Our Core Solar Systems Sub-Services
Below is the complete list of solar services Karachi Repairs offers. Each one is a standalone solution, and you can book any single service individually based on what you need.
1. Hybrid Solar System Installation
A hybrid system combines solar power, grid electricity, and battery storage in a single setup. During daylight hours, panels power your home and charge the battery. At night, the battery carries the load, and if it runs low, the system automatically switches over to K-Electric. This is the best option for anyone who wants to avoid both load shedding and high bills at the same time. When installing hybrid inverters, Karachi Repairs studies your actual daily consumption first, so the system is neither oversized nor undersized for your needs.
2. On-Grid Solar Installation
On-grid systems suit people who don't want to invest in batteries but simply want to cut down their electricity bill. In this setup, surplus power is fed back to K-Electric through net metering, and you get credit adjusted against your bill. It's the most affordable solar option with the fastest payback period. Karachi Repairs also manages the entire net metering paperwork so you don't have to run back and forth to K-Electric offices yourself.
3. Off-Grid Solar System Setup
An off-grid system runs completely independent of the national grid. It's ideal for areas where grid connectivity is weak or unavailable, such as remote industrial sites or farmhouses. Battery capacity plays the most critical role here, since the entire load depends on it. Our team calculates sizing carefully so night-time load runs without interruption.
4. Commercial & Industrial Solar Solutions
Factories, warehouses, schools, and offices carry a completely different load profile compared to residential setups. Karachi Repairs designs large-scale solar plants for commercial clients, including three-phase inverters, proper cable sizing, and balanced load distribution. We study your production hours and peak load timing to design a system that meaningfully reduces operational costs. We've already completed multiple commercial installations across Korangi, SITE Area, and Landhi.
5. Acid Tubular Battery Bank Upgrade
If your existing tubular battery bank has weakened or your backup time has dropped, we handle the upgrade. Tubular batteries remain popular because their upfront cost is lower than lithium. Our team checks the health of your existing batteries, rewires connections, and, where needed, increases bank capacity to meet your actual backup requirement.
6. Solar Inverter Installation
The inverter is essentially the brain of the whole solar system. A poor-quality or mismatched inverter drags down the performance of the entire setup. Karachi Repairs installs reliable, branded inverters built to handle Pakistan's voltage fluctuations and variable loads. We also help you select the right KVA rating for your current and future load, so you don't need to spend again later for expansion.
7. Lithium-Ion Bank Upgrade
Lithium batteries are gaining popularity fast because they last significantly longer than tubular batteries and require almost no maintenance. They're also more compact and offer better charging efficiency. For clients who want to convert their existing lead-acid or tubular banks to lithium, our team installs a properly sized lithium bank paired with the correct BMS (Battery Management System).
8. Solar DB Panel & Safety Breaker Installation
Safety is the most important part of any electrical system, and it becomes even more critical in solar setups because both DC and AC sides carry risk. Karachi Repairs installs proper DB panels, MCBs, and safety breakers that protect against short circuits, overloads, and fire hazards. We also make sure earthing is done correctly, which is especially important in a humid city like Karachi.
9. Solar Panel Installation
Panel quality and their tilt or angle have a direct impact on your generation output. Our team surveys your roof carefully to determine the best positioning, so panels receive maximum sunlight and avoid shading issues. We install both mono-crystalline and poly-crystalline panels, recommending the right option based on your budget and available roof space.
10. Inverter Fault Troubleshooting
If your existing inverter is showing an error, refusing to charge, or has suddenly shut down, our technical team is available for same-day diagnosis. Using proper diagnostic tools and multimeters, we identify the exact fault — whether it's an MPPT issue, a loose wiring connection, or a battery connection problem — and repair it onsite whenever possible.
11. Solar System Relocation
Moving homes or shifting your office and want to take your solar system with you? Our team safely uninstalls the complete system and reinstalls it professionally at the new location. Panels, wiring, and the inverter are all retested to make sure the system performs at the same efficiency after relocation.
12. Onsite Consultation
Not sure which system fits your needs? Our team offers a free onsite visit where we review your electricity bills, measure your roof space, and recommend the best possible solution without any pressure to buy. This consultation also gives you a clear budget and timeline, so you can make an informed decision.
