There are many ways to dispose of those things in life we would like to never see again. One of those things is as old as biology itself, and that is waste generated by the organism (okay, we’ll just say it… feces.) Researchers at the University of Colorado, Boulder have developed what they call the Sol-Char, an off-grid human waste mechanism that uses the power of the sun to turn poop into coal. What sets this apart from other composting toilets is that it uses concentrated light/energy from the sun to essentially incinerate (at temperatures up to 600 degrees Fahrenheit, around 315 Celsius for our overseas friends) the waste to a coal-like product that can be used as agriculture fertilizer or soil amendments.
We recently received an inquiry regarding photoresistors and solar lights. We thought it was an interesting topic, so we decided to share it with you today.
Inquiry: Please help. I have solar garden lights. One clearly has a photoresistor while others do not have a photoresistor. They all turn on at dark, off when there is sun. The model with photoresistor has 2 wires coming from solar cell and two wires coming from photoresistor. Model without visible photoresistor has only two wires coming from solar panel. How does this work without a visible photoresistor. Thank you.
Response: Hello. We checked with one of our test lights and found that the photoresistor was integrated into the solar panel. It was not easily seen on the face of the panel, but once we disassembled the light we were able to determine that this was the case. There was also only one set of wires (black and red) that fed into the solar panel from the circuitry board.
This may or may not be an advantageous placement for the photoresistor. From what we have experienced, it is leaning toward “not”. These lights gave out sooner (after about a year and a half) than other lights, so we no longer carry them on our website. It may just be an engineering matter that is not yet perfected.
Hopefully this information helps with your inquiry. If the light is working, then that is a good thing. If it is not and you are looking to replace/substitute the photoresistor, then it may be best to recycle/discard the light and replace it with a whole new light. Replacing a photoresistor will take some engineering/electrical know-how and may be more trouble than it’s worth.
Thank you and we appreciate your inquiry.

Now, why is all of this important, you may ask. Well, in a nutshell, the photoresistor tells your light when to turn on and off. Turning on and off is also important for your batteries. An improperly-working photoresistor (also known as a photocell) may bypass the “off” mode and have your lights “on” constantly. This means that the battery is being used during the day and will not retain enough charge in the night to cast light through the darkness as intended. In the worst-case scenario, a photoresistor that doesn’t work at all may not “tell” your lights to go on at night, leaving you frustrated and disenchanted with the whole thing.
So, when your solar lights aren’t working properly (or at all), a little troubleshooting may reveal that the photoresistor is bad. In this case, it is best to replace the light (if under warranty) or to buy a new one altogether. In most cases, the photoresistor will work properly and the culprit may be a bad battery or that the solar panel isn’t getting enough sunlight during the day.
One of our new lights has what we can determine is one of the most efficient when it comes to circuitry, solar collection and as related to this post, photoresistors. The tiffany-style mosaic glass solar light is top of the charts. We charged it for one day and it was able to light up indoors for two nights (skipping the second day of charging) with no problem. And, it is quite attractive and versatile (not many lights can be put indoors on table tops.) It’s worth checking out.
Enjoy your day (and night) fellow solar lighters.
