How Beyond Green Solar Delivered a 950 kW Solar System for Carrefour
A 950 kW solar system is now powering a Carrefour site in Pakistan, designed and installed end to end by Beyond Green Solar. The plant supplies a large share of the store’s daytime electricity, cutting energy costs for a business that runs lights, chillers and air conditioning for long hours every day.
For large retailers, electricity is one of the biggest operating costs after rent and staff. This case study explains why commercial solar makes sense for supermarkets, how our team delivered a near-megawatt project, and what other businesses can expect from a similar system.
Why Retailers in Pakistan Are Switching to Commercial Solar
Grid power in Pakistan is expensive and unpredictable, and large commercial users are moving to their own generation. For CY2026, NEPRA set the national average tariff at Rs 33.38 per kWh, with business groups pushing back on the cross-subsidies loaded onto non-domestic consumers (Profit).
The shift is now big enough to worry policymakers. A June 2026 report said the government had to draft a new tariff policy because so many large power users are moving to solar and other self-generation (BOL News).
Supermarkets are a natural fit for solar. Their heaviest loads, such as cooling, refrigeration and lighting, peak during the day when panels produce the most. A 950 kW solar system locks in a large share of that daytime power at a fixed cost for 25 years.
About Carrefour Pakistan
Carrefour is operated in Pakistan by Majid Al Futtaim, which has run hypermarkets in the country since 2009, first as Hyperstar and later under the Carrefour brand (RetailDetail). Its stores serve shoppers in Karachi, Lahore and Islamabad.
A modern hypermarket is energy-intensive. Cold rooms, open chillers, freezers, bakery ovens, escalators and HVAC run from opening to closing, seven days a week. That steady daytime load means almost every unit a solar plant produces is used on site, which gives the fastest return on investment.
950 kW Solar System: Project Overview
The Carrefour plant is a 950 kW grid-tied system sized to cover the store’s daytime base load. Confirm the items marked “to confirm” before publishing.
- System size: 950 kW (0.95 MWp)
- System type: On-grid commercial solar (to confirm)
- Mounting: Rooftop / parking carport (to confirm)
- Solar panels: Tier-1 mono PERC or N-type modules, quantity to confirm
- Inverters: Commercial string inverters, quantity to confirm
- Monitoring: Remote, real-time generation monitoring
- Location: City and store to confirm
- Commissioned: Month and year to confirm
- EPC contractor: Beyond Green Solar Solutions
For scale: a 950 kW solar system typically uses around 1,550 to 1,650 panels in the 580 to 620 W range and roughly 4,800 to 5,700 square metres of shade-free roof or parking area.
How We Delivered the Project
Beyond Green Solar ran the project as a full EPC contract, so the client had one accountable team from survey to handover. The store stayed open to customers throughout.
- Energy audit and site survey. Our engineers reviewed the store’s electricity bills and hourly load profile, then surveyed the roof, parking area and shading.
- System design. We modelled generation with local irradiance data from the Global Solar Atlas and sized the array to match daytime cooling and lighting demand.
- Structural and electrical engineering. Mounting structures were designed for local wind loads, and cabling, protection and earthing were specified for a busy public building.
- Installation. Our crews worked in phases and outside peak shopping hours, keeping customer areas safe and unaffected.
- Testing and commissioning. Every string and inverter was tested before the system was synchronised with the store’s supply.
- Monitoring and after-sales support. The client tracks output in real time, and our team provides cleaning schedules, maintenance and performance checks.
Expected Generation and Savings
In Pakistan’s major cities, a well-designed 950 kW solar system typically produces about 1.38 to 1.57 million units (kWh) a year. These are typical estimates, not the measured output of this plant.
- Annual generation: 1.38 to 1.57 million kWh
- Average daily generation: 3,800 to 4,300 kWh
- Annual savings at Rs 35 to 45 per unit: Rs 48 to 70 million
- Typical payback period: Around 2.5 to 4 years
- Panel performance life: 25+ years
Actual savings depend on the store’s tariff, self-consumption share and net metering terms. Replace these figures with the site’s measured data once a few months of monitoring are available: real numbers make a case study far more credible.
Environmental Impact and Brand Value
At a typical grid emission factor of about 0.45 tonnes of CO2 per MWh, a 950 kW plant avoids an estimated 620 to 710 tonnes of CO2 a year. Over 25 years, that is more than 15,000 tonnes.
For a consumer brand, visible solar panels also send a message to shoppers. Clean on-site power supports sustainability reporting, and a rooftop or carport array shows customers the brand is investing in a greener Pakistan.
Is Commercial Solar Right for Your Business?
The Carrefour project shows that near-megawatt solar works well for supermarkets, malls, hospitals and warehouses with steady daytime demand. Before you invest, check these points:
- Daytime load. Businesses with heavy cooling and lighting use solar power directly, which gives the fastest payback.
- Usable space. Plan roughly 5,000 to 6,000 square metres of roof or parking area per megawatt. Solar carports turn parking lots into power plants and give shoppers shade.
- Roof condition. Check that the roof can carry the panels for 25 years before installation.
- Net metering and regulations. NEPRA’s 2026 prosumer rules change how exported units are settled, so sizing should favour self-consumption (The News).
- Storage. Stores with evening peaks or frequent outages can add battery storage to extend solar use.
- A verified EPC partner. Choose an installer with large commercial references, in-house engineers and after-sales support.

Frequently Asked Questions
How many units does a 950 kW solar system produce per day? In Pakistan’s main cities, a 950 kW solar system typically produces about 3,800 to 4,300 units per day on average, or 1.38 to 1.57 million units a year.
How much space does a 950 kW solar plant need? Around 4,800 to 5,700 square metres of shade-free roof or parking area, depending on panel wattage and layout.
Can solar run a supermarket’s chillers and air conditioning? Yes, during daylight hours. Grid power or battery storage covers evenings and nights.
What is the payback period of commercial solar in Pakistan? At current commercial tariffs, a well-sized system commonly pays back in about 2.5 to 4 years.
Does Beyond Green Solar install large commercial systems? Yes. The 950 kW Carrefour project is one example of our commercial and industrial work across Pakistan.
