In the past we've covered how to turn the inexpensive Ikea Sunnan solar lamp into a solar display case and today we have a hack from electronics manufacturer Voltaic Systems to turn the same lamp into ...

The simplest and easiest way to charge a battery with a solar panel is to connect the panel directly to the battery. Assuming the panel has a diode to prevent energy from flowing through it from the ...

This Low Dropout Voltage (LDO) solar charge controller uses a simple differential amplifier and series P channel MOSFET linear regulator –their compatibility seems like a marriage made in heaven.

This is a simple solar boost converter and voltage limiter circuit that charges a 12V battery from a 6V solar panel. It also demonstrates MPPT (Maximum Power Point Tracking) capability. When we think ...
