Design your Residential grid-tied PV System

Welcome to our Solar System Design tool for YOUR energy independence. We are providing you with all necessary information to design your own grid-tied PV System for your home. Everything you need is to know how much you are spending on electricity every month (on average) and how much you are consuming in daytime (between 8 a.m. and 6 p.m.). Once you have put in these information and if your house has a single or three phase supply, our design tool will take over and provide you with the following information.

  • Estimated size of your Solar System
  • Required roof space without shading
  • Estimated cost incl. all expenses of your PV System
  • The payback period based on all given information

After you finished the design of your Solar System, fill in your details and click on the “Submit” button. We will get in contact with you about a detailed quote and consultation, based on YOUR design.
