1. What is on grid system? (Also called Grid Tie System) 并网系统介绍

The on-grid solar power system is an electricity-generating solar power system that is connected to the utility grid. Electricity generated by solar panels is routed to the grid from where it is supplied to various appliances.

An on-grid solar system consists of solar panels, inverters, a power conditioning unit, and grid connection equipment. They range from small residential and commercial rooftop systems to large utility-scale solar power stations. When conditions are right, the grid-connected PV system supplies the excess power, beyond consumption by the connected load, to the utility grid.

On-grid solar systems are ideal for places with less than 2 hours or no power outages during the day. Since no batteries are connected, this system is economical without no recurring costs for replacing the components.

2. Advantages of an on-grid solar system 并网系统优势

(1) Better Return on Investment (ROI)

With the cost of batteries being eliminated the overall cost of an on-grid solar system reduces considerably. Also, this solar system generates the highest amount of power in comparison to other solar system types. Again, with a reduced monthly bill and minimal maintenance charges, you get around 25%-35% Return on Investment (ROI). As per this, the customer earns a good sum of money on the amount they invested in installing solar panel system

(2) Easy Maintenance

With no batteries involved maintenance of an on-grid solar system becomes easier. Also, the cost of replacing and repairing batteries is also eliminated. Plus, there is hardly any maintenance cost or special effort required to maintain. Get to know about what is on grid solar system advantages for better understanding before deciding.

(3) High Reduction in Electricity Bills

With a bidirectional meter and a net meter, you need to pay only for the units consumed after stored solar energy is exhausted. With very little consumption of electricity from utility providers, your electricity bill will be gradually lesser than usual. Several consumers mentioned having reduced about 90% of their bills.

(1) Synchronize With Other Power Sources

In case of grid power is unavailable, you can connect a diesel generator to serve the purpose. This on-grid solar system can be synchronized with various power sources.

(5) Increased House Value

An on-grid solar system increases the resale value of your house or business. With more and more people shifting to solar panels for electricity generation, look out for houses with pre-installed solar systems. It saves up their time and effort which you get to benefit from it.
