• Karakteristik analiz solè onduleur

    To start developing a solar inverter system, you must first understand the different characteristics of solar cells (PV cells). PV cells are semiconductor devices whose electrical characteristics are similar to diodes. However, PV cells are a source of electricity, and when they are exposed to light (such as sunlight), they become current sources. The most common technologies at present are monocrystalline silicon modules and polycrystalline silicon modules. The model of the PV cell is shown in the figure. Rp and Rs are parasitic resistances, ideally infinity and zero, respectively. The performance of a PV cell will vary depending on its size or the type of load connected to it, and the intensity (illuminance) of sunlight. The characteristics of PV cells…

  • Ki sa ki se yon Battery AGM?

    The AGM battery is a storage battery that was invented earlier and is more widely used. It is a valve-regulated sealed lead-acid battery (also called VRLA battery) using glass fiber separator (AGM), represented by some battery companies in Japan. This battery is a kind of VRLA battery. One type of battery that also belongs to the VRLA battery is the GEL type battery. In the 1990s, the development of communication and electric power made the AGM type battery develop rapidly, with a high market share and the GEL type battery is relatively low. AGM battery uses pure sulfuric acid aqueous solution as an electrolyte, and its density is 1.29-1.3lg / cm3. Most of it exists in the glass fiber membrane,

  • Ki sa ki se sistèm ibrid solè

    A hybrid solar system is a grid-tied solar system that also has a solar battery for energy storage. Sa yo ka bay pi bon nan tou de mond paske ou ka magazen depase enèji nan yon batri pou pouvwa backup pandan yon blakawout, oswa yo itilize pandan aswè chè èdtan prix elektrisite. Avantaj nan toujou gen koneksyon an kadriyaj se ke ou pa bezwen 100% konte sou solè ou ak batri. Sa vle di ou ka gen yon sistèm depo enèji ki pi piti ak pi bon mache konpare ak menm kay la ki konplètman koupe sistèm kadriyaj piblik la. Net metering does economically what a solar battery does physically, ki pèmèt ou magazen valè ekonomik la nan enèji solè depase ou (kWh…

  • Ki jan yo chwazi yon varyateur

    There are many conditions for the selection of transformer capacity of inverter power supply. (1) it can be chosen according to the economic capacity: when the iron loss of the transformer whose load ratio is 0.5-0.6 is equal to the copper loss, the efficiency is the highest, the capacity of the transformer at this time can be called the economic capacity, and the transformer can be selected according to the economic capacity. (2) selection of transformer capacity when the load is motor: if the load is asynchronous motor, the efficiency and power factor of motor should be considered, and the marked power on the nameplate of motor is the active power output of motor. In general, the capacity of the transformer can be selected by double (in high…

  • Ki jan solè travay

    Solar systems are beautifully simple in operation. Solar panels are noiseless with no moving parts and there is minimal long-term maintenance required. As a homeowner, you will enjoy lower utility bills thanks to your solar system. Solar cells convert sunlight into electricity via the “photovoltaic effect.” They are made of semi-conducting materials, the most common being silicon, which is the second most abundant element on the planet. Solar technology has been commercially used since the 1950s in applications ranging from calculators to satellites.   Solar systems function optimally when facing south and in full sun from at least 9:00 AM to 3:00 PM, every day, throughout the year. Oftentimes, it is possible to design around shading caused by chimneys, dormers, or trees.
