Hi. I've been interested in renewables for a while now. Our society can't continue to work on oil, and with rising gas prices and more frequent power outages, solar energy seems to be the way to go. The main problem that inspired me to make this system comes from my love of technology. When my iPhone and laptop run out of juice, my life becomes very primitive. With the goal of keeping all my electronics up and running no matter what the weather and grid status is the main reason I made this system and instructable. This is my system and how it functions. I'll start with the original setup and show how it has evolved over time.
Step 1: The Original Setup
My original setup started off with a 10 watt panel I built myself from some cells I found off of eBay. These were the tougher CIGS cells rather than monocrystalline or polycrystalline. The cell was originally rated at 15 watts but because of all the inefficient soldered connections (I wasn't that great at soldering yet), it made about 10 watts. Each black square is one cell that makes approx. 5 volts. The voltage was combined in series to create around 20 volts, and then the amperage was adjusted with wiring the strings of 20 volts into parallel. I'm not really going to go in a crazy amount of detail because this is explained on hundreds of other instructables. This amount of power is ideal for maybe some DC lights and charging cell phones. It's not nearly enough for even my laptop. The inverter would whine and the adapter on my laptop would begin to buzz. Probably not a good sign!
*Note* The third picture to this step is a quickly drawn schematic of how everythig in this system currently works. It will help with trying to understand the basic function of the system if you are new to solar for simplicity. I'll try to include a schematic after every major change to clarify.
