We camp off grid lots. Not all enjoy that I get it. It's what makes us a interesting group. We all enjoy what we enjoy. I also get learning stuff - even stuff I'll never do. You never know what can add to your enjoyment of life.
Below is a post I posted on another forum .....
Solar Panel Built
Why and what not......
I took on this project to learn and teach myself about solar power, solar panels and solar controllers. As we all know there are a lot of very 'helpful' folks on the internet. Sorting the facts from the alternative facts is a full time job.
My project by its nature is a throw away. I believe ALL lessons cost money. Thank god for the cheap ones. My plan now is the use this setup in the 'real' world so I can learn what improvements I'll need.
Parts List Renogy Solar Starter Kit . $95 Renogy MC4 Tool . $5.50 Super Cloud Extension Connector Terminals. 1Ft . $9.00
Renogy-10Ft-Adaptor-Female-Connectors . $21.00
Construction Note
I knew it but its worth repeating Lazy Daze is not know for using too much wire. The hardest part was getting the battery out so I could attach the extension connector to the plus battery terminal. Once the battery terminal connectors where in place the rest of the construction was plug, screw down, and play.
Lesson learned so far.
MPPT and PWM -- the difference is more to do with the use and application is what is better. They both will produce, in the same price range the same amount of power.
Cost -- the price of a controller will get you more bells and whatnot but they all seem to produce the same amount of power.
The controller you SHALL have should be based on the amps your solar panels will be producing. I.E. 10 amp controller for a set of 10 AMP panels etc.
All controllers produce large amounts of heat. Get one with a good heat sink.
