The idea of using solar power has appeared a long time ago. But just since 1970�s our technology became capable to realize it. It�s based on simple principle. Sunlight, falling on the collector, concentrates and turns into energy. There are various ways of realizing it, depending on how you will use the energy: to heat the pool water or for energy supply. The main difficulty here � power installation�s cost, because special equipment is much more expensive than traditional energy systems. Besides, investments will pay off only in many years. Despite the cost, solar power is suitable for power supply in urban areas. Investing in development of solar energy is good contribution to the future. At first, profit is insignificant, but it will increase with alternative solar energy�s development.
