Problems solved by technology

[0003] Solar energy is a necessary energy source for human beings to survive, and strong solar heat radiation will also bring a lot of inconvenience to people's production and life
In hot summer, the surface temperature of building roofs, offshore drilling platforms, oil tanks, automobiles, etc. directly exposed to sunlight continues to rise, which not only increases energy consumption, but also brings major safety hazards to normal production operations
