Solar on a Cloudy Day

Yesterday's forecast called for hail just east of Dallas and Paul thought we would be safer here in Cottonwood. Mary spent the day baking, I spent the day reading about our solar system and checking our meters every few hours. Paul was kind enough to drop off a wiring diagram of the system he installed and so I filed that for future reference.

As you can see the day was heavily overcast. I was surprised that our panels were able to collect some energy even without direct sunlight.

While we were in Fort Worth (on Monday) another customer dropped of her trailer for repairs. It is amazing how many women are travelling alone in "Airstream" trailers.

Our Trimetric 2025-A meter showing the amps coming in from the solar panels (don't forget this was in heavily overcast skies). This meter is essential if you plan to use solar power and want to know how many volts or amps are going in or out of your batteries.

Paul watches while we use an hydrometer to measure the specific gravity of each battery cell. This gives us a true reading of the state of charge and health of each battery cell.  If you think Paul looks a little different you are very observant; he shaved last night.

Mary records the data, which gives us a history of our batteries for future reference.

Today we leave for Zavalla. How far we get ................... who knows?
Safe travels and stay in touch.
