Most buyers in Pakistan spend more time researching a smartphone than they do evaluating the solar company they are about to hand PKR 500,000 or more to.
Knowing what to ask before buying solar is not about being difficult. It is about protecting a long-term investment. The right questions before buying solar panels reveal whether a company is experienced and trustworthy or whether they are optimized for the sale and not the relationship that follows.
This solar company checklist covers every category a serious buyer should address: the company itself, the proposed system, product quality, pricing, warranty, long-term service, and trust signals. Use it as your solar buying checklist before signing anything.
Questions About the Company
Choosing a solar provider starts with understanding who you are actually dealing with. The product matters less than the company behind it if that company disappears after the sale.
How long have you been in business?
Years in business is not everything, but it is meaningful. A company with several years of operation in Pakistan’s market has navigated monsoon seasons, dust cycles, load-shedding patterns, and warranty claims. Ask for the date of company registration, not just when they entered the solar market.
Can you share a portfolio of previous projects?
Completed installations tell you more than any brochure. Ask for project photos, system sizes, and locations. A company with a genuine project portfolio does not hesitate to share it.
Do you have customer references I can contact?
Previous clients are the most reliable source of information about the real purchase experience. Ask specifically for customers whose systems have been running for at least two years so you can get honest feedback about after-sales support, not just the initial installation.
Are you a registered company with a physical office?
A local presence with a verifiable physical office means there is a place to go if something goes wrong. A registered company in Pakistan has legal accountability that a WhatsApp-only operation does not. Ask for company registration documentation and the office address, then verify independently.
Which brands do you officially work with?
There is a meaningful difference between a company that is an official distributor or authorized dealer and one that simply sources products from open markets. Ask for manufacturer authorization letters for every brand they propose.
What is your service coverage area?
If the company’s service team is based in Lahore but your system is in Peshawar, after-sales support becomes logistically complicated. Confirm that service coverage actually extends to your location with a dedicated team, not just occasional visits.
Questions About the Proposed Solar System
Before accepting any recommendation, understand why that specific system was proposed for your situation. A generic package pushed to every buyer regardless of load profile is a warning sign.
Why are you recommending this specific system for me?
The answer should reference your actual energy consumption, your DISCO feeder situation, your roof characteristics, and your budget. If the answer is “this is our most popular package,” that is not a system recommendation. It is a sales pitch.
How did you calculate my energy requirements?
A proper load calculation accounts for every significant appliance, its wattage, and its daily usage hours. Ask to see the load calculation in the quotation. If no load calculation was performed, the system size is a guess.
Can this system be expanded later?
Future battery expansion, additional panels, or increased inverter capacity may become relevant as your energy needs grow or as battery prices decline. Confirm whether the proposed inverter supports parallel expansion and whether the conduit and cable routes are sized to accommodate future upgrades.
What is the expected annual energy production?
A reputable company provides a performance estimation based on your location’s peak sun hours, panel efficiency, system losses, and shading analysis if relevant. This figure lets you validate actual performance against expectations over time.
Have you accounted for shading on my roof?
Partial shading from water tanks, parapets, or neighboring buildings can reduce production by a meaningful amount depending on the inverter and panel configuration. Ask whether a shading analysis was conducted and how it affected the recommended system design.
Questions About Product Quality
Pakistan’s solar market has a genuine problem with misrepresented products. Tier 1 panels sold under unfamiliar names, refurbished inverters, and generic battery cells with premium brand stickers are documented issues. Verifying product quality requires more than taking the company’s word for it.
Are these Tier 1 solar panels from an authorized manufacturer?
Tier 1 classification from Bloomberg New Energy Finance indicates the manufacturer meets financial and quality benchmarks. Ask for the specific panel model and manufacturer name, then verify the panel exists on the manufacturer’s official product page. Manufacturer authorization letters from the distributor should be available on request.
How can I verify the product serial numbers?
Genuine solar panels and inverters carry serial numbers that can be verified against the manufacturer’s warranty registration database. Ask whether serial number verification is possible and whether the company registers products in your name at the time of purchase.
Are the inverter and batteries officially sourced?
Ask for documentation confirming the company purchased these products from an official distributor, not from grey market sources. An official distributor relationship is traceable; a grey market purchase is not.
What product certifications do these components carry?
For the Pakistani market, ask specifically about IEC certification for panels and whether inverters carry CE marking or equivalent. Ask whether the battery carries a BMS certification and which third-party testing the cells underwent.
Questions About Pricing
Comparing solar quotations properly requires understanding exactly what is and is not included. A PKR 50,000 difference between two quotes can mean the cheaper one excludes earthing, conduit, circuit breaker upgrades, or the net billing application fee.
What exactly is included in this quotation?
Ask for a line-by-line breakdown: panels, inverter, battery if applicable, mounting structure, DC and AC cabling, circuit breakers, surge protection, earthing, conduit, monitoring device, and net billing application. If any of these are absent, ask why.
What is excluded from this quotation?
Ask explicitly what the buyer is responsible for separately. Civil works, rooftop waterproofing, electrical panel upgrades, and DISCO application fees are common exclusions that add cost after the initial quote is accepted.
Are there any potential hidden costs?