Why Choose Karachi Repairs
There are plenty of solar installers in the market, but a few things set Karachi Repairs apart.
Locally Stationed Teams
First, our teams are locally stationed across the city, which means faster response times wherever you're located.
Unbiased Brand Recommendations
Second, we're not tied to just one or two brands — we choose from multiple reputable brands based on the client's actual requirement and budget, so there's no bias in our recommendations.
Complete Transparency
Third, transparency matters to us. Before sending a quotation, we break down the full system for you — the number of panels, inverter rating, battery capacity, and labor cost — so you know exactly where your money is going.
Full After-Sales Support
Fourth, our team doesn't just install and leave; we maintain a full after-sales support system, so you can report any fault at any time and our nearest team reaches you within 30 minutes.
Installation History Records
We also keep a record of every installation we complete, so if you call us months or even years later, our technicians already have context on your system's specifications and installation history, which saves time during troubleshooting.
Residential & Commercial Scale
Finally, and just as importantly, we work across both residential and commercial scale — whether you need a small 3kW home system or a 50kW industrial plant, our team is equipped to handle either.
Common Mistakes People Make With Solar Systems
As solar demand has grown rapidly across Karachi, so have poorly executed installations that end up causing problems for clients later on.
Choosing Cheap Installers
The first common mistake is choosing the cheapest installer available without checking whether their team is certified or what quality of equipment they use. This gets a system installed quickly, but faults often start appearing within just a few months.
Skipping Load Calculation
The second mistake is skipping proper load calculation. Some installers size a system based purely on what the customer asks for, without checking actual bills or appliance usage, resulting in a system that's either oversized or too small to carry the full load.
Incorrect Battery Sizing
The third mistake involves incorrect battery sizing — undersizing a battery bank and then running it under heavy load shortens its lifespan dramatically.
Ignoring Maintenance
The fourth mistake is ignoring maintenance altogether. As mentioned earlier, dust buildup on panels and loose connections are common issues that, if left unaddressed, gradually degrade system performance without the client even noticing the drop in generation.
Underestimating Safety
The fifth mistake is underestimating earthing and safety devices, which is a genuinely serious risk since it can lead to short circuits or even fire hazards.
The Karachi Repairs Solution
Karachi Repairs avoids all of these pitfalls by following a strict process on every installation — a proper load audit, correct sizing, quality equipment, and safety-compliant wiring. That's exactly why systems we install tend to perform better long-term, with clients facing far fewer repeated faults.
How the Solar Installation Process Works
From Initial Call To Completed Setup
Initial Consultation
When you call Karachi Repairs, our team first takes down basic details about your requirement and budget.
Onsite Measurement
If needed, a technician then visits your site for an onsite consultation to measure roof space, check for shading, and calculate your load.
Detailed Quotation
After that, you receive a detailed quotation with every item listed separately.
Installation Phase
Once the quotation is approved, an installation date is scheduled, and our trained team arrives with the equipment. During installation, panels are securely mounted on the roof, wiring is run, the inverter and battery are connected, and safety breakers are installed in the DB panel.
Testing & Handover
Finally, the entire system is tested to make sure every component is working correctly. Once installation is complete, our team walks you through the basic operation of the system so you can monitor it yourself going forward.
What to Consider Before Installing a Solar System
Many people make the mistake of choosing a solar system purely based on price, only to regret it later. Here are the key points worth keeping in mind before making a decision.
Signs You Should Book an Onsite Consultation Right Away
Some homeowners and business owners wait too long before reaching out, either because they assume the issue is minor or because they're unsure whether their situation actually needs professional attention. If your electricity bill has been climbing steadily despite no real change in your usage habits, that's usually a strong signal that it's worth exploring solar as a long-term fix rather than continuing to absorb rising tariffs every few months.
Similarly, if load shedding in your area has become more frequent or longer in duration, relying purely on the grid stops making practical sense, especially for businesses where downtime directly affects revenue. For homes with elderly family members, medical equipment, or young children, uninterrupted power isn't just a convenience — it's often a genuine necessity, and a hybrid or off-grid setup removes that dependency on an unpredictable grid entirely.
