Illustrative report · Not a customer caseYour solar decision, explained.
A sample of how WattPK brings your requirements, equipment, cost and next steps together. All details and prices below are fictional examples, not current market benchmarks or a recommendation for your home.
- Requirements
- Lights, fans and a refrigerator during outages. Occasional AC backup is desirable, but the budget is limited.
- Proposed setup
- An 8 kW hybrid system with an optional battery. Final sizing needs electricity usage, a load review and a roof survey.
- Assumptions
- Usable roof area, shading, actual appliance loads and installation conditions have not yet been checked. Generation and backup duration are not guaranteed.
- Panels
- The example proposal specifies 14 panels at 580 W each, totalling 8.12 kW. Confirm exact model, source and warranty documentation.
- Inverter
- 8 kW hybrid inverter. Confirm the exact model, electrical phase, supported battery and local warranty process.
- Battery option
- 5.12 kWh nominal capacity. Usable energy and backup time need to be checked against the actual loads. AC backup has not been confirmed.
- Structure & protection
- Ask for the mounting specification, cable sizes, breakers, surge protection and earthing as written scope items.
- Installation & handover
- Confirm labour, testing, monitoring setup, handover documents, paperwork and any excluded work.
- Panels
- PKR 250,000
- Hybrid inverter
- PKR 250,000
- Optional battery
- PKR 250,000
- Structure, wiring & protection
- PKR 200,000
- Installation & commissioning
- PKR 100,000
- Without the battery option
- PKR 800,000
- Still to confirm
- Tax treatment, application charges, civil work, quotation validity and payment milestones. These are not assumed to be included.
Our recommendationAsk for a revised, itemised quotation and a site survey. The proposal addresses the main requirements, but it does not yet establish the promised backup or complete installation scope.
- What looks useful
- A hybrid proposal with a separately priced battery gives the homeowner a clear choice about backup.
- What to clarify
- Exact equipment models, compatible battery, usable capacity and the loads that will be supported.
- What to change
- Replace general descriptions such as ‘accessories’ with a defined protection, wiring and mounting scope.
- What to discuss
- Payment milestones, exclusions, installation schedule and who handles each warranty.
- 1. Clarify the proposal
- Ask the installer to resolve the missing specifications and backup assumptions.
- 2. Arrange a site survey
- Confirm roof suitability, cable routes, electrical conditions and final system design.
- 3. Review the final quotation
- Agree on the price, exclusions, payment schedule and installation responsibilities in writing.
- 4. Choose how to proceed
- Accept, ask for changes or pause. WattPK can discuss further purchasing coordination separately.
