What these specifications mean
LONGI 550W Mono Perc Solar Panel is listed with 2 published specifications from LONGi, including watts of 545W and type of Mono Perc Solar Panel. Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.
For a solar panel, the figures that matter most are temperature coefficient of power, usually −0.26 to −0.35 %/°C, first-year and annual degradation, and the performance warranty that guarantees them, physical dimensions and weight, which decide what fits your roof and mounting and open-circuit voltage (Voc) and short-circuit current (Isc) for string design. Panels are the generating half of the system and the part that determines how much energy is available at all. They are also the longest-lived component, routinely still producing over 80% of their original output after 25 years.
Before you buy a solar panel
The checks below apply to any solar panel. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.
- Check the physical dimensions against your usable roof area before ordering. Modern modules are large, and a layout that works on paper can fail against obstructions, walkways and setback rules.
- Consider N-type TOPCon or bifacial modules where space is tight or the mounting is elevated and reflective — bifacial gains of 5–15% are realistic over a light-coloured flat roof or the ground, and close to zero flush against a dark tile roof.
- Keep every panel in a string identical in model and rating. Mismatched modules in one string pull the whole string down to the weakest one.
- Compare cost per watt rather than price per panel — a higher-wattage module is often cheaper per watt and needs fewer mounting rails, clamps and cable runs.
Where buyers lose money
- Underestimating shade. A single shaded cell can suppress an entire string unless you use module-level optimisers or microinverters.
- Ignoring certification. IEC 61215 and IEC 61730 are the baseline; without them, warranty claims and grid approvals get complicated.
- Buying the highest wattage available without checking the inverter's MPPT voltage window — a string that sits outside the window produces less, or nothing.
Price and availability in Pakistan
LONGI 550W Mono Perc Solar Panel is listed at ₨ 27,500 (PKR) for Pakistan. Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.
SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in Pakistan: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports LONGi locally before ordering.
LONGI 550W Mono Perc Solar Panel — frequently asked questions
How much does LONGI 550W Mono Perc Solar Panel cost?
LONGI 550W Mono Perc Solar Panel is listed at ₨ 27,500 (PKR) for Pakistan. The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.
What are the specifications of LONGI 550W Mono Perc Solar Panel?
We hold 2 published specifications for this solar panel, including watts 545W and type Mono Perc Solar Panel. The full table is on this page, listed under model LONI-05.
Who makes LONGI 550W Mono Perc Solar Panel?
LONGI 550W Mono Perc Solar Panel is a LONGi product, listed under solar panels with model reference LONI-05. The LONGi brand page lists the rest of its range so you can compare across the catalogue.
Is LONGI 550W Mono Perc Solar Panel right for my system?
That depends on what it has to connect to. For a solar panel, check open-circuit voltage (Voc) and short-circuit current (Isc) for string design, rated power in watt-peak (Wp) measured at standard test conditions and module efficiency, typically 19–23% on current products against the rest of your equipment before price enters the decision. Compare cost per watt rather than price per panel — a higher-wattage module is often cheaper per watt and needs fewer mounting rails, clamps and cable runs.
Where can I buy LONGI 550W Mono Perc Solar Panel in Pakistan?
SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer in Pakistan — buying in-channel is what keeps the manufacturer's warranty valid.
