10 Solar Myths in Pakistan, Answered Honestly

Short answer

Most solar disappointments in Pakistan start with a myth, not a bad product: that panels work at night, that a bigger panel or a bigger system is always better, that any battery fits any inverter, that panels need no cleaning, or that net metering still pays the old rate. None of these is true. Below, each myth gets a short, honest answer and a link to the guide that explains it fully.

We are an engineering company, so we have no interest in selling you a system built on a misunderstanding. A system that matches your load, roof and the current rules will serve you well for many years; one built on a myth will not.

Myth 1: "Night solar panels produce power after dark"

The truth: No solar panel produces useful power at night. Panels need light, and output falls to zero after sunset. Adverts for "night solar panels" are usually an ordinary panel sold with a battery, where the battery supplies the night power. Panels do still work in fog, cloud and smog, but at reduced output.

If you need power at night, you need either the grid or a battery charged during the day. Read do solar panels work at night, in fog and in smog?

Myth 2: "More watts per panel is always better"

The truth: A higher-watt panel is physically larger, not magically stronger. A 700 W panel makes more power than a 615 W panel mainly because it has more cells and more area. Per square foot of roof, the difference comes from cell efficiency, not the watt label.

Very large panels can also be harder to lift onto a roof, may not fit a small or oddly shaped roof, and must suit the inverter's current limits. The right panel is the one that fills your roof sensibly and matches the inverter. See 600 to 750 watt solar panels and which roofs suit them, and, for the extreme case, does a 1000 watt solar panel exist?

Myth 3: "Any battery will work with any inverter"

The truth: Batteries and inverters must match in voltage, type and communication. A 48 V lithium battery cannot be connected to an inverter built for a high-voltage battery stack, and the reverse is also true. Even at the same voltage, many lithium batteries must "talk" to the inverter, and the inverter maker publishes a compatibility list.

Choosing the battery and inverter as a set avoids an expensive mismatch. Read high-voltage vs low-voltage solar batteries and 24 V vs 48 V lithium battery.

Myth 4: "Solar panels need no cleaning; rain does the job"

The truth: In much of Punjab, rain is too rare in the dry months to keep panels clean. Dust, smog film, bird droppings and, near factories, lint or cement dust build up and block light. A dirty array quietly produces less every day.

Regular gentle cleaning with clean water and a soft brush, in the early morning or evening, is part of owning solar here. Never use a pressure washer or harsh chemicals. Our guide how often should you clean solar panels in dusty Punjab? sets out a routine.

Myth 5: "Net metering still pays the old rate"

The truth: Since 9 February 2026, new rooftop solar connections come under NEPRA's net billing rules, not the old one-for-one net metering. Imported units are billed at your normal tariff, and exported units are credited at a much lower rate, reported at about Rs 10-11 per unit when the rules were notified. People who already had a net metering agreement, or applied by 8 February 2026, keep the old terms until their agreement expires.

So a seller who calculates your savings at the old one-for-one rate is using outdated arithmetic. Read our net metering and net billing guide.

Myth 6: "A bigger system always pays back faster"

The truth: Under net billing, the value of solar comes mainly from units you use yourself, because each one saves a full-tariff grid unit. Extra panels whose output mostly goes to export earn only the export rate, so they pay back more slowly. A bigger system is not wrong, but it should be sized to your daytime load first, with a battery considered for the evening.

Read sizing your solar system under net billing, and learn how to estimate payback honestly in solar energy cost and payback in Pakistan. We do not promise payback periods; we show you how to work them out from your own bills.

Myth 7: "All quotations for the same kW are the same kit"

The truth: Two "10 kW" quotations can differ in almost everything except the headline: panel brand and model, inverter brand and model, battery, structure height and steel, cable size and brand, breakers, earthing and surge protection, and who does the installation. A lower price usually means something on that list has changed.

Ask every company for an itemised BOQ with brand, model, quantity and warranty for each line, and compare line by line. Our guide to comparing solar quotations gives a checklist, and how to check genuine solar panels explains how to verify serial numbers.

Myth 8: "With solar, I will have power during load-shedding"

The truth: It depends on the system. A plain on-grid inverter shuts down when the grid fails, by design, so line workers are not put at risk. That means no solar power during load-shedding, even at noon. A hybrid inverter with a battery can keep chosen loads running; some hybrids can also run from panels alone in daylight without a battery, but behaviour varies by model.

If backup matters to you, say so at the start. Read can a solar inverter work without a battery?

Myth 9: "Panels produce the most in the hottest months"

The truth: Summer brings long, bright days, but heat itself reduces panel output. Every panel loses a small percentage of power for each degree its cells rise above 25°C, and Punjab rooftops in May and June run very hot. Clear, cool, bright days are where panels perform best per hour of sun.

This is why panel choice, airflow under the panels and structure height matter. Read solar panels in Punjab summer heat.

Myth 10: "Solar panels stop working after ten years"

The truth: Good-quality panels are generally designed to keep producing for decades, losing a small share of output each year rather than failing on a set date. Inverters and batteries have shorter service lives than panels and may need replacing during the system's life.

What shortens a system's life most is poor installation: loose connectors, undersized cables, weak structures and bad earthing. See average lifespan of solar panels and our installation quality checklist.

The pattern behind the myths

Most of these myths share one root: treating solar as a single product with a single number on it. In reality, a solar system is a set of matched parts designed around your load, roof, connection and the rules in force. That is why every system we quote starts with your bills and a site survey, not a fixed package.

Our in-house engineers design each system, our own teams install it, and the quotation names every brand, model and warranty. Manufacturer warranties apply per product and are. We add a 3-year structure warranty and a 1-year service warranty under the applicable project terms. Founded in 2021, Solar Works Pakistan has served 300+ customers, including 50+ industrial clients, from about 6 kW to megawatt scale.

Frequently asked questions

Do solar panels work at night in Pakistan?

No. Panels produce no useful power after sunset. Night-time power comes from a battery charged during the day, or from the grid.

Is a 700 W solar panel better than a 615 W panel?

Not automatically. It is larger and makes more power per panel, but the right choice depends on your roof size, structure and inverter limits. Compare efficiency and fit, not just the watt label.

Can I use my old battery with a new inverter?

Only if the battery's voltage and type match the inverter and, for lithium, the two can communicate. Check the inverter's battery compatibility list before buying.

Do I still get net metering if I install solar now?

New applicants since 9 February 2026 come under net billing, where exports are credited at a lower rate than imports. Existing agreement holders keep their terms until expiry.

Will rain clean my solar panels?

Occasionally, but not reliably in Punjab's dry and dusty months. Plan for regular gentle cleaning with clean water and a soft brush.

Why is one solar quotation much cheaper than another?

Usually because the equipment, structure, cables, protection or installation differ. Ask for an itemised BOQ from each company and compare line by line.

Does an on-grid solar system work during load-shedding?

No. An on-grid inverter switches off when the grid fails, for safety. You need a hybrid inverter, usually with a battery, for backup.
