Yes, panels still generate electricity on cloudy days, but at reduced output. At night, they don’t produce power – that’s where batteries or grid connection help.

Savings depend on your system size, electricity usage, and tariff rates. On average, many households save up to 50–70% on electricity bills.

Most solar panels last 25–30 years with proper maintenance. Inverters and batteries may need replacement earlier (10–15 years).

Yes, minimal maintenance is required – mainly cleaning panels every few weeks to remove dust, and occasional system checks.

Solar panels usually come with a 25-year performance warranty, inverters with 5–10 years, and batteries with 5–15 years depending on the brand.

On-Grid: Connected to the utility grid (net metering possible). Off-Grid: Works independently with batteries, no grid connection. Hybrid: Combination of both – grid + batteries for backup.

Your roof should get enough sunlight (south-facing is ideal), have enough space, and be structurally strong. A site survey helps determine this.

On average, each 1 kW of solar capacity produces 4–5 units per day in most parts of Pakistan, depending on sunlight and weather.

Typically, 100–120 sq. ft. per 1 kW is required, depending on panel type and efficiency.

Most modern inverters come with a mobile app or monitoring system that shows daily, monthly, and total generation.

Yes, systems can often be expanded by adding more panels or upgrading inverters, as long as the roof space and grid approval allow it.

It depends on your needs: On-grid: Best for reducing bills with net metering. Off-grid: Best for remote areas without grid access. Hybrid: Best for both savings and backup during outages.

A hybrid system gives you both net metering benefits and backup power during outages, making it more flexible.

Lithium-ion (LiFePO4): Long life, fast charging, higher cost. Lead-acid (AGM/gel): Cheaper, shorter life, needs maintenance.

On-grid systems are usually the most cost-effective due to net metering and lower upfront cost (no batteries).

Net metering allows you to send excess electricity from your solar system back to the grid. In return, you get credits that reduce your electricity bill.

When your solar system generates more electricity than you consume, the excess flows to the grid. Your meter records the exported units, which are then deducted from your bill.

To qualify for net metering, you need: A grid-tied (on-grid or hybrid) solar system. A bi-directional meter installed by your distribution company (DISCO). An approved inverter (compliant with NEPRA/utility regulations). System size within the allowed limit (residential, commercial, or industrial). Ownership documents and NOC from the utility company.

Yes. You must apply to your local distribution company (KE, IESCO, LESCO, etc.), and your system must be inspected before approval is granted.

Only on-grid or hybrid systems with certified inverters. Off-grid systems are not eligible.

Save on electricity bills by using credits for exported units. Shorter payback period for your solar investment. Promote green energy and reduce reliance on the grid.

Usually 4–8 weeks, depending on your DISCO’s verification process and application volume.

No, on-grid systems shut down during outages for safety. To have backup, you’ll need a hybrid system with batteries.

Immediately turn off the main solar isolator switch and disconnect the inverter. Call emergency services and your solar provider. Do not attempt to extinguish electrical fires with water.

Switch off the main breaker instantly. Do not touch the person or equipment directly. Call emergency services first. Ensure earthing and safety compliance is checked by a qualified technician afterwards.

Standard grid-tied solar systems automatically shut down for safety. If you have a hybrid or off-grid system with batteries, you’ll still have backup power.

Note down the error code. Switch off the inverter and contact your installer or service provider. Do not try to open or repair the inverter yourself.

Ensure the system’s electrical components are not submerged. Do not touch the solar panels or wiring during wet conditions. Contact your installer to check for water damage if you suspect exposure.

Only clean panels when the system is switched off. Ensure earthing is established to prevent electrocution. If an accident occurs, cut off power immediately and call for medical help.

Isolate the battery system immediately. Move away from the area and call the installer or emergency services. Never pour water or attempt to open the battery casing.

Yes. Quality systems include surge protection, circuit breakers, earthing, and automatic shut-off features during emergencies.