If you already have an existing solar setup that feels like it's underperforming compared to when it was first installed, that's also worth a consultation rather than simply assuming the technology has aged out. In many cases, a simple cleaning, a battery health check, or a wiring inspection resolves the issue without needing to replace major components. Karachi Repairs offers this onsite evaluation free of charge specifically so homeowners and business owners can make decisions based on facts rather than guesswork.
Difference Between On-Grid, Off-Grid, and Hybrid Systems
This is one of the most common questions we receive, so let's break it down in detail.
On-grid systems stay connected only to the grid and don't include a battery. They generate power only while there's sunlight, and any excess is sent back to the grid. During load shedding, these systems automatically shut down, since safety regulations require grid disconnection when there's no battery backup. This is the cheapest option, but it offers no backup power.
Off-grid systems operate completely independent of the grid. All power comes from panels and battery storage. The advantage is total independence from K-Electric, but the cost of the battery bank makes this option more expensive overall.
Hybrid systems combine the best of both worlds. During the day, solar powers your home and charges the battery; at night, the battery takes over. If the battery runs low, the grid automatically kicks in as backup. That's exactly why hybrid systems are the most recommended choice in a city like Karachi, where both load shedding and grid availability are part of daily life.
What Affects the Cost of a Solar System
One of the first questions most clients ask is how much a solar system will cost, but the honest answer is that no installer can give you an exact figure without understanding the details, because cost depends on several factors. The first factor is system size — the higher the KW requirement, the more panels, wiring, and inverter capacity you'll need, which directly increases the overall cost. The second factor is battery selection. If you're going for an on-grid system without a battery, the cost stays relatively low, but if you need backup and opt for lithium batteries, the cost will be higher than with tubular batteries.
The third factor is roof condition and structure. If existing structures need to be removed or the roof needs reinforcement before installation, that adds extra labor and material costs. The fourth factor is inverter brand and quality — some clients look only for the cheapest option, but a low-quality inverter reduces system efficiency and leads to frequent faults, which ends up costing more in the long run. The fifth factor is labor and installation complexity. If equipment is difficult to transport to the site, the roof is unusually high, or the wiring route is complicated, that also adds to the total cost. Karachi Repairs only provides a final, transparent quotation after a site visit, so there are no hidden charges and you know your full budget upfront.
How Long Does It Take to Get Return on Investment
This is another question we get asked frequently — how long it takes for the money spent on a solar system to pay itself back. The answer depends on your current electricity bill, system size, and usage pattern. On average, residential on-grid systems have a payback period of three to five years, while hybrid systems that include battery storage may take slightly longer due to the higher upfront investment.
Commercial and industrial setups often see a faster payback period, since their monthly electricity consumption is much higher than residential usage, meaning savings show up sooner and in larger amounts. On top of that, solar panels typically last 20 to 25 years, so even after the payback period, you continue benefiting from free electricity for years afterward. That's why solar should be viewed not just as an expense, but as a long-term investment that keeps paying off financially over time.

Frequently Asked Questions
How many KW of solar system is enough for a home in Karachi?
It depends on your monthly consumption. A small family using an AC, fridge, and normal appliances usually needs 3 to 5 KW, while a larger home running multiple air conditioners may require up to 8 to 10 KW. Getting an onsite consultation is the best way to determine the correct sizing.
How long does it take to install a solar system?
Residential installations are typically completed within one to two days, while commercial or industrial systems can take longer depending on their size. Karachi Repairs provides a clear timeline once the quotation is approved.
Does my electricity bill drop to zero after installing solar?
If the system is correctly sized and matches your load, your bill drops significantly, and on-grid systems with net metering can even generate credit. However, dropping to absolute zero depends on your system's capacity and actual usage.
Is a lithium battery better than a tubular battery?
Lithium batteries last longer, need minimal maintenance, and are more compact, but they cost more upfront. Tubular batteries are cheaper but require regular maintenance and have a shorter lifespan. The right choice depends on your budget and long-term plans.
How quickly can I get service if my inverter faults?
Karachi Repairs teams are already stationed across different areas of the city, so under normal circumstances, a technician reaches you within 30 minutes to diagnose and repair the fault.
