Sound familiar?
One roof. So many questions.
A big purchase shouldn’t come down to a brand name and a number at the bottom of a quote.
- “Do I actually need a 10 kW system?”
- “Will this battery run my AC at night?”
- “What’s missing from this quotation?”
- “I already have panels. Should I add a battery now?”
- “Who helps if something goes wrong?”
Already on solar?
Store your daytime power instead of selling it cheaply.
Many Pakistani homes installed panels first and are now adding a battery or moving to a hybrid inverter. Export rates for new net-metering connections have been cut sharply, and load-shedding has not gone away. Using more of your own power, and keeping the lights on at night, is now the reason most owners upgrade.
A retrofit is not the same job as a new install. What is already on the roof, on the wall and in your net-metering agreement decides what makes sense.
Usable backup, not box numbers
Battery size measured against the loads you actually want to run at night and through an outage.
Compatibility and paperwork
Inverter and battery compatibility, warranty terms, protection, and what a change means for your existing net-metering connection.
What we look at
Beyond panels and a price tag.
We connect the technical details to what they mean for your home, then put it in writing.

People behind the process
Your point of contact, through the purchase.
We help you understand the proposal, raise the right questions and coordinate the next step with the installation partner.
We’re starting with one installer partner. That means a focused, hands-on service, with a clear distinction between our review and the partner’s installation work.
You decide when to move forward. Final scope, responsibilities and any additional fees are confirmed in writing.
A few things to know
Good questions. Straight answers.
Still unsure? Send us a message and we’ll reply in plain language.
Ask us on WhatsAppDo I need to know anything about solar?
No. You can share your electricity bill, or simply tell us your requirements, budget and what you want to power during an outage. No document is required for the consultation route.
Can you review a quotation I already have?
Yes. Send the quotation through our quote review form. We look at the proposed equipment, missing information, pricing and whether the setup fits your needs.
Is WattPK an installation company?
WattPK helps you understand and manage the purchase. Installation is carried out by an installation partner. We are starting with one partner, so this is not a comparison of offers from several installers.
How much does the assessment cost?
The current written assessment fee is PKR 2,000. We confirm that we can help before you pay. Any additional purchasing or coordination service is agreed separately in writing. You are not committing to buy a solar system.
I already have solar. Can you help me add a battery or move to hybrid?
Yes. Tell us what is installed today, whether you are on net-metering, and what you want to keep running during outages. We check whether your inverter can take a battery, whether a hybrid replacement or an add-on battery inverter makes more sense, how much usable backup you would actually get, and what to confirm about warranties and your existing connection before anyone touches the system.
Do I need an account?
No. Submit as a guest and keep the private request link shown after submission. An account is optional.
Will you share my number with installers?
Your bill and contact information are used to review your request. We ask before releasing your contact details for installer coordination.
Start with what you have
Your solar questions. Our starting point.
You bring the questions. We’ll help you find a way forward.
