With more than 20 years experience in solar energy, Sun Power Technology once again leaps into the forefront with the introduction of their new ISOLL range of solar energy products. This remarkable 5th generation solar technology is the fruition of a joint venture between Germany and China. It came up trumps after stringent testing over the past couple of years under the severe climatic conditions in Northern China, Russia as well as in Europe. The highly efficient boro-silicone glass vacuum collector tubes were tested to withstand hail stones in excess of 35mm diameter, and boast an incredible 93% efficiency rating! Combined with the unsurpassed thermal properties of the SolarTherm geyser, we are therefore justifiably proud to announce the availability of these top level international standard products for both domestic as well as industrial applications to the South African energy consumer.

These 'next generation' solar heating units make use of boro-silicone glass vacuumed collector tubes. Inside the vacuum tube there is a copper absorber plate coated with specially formulated blue high absorption / low emission pigment that will absorb the light energy from the sun. This energy is converted into heat and conducted to the central copper pipe with very special thermal properties. Hot vapour from this gas will transfer the heat upwards towards the external heating element where it will then be available for heating purposes.

Well.. gone are the days of inefficient, leaking solar panels and those unsightly flat plates that freeze up in winter. Goodbye also to "if one part fails, the rest fail too". These interchangeable glass vacuum tubes never come into contact with the water, making it both safe and simple to maintain without interrupting the normal operation of the system. Should a vacuum tube accidentally be damaged, it can be replaced without affecting normal operation of the geyser. In fact, the unit can safely continue to function minus a tube or two until a replacement tube can be fitted. Impressed? So are we.. that's why we at ISOLL decided to take up the challenge to adapt this system specifically for the potentially much more favourable, yet very challenging African extremes. Our particular conditions also required the introduction of a 12 Volt dc pump when thermo-syphoning is not possible. This has a dedicated photovoltaic panel to ensure an independent backup system during possible power failures. All our research and development facilities are located on our premises.. which means; we lead, others follow. Installations are done in one day to ensure minimal discomfort to the household. The ISOLL range is fully SABS compliant.

Covered in icy sleet, this ISOLL Aquarius will quite simply go into hibernation until the sun returns. Totally unaffected by the sub-zero temperatures, it will simply shrug off it's chilly coat and continue to function as if it never happened..

Superior quality components and workmanship plus the functional simplicity of our systems means an estimated life expectancy of about 25 years. All ISOLL products carry a Ten Year Warranty.
