PV and solar power systems convert light into electricity. They are the building blocks of photovoltaic (PV) modules

Alternative power generators produce electricity from renewable energy sources, such as wind, flowing water, solar energy and biomass, which create less environmental damage and pollution than fossil fuels

Three phase uninterruptible power supplies (UPS) are devices that operate in conjunction with existing electrical systems to provide power conditioning, back-up protection and distribution for electronic equipment loads

Electrical power generators transform mechanical energy into electrical energy, typically for backup or emergency power. Generators can produce either AC or DC power and are typically powered by a fuel engine

Photovoltaic cells generate a voltage when radiant energy falls on the boundary between dissimilar substances.

Alternative energy installation services specify and install photovoltaic, wind energy, and other distributed energy production systems for commercial and residential applications.

DC to AC converter chips transfer a DC input into AC power by using switching, inversion, or other technology

Welding machines and joining machines include all manner of devices used for welding, brazing and soldering.

Energy product testing services test, evaluate, and analyze the safety, efficiency and performance of energy storage, power generation, and transmission systems that use conventional, renewable or alternative energy

Induction heaters use an electrical source to drive alternating current (AC) through a coil to heat metal objects.

Calibration and repair services for vibration, acoustic, electrical / electronic test, environmental, dimensional, NDT, analytical, process and other specialty instruments, sensors and related equipment.

Power supplies are devices that produce AC or DC power.  This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters

DC power supplies accept an input power and output the desired form of DC power. Common types of DC power supplies include linear power supplies, switching power supplies, DC-DC converters, and silicon controlled rectifier (SCR) type power supplies

DC to AC inverters are used for converting direct current (DC) into alternating current (AC). They are also known as DC to AC converters

Solar radiation instruments measure the spectral range of radiation, including global solar radiation (sun + sky), net radiation (incoming solar - reflected solar) and the photosynthetic light spectrum
