Solar installations can be seen everywhere today, and many more are planned – both large solar parks and small installations, privately on house roofs. In addition, there are even smaller applications with an output of just a few watts. Inverters or charge controllers with MPP trackers are commonly used to optimize energy yield. Optimization of a system using real light is difficult due to fluctuating conditions. This article describes a simple and inexpensive solar panel simulator that electronically mimics a 50-W solar panel.

This is the prototype of an ‘electronic organ’ (by DC0BM) to be soldered together over the Easter holidays by a group of youngsters, hoping to enthuse them about electronics - and possibly about ham radio.

J'entreprends ici une courte série de vidéos couvrant l'analyse, l'assemblage et le mise en route d'une kit de poste de radio FM. On va y aller, un étage à l...
