Solar Powered Rainwater Project – Completed?

The Solar Powered Rainwater Project began about eight months ago, although one might argue it is the culmination of my rainwater system dreams beginning in 2002.

Weber Piano Action Rebuild – The Circle of Refinement

After the much-needed boost of demonstrating the Weber with rebuilt action at our piano gathering, I was eager to continue. Time to align the hammers so they centered on the strings and shifted correctly when the soto voce pedal (or “soft” pedal, on the left) was pressed.

Solar Powered Rainwater Project – Final Assembly

With all the parts in stock, it was time to assemble the whole Solar Powered Rainwater Project. I cleaned out a space in the garden shed, and added plywood to the wall for attaching the various components. We would be mounting the inverter/charge controller, solar panel combiner/breakers, A/C transfer switch and related wiring.

Solar Powered Rainwater Project – Batteries

You may recall from an earlier post that the Solar Powered Rainwater Project requires substantial battery storage. In our original calculations, we decided we would need 15,796 watt/hours of storage to provide three days of autonomy (or days without sun).

Solar Powered Rainwater Project – The Chinese Connection

It’s been a while since I reported on the Solar Powered Rainwater Project. Since that early-April post, I’ve been gathering the rest of the parts, and we took our annual trip to the Red Power Roundup — this year at the Iowa State Fair in Des Moines. The biggest part of the delay was waiting for the inverter/charge controller. I wasn’t thrilled with the delivery delay on the device, but it turned out well in the end.

Weber Piano Action Rebuild – Keyframe with Refurbished Keys

I’ve been making progress on the Weber Project, but with a trip to New Mexico and various Spring activities, the pace has lagged. We’re back on track though. I mentioned in the last post that more work was needed on the bushings — they were too tight for the keys to move freely in the keyframe.

Solar Power Rainwater Project – Panels and Angles

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

Solar Powered Rainwater Project – to Grid-Tie, or not to Grid-Tie. (that is the question)

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

Solar Powered Rainwater Project – Panels, Batteries and Inverters — Oh My!

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

Weber Piano Project – Keyframe Cleanup

With key bushings installed, it was back to the piano shop. In order to test the work, we would need to try a few keys in the keyframe and see they fit. First though, a little cleanup was in order. … Continue reading
