Why This Checklist Exists
Over this series we've covered pricing, panel technology, inverters, batteries, financing, installation, maintenance, and net metering as separate deep dives. This post pulls every decision into one sequence — the order buyers should actually work through them, with a link to the detailed guide for each step. Bookmark this one; it's the master reference for the rest.

The Master Checklist
- Pull 6–12 months of electricity bills to calculate average monthly units
- Decide on-grid, hybrid, or off-grid based on outage frequency and budget
- Calculate target system size using the bill-to-kW formula
- Set a total budget including financing costs, not just equipment price
- Pick a panel brand and cell technology (Mono PERC, N-Type, or HJT)
- Pick an inverter brand matched to your budget and backup needs
- Decide if you need a battery, and which chemistry/capacity fits your load
- Confirm all three components (panel, inverter, battery) are compatible
- Compare cash purchase vs SBP Green Line vs bank loan vs leasing
- Get written quotes from at least two installers for comparison
- Confirm installation labor and warranty terms are included in the quote
- Verify the installer is NEPRA-licensed before signing anything
- Book a site survey to confirm roof condition and final system design
- Complete installation and system commissioning
- Submit net metering application with all required documents
- Set up a maintenance routine once the bidirectional meter is live

Red Flags to Watch For
- Quotes with no brand names listed — vague "Grade A panels" language often hides low-tier equipment
- Installers who can't confirm NEPRA licensing — this will delay or block your net metering application
- Unusually low prices with no explanation — often a sign of counterfeit or grey-market equipment
- No written warranty terms — verbal promises aren't enforceable if something goes wrong
- Pressure to decide same-day — a legitimate quote should hold for at least a week
Work through the four phases in order — sizing first, equipment second, financing third, installation and paperwork last. Buyers who skip straight to comparing equipment prices without first sizing correctly are the ones most likely to end up with an oversized or undersized system. This checklist, paired with the linked guides, covers everything you need before signing a single quote.

Start with sizing, not equipment shopping. Pull your electricity bills, calculate your target kW, and decide on-grid vs hybrid vs off-grid before comparing any panel or inverter brands.
At least two or three written quotes, comparing not just price but brand names, warranty terms, and whether installation labor is included, to make an apples-to-apples comparison.
Sizing the system based on price alone rather than actual bill data, which leads to either overspending on excess capacity or underdelivering on savings expectations.
Not recommended — bundled installer packages typically include warranty coordination and net metering paperwork support that's harder to arrange when equipment and labor come from different sources.
Roughly 6–10 weeks from initial sizing decision to a fully credited first bill, with installation itself typically taking just 1–3 days within that window.
Yes — the same phases and red flags apply regardless of system size. Smaller systems simply move through each phase faster.
