New product--How to connect the solar thermal collectors with the existing tank

Hi,
We have invented the circulation pump with 4 ways valve integrated to make all the family have the solar water heating. 
Just to connect the valve with the existing tank which has the circulation connection to the solar collectors.
The circulation pump is operated by the PV panel, which running in the sunny day.

The system include the mini pump, 4 ways valve, PV panel and solar collectors, which module package, easy transportation and convenient installation, low cost.

It is suitable for any area and any home, whatever the existing tank of gas, oil, electric and heat pump。

Let's have your comments on it, thanks
