Frequently Asked Questions
Solar panels are made up of photovoltaic (PV) cells that convert sunlight directly into direct current (DC) electricity. This DC electricity flows from the panels into a solar inverter, which converts it into alternating current (AC) electricity — the same type your home or business already uses for appliances, lighting, and equipment. During the day, your solar panels generate electricity that powers your property directly. Any surplus is either stored in a battery (hybrid system), exported to the WAPDA grid (on-grid system), or both. At night or when solar generation is insufficient, you draw power from your batteries or from the WAPDA grid as normal.
Pakistan is one of the most solar-favorable countries in the world. Most of Pakistan including Wazirabad, Islamabad, Lahore, Faisalabad, Multan, and Karachi receives between 4.5 and 6 peak sun hours per day on average across the year. This is significantly higher than Europe (2–4 hours) where solar is already the fastest-growing energy source. Pakistan's sunny climate means a correctly sized solar system generates substantial electricity year-round with peak generation in the long summer days of May through August, precisely when air conditioner loads are highest and your electricity bill is most painful.
Yes solar panels generate electricity from daylight, not direct sunlight. On overcast and cloudy days, panels produce approximately 10 to 25% of their peak output depending on cloud density. In Pakistan, even during the cooler, shorter days of December and January, generation remains meaningful typically 60–75% of peak summer output. Modern monocrystalline panels also perform better in cold, clear winter days than in extreme summer heat, since PV cell efficiency actually improves slightly at lower temperatures. Your system is designed using annual average generation data, not peak summer figures so winter performance is already factored into your savings projections.
It depends on your system type. On-grid solar systems automatically shut down during load-shedding as a NEPRA safety requirement this protects WAPDA lineworkers who may be working on the grid. If you want power during load-shedding, you need a hybrid solar system with battery storage. Hybrid systems detect grid failure instantly and switch to battery power in under 10 milliseconds keeping your lights, fans, ACs, and appliances running without any manual intervention throughout the entire outage. This is the single most important factor driving Pakistan's rapid adoption of hybrid solar over on-grid systems.
Yes solar panels are completely safe when installed by certified professionals. AEDB-certified solar installations use engineered mounting structures that distribute panel weight evenly across roof beams without penetrating the waterproofing layer. Properly installed solar panels actually protect the roof surface beneath them from UV degradation, rain impact, and thermal cycling extending the life of the underlying roof in many cases. Our installation team conducts a roof structural assessment before every installation to confirm load capacity and specify the correct mounting system for your roof type — concrete slab, steel truss, clay tile, or metal sheet.
In Pakistan's average solar conditions, 1 kW of solar panels generates approximately 120 to 150 kWh of electricity per month or roughly 1,440 to 1,800 kWh per year. This figure varies by location (Multan and Karachi average slightly more than Islamabad and Peshawar due to higher irradiance), roof orientation (south-facing roofs in Pakistan maximize output), and tilt angle (25–30° is optimal for most of Pakistan). Use our solar calculator above to get a specific generation estimate for your system size and location.
Solar system costs in Pakistan depend on system type, size, panel brand tier, and whether battery storage is included. Here are current approximate ranges for fully installed, complete systems including panels, inverter, batteries (where applicable), mounting structure, wiring, and NEPRA net metering registration:
- 3 kW On-Grid: Rs. 350,000 – Rs. 500,000
- 5 kW On-Grid: Rs. 550,000 – Rs. 800,000
- 6 kW Hybrid (with lithium batteries): Rs. 750,000 – Rs. 1,100,000
- 8 kW Hybrid: Rs. 950,000 – Rs. 1,400,000
- 10 kW Hybrid: Rs. 1,200,000 – Rs. 1,800,000
- 20 kW Commercial: Rs. 2,200,000 – Rs. 3,200,000
- 50 kW Commercial: Rs. 5,000,000 – Rs. 7,500,000
- 100 kW Industrial: Rs. 8,000,000 – Rs. 12,000,000

Most residential customers reduce their monthly WAPDA bill by 60% to 80%. On a Rs. 25,000 monthly bill, that means savings of Rs. 15,000 to Rs. 20,000 per month Rs. 180,000 to Rs. 240,000 per year. Commercial and industrial customers with higher consumption and three-phase connections often achieve 70–80% bill reductions. With NEPRA prosumer registration, net billing credits for surplus exported units can reduce some customers' bills to under Rs. 3,000 per month regardless of total consumption. Actual savings depend on your system size, consumption pattern, and DISCO tariff slab.
With current electricity tariff rates in Pakistan, most solar systems pay back their full capital cost through electricity savings within the following timeframes:
- Residential On-Grid: 3 to 4.5 years
- Residential Hybrid: 4 to 5.5 years
- Commercial Solar: 2.5 to 4 years
- Industrial Solar: 2.5 to 3.5 years
After full payback, your system continues generating electricity at near-zero cost for the remaining 20+ years of its operational life representing a cumulative return many times the original investment. With Pakistan's electricity tariffs rising 15–25% annually, the real payback period in practice is often shorter than these estimates suggest, because your savings grow in value every year while your system cost stays fixed.
Solar is currently one of the strongest financial investments available to Pakistani homeowners, businesses, and industries. Three factors make it particularly compelling right now: First, WAPDA electricity tariffs are at historic highs and rising the cost of not having solar increases every year. Second, solar panel and equipment prices have fallen by over 60% in the past five years globally making the same system significantly more affordable today than it was in 2020. Third, Pakistan's high solar irradiance means systems here generate more electricity per rupee invested than almost anywhere in Europe or North America. Residential payback of 3–5 years on a 25-year asset is a return that virtually no other investment class in Pakistan can match with this level of certainty and predictability.
Pakistan's federal government has previously offered various solar incentives including sales tax exemptions on imported solar panels and equipment under SRO notifications, and net metering regulations that enabled solar prosumers to earn credits for exported electricity. Consult the latest Federal Board of Revenue (FBR) notifications and NEPRA circulars for current incentive status, as these policies change periodically. Some provincial governments have also run subsidized solar programs for agricultural tube wells and rural electrification.
