Abstract

Solaris Power project is a system capable of providing complete energy backup for the houses,offices or schools etc.

The principle of working is to convert Solar Energy (DC) into utilizable AC energy.

The main criteria in designing this project is to make it as compact as possible.

Reasons for Implementation:
