"we offer solar pool heater that reduces swimming pool heating. They're cost competitive with both gas and heat pump pool heaters, and they have very low annual operating costs. Actually, solar pool heating is the most cost-effective use of solar energy in many climates. How it works: • a solar collector: the device through which pool water is circulated to be heated by the sun • a filter: removes debris before water is pumped through the collector • a pump: circulates water through the filter and collector and back to the pool • a flow control valve: automatic or manual device that diverts pool water through the solar collector. Pool water is pumped through the filter and then through the solar collector, where it is heated before it is returned to the pool. In hot climates, the collector can also be used to cool the pool during peak summer months by circulating the water through the collector at night. Some systems include sensors and an automatic or manual valve to divert water through the collector when the collector temperature is sufficiently greater than the pool temperature. When the collector temperature is similar to the pool temperature, filtered water simply bypasses the collector and is returned to the pool.

"slt energy offers solar air conditioners at very low operating and maintenance costs, and consumes little or no electrical energy. The only parts that use any electricity are low amp fan motors, control boards, and small pumps that move the thermal transfer fluid from the collectors to the chiller and then back up to the collectors. the solar air conditioner is powered by solar energy collected in the evacuated tube solar thermal panels. The thermal energy collected is then delivered to the solar powered chiller using a propylene glycol heat transfer solution and a simple but carefully designed piping system. "

Working Principle In parabolic trough collector, long, Parabolic mirrors focus the rays of the sun into an absorber pipe. The mirrors track the sun on one linear axis from north to south during the day. The pipe is seated above the mirror in the centre along the focal line and has a heat-absorbent medium running in it. The collector is generally composed of one bent glass mirror, with either silver or aluminium coated on the backside of the glass. The glass is about 4mm thick and low in iron, maximizing the reflectance of incoming sunlight. Parabolic trough collectors are a low cost implementation of concentrated solar power technology that focuses incident sunlight onto a tube filled with a heat transfer fluid. The efficiency and cost of the parabolic trough collector designs is influenced by structural stiffness, choice of materials, assembly tolerances, mirror cleanliness and wear. ADVANTAGES: 1. The working Fluid can achieve higher temperatures in a concentrator system when compared with another evacuated tube system of the same solar-energy collecting surface. This means that a higher thermodynamic efficiency can be achieved. 2. The thermal efficiency is greater because of the small heat-loss area relative to the receiver area. 3. Reflecting surface requires less material and is structurally simpler than other collector. For a concentrating collector, the cost per unit area of the solar collecting surface is therefore less than that of another collector. 4. Owing to the relatively small area of receiver per unit of collected solar energy, selective surface treatment and vacuum insulation to reduce heat losses and improve the collector efficiency are often economically viable.

We are offering non pressurized solar water heater. "non-pressurized compact solar water heater is a kind of solar water heating system that solar collector and storage water tank are connected together, water tank on the top and collector panel on the bottom. It relies on the natural circulation of waters between the collector and the water tank. As water in the vacuum tubes is heated, it rises naturally into the tank, while cool water in the tank flows down to the bottom of the vacuum tubes, causing circulation throughout the system. It moves household water or a heat-transfer fluid through the system without pumps. It is a simple and safe solution to get heat power from the sun. material: • water tank: sus304-2b food grade stainless steel • external shell: nacre white armor plate • insulation layer: 50-60mm polyurethane foamed • structure: electric heater connecter, water inlet and outlet holes, and exhaust hole • frame: galvanized sheet with metal baking varnish • best angle: 45° • seal: macromolecule silicone rubber • vacuum tubes: borosilicate glass, with magnetron sputtering aluminum nitride absorbing coating • specification of vacuum tubes( dia.*length): 47*1500mm; 58*1800mm "
