Welcome to WikiSolar !

Everything you need to know about Solar Projects and Engineering !

Here, all the concepts of PV systems are explained and illustrated in a pragmatic way as we use them in the all-day life of solar industry projects.

This website covers or will soon cover, the main components of PV systems, main architectures, engineering guidelines, as well as safety guidelines and best practises during and after installation.

We provide free drawings and templates in their raw format to help you on your projects.

About the WikiSolar team

WikiSolar is a place where you can find everything you need to know to build Solar Projects accross the world.

This website is done by people working in the Solar and Renewable industry, working from small home systems, microgrid, and up to the biggest Solar Farms. The only goal is to make Solar projects development, design, installation and commissioning, easy and accessible to anyone around the world.

We are convinced that today and at our small level, the most effective action to counter global warming is to share our knowledge so that the entire solar industry can improve and grow together. We believe that there will be enough opportunities in the world in the years to come that it is not necessary to hide knowledge in order to be more competitive than another company. Improvement of entire solar industry will increase the credibility of the sector which will benefit us all.
