“And, the importance of regular visits to your Bug-Out Location (BOL).”
Back in August of 2020, I wrote about the solar photovoltaic (PV) power system at my Bug-Out Location (BOL). I believe it was General Electric that used to put on all their professional product literature, “Our policy is one of constant improvement.” That’s great advice for all of us! In the last three years, I have made some refinements and corrected some significant shortcomings in it.
My BOL is deep in the woods, a quarter-mile off the road, and is surrounded by trees. That’s great for OPSEC and natural air conditioning, but it is very challenging for harvesting solar power. Fortunately, there is a cleared corral area about fifty feet North of the house where my solar panels are located. As I detailed back in 2020, I have the main bank of solar panels facing South, with an additional panel facing East and West to catch the first sunlight in the morning, and the last sunlight in the evening. Relying on solar power off-grid requires that you maximize not only your peak output, but also your hours of “harvesting”, as any significant loads you are going to power overnight, such as refrigeration, will be totally dependent on the energy stored in your battery bank, unless you have a power source other than solar, such as a windmill or water turbine to supplant the solar.Continue reading“PV Power Challenges and Solutions, by Tractorguy”
