Solar Hot Water Panels Year 1 Data, sort of — Lab Note 1.08

Last year I built prototype solar panels and summarized the preliminary data gathered in some test runs (see this project’s archive here). I’ve been collecting performance data over the last year and am now ready to present the results. Data Collection The data for this analysis comes from three temperature loggers (Elitech RC-4, P.S., we … More Solar Hot Water Panels Year 1 Data, sort of — Lab Note 1.08

Grow Your Own — Part III: Rules for the Experiment

We should define the parameters under which we’ll be carrying out this simulation. You can read about the inspiration and overall idea for this experiment in Part I and the chronological outline in Part II. Here we’ll drill down on exactly what we’ll be doing. 1. We will concentrate our growing efforts on about half … More Grow Your Own — Part III: Rules for the Experiment

Grow Your Own — Part I: What if Fossil Fuels Disappeared?

What if fossil fuels disappeared? That is the premise of the Low Technology Institute and the question is not rhetorical. Fossil fuels will stop being used, whether it is tomorrow or in a few decades. At some point we will no longer be using coal, natural gas, or petroleum for our main energy sources. Perhaps … More Grow Your Own — Part I: What if Fossil Fuels Disappeared?

The Institute is Getting Solar Panels — Part IV: Installation

Avid readers will notice that we haven’t been posting much over the last month. That’s because every free moment has been given over to installing our solar panels (see the earlier posts here). Here I’ll recap the physical installation of the panels and other components. In the next post, we’ll go through how we ended … More The Institute is Getting Solar Panels — Part IV: Installation

The Institute is Getting Solar Panels — Part III: System Layout

We’ve been chronicling our addition of solar panels (see them all here). Today we’re going to go through the layout and electrical diagrams of the system. The Layout The panels will be mounted on the back of our garage. This is for a few reasons. First, our house’s roof slopes west–east while the garage is … More The Institute is Getting Solar Panels — Part III: System Layout
