Solar Heat
Often mistaken for solar electric or photovoltaic power solar heat is the latest in solar power technology. Solar heat can be utilized to generate electricity with the right components. However, solar heat is an abundant source of free solar energy. If absorbed by efficient solar panels, solar heat can provide up to 90% of the heat required for any process.
Solar heat is not the same as the heat/warmth we feel from the sun. In fact, solar heat cannot be felt or seen because it is converted from the sun's ultraviolet rays into heat. Using a special UV absorbing coating the sun’s rays can be converted into heat. Once this heat is gathered it can be used for to heat any process. From domestic hot water to pool heating, the ability to covert the sun's rays into heat is very affective and useful. Solar heat is renewable and thus is a significant cost savings alternative to non-renewable energy sources.
In the winter time, when a renewable source of heat is desired, the best source of renewable heat is solar heat. Despite the freezing ambient temperatures, which normally create significant heat loss from a heat source, Solar Heating Canada's high efficiency solar heating panels generate a substantial amount of heat. Normally, the vast temperature difference between the ambient and most solar panels hinders the solar panels' ability to generate solar heat though the absorption of the sun's rays. However, the high efficiency double wall evacuated tube panels can absorb a large amount of the sun's rays and convert them into solar heat even in -30C temperatures.
The efficiency of these panels makes solar heat a more desirable and useful renewable source of energy than solar electricity which, as mentioned before, is harnessed by photovoltaic (PV) panels. Currently, the cost of PV panels is too high to allow for a fast payback period and the principle amount is quite substantial. Meanwhile, with solar heating panels the payback period is much shorter and the principle amount is much lower.
Solar heat has many uses and is a great method to save energy, reduce heating costs and reduce green house gas emissions.
