Solar Energy for Home systems are becoming increasingly popular among users for their clean and efficient characteristics. This seemingly magical technology is in fact quite simple, yet it can provide your household with reliable electricity. This article will delve into how Solar Energy for Home works and how it transforms ordinary sunlight into electricity usable by your home appliances.
1.Solar power panels generate direct current
Home solar power systems typically install multiple solar power panels on the roof, each panel consisting of dozens of photovoltaic cells made of monocrystalline silicon or polycrystalline silicon. These solar power panels capture sunlight through the photovoltaic effect and convert it into direct current. The number and design of panels determine the power generation capacity of the system.
2. Solar Inverter converts electricity into usable alternating current
Since home appliances use alternating current, the direct current produced by solar power panels needs to be converted by a Solar Inverter. In most home systems, a string inverter, also known as a central inverter, is used to receive power from all solar power panels. Additionally, module-level inverters can be used, connecting each solar power panel with a small inverter to achieve the conversion from direct current to alternating current.
3. Solar Inverter supplies power to the household
Solar Inverter, after completing the current type conversion, transmits the outputted alternating current to the household circuit board, supplying power to the home's electrical loads. For grid-tied solar systems, you can use solar power, grid power, or a combination of both at any time to meet home electricity demands. If the load exceeds the power supplied by the inverter, it can be met through multiple sources, partly from solar power and partly from the grid.
4. Excess solar energy output to the grid
In cases where electricity generation exceeds household demand, the surplus solar power will be sent to the grid. At this point, a net metering meter needs to be installed to separately record the electricity output to the grid and the consumption from the grid. This allows users to enjoy the surplus of electricity generated beyond their needs, injecting it into the grid and earning corresponding benefits.
Solar power panels require sunlight to generate power, and during the night sunlight is not available. Therefore, to supply power to the household at night, the solar system is equipped with battery packs for backup and storage. During the day, the batteries charge through photovoltaic input or grid power, storing excess solar energy. At night, the batteries supply power to the loads through the inverter, ensuring the continuity of household electricity supply.
Solar Energy for Home systems may seem mysterious, but they are simple and efficient in principle. By capturing solar energy and converting it into usable electricity, Solar Energy for Home injects clean, sustainable energy into our lives.
