Solar projects and energy audits, engineered in Lebanon
We design and build solar PV and battery storage that work with EDL and your generator, and we audit buildings and factories to find where energy is lost.
- 2010Founded in Zalka, Lebanon, as an energy services company
- 1.5MWpMoulin D’Or solar project, on rooftops and carports
- 1.3MWpSolar hybrid plant at Wooden Bakery HQ, with SMA fuel save control
- 14.8GWh/yrMeasured energy savings across 18 projects
- 150+Hotels, factories and businesses we have worked with
- 2,000+Residential hybrid solar systems
Solar projects
Solar PV and storage designed around your load, your EDL hours and your generator. We are designer and main contractor, from the site survey to commissioning and maintenance.
Hybrid solar with storage
PV, hybrid inverters and lithium batteries that take over from EDL and the generator.
High-voltage storage
Battery racks with 50 kW hybrid inverters in parallel for commercial and industrial sites.
Solar with generators
PV running in parallel with diesel generators, with fuel save control.
On-grid and off-grid plants
Grid-tied PV for daytime loads, and standalone systems where there is no reliable grid.
Homes and villas
More than 2,000 residential hybrid systems with lithium or OPzV batteries.
Structures and carports
Steel PV structures for roofs, hillsides and carports, designed and checked by our engineers.
Where your power comes from, hour by hour
A hybrid system adds two sources you control, the sun by day and batteries at night, so the generator becomes the backup.
- Solar
- Battery
- EDL grid
- Diesel generator
Illustration only. The real split depends on your EDL hours, your consumption and the PV and battery sizes we design for your site.

Energy consultancy
Our certified energy managers measure how a hotel, factory or building uses energy, rank the measures by cost and savings, install them, and verify the savings afterwards.
How an investment-grade audit runs
Facility examination
Site inspection, operating schedules and up to 36 months of bills.
Inventory of systems
Lighting, HVAC, motors, pumps, boilers, generators. First energy balance in kW and kWh.
Measurement campaign
Data loggers on the loads that matter: power factor, harmonics, temperatures, lighting levels.
Baseline
Base-year consumption, with end uses reconciled to within 5%.
Energy conservation measures
Cost, savings, life expectancy, risks and emission reductions for each one.
Measurement and verification plan
How each saving will be measured, agreed before implementation.
Implementation and follow-up
Installation, verification of results, training and metering.
Measured annual savings
MWh saved per year after the efficiency measures and solar plants were installed
Total 14,810 MWh a year across 18 projects
Savings identified in our latest energy audits
Yearly savings and costs as reported to each client. Payback is the project cost divided by the yearly saving.
| Client | Measures proposed | Savings per year | Cost | Payback |

| Total | 5 audits | $354,234 | $1,328,004 | 3.7 yr |
Buildings in design
We work with the architect and engineers while energy decisions are still cheap to change.
- Pre-design: energy goals and design guidelines
- Schematic design: daylighting, simulation, life-cycle cost
- Design development: materials, systems, cost-benefit
Measures we implement
We install what the audit recommends, so the savings in the report are the savings you get.
- LED lighting retrofits with lighting simulations
- Heat recovery from generators, boilers and processes
- Energy management and metering: kWh, BTU, water
- Solar PV sized on the reduced, measured load
Measurement and verification
Our Certified Measurement and Verification Professional prepares the M&V plan with each audit and verifies the results. Baselines, formulas and assumptions are documented so your own engineers can repeat the calculation.

About GPG
Green Power Generation SARL is a Lebanese engineering company based in Zalka. We started in 2010 auditing hotels and factories, and today we design and build solar and storage projects as designer and main contractor.
A plant sized on a measured, reduced load is smaller and better used than one sized on a guess. That is why every project starts from bills and measurements, and why our support continues after handover.
