Sunflare modules are more flexible than silicon-based solar panels for cars. That makes them easier to install and eliminates the micro-cracking that silicon cells experience after the flexing of sport and recreational driving. Micro-cracking compromises the electrical integrity and reduces the power output of the panels over time.
In addition, the Sunflare panels are better in partial shade. Each cell has a bypass diode so that only the shaded cell turns off. Other panels are set in strings so that if one cell in a string is shaded, the whole string goes out. Depending where the shade is hitting, the whole panel can be knocked out.
