Detailed Product Description

What is a Heliostat?

A heliostat is an axis-mounted mirror moved by clockwork or computer to reflect a sunbeam steadily in one direction. It can be considered an electronic sunflower. By tracking the movement of the sun using mirrors, sunlight is redirected along a fixed axis toward a stationary target or solar receiver. Heliostats are gaining in popularity due to their many novel green energy related usages. A heliostat system consists of several mirrors in a secure metallic frame with a computerized control system - proprietary software and a control box that interfaces the heliostat(s) with your PC. Many heliostat customers channel natural light through windows, skylights, atriums, mirrors, to shaded landscape areas, and solar panels that might be obstructed from sunlight (by trees, poles, tall buildings, etc). Each heliostat can be programmed to reflect light to multiple targets; switching between targets takes only a click of your mouse or can be pre-programmed by the software's built-in timer. An array of heliostats can range from 1 to 200 under a single PC control box. Each heliostat reflects about as much visible light as forty 100-watt light bulbs, so one heliostat is very effective for lighting a single room or a small outdoor space. In many ways, the heliostat "harvests" sunlight by redirecting it to a single location or several different locations throughout the days, weeks, and months. In addition to providing natural light, the heliostat system can be used to heat indoor areas and to concentrate solar power (CSP) for energy saving thermal applications.

This device solves problems created by tall structures, trees, utility poles, and poor building designs limit property owners' use and supply of free natural light. Also, customers in the U.S. who use the Empire Exports Heliostat System for thermal applications (e.g. direct space heating or concentrating solar power), may be eligible for various federal and state tax credits and sales tax exemptions. For more information, please visit (the Database of State Incentives for Renewables & Efficiency). Check with your country's government to see if there are programs that pay you back for installing solar.

Heliostat Uses

The cool thing about heliostats is they make the design of a home or office much more flexible and creative, enabling rooms to get heat and light from the sun all daywhether or not directly in the suns path at any particular moment. Other uses include pointing sun to shaded areas for gardening, growing a vegetable garden in the winter. all season greenhouse, into laundry rooms to dry clothes, or toward solar panels on a roof that might otherwise be shaded with trees youd rather not cut down. Heliostats create inviting spaces with energy saving capabilities as well as health benefits.

New York City's Battery Park exemplifies a wonderful and easily achieved use of heliostats. Battery Park is surrounded by several skyscrapers, which would block sunlight at key periods throughout the day, limiting a park's potential to grow and flourish. However, forward thinking architects and designers believed that a park surrounded by several skyscrapers could be an inviting green space. Heliostats are now positioned on the tops of The Verdesian, redirecting ample natural light and in turn making the once perpetually shaded space, with a potential for mold and insect problems into the lively and lush green space attraction it is today; and at the same time preventing mold, bugs, pools of standing water, and other issues associated with poor natural light.

Individual heliostats can be used for direct thermal applications, meaning that sunlight is applied directly to an area or object(s) to be heated, rather than going through a central collector or receiver. For example, heliostats can supplement a buildings heating systems by simply directing sunlight through windows and skylights.

New products like thermal receivers are being developed for intergration a heliostat system for more sophisticated thermal applications. The heliostats reflect concentrated sunlight onto the central receiver or collector ("CSP receiver"), which distributes the heat. Ourr Heliostat Systems are most easily adapted for thermal applications that require low-grade thermal energy (<232°C or 450°F). Oil or steam is the preferred heat transfer medium for applications in the range of 100-232°C (212-450°F). For applications requiring thermal input below 100°C (212°F), water can be used as the heat transfer medium. For applications requiring thermal input higher than 232°C, the system can be customized to increase the concentration of energy.

Direct thermal applications include:

Interior space heating
Swimming pool heating
Drying paint or wood, melting ice dams on roofs, and other miscellaneous direct thermal applications

Concentrating Solar Power (CSP)

The PC-controlled, hand-installable heliostat system supports applications such for concentrating solar power When used with an ancillary product like a CSP receiver, the heliostat or array of heliostats can be used for advanced thermal applications, such as building heating and cooling, desalination, low-temperature industrial processes and electricity generation according to the manufacturer. The system consists of software, a driver box and any number of heliostats. The driver box can control up to 200 heliostats - all individually programmed and controlled with the personal computer. The control software runs in the background, so the computer can be used normally. Rotation of the heliostats is digitally controlled to an accuracy of 0.1 degrees.
