Hi Guys, I am looking for someone who can help me to design a large garden solar lamp.
I have 8 panels I want to put together (can only use these because of dimensions), each panel has a peak power of 18W, Voltage 19.4V, Current 0.92A and an Open Circuit Voltage of 23.7 Volt.
I want to build a larger lamp by using 25-30 high bright LED`s, each approx 120 lm.
I need a simple circuit with integrated controller and the light should go on when starting to get dark and go off after 6 hours.
I need the calculation of the system, led`s and battery plus the circuit/board.
Who can help me? Willing to make a small contribution
Michael
