Gulf Stream Solar Kits for a Medium Family (3 to 4 people) – Medium Family – Zone 2 Solar Kit. Click on picture for more info and order.

The Solar Collector The solar collector is made up of several vacuum insulated glass tubes that absorb the sun’s rays. It contains a double tube design with intricate layers of borosilicate glass, aluminum, solar filament, and copper pipes. The unit works in such a way that the glass allows light in, connecting with the solar filament yet, the insulation prevents the heat/energy (just recently captured) from being released. Specifically, it absorbs at a rate of 93% but it has a heat loss of less than 6%. The glass tubes are sealed creating a smooth, nearly seamless casing. Borosilicate glass was selected not only due to its strength but also the ability to withstand warping (in either high or low temperatures). The solar collector frame is made of sturdy anodized aluminum and specifically designed to match and hold the 15, 20 or 30 tube collector units. The adjustable frame can be mounted anywhere from a 23 degree angle to a 46 degree angle. Depending on your solar zone and which way the back of your home is situated, the angle of your solar collector may be an important factor in obtaining the optimal amount of light. Back-Up Heater by Gulf Stream A back-up heater makes sure you have hot water instantly. This 9kw back-up heater has the most accurate wattage to match the needs of a medium family. What is most unique about this particular back-up unit is that it is flow sensitive. In other words, if hot water from the solar collectors isn’t available (i.e. a dreary day), the back-up will heat only what you use not the entire tank. This flow sensing back-up heater is the latest development in solar technology, but most importantly one that saves you more money. Control Panel If the circulating pump is the heart of the system then, the control panel is the brain . It regulates the temperature sensors and activates thecirculating pump to go on. This small electrical unit can be mounted on the wall and used to control the system as the homeowner dictates.

Scientists develop new types of solar collectors in plastic construction

Scientists at the Johannes Kepler University (JKU) Linz have taken a major project for the further development of solar thermal technologies on land
You will develop novel collector systems in plastic construction, the existing functional and efficient than they are. This is the worldwide leader in Austria in the field of solar thermal energy further and an essential contribution to the dissemination of renewable energy technologies and to reduce greenhouse gas emissions are made. Funding for the € 5.1 million project on the Austrian Research Promotion Agency (FFG) of research and technology program NEW ENERGY 2020 of the Climate and Energy Fund.
In the networking of plastic and solar energy research offers great potential for the advancement of technologies in the field of solar thermal energy, ie the conversion of solar energy into usable heat energy. Thermal collectors and collector systems are currently consuming and costly manufactured from a variety of different materials. With the use of polymer materials, solar thermal systems functional, visually attractive and more economical, which would have a positive effect on their market penetration.
Basic and industrial research for new generation of collectors
JKU-scientists will develop the project “Solar Thermal Systems Engineering Polymer (Solpol)” novelty collector systems in plastic construction. To achieve this goal, the research project was divided into two complementary projects. In the first part, which is designed as a basic research project, the scientific and methodological basis for the development of novel thermal collector systems be put in plastic construction and estimated the ecological and economic consequences for global market penetration. The second part deals with the industrial research to develop new polymer materials and the resulting manufactured panels and components.
The aim of the entire research project is one part to strengthen the global leadership of Austria in the field of solar thermal continue to make the other a substantial contribution to the dissemination of renewable energy technologies to reduce greenhouse gas emissions.
The four-year, is over five million euros, the project by the Board of the Institute of Polymer Materials and testing of the JKU, Prof. Reinhold W. Lang, coordinates. The project consortium consists of nine academic partners (in addition to several other institutes of the Johannes Kepler University in the field of plastics engineering and polymer chemistry are the Art University Linz, University of Innsbruck and the Austrian Institute for Economic Research – WIFO – involved) and ten corporate partners – companies such as Borealis, angels, Greiner , Kekelit or Lenzing. For Prof. Lang is with this project, a first major step towards a new market segment created for use in plastics, the extraordinarily high growth has potential. “Like other areas will create only through the increased use of plastics in solar technology that conditions such as high functionality, variety of design and cost reductions that are necessary for the widespread use of these technologies.”
JKU-rector Richard Hagelauer added: “We are naturally pleased and proud that it has been trying to get the largest project in an international tender process evaluated at the JKU. We are these activities in the field of plastics technology and alternative energy future, to expand in any case even further. “

Energy

Hartwig Langbein of Struth-Helmershof will continue to use the power of the sun even more
Struth-Helmershof – “Until now we have the power of the sun

still not properly used, “says Hartwig Langbein almost as an aside. A view of the roof of his house and for heating in the basement shows, however, that the Struthers has discovered the sun’s energy for itself long ago.

