On-gird solar power system
WHAT IS AN ON-GIRD SOLAR POWER SYSTEM?
It is an electrical system that uses solar PV panels to absorb sunlight, generating DC current, which converts the inverter into AC alternating current and frequency, providing demand for use. Household and company use.
The amount of electricity supplied directly to the indoor electrical system for use; and when it is redundant, it is connected to the national grid.
On the contrary, if the system is not enough, it will be compensated by the grid.
The system will shut down when the power grid is lost. Avoid incidents when solar PV system is transmitted backwards to the grid, causing danger to the maintenance of the grid system.
System connection diagram:
The main equipment of the system
1️⃣ Solar panel
2️⃣ Inverter DC-AC power adapter
3️⃣ AC / DC electrical cabinet
4️⃣ 2-way meter (direction of transmission to the grid and sold to EVN and direction from the grid)
Online monitoring system 24/7 - monitor the amount of electricity generated and sold to the grid
Principle of operation of the system:
> During the day when the sun is shining, the system generates electricity. Priority put into home use.
> If the system generates excess electricity for the usage load, the excess electricity will be pushed to the grid and sold to Electricity (A). If the electricity from the solar system is not enough, the grid will compensate (B).
> 2-way meter with metering function to sell the grid (A) and direction from electricity (B). At the end of the month, Electricity will calculate the amount from (A) and transfer it to the landlord. The landlord pays the electricity bill (B) according to the electricity notice as before.
Thus, the landlord will save electricity money from:
1️⃣ Savings from using solar power to replace grid electricity; especially reducing the amount of electricity from the high price ladder
2️⃣ Proceeds from the sale of electricity to EVN
The system does not use batteries for storage, so it saves huge investment costs and does not pollute the environment (such as Acquy systems containing acids and lead).
Solar energy is clean and endless
Quick installation, fully automatic operation. Low maintenance costs. Easy system upgrade;
You can use the web or phone to monitor the amount of electricity generated by the system;
System life of 25 ~ 30 years;
Reduce electricity costs monthly. Decrease the electric index according to the ladder
Get government permission to EVN to buy back the excess power generated and push it onto the grid
Installation of 2-way electric meters completely free.
With solar power system also works against heat, reducing the roof temperature to 100 ~ 150C to make the house cooler.
