Ground Solar, Part IV, The Inverter

In previous articles here, here, and here, we’ve been discussing our off-grid solar power system we used during Hurricane Matthew. We also gave an overview of solar panel and lead-acid battery principles. While there is much more to discuss regarding batteries, including alternative battery technologies, let’s skip ahead to the inverter, which is the tip […]

Introducing Caveman Chemistry

It’s the holiday season at the Old School, and this means it is finally cool enough for those chemistry projects we’ve been looking forward to all year long, including those best done over a nice fire in the wood stove. Our favorite book to guide these experiments is Caveman Chemistry, by Dr. Kevin Dunn. Dr. […]

Off-Grid Lead Acid Battery Principles

We’ve been dedicating several posts to building an off-grid energy system with solar panels. Any off-grid energy system, especially solar, is best operated with batteries to store energy, unless you plan on making a generator available 24/7 to fill in the gaps. There are many available battery technologies, and eventually we’ll review many of these. […]

Offers 7 Nov 2016

Saturday’s post about chargers mentioned that our sponsor SoftBaugh might be able to get pricing that would beat Amazon pricing for some items. Here are the latest quotes SoftBaugh is able to provide (in all cases, ground shipping to US locations is included): Midnite Solar Classic Lite 150 MPPT Charge Controller: SoftBaugh can offer this […]

Ground Solar, Part III, The Charger

In Part I of this series, we provided an overview of the solar power system we deployed on the ground to keep our freezer and refrigerators running after Hurricane Matthew. In Part II, we discussed the combiner, an essential element that is often overlooked. Along the way, we discussed the principles of solar panels as […]

Ground Solar, Part II, The Combiner

In the previous ground solar post, we described deploying a solar power system after Hurricane Matthew to keep our freezers and refrigerators running. In the post on solar panel principles, we discussed important issues to consider when selecting solar panels. Once you’ve selected a solar panel model to create your solar power array, it is […]
