It’s been a tough couple of years. The last two years have seen below-normal rainfall. While not unusual in the Hill Country, they have been remarkable for the depth and severity of the Texas drought. During the years ending September 2022 and 2023 we measured just 11.75 and 10.65 inches respectively. That compares with an average rainfall of between 30 and 35 inches.

Major equipment purchase done, it’s time to think about the installation. The solar panels will be arriving in a day or two, and I plan to install them right away. Solar panels produce maximum power when the sun is perpendicular to … Continue reading →
Previously, we discussed the amount of power needed, and how that determines the size of the solar array. We also mentioned Days of Autonomy and how that informs battery storage. Now for Charge Controllers and Inverters — the brains that tie everything together. … Continue reading →
In a previous Project post, we determined our power needs – 1300 watt-hours per day to pump water. Now we can calculate the battery bank capacity, solar panel wattage, and inverter capacity needed for our installation. Let’s start with the panel … Continue reading →
If you’ve been following along, you’ve noticed several solar-powered projects here at Roy Creek Ranch. From a simple system to “top-up” the storage battery in the Teardrop trailer and upgrading it to make an off-grid camper, to powering my amateur radio … Continue reading →
We moved to the Ranch in December of 1996. Everything was brand new and shiny. The well had gone in a few months before as part of building the house, so by now it was about 15 years old. Most … Continue reading →
