OK, but not for solar panel – DC-DC Converter Auto Step-Up Step-Down Solar Power Supply Module - Red Reviews

posted by Alexketto on 12/10/2012 Certified Owner

Involvement:General (knows how to use it) - Ownership:1 day to 1 week

Pros:
Excuse me, for my english. Good construction. No other parts needed. Fully adjustable output voltage within the specified value.
Cons:
This solar panel can not be used because of low internal resistance to completely overload the solar cell, the solar cell voltage drops to 1-2 volts on which this module is no longer working, so there is no output voltage. The solar cells in current generator mode, the internal resistance is so high.
Other:
If you would solve the use of solar panels, it would be a very nice gadget.
Bottomline:
Good, goog, but the Solar Power Supply?
