Description

Open source project for a solar farm with automation and testing of solar viability. Also some basic economics of the system and scaling. First goal of the project is to be able to sell the solar power to the power grid. Ultimate end goal is to combine solar power with agricultural production and do some sort of agrovoltaics.

  • Mppt and storage problems

    Fredrik Weigl • 06/15/2022 at 18:01 • 0 comments

    So i have a larger problem where my Solar Mppt charger won't work with both solar panels if the battery voltage is to low, its only rated for 360w when using a 12v system. So thats why i haven't updated in a bit and have been putting the project on bit of a hold until i get some funds to acquire a 48 volt system for energy storage. I have been doing some other projects on the side such as assembling a mobile weather station instead.

    Fredrik Weigl • 05/27/2022 at 19:40 • 0 comments

    Got my hands on a LFS105 12V 105Ah flooded batteri.

  • Stuff has arrived!

    Fredrik Weigl • 05/24/2022 at 14:04 • 0 comments

    Now most parts have arrived. Still waiting on some things but now I have gotten my hands on the more important parts so I can start experimenting. 

    I did now though noticed that I have forgotten to buy some important parts for hooking it all up together. More specifically the MC4 Connectors for the solar panel and corresponding cable for it hehe. But no worries, I will just order some. While I'm at it I might order some more interesting sensors for a weather station and some other equipment for IoT. 

    The solar pannels are much bigger then one expects haha, I diden't have a banana for scale but i did have a tomato. But damn, isn't the panel beautiful, also got that sweet matt black finish on the sides!

    Also bought some things for automation and controlling things.

    Next thing to acquire is the components for the batteries, inspired by Martin Johnson - Off Grid Living. Now i'm just waiting on all my components to arrive. Will be working on some software in the meantime.

  • The initial idea

    Fredrik Weigl • 05/09/2022 at 23:49 • 0 comments

    Here is a sketch of the system i was thinking initially with all the major components.

  • The real deal

    Fredrik Weigl • 05/09/2022 at 23:38 • 0 comments

    So after some research i decided on 2* 300w 24v solar panels. I also bought a Mppt solar charger from Victron energy. There is a lot of other version and prices, but this was the best and cheapest that fit my specs that i wanted with my budget.


  • Starting out

    Fredrik Weigl • 05/04/2022 at 20:27 • 0 comments

    So im getting the basics of solar tracking by using a Raspberry Pi and checking already open source projects available in the scope of the project. i was thinking of using a Odrive to control a motor. the idea is to following the sun in the most optimal angle, starting with one axes of movement.
