Solar Collectors
Unitech Solar thermal collectors work in all weather. They do not need direct sunlight to operate. That's because our solar collectors takes advantage of diffuse radiation, as well as direct radiation, delivering the sun's energy even on cold, cloudy or foggy days.
How is this possible?
Collector Overview
The key is a vacuum tube the outside air temperature has little influence. This means you can get hot water even in bad weather and add heat to a tank that is already hot. The Unitech Solar Energy System integrates easily with your existing hot water system. Major alterations are not required. Position is not critical and it can be mounted to suit your situation. It does not need to point straight south. Because of it’s high efficiency, Unitech Solar is the most practical solar system available

These rays of sun unseen by the human eye penetrate the atmosphere even when the sky is not totally clear or on a day with little sunshine.
The collector is a supplement for hot water heating & space heating for COMMERCIAL, RESIDENTIAL, and and other FACILITIES that use hot water or space heating.
Solar thermal systems are generally composed of panels that convert sunlight to heat. The systems may be used to heat domestic hot water or a swimming pool, or to even make a contribution towards under floor heating. Solar heating panels are one of the most cost effective ways to reduce your utility bills and make a positive contribution towards the environment. In fact the amount of pollution reduced by installing a domestic solar heating system is equivalent to taking one car off the road (i.e. about 1500m3 CO2 per annum).
There are two types of solar heating collectors; the conventional flat plate collector and the more efficient vacuum tube collectors.
Flat plate solar heating panels vs. Evacuated tube solar heating panels
Evacuated solar heating panels are more efficient than conventional flat plate type collectors and will perform considerably better in cold, cloudy and windy conditions. The higher efficiency of evacuated solar heating tubes mean less area is covered on the roof by the solar heating panels - a desirable feature appreciated by most customers.
Having less solar heating panel area on the roof reduces the fluid content of the solar heating system enabling quicker response to solar radiation.
Vacuum is the best possible insulation for a solar heating panel. It safeguards the collector from moisture, condensation and pollutants - resulting in improved durability and all-year-round performance.
Summary of advantages of evacuated tube over flat plate solar heating panels
1. High efficiency even at low light intensities (e.g. cloudy days)
2. Ability to achieve high temperatures
3. The solar heating panels are easy to install due to its lightweight design
4. Improved aesthetics - Modern and elegant design
5. Covers less roof area - Less visually intrusive
6. Each tube on the solar heating panel is individually replaceable allowing for easy repair in case of damage.
7. Longer life span providing an improved return on investment
