Simple MPPT solar panel charge controllers

I am not sure how to configure a "reflector" to equally increase the brightness on all twelve PV Panels simultaneously - that is a requirement since I have a SERIES wired system (High Voltage & Low Amps = Low Cabling Losses). The array is 5 feet tall by 38 feet long!

 

Yes, in your case you have to look on how the Spanish has done it. Their array's may have been different configured. In the thread "Batteries and new batteries technologies" I searched and found something in Spain.
It probably will only benefit a sailor, who has a single panel at the back of his boat and can easy construct a reflector. Bert

 

I've built an MPPT designed by Tim Nolan. Information available at his home page.

This design is based on arduino with a breakout board. I'm no electrical engineer so I can't elaborate to much.

Works great, and via interface to computer you can easily follow the traccing prosedure where the arduino is testing which switching ratio gives the highest performance.

Not sure how much power it's designed for, i've teste my on an 80W panel, but then the cirquit heats up quite fast.

 

I must try something. I have a circuit with 2 interwoven Flip flops and buck regulator, which is a DC to DC inverter. If I keep the secondary Voltage at 3.4 Volt or multiple thereof (as per suggestion of Groper) than I should have in principle a very inexpensive MPPT inverter. A solar panel is in anyway up to 36 - 38 Volt and we only need 6 x 3.4 = 20.4 Volt. I made that thing (refer "batteries and new battery technologies" )to prove that EEStor could easy have made a super duper capacitor, which could flatten the curve to an acceptable flat voltage for a period of time, good enough to use it as a battery.
But it is Christmas time and let see whether we can squeeze it in time wise.
