Sustainable savings with grid-connected solar power systems

Faced with the reality of constantly increasing electricity prices and increasing energy demand, grid-connected solar power systems have emerged as an optimal solution for the problem of saving and efficiency. This technology allows taking advantage of natural light sources to create stable electricity, while reducing dependence on the national grid. With the ability to save long-term costs and reduce emissions, grid-connected solar power is affirming its important role in the trend of clean energy development in Vietnam.Hệ thống điện mặt trời hoà lưới tại mái nhà dân

What is grid-connected solar power? Basic operating principle

Concept of grid-connected solar power

Grid-tie Solar System is a system that converts sunlight into electricity for use in parallel with the national grid. Solar power is prioritized for use in household appliances, the excess electricity will automatically be fed into the EVN grid, helping users save costs and reduce the load on the national power system.
Unlike standalone solar power systems that require battery storage, grid-connected solar power operates without batteries, helping to optimize initial investment costs, reduce maintenance costs, and maintain high performance for many years.

Working principle

The principle of grid-connected solar power system is designed to be smart, automatic and safe.
The operating process consists of three main steps:

Step 1: Solar panels absorb sunlight and generate direct current (DC).

Step 2: Grid-tie inverter converts DC to alternating current (AC) with the same frequency and voltage as the national grid.

Step 3: AC power is given priority to the operating device. If there is excess solar power, the system will push it back to the grid, and when it is dark, the grid will automatically supply the missing power.

? All processes are completely automatic, helping users always have a stable power source without manual operation.

Structure of grid-connected solar power system

A basic grid-connected solar power system consists of 5 main parts:

Investment costs and economic efficiency when installing grid-connected solar power systems

When considering investing in a grid-connected solar power system, the initial cost is usually a relatively small amount compared to the total value of use over the life of the system. On average, the initial investment is only 2-3 years of electricity consumption, but the system can operate efficiently for 25 years or more — meaning you get “free” electricity for more than 20 years after the investment is paid back.

Compared with other forms of investment, grid-connected solar power brings very clear economic efficiency:

• Save 80 - 90% on monthly electricity bills depending on consumption and installed capacity.

• Fast payback period, usually only about 2 - 3 years under normal usage conditions.

• No need for battery storage, which significantly reduces maintenance costs and increases power efficiency.

• Sustainable efficiency, as solar panels have an average lifespan of 25–30 years and still maintain their efficiency after 20 years of use.

In addition to economic efficiency, grid-connected solar power systems also bring indirect benefits to businesses and households:

• Helps stabilize energy sources, reducing dependence on the national grid.

• Show the image of a "green consumer", environmentally friendly.

• Increase the aesthetic value and real estate value of the project.

Investing in grid-connected solar power is a way to “spend once – save many times”, bringing long-term and sustainable financial benefits.

Sustainable savings – long-term investment with grid-connected solar energy

Long-term energy cost savings
Installing a grid-connected solar power system helps users reduce their monthly electricity bill by an average of 40–60%. After the payback period, the entire electricity generated is almost free, providing stable and sustainable savings over more than 20 years of operation.

Stable and proactive energy source
Grid-connected solar power operates in parallel with the grid, helping users have a stable power source even when demand increases. The system automatically coordinates between solar power and grid power, ensuring that all devices always operate smoothly without interruption.

Environmentally and socially friendly
Each solar power system installed significantly reduces CO₂ emissions, helping to slow down climate change. Using clean energy also demonstrates the responsibility of individuals and businesses in protecting the environment and moving towards sustainable development.

Increase asset value and brand image
A home or business with a solar power system is often more valuable due to its energy savings and modern, environmentally friendly image. For businesses, this is also proof of their commitment to green development, enhancing their reputation with partners and customers.

One-time investment – ​​long-term benefits
The average lifespan of a grid-connected solar power system can be up to 25–30 years, while maintenance costs are very low. That means with just one investment, users can rest assured to use clean energy, save costs and bring sustainable benefits for decades.
