Understand the panels
on your roof.

Compare panels using a datasheet, not a slogan.

Capacity, size and compatibility

Compare the rated watts and physical dimensions of the exact model. A higher wattage module may also be larger; the roof layout and access paths matter. Ask your designer to confirm inverter input limits and the proposed string arrangement.

Price per watt

Divide the panel-only price by the total rated watts supplied. Two 550 W modules total 1,100 W. A hypothetical ₹22,000 pack is ₹20/W before any separately charged delivery or other items. This calculation is not the installed system price.

Documentation to keep

Save the invoice, model and serial numbers, datasheet, installation manual and warranty conditions. Product warranty and performance warranty cover different promises; neither should be read as a guarantee of your household bill savings. Scheme eligibility must be checked for the exact equipment, not the brand name alone.
