What are the advantages of bifacial solar panels? The core competitiveness of the photovoltaic industry is that the cost of electricity per kilowatt hour is low enough. The key factor affecting the cost of electricity per kilowatt hour is the technical level of photovoltaic modules, because the initial investment of solar panels in the system accounts for a large proportion, which dire...
What are the important accessories for solar photovoltaic modules? EVA is one of the most critical packaging materials in the production process of solar modules. It covers the top of the cell and seals it in the middle to protect the cell; EVA has a high light transmittance after melting, which can improve the light transmittance. The incidence rate increases the output power of the module; in ad...
Solar energy is an inexhaustible and inexhaustible renewable energy source for mankind, and plays an important role in the long-term energy strategies of countries around the world. Thin-film power generation relies on thin-film solar cell chips that are light, thin and flexible. Crystalline silicon power generation has high energy conversion efficiency, but the solar panel must be thick enough. S...
With the rapid development of society and economy, the demand for energy is increasing day by day. As an inexhaustible and inexhaustible green renewable energy, solar energy has received extensive attention worldwide. Solar cells are one of the important components of photovoltaic systems. Today, let's talk about how to deal with solar cells after recycling? A brief introduction to solar cells A s...
Electrochemical energy storage battery is an extremely important electrical energy storage method. Energy storage battery is a device that stores electrical energy through the mutual conversion of chemical energy and electrical energy. Up to now, the commonly used battery systems have certain problems. For example, traditional lead-acid batteries contain strong pollutants such as heavy metals; the...
What is the new direction of energy storage? Iron-chromium flow batteries: a new direction for energy storage As we all know, the main power of the new energy vehicles currently on the market is provided by the battery, and the service life has a certain number of years. According to statistics, as of the end of June 2022, my country's new energy vehicles reached 10.01 million. With the increase i...
According to incomplete statistics from relevant institutions, as of September this year, more than 26 expansion projects related to the production of energy storage batteries and power batteries have been announced, with a total investment of over 290 billion yuan and a total production capacity of 820GWh. The process and product goals pursued by energy storage cells and power cells are different...
When the utility grid is powered off, the grid side is equivalent to a short-circuit state, and the grid-connected inverter will be automatically protected due to overload. When the microprocessor detects an overload, in addition to blocking the SPWM signal, it will also disconnect the circuit breaker connected to the grid. At this time, if the solar cell array has energy output, the inverter will...
