A team from Caltech (California Institute of Technology) ETH Zurich and the Paul Scherrer Institute could assist the thermo-chemical production of fuels. In a paper published in the journal Science, the researchers claim that fuel can be generated over 500 cycles. Solar to fuel efficiencies of 0.7-0.8 per cent were achieved. [via]

This device allows solar cell arrays to be connected to either conventional lead-acid, sealed lead-acid, or lithium storage batteries without fear of overcharging. It allows two different electrical loads to be driven from the batteries at two different charge states to maximise power usage efficiency.

This project is a solar irradiance meter based on TSL230R Light-to-Frequency converter and Amicus 18F25K20.
This chip features an “electronic iris” to facilitate measurements over a wide range of intensities. The photo sensor may be enabled in 3 stages to measure from near darkness (the glow of a computer monitor) to full-intensity sunlight. The output of the sensor is a pulse stream whose frequency is proportional to irradiance.

This project shows how to build a 63W solar panel using plain materials. It will guide you through everything from building the frame to soldering the solar cells. The frame is build of plywood and solar cells is better to be soldered using a low wattage soldering iron. Finally you add the plexiglass and your panel is ready. Check construction details on the link below.

This project is used for charging sealed lead-acid batteries with a solar panel in small and portable applications. The charger will stop charging once a pre-set voltage (temperature compensated) has been reached, and resume charging when the voltage has dropped off. The load is disconnected when the battery voltage drops below 11V and reconnected when it gets back to 12.5V.
