Perceived quality vs economic efficiency

SunPower Maxeon is distinguished by premium positioning, careful finishes and long warranties depending on offers.
LONGi relies on high industrial volume, which often improves the price per installed watt.
In real production, the difference can be moderate if the two systems are well sized and well oriented.

The additional cost SunPower can defend itself when the usable surface area is very limited.
For a traditional roof, LONGi is often more rational in terms of total cost and return time.
The final decision must integrate inverter, structure, installation and local after-sales service, not just the panel sheet.

Point of vigilance

Ask for the full cost per installed kWp (not just the panel price) to compare correctly.
