Solar Project Collector Module (KD-PCA)
Advantages:
* Working principle: The selective coating on the inner layer of the vacuum tube transfers the solar energy into heat energy to heat the water. The hot water flows into the storage tank. This transference is enhanced by the circulation pump and relat..
