Frequently Asked Questions

General Solar Energy Basics

What is solar energy and how does it work in Pakistan?

Solar energy uses sunlight to generate electricity through photovoltaic (PV) panels. In Pakistan, where sunlight is available most of the year, solar panels convert direct sunlight into DC power, which is then turned into usable AC power through an inverter. The energy can power homes, offices, and factories, reducing dependence on the grid and cutting energy bills.

Is solar energy worth installing in Pakistan?

Yes. With long hours of sunlight, increasing electricity prices, and frequent load-shedding, solar systems in Pakistan offer fast payback and long-term savings. It’s one of the most reliable energy solutions for both residential and commercial users.

What are the environmental benefits of solar for Pakistan?

Solar energy reduces carbon emissions, lowers air pollution, and decreases reliance on fossil fuels. Every system installed helps Pakistan move toward cleaner, sustainable energy and contributes to climate resilience.

Solar System Types & Technology

What is the difference between on-grid, off-grid, and hybrid systems?

• On-grid systems are connected to the national grid. They export surplus energy and benefit from net metering.

• Off-grid systems work independently using batteries to store energy for night or backup use.

• Hybrid systems combine both, offering grid connection with backup battery storage, ideal for areas facing power cuts.

Which solar inverter is best for Pakistani conditions?

The best inverter is one that handles heat, voltage fluctuation, and load changes efficiently. AA Power Solutions recommends reliable brands like Inverex, and Photon, both tested for local temperature and grid stability.

How do solar batteries work and which type is best?

Batteries store excess power produced during the day for use at night or during load-shedding. For Pakistan, lithium-ion batteries are preferred because they last longer, charge faster, and require less maintenance than traditional lead-acid ones.

What’s the difference between string and micro inverters?

• String inverters connect multiple panels in a single circuit, ideal for wide, unobstructed roofs.

• Micro inverters attach to each panel, offering better performance when panels face different directions or partial shading.

Costs, Financing & Value

What is the price of a 5kW, 10kW, or 20kW solar system in Pakistan?

The total cost depends on the system size, brand, and installation quality. AA Power Solutions offers competitive pricing with full installation, inverter, and mounting structures included. Larger systems like 10kW and 20kW offer better cost-per-unit value.

How much does installation cost for homes and businesses?

Installation charges vary based on system type and roof structure. Residential setups are generally simpler, while commercial projects may include additional wiring, safety, and mounting requirements.

What is the payback period for a solar system in Pakistan?

Most users recover their investment within a few years through reduced electricity bills and net metering credits. After payback, the system generates free electricity for the remaining lifespan — often 20 years or more.

Are there government incentives or net metering benefits?

Yes. Pakistan’s net metering policy allows users to sell excess electricity to the grid and receive bill credits. This system is approved by NEPRA and available through licensed installers like AA Power Solutions.

Can I get a loan or financing for solar installation in Pakistan?

Several banks and institutions offer solar financing plans for households and businesses. AA Power Solutions can help guide you through financing partners and eligibility requirements.

Installation & Feasibility

How to choose the right solar installer in Pakistan?

Look for a certified company with proven experience, high-quality equipment, and after-sales support. AA Power Solutions provides end-to-end services including site inspection, system design, and post-installation monitoring.

Is my roof suitable for solar panel installation?

Most roofs in Pakistan are suitable if they receive direct sunlight for at least 4–5 hours daily. Flat and open rooftops are ideal for maximum power generation.

Can solar panels be installed on flats or commercial roofs?

Yes. Panels can be mounted on residential buildings, apartments, and large commercial roofs using customized structures designed for stability and airflow.

What steps should I take before installation?

1. Assess your energy usage.

2. Schedule a site survey with AA Power Solutions.

3. Review system design and quotation.

4. Approve installation and net metering documentation.

Solar System Performance & Maintenance

How well do solar panels perform in summer and dust?

Solar panels work efficiently even in high heat, but regular cleaning is key. Dust buildup can reduce performance by 10–20%, so monthly maintenance ensures consistent output.

How long do solar panels last in Pakistan’s climate?

High-quality panels have a lifespan of over 20–25 years. AA Power Solutions installs panels with strong warranties to ensure durability against heat, humidity, and dust.

Do solar panels work during cloudy or rainy days?

Yes, though output may decrease slightly. Panels still capture diffused sunlight and generate enough energy for basic usage or battery charging.

What maintenance do solar panels need?

Maintenance involves cleaning panels, checking wiring, and monitoring inverter performance. AA Power Solutions offers periodic maintenance packages for worry-free performance.

Appliance Usage & Capacity

Can I run air conditioners, fridges, and other appliances on solar in Pakistan?

Yes. Properly sized systems can run air conditioners, fridges, washing machines, and more. The key is matching your system capacity to your household load.

What size solar setup do I need for my home or office?

A professional assessment calculates your daily energy consumption. For example, a small home may need around 5kW, while offices or large homes often require 10kW or more.

Can I run heavy appliances or multiple ACs with solar?

Yes, but you’ll need a larger inverter and battery capacity. AA Power Solutions designs systems based on your total wattage and usage patterns.

Is solar backup reliable during load-shedding?

With the right battery setup, yes. Hybrid systems with lithium batteries provide uninterrupted power during load-shedding or grid failure.

Net Metering, Selling Power & Regulations

What is net metering and how does it work in Pakistan?

Net metering allows you to send excess solar energy to the national grid and get credited for it. Your meter records both import and export units, reducing your overall bill.

How do I sell excess electricity to the grid?

Once your system is net-metering approved, excess energy automatically flows to the grid. You earn credits that offset your future consumption.

How is net metering approval obtained?

AA Power Solutions manages the full process, from system documentation to DISCO submission and inspection, ensuring approval under NEPRA’s policy.

Are there any restrictions for net metering in Pakistan?

Yes, systems must meet NEPRA’s technical and safety standards. Only licensed installers can submit net metering applications.

Quality, Brands & Warranties

Which brands are most reliable for solar panels and inverters?

Leading brands in Pakistan include Inverex, Tesla, Longi, JA Solar, Canadian Solar, and Growatt. AA Power Solutions offers certified equipment with verified warranties.

What warranties come with solar panels, inverters, and batteries?

Panels often carry 10–12 years of product warranty and up to 25 years of performance guarantee. Inverters and batteries usually come with 2–5 years, depending on the brand.

Why do solar prices and quality vary among installers?

Price differences come from product grade, warranty period, inverter efficiency, and installation quality. Cheap systems often use lower-efficiency components that fail early.

After-Sales Service & Support
