Solar power plants utilize thermal energy from the sun, which is abundant, available, intermittent, yet cheap. This thermal energy is further transformed into electrical energy using photovoltaic panels. This is one type of solar power plants.
Solar power is the conversion of renewable energy from sunlight into electricity, either directly using photovoltaics, indirectly using concentrated solar power, or a combination. Photovoltaic cells convert light into an electric current using the photovoltaic effect.
Our desire to enter the world of renewable energy is no longer in doubt, we have qualifications from PT. PLN (Persero) for the IPP Solar Power Plant (PLTS) developer service permit. We try to provide our best services on every project we have.
OFF-GRID SYSTEM
With the progress of society and the rapid development of science and technology, people’s demand for energy has gradually increased, especially electric energy. When we talk about electric energy, the most important part is the power generation side and the power transmission side. Although the construction of power transmission and distribution facilities has been accelerating in recent years, there are still some sparsely populated areas or remote areas and special power-using occasions cannot be fully covered due to the high cost of grid deployment. In order to solve the problem of electricity consumption, diesel generators are generally used for power supply. For example, the “communication base station” in remote areas is usually located on the top of an open mountain. In order to solve the power supply of the base station equipment, diesel generators are usually used to generate electricity.
Diesel power generation not only needs to consider the cost of the fuel itself but also the storage, transportation, and noise and safety aspects of the system are unavoidable problems. Then, the application advantages of this kind of solar battery charging system in the above scenarios are very obvious. There are no problems caused by fuel supply and operating noise of the diesel generator, and the cost of the solar energy storage system is also highly competitive.
How Does Off-Grid Solar System Work?
The off-grid solar PV system generally consists of a photovoltaic array composed of solar cell modules, solar charge and discharge controller, battery pack, off-grid inverter, DC load and AC load. The photovoltaic array converts solar energy into electric energy when there is light, and then supplies power to the load through the solar charge and discharge controller while charging the battery pack. When there is no light, the battery pack supplies power to the DC load through the solar charge and discharge controller. Meanwhile, the battery also supplies power directly to the independent inverter, which inverts into AC power and supplies power to the AC load.
ON-GRID SYSTEM
On-grid solar power generation systems include centralized large-scale grid-tied solar systems and distributed small-scale grid-tied solar systems. Centralized large-scale grid-tied solar power stations are generally national-level power stations. The main feature is that the generated energy is directly transmitted to the power grid, and the power grid is deployed to supply power to users. However, this kind of power station has a large investment, a long construction period, and needs a large area. It has not developed much yet. The distributed small-scale grid-tied solar system, especially the photovoltaic building integrated power generation system, is the mainstream of grid-tied solar power generation at present due to the advantages of small investment, fast construction, small footprint, and large policy support.
How Does On-Grid Solar System Work?
The on-grid solar power system is generally composed of photovoltaic array composed of solar cell modules, solar charge and discharge controller, grid-connected inverter, DC load and AC load. The photovoltaic array converts solar energy into electric energy when there is light, and supplies power to the load through the solar charge and discharge controller.
