In this project I will show you how to create a solar tracker which like the name implies can follow the movement of the sun throughout the day. And at the end I will show you the energy harvest difference between a solar tracker mounted solar panel and a flat mounted solar panel.

Solar Panels on Our House – One Year In

After one full year of having a solar panel system on the roof of my home, I share some insights into how it’s been working. This is a grid-tied system, purchased through Vivint Solar, to generate up to 100% of the electricity we use each year. Now that I can run the numbers for a full year of use, I’ll talk about it.

In the near future I’ll explain how a new radon mitigation system in our home motivated me to contact Vivint Solar again to expand our system and generate even more electricity.
