  • How to calculate the module power of PV off-grid system?
    • March 03. 2022

    The module power is confirmed according to the daily power consumption of the customer. The design principle of the module is to meet the daily power demand of the load under average weather conditions, which means that the annual power generation of the solar module should be equal to the annual power consumption of the load. Because weather conditions are below and above average, solar modules a...

  • PV energy storage system -- PV off-grid system configuration points explained
    • February 25. 2022

    PV energy storage system, generally refers to applications with PV modules, including energy storage batteries and other related equipment in the system. According to whether the stored energy needs to be sold on the grid, PV energy storage system can be divided into PV off-grid system and PV on/off-grid hybrid system. Here, we mainly focus on the PV off-grid system to make a brief introduction. P...

  • The differences between mono-crystalline and poly-crystalline
    • February 18. 2022

    At present, PV modules are mainly made of mono-crystalline silicon wafers and poly-crystalline silicon wafers, so should I choose mono-crystalline or poly-crystalline silicon? What is the difference between them? 1.Appearance From the appearance of the above, the four corners of the mono-crystalline silicon cells show a rounded shape, no pattern on the surface. While the four corners of poly-cryst...

  • PV Off-grid System Configuration Points Introduction
    • February 11. 2022

    PV modules, off-grid inverters (including PV chargers/inverters), energy storage batteries (lead-acid/GEL/lead-carbon/tertiary lithium/LiFePo4, etc.), PV mounts, cables, and distribution boxes are all important components of off-grid PV systems. The biggest difference between off-grid systems and on-grid systems is that on-grid systems take investment income as the premise of calculation, while of...

  • Solar PV Water Pumping System
    • January 26. 2022

    The basic principle of "PV Water Pumping System", also called "Solar PV Water Pumping System", is to use solar cells to directly convert solar energy into electrical energy, and then drive all kinds of motors to drive the water pump to carry water from deep wells, rivers, lakes, ponds and other water sources. It has many advantages such as no noise, fully automatic and high reliability, and good a...

  • Classification of Photovoltaic Inverters
    • January 21. 2022

    Energy storage system integrate the functions of grid-connected photovoltaic power generation + energy storage power stations, storing electricity when it is in surplus and inverting the stored electricity to output to the grid when it is in shortage, playing the role of peak shaving and valley filling, which is one of the main development directions in the future. The PV inverter is the control c...

  • What is an MPPT solar controller?
    • January 14. 2022

    The MPPT solar controller system is an electrical system that enables the photovoltaic panels to output more electricity by adjusting the working state of the electrical modules. It can effectively store the DC electricity emitted by the solar panels in the solar panel battery system and can effectively solve the problem of domestic and industrial electricity consumption in remote areas and touris...

  • Shingled Solar Technology is Beginning to Show its Edge
    • January 11. 2022

    Shingled solar technology interconnects cell slices with conductive adhesive, eliminating solder tape welding, reducing shading area and line loss, saving space, encapsulating 13% more cells than conventional 60-type modules, and increasing power by more than 20W, significantly higher than other technologies such as half-sheet and MBB. However, the cost has to be further reduced compared with conv...

  • The Coming Of Age Of High-Efficiency Micro Inverters
    • January 06. 2022

    With the gradual development and improvement of the household market, the advantages of micro inverters in terms of safety have received more and more attention. Micro inverter system adopts full parallel circuit design, which can give priority to inverting the DC power of each module into AC power and then connect to the grid, only about 60V DC voltage exists, which has the advantage of natural n...
