8 kW
60 m²
  • 18545 W panels
  • 13 700kWh per year
  • 4,8 tCO₂ not released

Estimated at 1,400 kWh per 1 kW a year and 0.35 kg CO₂ per 1 kWh. Exact figures follow the roof survey.

The house stops being a source of bills, cutting dependence on electricity suppliers by 100%

We come to the site, survey the roof, calculate output month by month, fit the panels and the battery storage, connect it all and then maintain what we have installed. One contract and one responsible party for the whole life of the system.

A year of warranty servicing included.

  • 14 000kWhOwn output of a 10 kW system over a year
  • 4,9t CO₂Kept out of the atmosphere in the same year
  • 25yearsLinear performance warranty on the panels

Calculated at 1,400 kWh per 1 kW a year and 0.35 kg CO₂ per 1 kWh.

A day in figures: system output and household demandDuring the day output exceeds demand and the surplus goes to the battery storage. In the evening the house runs on stored energy.0610141822surplus to storageevening on stored energyhousehold demandoutput
A typical day for a system with battery storage: output peaks around midday, demand peaks in the evening, and the battery storage carries one across to the other.

Why people trust us

  • One company for the whole cycle

    Site survey, design, supply, installation, connection and servicing under a single contract. No need to line up a supplier, an electrician and a service company and then work out which of them is at fault.

  • We name the equipment

    545 W panels rated Tier 1 by Bloomberg NEF, Deye hybrid inverters, LiFePO₄ battery storage. Models and specifications are visible before signing and can be checked independently.

  • Survey first, estimate after

    We do not give prices over the phone. First we measure the area, pitch and azimuth of the roof, then look at shading and the consumer unit. The estimate is free.

  • Mounting built for the weather

    Ballasted and rail systems to suit your roof type. Panels withstand 3,800 Pa wind and 5,400 Pa snow load.

  • Servicing after handover

    Output monitoring, scheduled panel cleaning, diagnostics of the inverter and the battery storage. A system should work for all 25 years, not just the first season.

The three parts of a solar system

The panel captures light, the inverter turns it into household voltage, the battery storage carries the day over to the evening.

545 W panel

Monocrystalline with half-cut cells: fewer losses to shading and resistance, and a lower temperature coefficient.

  • Tier 1 in the Bloomberg NEF classification
  • 3,800 Pa wind and 5,400 Pa snow load
  • TÜV testing: salt mist, ammonia, dust, fire

Deye hybrid inverter

Runs on-grid and off-grid alike. It decides where the energy goes: to the house, to the battery storage or to the grid.

  • Efficiency up to 97.6%, conversion losses kept minimal
  • Two independent MPPT inputs: slopes of different orientation do not interfere
  • IP65 enclosure, protection against reverse polarity, overload and earth fault

Single-phase and three-phase models, several inverters can run in parallel

LiFePO₄ battery storage

Lithium iron phosphate, the calmest of the lithium chemistries: no cobalt, no lead or acid, holding a steady voltage almost to the end of discharge.

  • 4,000–8,000 cycles, that is 10–15 years of daily work
  • Round-trip efficiency 90–95%: almost everything stored comes back to the house
  • Depth of discharge up to 80–90% without accelerated degradation

Capacity is added in blocks, from 5 kWh upwards as demand grows

Turnkey kits

Panels, inverter, mounting, installation, paperwork and connection – all in one contract.

  • Electric car charging
Request an estimate

The kits are a starting point, not a catalogue. For a hotel, apartments, a farm or a commercial site the system is built from the same three parts, only at a different scale. We give the price after the survey: it depends on the roof type, the cable runs and the state of the consumer unit. The estimate is free and commits you to nothing.

Request a free estimate

Tell us about the property. We will calculate the output and give you the price of the system.

  • We reply during working hours, usually the same day
  • The site survey is arranged at a time that suits you
  • No commitment until the estimate is signed
