Even though I have been dabbling in solar power since about 2008 I hesitated to share my experiences because I felt totally incompetent about the subject. I still feel that way in large part, even though my “knowledge” has increased dramatically.
One of my first projects was setting up a solar-powered well for a friend’s cattle where obtaining grid power would have been financially prohibitive. The equipment included a Grundfos 11 SQ-Flex 2 pump, 6 solar panels, Midnite Solar 60 charge controller, golf cart 48-volt battery bank, etc. You may have noticed that there is no mention of an inverter because this Grundfos will run off any source of power, AC or DC, without any modification. I had already built a wood rack to hold the solar panels with an enclosed area underneath to hold the solar equipment. I was amazed that we were able to install the pump and install all solar components and get it running in one day. We had a scary moment when we turned it on and nothing happened. Before pulling the pump I checked all of the above-ground connections and found a loose wire in the charge controller. It was quite exhilarating when we heard water gurgling and had full water flow, just seconds later.
Years later — around 2015 — I decided that my prepping would not be complete without at least a minimum availability of electricity if grid power was not available. I also wanted to build a workshop and decided that would be the perfect location for solar panels and the rest of the equipment. At that time I felt the size of the project was beyond my capabilities and started the search for someone to provide me with a turnkey solution. Looking through a couple of quotes I realized the proposals left a lot to be desired in terms of power provided versus cost. I decided that I would have to do a lot of studying and learn how to accomplish the project myself. This turned out to be very confusing and I often had to sift through conflicting statements from manufacturer’s manuals and their tech support and retailers.Continue reading“Practical PV Power, by Graton”
