Tsinghua Solar Systems Ltd products

JB Series solar water heaters are Close-coupled solar water systems of all-glass evacuated tubular collector with water-in-glass manifold, which are ideal for use in small units, houses and other applications where cheap, reliable hot water supply is required. JB series solar water heaters can be used together with the auxiliary electric boost, thus providing hot water even in the low-radiance day. JB series are available in several sizes, depending on your hot water requirements.

SLR series is an all-glass evacuated tubular collector with heat pipes. One or more pieces SLR series collector panel can be installed in serial or parallel, and the module can be mounted on roof, façade and balcony.

Height: 950mm Solar panel: 2.0Wp Battery: 6V4Ah(maintenance-free lead acid battery) Light source: super-bright LED Controller: solar special intelligent controller Material: stainless steel Light color: white, yellow or multicolor Working time: 12h/day, 5-7 overcast days Environment temperature: -20℃～+65℃ Packing size(mm): 310*310*1055

Developed as per the national standard All-glass Vacuum Solar Collector Tube, the hemisphere emission ratio detector can carry out detection of the hemisphere emission ratio for all-glass vacuum solar collector tubes of 47mm, 58mm and 70mm in outside diameter and 1200mm, 1500mm and 1800mm in length. This detector is composed of a stainless steel cold-wall circulating water jacket, a segmented electric heating rod, a Pt100 platinum resistor and a nichrome alumino-nickel sensor and an automated measuring instrument. With auto heating and auto follow-up temperature control during measurement, the detector provides real-time indication of current and voltage of electric heating and temperature of test piece and ambient temperature, and the computer first gives a time vs. temperature change curve and then the calculation result of hemisphere emission ratio.
