Unitronic is planning to present a wireless solar-powered sensor module for the continuous monitoring of carbon monoxide (CO) concentration in buildings and in industrial applications at the upcoming SENSOR+TEST 2011 in Nuremberg, Germany.
The core of the Unitronic Solar CO Sensor Module (USCSM) is an innovative electrochemical carbon monoxide sensor with a standard AA battery form factor, developed by Figaro, which meets the specifications of EN 50291 and VDI 2053, and a STM 300 programmable, bidirectional wireless sensor module for 315/868 MHz from EnOcean.

We propose to build a solar battery charger that will charge a variety of batteries: NiMH, NiCd, Li-ion, lead acid. Although there are solar battery chargers on the market, most are only for one application: cell phone, NiMH batteries, etc. Our charger will have the user input the battery type, capacity, and voltage. It will display the charge status and incorporate various safety systems, including temperature monitoring and battery polarity checking.

The goal of this project is to use LEDs to produce a system capable of simulating solar conditions for the purpose of testing solar panels. Features of the system include adjustments in intensity and spectrum, simulation of spectral shifts that occur during sunrise and sunset, simulation of some weather conditions, the ability to adjust the angle of incidence of the light on the panel, and computer interface for quick, easy adjustments and control. A system to implement automatic time of day adjustments would bring all of the above together into one process.

If living plants were pitted against man-made solar energy to determine which is more efficient at harvesting sunlight, which would you choose to come out on top: plant leaves or solar cells?
Scientists recently compared the efficiencies of real photosynthesis in plants to that of using man-made solar cells to harvest the energy of the sun. The results showed that even under ideal conditions, the difference was two to three times better for one over the other. Which would you bet on winning?

Hello there. You’ve probably found this Instructable to gather ideas about making a portable solar power supply yourself. I’ve always been interested in electronics with this project being my latest idea to come wandering out of my head, why not make a portable box on wheels, that I can plug basically anything into, thats powered by the sun? So therefore I thought I’d share this Instructable with the rest of the world.

Jordan McRae was interested in integrating solar energy into his projects and professional designs. After months of experimentation he came up with the design for B-Squares™. [via]
As he describes the project:
B-Squares is a 3D modular electronics system with an emphasis on (but not limited to) solar power and expandable energy storage. Each Square has a magnetic contact on each of the corners which allows the Squares to easily snap together without wires. The magnetic contacts are also used to transmit electric signals between the Squares. This design allows users to quickly assemble Squares into arrays, with power flowing through the array via the corner contact, without wiring or soldering. Also, due to the use of multiple magnetic contacts on each Square, the overall circuit of the array can quickly be changed simply by rotating one of the Squares – for instance, the color of the LED Square can change with a flip or a rotation.
To date, the project includes squares for a 0.25 W solar panel, a AAA battery power pack and multi-color LEDs. Other squares accommodate iPhone/iPod docking as well as an Arduino square and a proto-square.

If a new development from labs at MIT pans out as expected, someday the entire surface area of a building’s windows could be used to generate electricity — without interfering with the ability to see through them.
The key technology is a photovoltaic cell based on organic molecules, which harnesses the energy of infrared light while allowing visible light to pass through. Coated onto a pane of standard window glass, it could provide power for lights and other devices, and would lower installation costs by taking advantage of existing window structures. [via]

As the solar power industry grows, so must too sun tracking circuitry. This project gives a short but sweet example of how to build a system for sun-tracking. It’s not professional grade, but it is a great place to start if you’re looking to build your own sun-tracking solar panel.

When I got into electrical circuits and solar power the first thing I wanted to do was build a little solar powered battery charger. Only I had a heck of a time trying to find a simple and strait forward guide to doing this.
