On a rainy day, how much can photovoltaic power generation?

Generally speaking, the solar panel is only suitable for use in sunny natural environment, meet cloudy or rainy weather is bad to use; Some cells ( Such as the tesla's; Firewall; The battery) Although power can be stored for the rainy day or night use, but for some

in general, solar panels are only suitable for use in sunny natural environment, is not suitable for use in cloudy or rainy day. Some cells ( For example, tesla; The firewall. The battery) Although the use of electric energy can be stored for a rainy day or night, but the technology for some insufficient light region, there is no value in terms of efficiency and cost. Suzhou university developed a new type of solar panels can solve this problem. It is reported that they used a solar panels. The friction generator ( TENG) ； Catching raindrops falling to produce energy. Nano generator is a device can convert mechanical energy into usable electrical energy. It can rain on a small scale to achieve this goal. Solar panels that use such TENG technology is still very light, can be installed on the roof. Researchers in TENG was embedded between solar cells and a barrier made by different transparent plastic or polymer materials. Because of several layers of structure are connected, but they can run independently, so the solar panel can be in different weather conditions to produce electricity. At present, the bottleneck affecting the popularization and application of this new technology is the product of the production cost is high. If we can solve this problem, solar energy will become a kind of high efficient, clean new energy, even in those due to insufficient light is considered not suitable for solar energy collection area. According to expert analysis, in spite of the limitation of weather conditions, the solar energy is still one of the world's fastest growing energy. At present, the cost of installing commercial solar panels has fallen by 58%, to 2040, renewable energy is expected to account for 40% of global output. Therefore, the development prospect of this new technology is very promising.
