main advantages of solar systems:
• high efficiency;
• efficient operation at sub-zero temperatures;
• significantly better insulation from the environment (vacuum is the best insulator);
• vacuum tubes withstand extremely low temperatures without damage;
• termotrubok heat transfer efficiency leads to excellent thermal solar power;
• form vacuum tubes increases the total the amount of absorbed solar energy;
• by deformation of one pipe does not need to change the entire solar installation;
• very low operating costs;
• easy installation;
• high service life
