Module

The building blocks of photovoltaic systems are solar photovoltaic modules. Solar photovoltaic modules are electrical devices that can directly convert photon energy into electrical energy. There are three generations of solar photovoltaic modules: the first generation (1G) crystalline silicon cell (c-Si), the second generation (2G) thin-film cell (such as CdTe, CIGS, amorphous silicon, and GaAs), and the third-generation (3G) Organic, dye-sensitized, perovskite, and multi-junction batteries.

Traditional c-Si solar photovoltaic modules are usually connected in series and encapsulated in solar modules to protect the solar photovoltaic modules from the weather. The solar photovoltaic module is covered by a toughened glass, a soft and elastic sealant, a weather-resistant and fire-resistant back film material, and an aluminum frame around the outer edge. Solar photovoltaic module modules are electrically connected and installed on a supporting structure to construct a string of modules, usually called solar photovoltaic modules. The solar photovoltaic module array is composed of one or more such panels. A solar photovoltaic module array or a solar array is a linked collection of solar modules. The power that a module can generate rarely meets the needs of families or businesses, so solar photovoltaic module modules are connected together to form an array. Most solar photovoltaic module arrays use inverters to convert the direct current generated by the modules into alternating current, which can power lights, motors, and other loads. Solar photovoltaic modules in a photovoltaic array are usually connected in series to obtain the required voltage; then separate series and parallel connections are used to allow the system to generate more current. Solar photovoltaic modules are usually under STC or PTC It is measured in watts. Typical panel ratings range from less than 100 watts to more than 400 watts. The array rating is composed of the sum of the panel ratings, in units of watts, kilowatts, or megawatts.

The efficiency of solar photovoltaic modules

The size of a typical 150-watt photovoltaic solar photovoltaic module is about one square meter. Taking into account the weather and latitude, for 5 hours/day of sunshine, this solar photovoltaic module is expected to generate an average of 0.75 kilowatt-hours per day. The increase in temperature will reduce the output and life of the solar photovoltaic module. Allowing ambient air to flow through the solar photovoltaic module, if possible, can reduce this problem. The effective module life is usually 25 years or longer. The payback period of the investment in photovoltaic solar energy installations varies greatly and is usually not as useful as calculating the return on investment. Although it is usually calculated as between 10 and 20 years, the financial payback period can be much shorter if there are incentives.

The influence of temperature on solar photovoltaic modules is usually quantified by some coefficients related to the change of open-circuit voltage, short circuit current, and maximum power with temperature.

Since the voltage of a single solar cell is low, multiple cells are connected in series when manufacturing the "laminate" of solar photovoltaic modules. The solar photovoltaic module laminate is assembled into a protective weatherproof enclosure to make a photovoltaic module or solar photovoltaic module. The solar photovoltaic modules can then be stringed together to form a photovoltaic array. In 2012, the efficiency of solar photovoltaic modules available to consumers was as high as about 17%, while the efficiency of commercial solar photovoltaic modules was as high as 27%.

The manufacturer of Anhui JF Solar Technology Co., Ltd. (JF Solar) is a high-end solar photovoltaic module manufacturer with the most advanced equipment, technology, and quality in the world.
