SOLARTRON Energy Systems Inc ., Amherst, Nova Scotia, Canada has developed the SolarBeam Concentrator which can provide more solar heat (about 44,340 BTU per hour) than conventional hot water and process heat systems at an affordable price. The payback period (after rebates) is only six years, compared with 20+ years for conventional flat panel or 15 years for evacuated tube technology. The SolarBeam Concentrator system is simply the most efficient solar hot water system available. Since it concentrates energy on a focal point using a parabolic mirror, the SolarBeam is 262% more efficient that hot water panels and 98% more efficient than evacuated tube technology. In addition, the SolarBeam concentrator is equipped with a computer-controlled dual-axis tracking system that maximizes solar concentration equivalent to 350 suns, which means more efficiency throughout the day
The SolarBeam uses patent-pending technology to provide 13kW of heat per hour throughout the entireday. “1 SolarBeam can heat 400 gallons from 62 F to 140 F in 5 hours” says Herniak. With the SolarBeam you can make a major impact to reduce green house gas emissions and lessen your dependency on fossil fuels, whether in the form of electricity, natural gas, or oil. Multiple stand-alone systems can generate thousands of kW or BTU required for even the most demanding applications.
In addition, the SolarBeam produces more power during the course of the day compared to other systems because of its patent-pending celestial tracking system. The SolarBeam is able to follow the sun throughout the course of the day, with 100% accuracy.
In applications where the solar hot water system will be installed on a flat roof, a different mounting application is used. The mounting of SolarBeam on the roof is a perfect option for apartment buildings, hotels, offices, grocery stores and retail stores.
The solar hot water system is designed to take advantage of the parabolic curve performance of a reflector which is the most efficient means of collecting solar energy. By utilizing the parabolic curve, the SolarBeam hot water system focuses the sun’s intensity onto the focal point, where the absorber is located. The solar absorber is made of solid aluminum block to maximize the thermal transfer to the poly-glycol fluid. Incredibly, the absorber is very small (10” x 10”) but has the ability to provide 13kW per hour (44,000 BTU).
In summer 2011, SolarTron plans to deliver a photovoltaic module to produce 4 kW/hour of electricity from a single system, using the latest concentrated photovoltaic technology. This module is 10 inches x10 inches and can be added to existing solar hot water systems.
