The aging behaviour of most of these plastics has been widely studied for normal outdoor exposure and in artificial weathering devices, and are thus briefly described here. Very Little information is available, however, regarding their short-term performance under actual service conditions in solar energy installations; none has been reported on their long-term durability.Plastics have various degrees of flammability and therefore special care should be taken by using materials with adequate tire resistance andlor appropriate design in applications where a fire hazard may exist.
IhmowmONSolar energy is the ideal source of energy for space heating and power generation: it is practically inexhaustible, is easily converted and its use does not result in pollution. Efforts to harness solar energy have been accelerated during the last decade as world demand for energy grows.Although solar energy is "free", the cost of making
