Distributed, or decentralised energy systems can be build with Open Source Renewable Energy Hardware. Within the Hamburg Open Online University project Collective Open Source Hardware, short cos(h), step-by-step instructions were created to build your own open source solar system. The tutorial is based on Libre Solar components and offers a modular system that can be set up, depending on power and storage capacity requirements. Basic understanding of electrical engineering and programming is required for a successful construction.

Manufacturing of a Solar Charge Controller
A charge controller feeds electrical power from solar panels (or wind turbines or bicycle generators) in the battery storage system. If electricity should be stored in batteries, a charge controller is always required, as it prevents the battery from overloading or overcurrent. Cos(h) created a manual that shows how to manufacture a MPPT (Maximum Power Point Tracker) charge controller. It is a PCB (printed circuit board) for running an electrical solar power system.

Assembly of a Solarbox
This tutorial shows you how to connect the previous constructed charge controller with solar panels, batteries and loads directly. However, a solarbox can be created individually.
Another cos(h) tutorial shows how to assemble a solarbox, which is a small scale mobile energy system (consisting of batteries, electric components like a charge controller and connectors for connecting power generation units like solarpanels)
