Can the DualSun panel be installed with a drain-back system?

Nowadays, the main reasons that push installers to prefer a drain-back system concern the overheating and subsequent denaturation of the glycol.

With DualSun, this kind of problem is avoided thanks to the low stagnation temperature of our hybrid SPRING panel. These "drain-back" systems therefore do not offer any real advantages.

It is not possible to combine DualSun SPRING hybrid solar panels with a self-draining system because the DualSun Spring connections are flexible and form low points. Therefore, the draining cannot be total and creates a risk of freezing water in case of frost.
