Solar-powered tricycles are enabling mobility for rural communities in Zimbabwe.

The e-tricycles, also named "Hambas" in the local language, are custom-built and includes solar-charged battery packs.

Question: Why don't have panels on the back to extend their life?

I know you can't charge a phone just from a tiny solar panel, but as an extension? Over the course of an entire day, surely it would add a few percent.

San Francisco based Sunrun Inc expects to install enough ☀️ panels on U.S 🇺🇸 homes this year to produce as much energy (>1 gigawatt) as a power plant.

Happy International SUN Day!

The idea behind this day was to ‘draw attention to sustainable energy sources and their use for the solutions of ecological problems’

"Studies from all over the world have shown increase when the crops are partially shaded with panels. These yield increases are possible because of the created underneath the solar panels that conserves and protects plants from excess sun, wind, hail and soil erosion. This makes more food per acre, and could help bring down food prices."

is now producing more at this time of year than it consumes in total between 12pm and 3pm. (the big issue for utilities is the steep curve at the end of the day when solar goes offline, and they have to ramp up other production sources... since very small amounts of that solar energy is able to be stored).

I wonder what design changes would need to happen if we moved the grid from "instantaneous gratification" to "feast or famine"?

e.g., workloads happen when they happen.

I know not everything can opportunistically sip from a solar cell, and AC and clothes washers and microwaves people all seem to want to run right now.

Last week Customs updated its Uyghur Forced Labor Prevention Act (UFLPA) enforcement dashboard. A few notable observations:

  1. Customs is obfuscating what they are detaining. The category "electronics" includes & a convo I had with an enforcement official revealed that detentions of non-solar electronic items were "not statistically significant."

  2. Enforcement is overwhelmingly directed at "electronics" (solar) at 87% (by value) of detentions. /1 (thread)

Most of the fence around my AC in the side yard was trash.

So I figured instead of replacing the fence with another fence, I'd replace it with a very shallow garden shed / closet for hand tools.

Mock up of the final system with a EPEver 20A tracer MPPT solar controller and a 50Ah LiFePO4 battery.

DeWalt 12V charger and lots of USB ports as the load.

Now I just need to nicely mount all of this on shelves... which don't exist yet, so I need to build shelves.
