WHAT IS SOLAR POWER SYSTEM?
Solar electricity is obtained from the energy of the solar radiation stream (photovoltaic). Photovoltaic energy is absorbed directly through the solar panel and converted into electricity (DC - DC), which is connected to an inverter (Inverter) that converts direct current into alternating current (AC). The converted AC power is directly connected to the existing grid power system, so it is called a grid-tied solar power system.
During the day, priority is given to equipment using solar power (so electricity consumption should be completely reduced during the day).
Excess solar power is generated back to the grid and recorded by a 2-way electricity meter and EVN will return the excess electricity at a unit price of VND 1,943/KWh (in 2020).
There is no solar power at night or when solar power is not enough, use the grid and pay for it EVN at the prescribed price.
HOW DOES THE SOLAR POWER SYSTEM WORK?
Here is a simple diagram showing how to generate clean electricity more affordable from solar power through the system. FOCUS installation for your business.
1 Solar panels (PV module/Solar panel)
Solar panels consist of photovoltaic cells (PV cells) that convert sunlight into direct current (DC).
2 Solar inverter (Ongrid/Offgrid inverter)
This device converts direct current (DC) generated by solar panels into alternating current (AC) connected to the grid and consumed loads.
3 Electrical Cabinet (DC Combiner Box)
AC power from the inverter goes to the electrical cabinet to supply equipment and to the power grid. The switchboard has the function of protecting against AC surge, monitoring and controlling the equipment to switch off the solar power source. .
4 System electricity meter
The meter measures the amount of solar electricity generated.
5 Grid electricity meter
Solar power is connected to the grid and the load. During the day, the load is prioritized to use solar power generated, At night or when solar power is not enough, the load uses grid electricity.
Therefore, the grid meter has a 2-way function, one way records the amount of power consumed by the load at night, and the other way records the value of excess solar power generated back to the grid during the day. Thus, EVN will charge for electricity consumed at night; at the same time pay back for the amount of solar electricity emitted into the grid during the day.
6 24/7 surveillance system
FOCUS SOLAR's monitoring system continuously monitors the system's power production and transmits information over the internet to remotely monitor the system and control the AC switchboard. This ensures that the solar power system operates efficiently and if there is a problem, FOCUS SOLAR will immediately shut down the system; at the same time arrange technicians to handle timely.
The solar power system is always monitored and controlled remotely, ensuring good operation, without affecting the customer's electrical system.
