Power Towers:

The Solar Power Tower generates 15 to 100+ MW of electrical power by converting the sun's thermal energy into electricity at competitive prices for renewable energy. Several plants can be located together to provide significant centralized power generation.
The power tower operates by focusing the sun's energy with hundreds of mirrors, called heliostats, onto a heat receiver located on top of a tall tower. This receiver collects the concentrated solar power and elevates the temperature of a molten salt by several hundred degrees. The heated molten salt is pumped to a storage tank, then through a heat exchanger where water is converted to steam to drive a conventional electrical turbine generator. During periods of peak power demand, darkness or cloud cover the stored molten salt continues to feed the energy needs to generate electricity
The heart of the solar power tower plant, called the molten salt receiver system, provides the thermal generation capability required to deliver pollution-free power without burning fossil fuels. This technology has been successfully demonstrated and is ready for commercialization.

Dish Systems:

Solar Dish's are shaped much like large satellite dishes and covered with curved mirrors. These solar dishes are programmed to always face the sun and focus that energy on a collector in much the same way that a satellite dish focuses radio waves on a tuner. This collector is connected to an engine which uses the thermal power generated by the focused solar energy to heat liquid hydrogen in a closed-loop system. The expanding hydrogen gas creates a pressure wave on the pistons of the engine which spins an electric motor creating electricity with no fuel cost or pollution. This technology is referred to as solar thermal or concentrating solar power.

Trough Systems:

A parabolic trough is a type of solar thermal collector. It is constructed as a long parabolic mirror (usually coated silver or polished aluminum) with a Dewar tube running its length at the focal point. Sunlight is reflected by the mirror and concentrated on the Dewar tube. The trough is usually aligned on a north-south axis, and rotated to track the sun. Heat transfer fluid (usually oil) runs through the tube to absorb heat from the concentrated sunlight. The heat transfer fluid is then used to heat steam in a standard turbine generator. The process is economical and, for heating the pipe, thermal efficiency ranges from 60-80%.
Because current commercial plants utilizing parabolic troughs are hybrids (fossil fuels are used during night hours) and include cooling stations, condensers, accumulators and other things besides the actual solar collectors, the kWh per square meter of space ranges enormously.
The largest operational solar power system at present is of this type. Named SEGS, it is located at Kramer Junction in California, USA.

Ring Arrays:

The optical design of the Ring Array is based on the multi-imaging approach, which suggests shaping and superpositioning of multiple source images/caustics in the common focal zone by a set of parabolic rings or bands. Such a technical concept possesses the two main advantages: very high concentration level, which can reach half of the thermodynamical limit, and rear disposition of the focal zone relatively far away from the reflecting elements. These advantages allow to apply parabolic blind-reflecting concentrators as a more promising solar optics for Stirling or photovoltaic power systems, as well as for various "immediate" thermal technologies and solar architecture of small individual cottages and social buildings.

Slat Arrays:

This proof-of-concept R&D project is aimed at the development of a new concentrator photovoltaic (CPV) module based on a novel reflective lens concept. It exploits and further develops our proprietary slat-array linear concentrator design to provide 200–300% better concentration than Fresnel lenses as well as uniform illumination of solar cells.
