After the basics of understanding the battery in our PV system we will now select the one that fits best to our application. First we will determine the capacity we need. Then we will have a look at different types of lead-acid batteries and which of them are well suited for the PV system. Continue reading →

In this post we will start to talk about the component that stores the energy from the PV module until it is used: the battery. We will build our system with a lead-acid battery. This post is about the basic function of the battery in our system and the electrical characteristics that are important to us. The next post will be about the different types of lead-acid batteries and how to choose the right type and size. Continue reading →

A standalone PV system begins with thinking about the load. So let’s talk about our load: The characteristics of the load determine all the components of the PV system because it must be designed to feed the load so that everything works the way we want it to.

In the first part of this article we will talk about choosing the appropriate system voltage. The second part is about how much electricity is consumed and how to optimize the system in a way that it needs less energy but still is fully functional.
