Logging harvested solar power using $15 Scorpion Board

It’s undeniable that South Africa is experiencing a critical electricity crisis. On the positive side, it’s forcing us to conserve and consider alternative sources of energy. My mom sponsored our household with a cheap Chinese solar panel with battery pack and LED lights to use during load shedding (we live in Cape Town zone 6 and you can find the schedule here). This made me wonder: how much solar power do ...

Arduino Solar Day Night Controller

Introduction This is an Arduino controlled light sensing switching unit. Its main use is to control solar lights to turn on when it is dark outside, but it can work in many more applications. This guide will walk you through every aspect of the building process. Prior knowledge of the Arduino unit is not necessary since the code and schematic have been supplied for you. This project would be fairly complex ...

See-through solar concentrator harvests energy from sunlight

A team of Michigan State University (MSU) researchers has created a transparent solar concentrator able to turn any window (or other sheet of glass, such as the screen for a smartphone) into a photovoltaic solar cell. What makes this development different? The panel is truly transparent. Earlier attempts at building transparent solar cells resulted in panels with tinted glass and/or compromised visibility. ...

Solar-Oriented, Arduino-Powered Clock

This is a clock designed to keep accurate time (independent of atomic or GPS), display local sunrise, sunset and solar noon, and also adjust itself for daylight savings time. I wanted the clock to be easy to use and be flexible. The setting functions are menu-driven, you set each parameter one digit at a time (with live data validation) and you can abandon changes if you want. You can have 12 or 24-hour tim ...

Print-On Polymer Multiplies Solar Output

PORTLAND, Ore. -- Scientists have demonstrated a doubling of the number of electrons produced by carbon-based photovoltaic polymer potentially doubling the efficiency of any solar cell. The process called "singlet fission" produces "identical twin" electrons from a single photon, instead of the normal one, dramatically boosting the theoretical maximum output of solar cells. Instead of loosing energy to heat ...

Arduino Solar Radio

Solar charging, via the panel on the back. * 12 position switch to select channel number * Seek up / seek down controls and 'store' button * RDS display of call sign * Frequency display * Battery voltage display * Solar charging current display The software still needs a bit of attention. Its fine if the signal is good and RDS comes in quickly, but if not, then adjusting the volume or changing channel takes ...
