Solar has become one of the most popular investments in Pakistan — by 2024 the country was importing more solar panels than any other in the world. But in 2026 the rules changed. If you are planning a system for your home, office or factory, the way you design it now matters more than ever.
What changed in 2026: net metering to net billing
In February 2026, the National Electric Power Regulatory Authority (NEPRA) notified the Prosumer Regulations 2026, moving new solar users from net metering to net billing:
- Net metering (old): each exported unit offset an imported unit almost one-for-one — the grid acted like a free battery.
- Net billing (new): exported units are bought at a lower buyback rate linked to the national average energy purchase price, while you still buy grid electricity at the full retail tariff.
Following an amendment, consumers whose net metering agreements were signed before 9 February 2026 keep their existing terms until those agreements expire. The new rules apply to new applications.
Reported buyback rates in 2026 vary between roughly Rs 8 and Rs 13 per unit, and policy may change again. Always confirm the current rate and process with your distribution company (DISCO) or NEPRA's official notifications.
Why self-consumption now matters most
Under net billing, a unit of solar power you use yourself saves you the full retail tariff, while a unit you export earns only the much lower buyback rate. The economics have shifted:
- Size the system to your daytime use, not to the largest system your roof can hold.
- Shift heavy loads to daylight hours where possible — pumps, washing, cooling and production processes.
- Consider storage, so surplus daytime power can be used in the evening rather than sold cheaply.
On-grid, hybrid and off-grid compared
| System | How it works | Backup in outages | Best for |
|---|---|---|---|
| On-grid | Panels and a grid-tied inverter; no batteries | No — shuts down when the grid fails | Businesses with high daytime use and reliable supply |
| Hybrid | Panels, hybrid inverter and batteries, connected to the grid | Yes — batteries cover outages and evenings | Homes and businesses facing load-shedding |
| Off-grid | Panels, inverter and batteries with no grid connection | Fully independent | Remote sites, farms and areas without a reliable grid |
On-grid
The lowest-cost option, with the fastest payback when most of your consumption happens during the day — offices, schools, shops and factories running a day shift.
Hybrid
The most balanced choice for most households now. Batteries store daytime solar for the evening and keep essential loads running during load-shedding, which reduces reliance on exports.
Off-grid
Ideal where grid power is unavailable or unreliable — agricultural tube wells, remote sites and rural communities. Battery capacity must be designed carefully around overnight demand.
Is solar still worth it? How to judge payback
For most homes and businesses, solar remains worthwhile — but payback now depends far more on how the system is used than on exports. When evaluating a proposal, look at:
- Your grid tariff — the higher the rate you pay per unit, the more every self-consumed solar unit saves.
- Your self-consumption share — the proportion of solar generation you use directly rather than export.
- Battery cost versus value — storage raises upfront cost but shifts cheap daytime energy into expensive evening hours and covers outages.
- Outage costs — for businesses, the cost of lost production or generator fuel during load-shedding is often the strongest reason to choose hybrid.
Be cautious of proposals that calculate savings using old one-for-one net metering assumptions. Ask the installer to show savings based on current net billing rules and your real consumption pattern.
Solar for commercial and industrial sites
Businesses usually have a natural advantage under net billing: most of their consumption happens during daylight. Before sizing a commercial system, consider:
- Load profile — a factory running a day shift can use almost all of its solar output directly.
- Roof structure — confirm that the roof can carry the panel and mounting load, especially on older sheds and pre-engineered buildings.
- Critical loads — identify equipment that must keep running during outages and size storage for those loads only.
- Monitoring — remote monitoring helps spot underperformance quickly across larger systems.
Choosing quality components
- Panels: Tier-1 mono-crystalline PERC or N-type bifacial modules with clear manufacturer warranties.
- Inverters: correctly sized for your load, with monitoring and surge protection.
- Batteries: lithium-ion (LiFePO4) offers longer life and deeper discharge than conventional batteries, at a higher upfront cost.
- Mounting: galvanised steel or aluminium structures rated for local wind loads.
- Protection: DC and AC breakers, surge protection and proper earthing — often skipped to cut costs, but essential for safety.
Choosing an installer and maintaining your system
If you plan to connect to the grid under net billing, use an installer certified by the Alternative Energy Development Board (AEDB) and ask them to handle the application with your distribution company. Beyond certification, check that the installer provides product warranty documents, a written system design and after-sales support.
Once installed, simple maintenance keeps output high:
- Clean panels regularly — dust is a major cause of lost generation in Pakistan, especially in dry months.
- Watch your monitoring app — a sudden drop in output usually means soiling, shading or a fault.
- Check connections and breakers periodically, and keep inverters in a shaded, ventilated position.
- Inspect mounting structures after storms for loose fixings or corrosion.
How to size your system in 5 steps
- Collect 12 months of electricity bills to understand your consumption pattern.
- Estimate how much of that consumption happens during daylight hours.
- List the essential loads you need running during outages.
- Choose the system type: on-grid, hybrid or off-grid.
- Get a site survey for roof space, shading, orientation and structure.
Solar is still worthwhile in Pakistan, but the best systems are now designed around using your own power. Right-size the array, consider storage, and never compromise on protection equipment.

Frequently asked questions
Is net metering still available in Pakistan in 2026?
Not for new users. Under NEPRA's Prosumer Regulations 2026, new solar users moved to net billing. Consumers whose net metering agreements were signed before 9 February 2026 keep their existing terms until their agreements expire.
What is the solar buyback rate under net billing?
Exported units are bought at a rate linked to the national average energy purchase price — widely reported at roughly Rs 8 to Rs 13 per unit in 2026, far below the retail tariff. Confirm the current rate with your distribution company before signing.
Is solar still worth it in Pakistan after net billing?
For most homes and businesses, yes — but the savings now come mainly from using solar power yourself rather than exporting it. Systems should be sized to your daytime consumption.
Which is better: on-grid or hybrid solar?
On-grid has the lowest cost but no backup during outages. Hybrid adds batteries, so you can store daytime solar for the evening and keep power during load-shedding — which matters more now that exports earn less.
