There are several ways to attach solar panels to a roof without drilling holes, which mainly rely on using fixtures that do not require penetration of the roof:
1. Use solar panel clamps: There are clamps designed for solar panels on the market that can be fixed to the roof by clamping or suction without drilling holes.
2. Use adhesives: Some strong adhesives can be used to stick the bracket or base of the solar panel directly to the roof. But please be careful when using adhesives to ensure that they can withstand the weight of the solar panel and possible wind pressure and weather conditions.
3. Use existing roof fixtures: If there are already hooks, brackets or other fixtures on the roof, you can consider using these existing structures to fix the solar panel.
In actual operation, it is recommended to consult a solar panel installation expert or check the product manual to understand the applicability and installation requirements of different fixing methods.
