Energy Harvesting Solar Panels

Photovoltaic solar cells provide the most common alternative energy.

Energy harvesting solar panels.

This is the most widely adopted method of harvesting solar energy today. These panels which range in size from a few square centimeters to a few square meters are constructed from many pv cells arranged in an intricate matrix. Analog devices offers a wide range of ultra low power ics for energy harvesting applications. Countless articles and studies have been done on maximum power point tracking mppt algorithms to extract as much energy from a solar source as possible.

Most solar panels convert around 15 of the sun s energy into electricity. You can t just throw together a solar cell harvesting ic and rechargeable battery and say done perhaps you need a more complicated circuit with a supercapacitor for example. One way of measuring the efficiency of solar panels is to calculate the percentage of the solar energy that a panel converts into electricity. Power management products that convert energy from vibration piezoelectric photovoltaic solar and thermal tec teg thermopiles thermocouples sources provide high efficiency conversion to regulated voltages or to charge batteries and super capacit.

More experimental photovoltaic panels like concentrating solar panels can convert 40 of incident solar energy into electricity.
