Solar Efficiency: It’s Not What You Think, Part 2 of 2.

In Part 1 we started with some conceptual topics, then moved on to the physical hardware that is the cause of inefficiency. In Part 2 we’ll address batteries, then go step by step through a typical system and identify where solar efficiency is compromised. Batteries: The great unknown. Calculating battery… Read more »

Solar Efficiency: It’s Not What You Think, Part 1 of 2

One of my readers asked about inverter efficiency and suggested that it would be helpful to the Off Grid Ham community if I did an article about overall solar efficiency. Since that’s not the first time the question has been raised, I’ll accept the invite. In this two part series… Read more »
