Solar-photovoltaic arrays seem to get cheaper and more efficient every day, making them increasingly practical in renewable and/or remote power supply applications. Still, the voltage generated by any ...

This device is designed to be a simple, inexpensive ‘comparator’, intended for use in a solar cell power supply setup where a quick ‘too low’ or ‘just right’ voltage indicator is needed. The circuit ...

Researchers in India have developed a new method to operate a solar-plus-storage system in a stable manner under varying operating conditions. They claim that their novel technique enables the ...

When a switching regulator generates the main output voltage, additional regulated outputs may be added using various configurations of coupled inductor or charge-pump circuits. Frequently, the lowest ...

We tested 20 solar generators to find the most versatile devices that can provide emergency backup power and fuel off-grid ...