Ask whether the quoted price is fixed or subject to revision based on site conditions. Ask what triggers additional charges and how those are communicated and agreed before work proceeds.
How long is this quotation valid?
A quotation validity period matters in a market where panel and inverter prices fluctuate. Know whether the price you are comparing today will still be honored at the time of installation.
What is the payment schedule?
Understand when payments are due relative to delivery, installation, and commissioning milestones. A company asking for full payment upfront before any equipment is delivered warrants scrutiny. Milestone-based payment schedules are standard practice among professional providers.
Questions About Warranty and Support
Most buyers ask whether a warranty exists. Few buyers ask what it actually covers, who enforces it, and what the claim process looks like. These are the questions that matter.
Who handles warranty claims: you or the manufacturer directly?
Know in advance whether the solar company is your point of contact for warranty claims or whether you would need to escalate to the manufacturer independently. A professional company handles warranty claims on your behalf.
What does the warranty cover and what does it exclude?
Warranties typically cover manufacturing defects and performance degradation. They typically exclude physical damage, improper installation, and acts of nature. Ask for the exclusions in writing before purchase, not after a claim is denied.
Is the warranty registered in my name?
Some manufacturers require warranty registration to activate coverage. Ask whether the company registers your products in your name at the time of installation, and request the registration confirmation documentation.
Can the warranty be transferred if I sell the property?
A warranty transfer policy adds value to your property and is a legitimate factor in evaluating product and company quality. Ask specifically whether the panel and inverter warranties transfer to a new owner and what that process requires.
What is the warranty claim process and typical resolution time?
Ask for a step-by-step description: who you contact, what documentation is required, what the typical response time is, and what happens if a product needs replacement rather than repair.
What is the local warranty support arrangement?
A manufacturer warranty is only as good as the local entity that enforces it. Confirm that warranty claims can be resolved in Pakistan, with local replacement stock available, rather than requiring international escalation.
Questions About Long-Term Service
The sale is the beginning of a 25-year relationship with your solar system. The company you choose needs to be accessible and capable of supporting that system for its entire operational life.
Do you offer scheduled maintenance?
Ask whether the company provides annual inspection services, what they cover, and what they cost. Systems that receive periodic professional inspection consistently outperform those that receive none.
What is your response time for service calls?
Ask for a specific commitment, not a general assurance. If the inverter faults at 7am on a Monday before a business day, how quickly can a technician be at the site?
Do you support firmware updates for the inverter?
Hybrid inverter firmware updates improve performance, fix bugs, and add features over the system’s lifetime. Ask whether the company provides remote or on-site firmware update support and whether this is included in the purchase or billed separately.
Who do I contact for monitoring support?
Confirm the specific contact channel for monitoring system issues, inverter alerts, and performance queries. A dedicated technical support number or ticketing system is more reliable than routing everything through a general sales line.
What happens if spare parts are needed several years after installation?
Ask whether the company maintains spare parts inventory for the brands they supply and how long product support is expected to continue for the specific inverter and battery models being proposed.

Questions About Trust and Credibility
Can I visit a previous project similar to mine?
Seeing an installed system in person, and speaking with the owner, gives you information no brochure or review can provide. A company confident in its work facilitates this without hesitation.
Are your online reviews genuine and verifiable?
Ask the company to point you to their Google Maps listing and check the review history independently. Look for reviews spanning multiple years that discuss both the sale and the post-installation experience. Independent reviews on community forums and Facebook groups carry more weight than testimonials curated on the company’s own website.
Do you have documented case studies?
Case studies showing system size, expected versus actual performance, and customer feedback demonstrate technical competence and result accountability that generic testimonials do not.
What business registration and certifications can you provide?
Ask for the company’s National Tax Number (NTN), SECP registration, and any relevant industry certifications including AEDB vendor registration. These documents verify the company operates as a legitimate registered business in Pakistan.
Do you carry professional indemnity or business insurance?
Insurance is not standard across Pakistan’s solar market, but it is a meaningful trust signal. A company carrying professional indemnity insurance has made a financial commitment to its own accountability.
Red Flags You Should Never Ignore
Knowing what questions before choosing a solar company to ask is valuable. Knowing what answers should stop the conversation is equally important.
Pressure to sign today: A legitimate solar company gives you time to compare proposals and make an informed decision. Urgency tactics are designed to prevent you from doing exactly that.
The cheapest quote with no explanation: If a quote is significantly below market range for equivalent components, something is different. Ask what was removed or substituted to reach that price.
No written quotation with itemized components: Any company unwilling to provide a detailed written proposal before payment is not operating transparently. Do not proceed without one.
No manufacturer authorization for the products they sell: Inability to produce authorization letters for the brands they propose suggests the products may be sourced from grey markets with no local warranty support.
Vague or verbal-only warranty commitments: If warranty terms are not in writing before purchase, they have no legal or practical weight after a fault occurs.
No customer references for completed projects: A company that cannot or will not provide references from past customers is a company without a track record worth referencing.
Unrealistic performance claims: Promises of zero electricity bills, guaranteed payback in one year, or production figures significantly above what the system size and local irradiance would support are marketing claims, not engineering estimates.
No process for after-sales support: If the company cannot clearly explain what happens after installation when something goes wrong, the support does not exist as a structured offering.