He may even refer to considerable success. This brought him to the end of 2009, the energy value price of the district Schmalkalden-Meiningen. So that the owner of a metal processing company had not expected. We heard about the competition until the last minute and quickly filled out the documents still remembers the trader. Now it the price of the district for his complex, impeccably synchronized, heat pumps, solar thermal heating system has been awarded.

Was actually created through close cooperation with the Trusetaler consultant for alternative thermal technologies and environmental winner of the state of Thuringia in 1997, Stefan Wolf, and the local heating contractor Chris Klein as a collective work, says host Hartwig Langbein, the award more significant.

Stark put it simply, the inventor of the workings of a solar thermal plant with a heat pump and a large memory are linked. The basic problem alternatively derived from solar power energy is its storage.

When the PV power is immediately fed into the public power grid. are solar thermal process heat energy “stored” on site at the customer must, however, described Stefan Wolf. So they built in the grounds of Hartwig Langbein next to the house is a large underground tank which stores the heat. The insulation is about 60 centimeters thick. It has a capacity of 12 000 liters. The water contained therein is heated by the 45-square-foot solar thermal system.

From the roof of the house from the heated water flows from the sun at appropriate temperatures in the storage belonging to the plant as well as directly to the heat pump. Down their temperatures – these changes cover a wide array installed sensor – gets the system automatically “replenishment” of the solar system.

Has exhausted its potential, does the heat pump into the action. The solar energy stored in mass storage is in summer and winter, day and night, used at a reasonable heating. In the warmer season usually extends the power of the solar thermal plant alone.

The thus permanently recovered from solar power energy will heat the house long leg in the heating and water heating in their use. Since September last year, the system operates in the described association.

It is the inventor team Langbein far from being at the end of the savings screw. One could, for example, the use temperature of the solar thermal collectors lowered even further. Thus, the heat energy of the solar thermal plant not only at ten degrees is obtained from the solar collectors, but, even more efficient, even at temperatures just above freezing. What sounds easy in theory and on the plan is still clearly looks, in practice, a technically complex network of circuits. Their condition is indicated by a number of data points collected continuously and analyzed. Limits are reached, the complex system works independently again until enough heat is present. “We have the expectation that about 70 to 80 percent of the current energy source to save oil,” says Langbein the objective of the investment. About a third of the necessary amount, he received a grant from various funding programs.

Saving effect is even higher

Planner Stefan Wolf draws attention to the fact that this plant is unique with its components. She is a model for how invested the existing building stock later, so that alternative energies can be obtained under practical conditions and stored. “The trend goes into the thermal unit in order to ensure self-sufficiency,” he describes the long-term economically and ecologically sensible objective in the face of climate change.

Given this massive old buildings it is a great challenge to find energy solutions that can be retrofitted as a long-leg home. The existing plant Stefan Wolf describes as “the first steps”. The innovative approach of this solar-thermal heat pump heating system was considered by the district as a forward-looking and honored with the Energy Saving Award 2009.

When the bill comes up, Langbein hopes that his willingness to invest in about ten to twelve years, if not earlier by energy prices, payback. Then the savings would be even greater. Such systems usually have a very long lifetime, exceeding 30 years. eh

Tube collector of Consolar in eco-test on top

Consolar tube collector 12 CI CI awarded top marks in the current eco-test / distinction “very good” for solar coverage rate of Consolar-system

SOLUS II solar collector tube with 12 CI CI Consolar
(Business Wire) Frankfurt am Main, 06.10.2010, Consolar The solar technology is also the latest comparison test of the consumer magazine Oeko-Test (Edition 10/2010) at the top: How was the collector tube 12 CI CI Consolar of the top rating of “very good” for its outstanding performance. Of all 17 tested solar Consolar got the system is rated “very good” for the solar cover. Despite the very small builders friendly collector of 10.6 square Consolar the system achieved a 28 percent, the second highest solar coverage rate in the test. The only plant with a 30 percent coverage rate requires a nearly 50 percent larger roof area than the Consolar system. Consolar thus combines maximum power and performance with comprehensive architectural requirements. The high efficiency of the system makes it possible to implement even on limited roof surfaces, a particularly environmentally friendly plant, large quantities of oil or gas and thus CO2 saving.

Because of the particularly high efficiency of the solar system Consolar for use on the first zero-emission research station “Princess Elizabeth” was selected in the Antarctic. Since early 2009, the plant, the polar station powered reliably under extreme conditions of heat.

Tube collectors for them in winter and in the transitional period, a much higher yield than flat plate collector systems. An efficient solar system does require a memory efficient collectors with very low heat losses. This is ensured in the Antarctic and in the eco-test employed by an innovative combination tank insulation. The SOLUS memory of Consolar were honored as the first steel storage with the environmental label “Blauer Engel”.
