Karachi solar estimate at a glance
This shared model uses 5.8 peak-sun hours per day, a 75% performance ratio, 55% direct self-consumption, Rs. 60/unit retail value, and Rs. 8.13/unit export credit. These are illustrative assumptions, not an official flat K-Electric tariff. Enter the actual units from your bill, then ask your installer to recalculate savings using your agreement rates and measured daytime load.

What changes in Karachi
The 5.8 peak-sun-hour value is a planning default, not a coastal-roof survey. Clifton or seafront DHA and an inland Gulshan roof can share the same calculator value while needing different corrosion protection and exposure assessments. First confirm the utility printed on your own bill rather than assuming service from a neighborhood name.
Coastal humidity and salt exposure make mounting structure coating, stainless fasteners, cable routing, and inverter placement more important than they are in many inland cities.

Area names are examples for survey planning. Verify the actual electricity supplier on your own bill.
Net billing
K-Electric savings logic
K-Electric users should model imported units at the retail tariff and exported units at the export credit separately. A high daytime load profile usually beats oversizing only for exports.
The calculator separates direct savings from export credit because imported units and exported units have different cash values. This is why two Karachi homes with the same kW size can have different payback.
Site survey
Evidence to request for a Karachi roof
Use your own bill, roof photographs and operating schedule to turn these local checks into a written design. Ask for the evidence behind each proposal before comparing total prices.
Specify coastal protection component by component
Request the mounting finish and coating specification, fastener material and the panel manufacturer's salt-mist documentation for the exact model. Ask which coastal exposures the equipment warranty excludes. A verbal promise of a rust-free structure does not establish the specification.
Check exposed roofs and the KE application separately
For an exposed upper-floor roof, request an anchoring and wind-load design plus a waterproofing detail. Separately save the KE application reference, approved capacity and meter documentation; a larger mounting structure cannot establish whether that capacity will be accepted by the utility.
A comparison to make before you buy
For a Clifton apartment roof, settle written roof-use permission and maintenance access before comparing generation. Then compare a corrosion-specified quote with an ordinary quote using the same panel count and protection scope. The common price bands below do not include a separately surveyed coastal premium or shared-roof works.
Quote checklist
Before you sign a Karachi solar quote
Keep every installer on the same scope. Otherwise a cheaper quote may simply be missing protection gear, stronger mounting, monitoring, battery wiring, or K-Electric paperwork.
1
Confirm the K-Electric filing scope, fees, drawings, testing, inspection, and bidirectional meter timeline.
2
Ask for panel brand, exact model, wattage, serial verification, product warranty, and performance warranty.
3
Require inverter make, model, warranty channel, monitoring access, surge protection, earthing, and breaker details.
4
Separate panels, inverter, mounting, protection gear, battery, labor, and net-billing filing into line items.
5
Ask Karachi installers about anti-corrosion structure specs, inverter ventilation, warranty support, KE application handling, and whether the quote includes surge protection and earthing.
FAQ
Karachi solar calculator questions
Answers to local planning questions before you request a quote.
What changes for solar near Karachi's coast?
Check the mounting finish, fastener material, exact panel's salt-mist documentation and coastal warranty limits. Do not assume an inland Gulshan roof has the same salt exposure as a roof near the seafront.
Where should a Karachi buyer verify the KE application?
The official KE net-billing page linked below provides application, tracking and consumer guidance. Confirm the approved capacity and your agreement's billing terms before relying on export income.
Official sources
Verify the application and generation assumptions
Use the original utility sources for application rules, fees and approval steps. The sun-hours and price bands on this page are this site's planning assumptions; they are not an official tariff or a measured local yield dataset.
K-Electric official net-billing portal
KE provides application and tracking links, consumer guidance and approved-vendor links. Confirm the billing treatment and approved capacity for your own agreement.
Check monthly yield in Global Solar Atlas
Select your roof's location and compare monthly PVOUT for the proposed orientation and tilt. The Atlas model excludes building and vegetation shade, so a local shade survey is still needed. Its kWh/kWp yield is a different quantity from this calculator's peak-sun-hour input.
