Photovoltaic, also known as photovoltaic, the full name of solar photovoltaic power generation system, refers to a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. Photovoltaics were first used in satellite solar cells in the 1950s. However, with the advancement of technology, photovoltaics have already entered the field of industrial and residential electricity consumption, and are now everywhere. Due to the use of renewable solar energy and no pollution, photovoltaic power generation is considered to be the most promising field of power generation together with wind power.
The downstream demand of the photovoltaic industry can be roughly divided into two categories: one is photovoltaic power generation for industry, commerce and residents, and the other is centralized power generation, photovoltaic power generation for grid-connected operation. Historically, the two types of demand have been one after another, and both have experienced rapid growth. The initial development of photovoltaics first came from the pull of the first type of demand, and then it was relayed by the second type of demand. In recent years, the first type of demand has continued to grow due to technological improvements. Industrial and commercial buildings, outdoor activities and other fields of electricity consumption are in large quantities. Using this solar photovoltaic power generation technology, just like STW portable battery station, STW portable battery station has been doing very well in the aspect of new energy R&D and production.
Take this high-power, large-capacity STW portable battery station as an example, it has a solar MPPT function inside, as long as it is in a sunny place, it can be used with solar photovoltaic panels to charge and use, so that the power generation rate of the solar panels can reach In the best state, and this solar photovoltaic panel also has the advantages of strong waterproof performance, foldable and small size, and easy to carry. It is a truly portable product. Using the method of circulating power supply, we don't have to worry about running out of electricity when we are outdoors. situation.
Speaking of STW portable battery station, the capacity is as high as 417600mAh, which can carry devices up to 1500W. It is equipped with a 220V wall plug interface (AC interface), a 12V DC interface and a 5V USB interface. These three output interfaces, whether it is Indoor or outdoor, no matter what type of electrical equipment, it can be applied to portable battery station, which is an essential equipment for your outdoor travel.
