If your evenings suddenly feel darker in 2026, you are not imagining it. The federal government has brought back **scheduled evening load shedding of up to 2.25 hours per day**, timed inside the peak-demand window of **5PM to 1AM**. Announced by the Power Division in April 2026 as a "Peak Relief Strategy," the plan is meant to shave peak load and stop tariffs from climbing by roughly Rs 3 per unit.

For most families, that outage lands at the worst possible time — when everyone is home, dinner is cooking, and the fans need to run. And here is the hard truth many solar owners are discovering: **a grid-tied solar system alone cannot cover evening load shedding.** If you want power during those 5PM–1AM cuts, you need a hybrid-plus-battery setup. Let's break down exactly why, with real 2026 PKR figures.

Why the Evening Load Shedding Timing Hurts Solar Owners

Solar panels only make electricity when the sun is shining. Peak production runs roughly from 10AM to 3PM. By 5PM — when the new load shedding window opens — your panels are already winding down, and by sunset they produce nothing at all.

So the exact hours you now lose grid power (5PM–1AM) are the exact hours your panels are least productive. This mismatch is the core problem, and no amount of extra panels fixes it. You are generating energy in the afternoon but needing it at night.

Why Grid-Tied Solar Goes Dark During Outages

Here is the part that shocks new owners. A standard **on-grid (grid-tied) solar system shuts off completely the moment the grid fails** — even at high noon with blazing sun.

This is not a fault; it is a safety feature called **anti-islanding**. To protect linemen who may be repairing the network, grid-tied inverters are designed to stop exporting the instant they detect a grid outage. No grid, no output.

During evening load shedding, a grid-tied solar system is as useless as having no solar at all — because it legally must switch off when the grid drops.

So even if you spent lakhs on panels last year, when WAPDA cuts your feeder at 6PM, your grid-tied inverter trips and your home runs on nothing. That is why grid-tied solar alone cannot cover night outages.

Net Billing 2026 Makes Self-Consumption Even More Important

There is a second reason to rethink your setup in 2026. On **9 February 2026, NEPRA replaced net metering with net billing** under the new Prosumer Regulations.

  • **Old net metering:** 1 unit exported = 1 unit offset from your bill (same value both ways).
  • **New net billing:** your exported units are bought back at a NEPRA-set rate of roughly **Rs 10–11 per unit**, while you still buy grid units at the full retail tariff (often Rs 40–70+ per unit for many slabs).

Consumers with valid net metering agreements before 9 February 2026 keep their old rates until their agreement expires. But for everyone installing now, the maths has flipped: **exporting cheap and importing expensive is a losing trade.** The smart move is to store your daytime surplus in a battery and use it yourself at night — precisely when load shedding hits. Battery storage has gone from "nice to have" to the heart of a sensible solar investment.

How a Hybrid + Battery Setup Solves Evening Outages

A **hybrid solar system** combines panels, a hybrid inverter, and a battery bank. It does three things a grid-tied system cannot:

1. **Stores surplus daytime energy** in a lithium battery instead of exporting it for Rs 11. 2. **Keeps working during outages** — the hybrid inverter seamlessly switches to battery power when the grid drops. 3. **Runs your evening load** (lights, fans, fridge, Wi-Fi, a TV, and even an inverter AC on larger systems) straight through the 5PM–1AM window.

Because the 2.25-hour cut sits inside a predictable window, you can size a battery specifically for it — you don't need to power the whole house all night, just the essentials through the scheduled outage.

What It Costs in Pakistan (2026 PKR Figures)

Here is a realistic comparison based on current 2026 market rates. Lithium (LiFePO4) storage now runs roughly **Rs 40,000–55,000 per kWh**.

| System type | Typical 2026 price (PKR) | Covers 5PM–1AM outage? | |---|---|---| | 5kW grid-tied (no battery) | 700,000 – 900,000 | No — shuts off during cuts | | 5kW hybrid + ~5kWh lithium | 771,000 – 1,093,000 | Yes — essentials | | 8kW hybrid + ~10kWh lithium | 1,204,000 – 1,713,000 | Yes — most of the home | | 15kW hybrid + lithium storage | ~2,200,000 | Yes — full home + AC |

A single **10kWh lithium battery** (around Rs 400,000–550,000) is enough to run a typical family's evening essentials — a few fans, LED lights, a refrigerator, routers and phone charging — comfortably through a 2.25-hour cut, with margin to spare on nights when the outage runs longer or repeats.

### A practical tip from our installations

Set your hybrid inverter to **prioritise battery + solar during the 5PM–1AM window and recharge from cheap daytime solar**, not the grid. Program the battery to reserve at least 20% state-of-charge by 5PM. This way you enter every evening outage with a full tank, ride it out silently (no diesel generator, no fumes), and still bank surplus units for the next day. Pairing this with efficient DC inverter fans and appliances can stretch a 10kWh battery well past the scheduled cut.

Frequently Asked Questions

**Can I add a battery to my existing grid-tied solar system?** Sometimes, but not always cheaply. If your inverter is a pure grid-tied (string) model, you'll likely need to add a battery-ready hybrid inverter or an AC-coupled retrofit unit. It is usually more cost-effective to plan a hybrid system from the start. Ask your installer for a retrofit assessment before buying.

**How big a battery do I need for the 5PM–1AM load shedding?** For most homes, a 5–10kWh lithium battery covers evening essentials — lights, fans, fridge, Wi-Fi, and charging — through a 2.25-hour cut. If you want to run an inverter AC as well, look at 10kWh or more paired with an 8kW+ hybrid inverter.

**Is solar still worth it in 2026 after net metering was replaced by net billing?** Yes — but the value now comes from self-consumption, not export. With buyback at only Rs 10–11 per unit versus retail tariffs several times higher, storing and using your own power (especially during evening load shedding) delivers far better savings than exporting to the grid.

**Will a hybrid system power my whole house during an outage?** It depends on sizing. A 5kW hybrid handles essential circuits; an 8–15kW hybrid with a larger battery can run most of the home, including an air conditioner. Tell your installer which appliances must stay on during the 5PM–1AM window so the system is sized correctly.

The Bottom Line

Evening load shedding from **5PM to 1AM is back in 2026**, and it targets the exact hours grid-tied solar cannot help you. Between anti-islanding shutoffs and the new net billing rules that reward self-consumption over export, the case for batteries has never been stronger. A **hybrid solar system with lithium storage** keeps your family powered, quiet, and independent through every scheduled cut.
