The Sun pulse, a innovative water pump using solar concentrator and stirling engine. At the front of the pump is a solar collector; this reflects sunlight towards the middle where it heats up the front of a Stirling Engine. Sunvention's unique design of Stirling engine uses air at atmospheric pressure as the working fluid, and pulses at a slow 30-60 times per minute. The pump can be attached to a rotary pump, or as shown, connected to a hydraulic cylinder.

eSolar designs and develops Concentrating Solar Power (CSP) projects that start at 46MW and are scalable to any size. eSolar power plant technology utilizes small, flat mirrors which track the sun with high precision and reflect the sun's heat to a tower-mounted receiver, which boils water to create steam. This steam powers a traditional turbine and generator to produce electricity.

SkyFuel, Inc. is a solar thermal power technology and service provider founded in 2007. SkyFuel solar collectors harness solar radiation to produce steam for electricity generation and industrial applications. The Company is a leading supplier of utility-scale concentrating solar power (CSP) systems. SkyFuel currently offers an advanced, glass-free parabolic trough solar thermal collector, called the SkyTrough®.

Sopogy pioneered Micro-Scaled Concentrating Solar Power or "MicroCSP" technologies.  Sopogy's MicroCSP systems cost the same to install conventional Photovoltaic solar systems but increase the amount of energy generated bringing better investment returns to our customers.  MicroCSP uses concentrating mirrors with optics, low cost thermal storage, sun tracking, and a affordable systems installation technique to keep the costs down while delivering a quick payback.  

Solar Millennium is specialised in parabolic trough power plants, a proven and future-oriented technology, in which the Group holds a globally leading position. Besides the three Andasol projects in Spain, a parabolic trough power plant is being built in Egypt . Various further projects with an overall capacity of more than 2,000 Megawatts worldwide are in the planning phase with focus on Spain, USA, China and North-Africa. In the future, solar thermal power plants in the south will contribute to Central Europe`s electricity supply.

SolFocus has developed leading concentrator photovoltaic (CPV) technology which combines high-efficiency solar cells (approaching 40%) and advanced optics to provide solar energy solutions which are scalable, dependable and capable of delivering on the promise of clean, low-cost, renewable energy.

Concentrix Solar GmbH was founded in 2005 as a spin-off company of Fraunhofer Institute for Solar Energy Systems. The company is located in Freiburg in Breisgau. Concentrix Solar further developed the Concentrator PV technology generated from many years of research work at Fraunhofer ISE and brought it from the laboratory to market ready products and advanced it into series production. Under the name FLATCON ® , we offer complete, turnkey concentrator photovoltaic power plants on the commercial level.

From its founding in 2001, Energy Innovations believed in the promise of concentrated solar. Today we stand ready to realize that promise. With the introduction of our new Sunflower HCPV solution, we have harnessed the power of 1,200 suns to achieve an astounding 29% module efficiency. But we didn't stop there — with our holistic approach, we also created the world's simplest and lowest-cost HCPV solution to install.

Green and Gold's solar strategy is to dramatically exceed the cost effectiveness of existing PV flat panels through focused innovations in both the effective collection of solar energy (peak kWs) and the generation of maximum annual electric power (kWhs). To execute this program, our design and development teams worked to create the innovative and ground breaking "SunCube™". 

Our inflated, balloon-shaped concentrators are key to Cool Earth's innovative design. When inflated with air, the concentrator naturally forms a shape that focuses or concentrates sunlight onto a PV cell placed at the focal point. This means we need fewer cells to produce a lot more electricity. In fact, a single cell in our concentrator generates about 300 to 400 times the electricity of a cell without a concentrator.

Sol3g is one of the first companies at world-wide level in commercializing HCPV systems. The company centers its activity in the consultancy, investigation, manufacture and commercialization of third generation photovoltaic systems, particularly specialized in high concentration systems, non-imaging optics and advanced intelligent electro-mechanical tracking and control systems.

The Chromasun Micro-Concentrator is a high performance solar collector that uses the same technology as utility scale solar systems, except now in a much smaller package. It has been designed purposely for rooftop integration. The MCT is low profile, lightweight and has no external moving parts so it’s simple to mount and easy to maintain. Using a 25X Fresnel reflector optic the MCT generates temperatures up to 400°F (200°C).

All HelioFocus-developed solar applications use the same source of solar energy source: the dish, receiver, and heat logistics elements are used identically for the different solutions and applications. This configuration enables high commonality in hardware, achieving better cost values in high volume manufacturing. By combining several dishes in a branch, or by having a large-scale dish field configuration, thermal output for large scale consumers can be provided.

The Sunflower Home Heliostat is a completely stand-alone consumer class heliostat. It is fully solar powered and it independently recognizes and tracks the Sun with its onboard computer and sensors. The Sunflower is easy to set-up and requires little maintenance. It requires only a Phillips head screw driver to assemble.

NextEra Energy Resources operates and partially owns the plants located at Kramer Junction and Harper Lake.

Cleaning a heliostat mirror. As can be seen, considerable effort may be required to clean the mirror surface.

Solar Tower technology at the Solar Research Facilities of the Weizmann Institute of Science (WIS). A major feature of the Unit is a SolarPower Tower containing a field of 64 large, multi-faceted mirrors (heliostats), each measuring 7 X 8 meters. Each heliostat tracks the movement of the sun independently and reflects its light onto a selected target on a 54-meter high tower.

Concentrating solar power (CSP) is a form of energy production technology that concentrates large amounts of solar energy onto a small area. Here, the energy density is much higher than that available from just beam sunshine and the efficiencies of its conversion to useful energy (ie electricity or steam) is much higher. There are three main types of CSP including direct intercept dishes, solar troughs and solar towers. Some newcomers to the field include, for example, the Compact Linear Freznel Reflectors. Solarsphere technology combines elements of direct intercept dishes with solar towers and does this with a design philosophy and materials that potentially permit the units to be produced large and inexpensively.
