With power outages, rising electricity tariffs, and the promise of energy independence, many homes in Pakistan are considering off-grid solar systems. But what does that mean in terms of cost, benefits, and trade-offs?
Here’s a deep dive (2025 data) into what you might expect.
What is “Off-Grid Solar”
Off-grid = the system works independently of the national grid. Batteries store electricity, an inverter converts solar output into usable power, and panels generate energy. You rely fully on your own setup (plus sun & battery capacity), so you need a system sized well for your needs (appliances, hours of use, backup time).
Cost Breakdown
The total cost depends on a few big factors:
- System size (in kW)
- Battery storage (capacity, type: lead-acid, AGM, Lithium etc.)
- Quality and brand of panels/inverter/balance of system components
- Installation complexity, site location, labor costs
Here are some data points to give you a sense of ranges (all in Pakistani Rupees, PKR):
| System Size | Approx Cost (Off-Grid, Full Back-up) | What It Might Power / Use Case |
|---|---|---|
| 3 kW | ~ PKR 400,000‒600,000 brightsolar.pk+2approachpakistan.com+2 | Small house (2-3 rooms), basic lighting, fans, maybe small ACs for limited hours, a few lights, fridge etc. Backup for nights & cloudy days with moderate battery. |
| 5 kW | ~ PKR 1,100,000‒1,600,000 for full off-grid with lithium battery storage. Solar Required | Medium house, more loads, possibly multiple ACs, more lights/appliances, more hours of backup. |
| 7 kW | ~ PKR 800,000‒1,300,000 depending on how much battery you want. approachpakistan.com+2approachpakistan.com+2 | Larger homes, business-use, heavier load. |
| 10 kW | ~ PKR 2,200,000‒3,200,000 for full off-grid (with large battery bank) Solar Required | Big house or small commercial usages, enough energy to run many appliances & long backup, possibly several hours at night. |
| Cost per kW | ~ PKR 120,000–150,000+ per kW (off-grid) when batteries are included. Price Lab+2approachpakistan.com+2 | Helps you do rough sizing: e.g. a 5 kW system ~ 5×150,000 = ~PKR 750,000 just for a baseline off-grid setup. |
What Drives the Cost
These components make up most of your investment:
- Solar Panels – quality, wattage, brand matter. 40-45 % of the cost often. approachpakistan.com
- Batteries / Energy Storage – could be 30-40 % or more, especially for full backup. Lithium types cost more but last longer. AGM/lead-acid are cheaper but heavier, shorter lives. approachpakistan.com+2approachpakistan.com+2
- Inverter(s) & Charge Controller – converting DC to AC, managing battery charging etc. Better quality = more cost. Solar Required+1
- Mounting Structure, Wiring, Protection, Accessories – safety, wiring, supports for panels, Fuses/Breakers etc. Often 5-15 %. Solar Required
- Installation & Labor – getting everything mounted, wired up, setup. If roof structure is complex, or site far, costs go up.
Benefits vs Trade-Offs
Here are what you get vs what you pay or give up:
Benefits:
- True energy independence: no impact from load-shedding or unstable grid supply.
- Potential long-term savings: after “payback period,” your energy cost per kWh is much lower.
- Environmental: clean energy, lower carbon footprint.
- Possible increase in property value, resilience.
Trade-Offs / Costs:
- High upfront cost, especially for battery storage.
- Maintenance & replacements: battery life is limited; need to replace every 5-10 years (or even less if poor quality). Panels last longer but even they degrade.
- Need good sizing & demand management: if you overshoot usage (lots of AC, heating loads etc.), batteries may not cover, or you might undersize.
- Weather dependence: less sun in winter/clouds means lower yield; need enough storage to cover.
- Space: for panels, batteries, inverter etc.
What to Watch For to Get the Best Deal
- Battery type: Lithium vs AGM vs lead-acid. Even if lithium is more expensive, lower maintenance, higher efficiency, more cycles.
- Reputable brands & warranties on panels, inverters, batteries.
- Installer certifications: Certified/experienced vendors, proper design.
- Correct sizing: More capacity than you think you need is better because backup hours matter.
- Quality of materials: Wiring, mounts, protection gear should be safe & durable.
- Local incentives, import duties, government policy: Since many components are imported, taxes/supply chain affect cost heavily.
Is It “Worth It”?
It often is, especially if:
- You live in an area with frequent blackouts or no grid power.
- Electricity tariffs are high (so saving per kWh is big).
- You stay in the property for many years (to recover investment).
- You can afford the upfront cost, or get favorable financing.
For many households, payback periods for off-grid systems might be 4-8 years (depending on size, usage, cost of electricity avoided). After that, you’re getting “free” electricity (minus some maintenance).
Example: 5-kW Off-Grid System in Pakistan
To make this concrete:
| Component | Approx Cost |
|---|---|
| Panels (5 kW) | PKR ~200,000-300,000 (depending on panel brand & efficiency) Solar Required |
| Inverter (off-grid or hybrid) | ~ PKR 150,000-250,000 for good quality 5 kW inverter Solar Required |
| Battery bank (10-15 kWh, lithium) | ~ PKR 250,000-400,000 Solar Required+1 |
| Mounting & Structure, Wiring, Safety | ~ PKR 80,000-120,000 Solar Required |
| Installation & Labor | ~ PKR 70,000-120,000 Solar Required |
Total estimate: ~PKR 1,100,000-1,600,000 for full off-grid, with decent backup. If you go with cheaper batteries or shorter backup, you might bring costs lower.
Future Trends & What to Expect
- Battery prices (especially lithium) are gradually falling globally. As supply improves, local costs may decrease.
- More competition among solar panel & inverter brands in Pakistan → more options, better prices.
- Government policies (taxes, import duties, subsidies) will continue to affect cost heavily.
- Solar＋hybrid systems are becoming more popular: you remain grid-connected, use solar/daylight, battery for outages; this reduces battery size and cost compared to full off‐grid, but gives a lot of benefit.
