7 Things to Check Before You Buy Solar Panels
Buying solar is a big decision, and the label on a panel only tells part of the story. Before you commit, run through this quick checklist.
1) Grade and origin. Is it genuine A-grade, first-party direct import? This is the single most important question.
2) Efficiency. Higher-efficiency panels make more power from the same roof space — important if your roof is limited.
3) Temperature coefficient. Peshawar gets hot, and panels lose output as they heat up. A lower temperature coefficient means better summer performance.
4) Degradation rate. Every panel weakens slightly each year. Good panels lose only about 0.4-0.5% a year and still make around 87% after 25 years.
5) Warranty — and who honours it. A 25-year warranty means nothing if the importer disappears. Ask who supports the claim locally.
6) Datasheet, not promises. Get the datasheet and match model numbers. Real products come with real paperwork.
7) The installer. Even the best panels underperform with bad wiring, the wrong tilt or a cheap inverter. Your installer matters as much as your panels.
Bonus: think about total system value — panels, inverter, structure, cabling and after-sales — not just the price per watt.
Do these checks and you will avoid the traps most first-time buyers fall into. Want a straight, no-pressure recommendation? Message the Al Syed Solar team and we will walk you through it.
