30KW Off-Grid Solar System In Japan Farm
Japan has regions with varying amounts of sunlight throughout the year. Generally, southern regions of Japan receive more sunlight than northern regions. It's important to assess the average solar irradiation in your specific location to determine the system's potential output.
We are going to introduce how the off-grid solar system work in Japan.
Photovoltaic Geographical Information System In Japan
The Photovoltaic Geographical Information System (PV-GIS) is an online tool developed by the European Commission's Joint Research Centre (JRC) that provides geographical information related to solar energy. It offers data and maps to estimate the potential solar energy production in different regions around the world, including Japan
By using PV-GIS, individuals, businesses, and policymakers in Japan can make informed decisions about solar energy investments, system sizing, and project planning. The tool helps to identify areas with high solar potential, optimize the placement of solar panels, and estimate the expected energy output of a PV system in a specific location.
How does the 30kw Off-Grid Solar System Work in Japan?
An off-grid solar system works independently of the traditional electrical grid. It generates electricity from solar panels and stores it in batteries for later use. Here's a general overview of how an off-grid solar system works:
Solar Panels
The system consists of solar panels, also known as photovoltaic (PV) panels, which are installed on rooftops or ground-mounted structures. These panels convert sunlight into electricity through the photovoltaic effect.
Power Inverter
When electricity is needed, the DC power from the battery bank is converted into alternating current (AC) electricity using a power inverter. AC electricity is the standard form of electricity used in most household appliances and electrical devices.
Charge Controller
The solar panels generate direct current (DC) electricity, which is then fed into a charge controller. The charge controller regulates the charging process, preventing overcharging or damage to the batteries.
Battery Bank
The DC electricity from the charge controller is stored in a battery bank. The battery bank stores excess energy generated during sunny periods for use when sunlight is limited, such as during the night or on cloudy days. The batteries are typically deep-cycle batteries designed for repeated charging and discharging.
In an off-grid solar system, the battery bank serves as an energy storage solution, allowing you to have electricity even when there is no sunlight or during times of increased demand. It provides energy independence and can be a reliable power source for remote locations or areas without access to the traditional electrical grid.
