Solar power is an inexhaustible source of renewable energy that nature offers us human beings. It is gradually becoming familiar with people around the world.
In Vietnam, solar power installation services have flourished in recent years. Many incentives from construction contractors as well as preferential policies of the government and EVN have contributed to promoting the movement of installing solar power up high.
Surely of us – who are intending to learn about rooftop solar PV – are wondering about the structure of the system? How the solar power system works? … Please join Tri Viet to answer your questions.
What is solar power?
Solar power is an electrical energy source generated from the conversion of sunlight (photovoltaic) into electricity by using solar panels (Often called photovoltaic cells, Solar Panel, Solar cell modules or photovoltaic modules). The mechanism of action of the solar cell is based on the photoelectric effect in physics.
Solar power grid (Grid connected) is what? Structure diagram of solar power grid like?
The structure of the grid-connected solar power system in general will include the following parts:
1. Solar Panel Solar Panel
2. Inverter grid
3. Remote monitoring system via internet, smart phone
4. Support frame system, Surge and grounding lightning cutting system, Electrical cable and material systems, accessories in the system
5. 2-way electricity meter
Working principle of solar power system
Solar panels convert solar radiation into direct current (DC). That DC current will be converted into alternating current (AC) by the inverter equipped with MPPT (Maximum Power Point Tracking) algorithm to optimize the energy generated from the solar cell system.
The AC power source from the solar battery system will be connected to the main electrical cabinet of the area, synchronize with the existing grid, provide power in parallel with the mains, help reduce power consumption from grid of the area of use.
When the utility power is lost, the inverter will quickly disconnect from the grid. This ensures that in the event of a power outage, the solar battery system does not emit into the grid, causing danger to the repair staff.
Remote monitoring of the solar power system via computer or smartphone
The system allows to monitor the operation of the entire system locally or remotely via smartphones, computers … connected to the internet to help the operator easily monitor the operation of the entire solar power system.
All operating parameters of the system such as capacity, power generated, operation status … will continuously update to analyze the operation and give necessary recommendations for the system to work best. The operator can monitor the operation of the system anytime, anywhere.
Depending on each type of Inverter, the company will have its own App for Android, IOS, but basically it gives specific parameters.
The main functions of monitoring system:
- Generated energy of grid-connected solar cell system (kW);
- Energy parameters are represented by graphs.
- CO2 emission reduction (kg);
- Required load capacity (kWh);
- Solar panel voltage (V).
- Solar panel current (A).
- Status of the inverter.
- The state of the panels.
- AC voltage.
- AC current.
- AC Power Factor (AC Power Factor)
- The total amount of electricity accumulated during the day, month, or year.
- Chart of generating capacity per day.
- Install the solar energy monitoring screen in the reception area for the purpose of propagating and promoting the use of clean electricity generation technology from renewable energy sources and friendly with the environment.
Solution 2-way meter to measure power in selling excess electricity to EVN
Similar to the principle of operation of current meters, however, for the method of measuring electricity sources from the grid, solar energy and load will be done on a smart electricity meter. (Smart meter), thereby, makes it easy to manage and analyze the system simply.
This smart electric meter includes smart features such as:
– Measure the index of electricity from the grid, electricity from the solar cell system.
– Total power consumption
Ability to remotely monitor electrical parameters via 3G / GPRS / GSM
– Many modes to store electricity usage times, electricity tariffs from time to time.
* Advantages:
– Simple, compact system
– Ability to store information well.
– The ability to remotely monitor and collect information.
What is independent solar power? Structure diagram and operating principle?
The structure of the independent solar power system is as above but without the grid connection and the meter.
Also add a battery for storage and a charge controller.
