I am currently writing a series of posts about a PV system that powers the arduino and connected devices.
The second post in this series is now online. It is about the load that will be connected to the PV system. Determining and optimizing the load is the first step in dimensioning the system and making it efficient in terms of cost and resources consumption. The article is about choosing the right system voltage and how to reduce power needs to a minimum.
If interested look at:http://heliosoph.mit-links.info/solar-power-for-your-arduino-load/
The first post talks about the basics: Which components do you need and how are they connected? What is the basic function of the system?
