Increase profits from installing solar power in factories

In the context of increasing electricity prices and increasing demand for electricity in industrial production, optimizing energy costs has become a matter of survival for businesses. One of the outstanding solutions today is factory solar power - a system that helps businesses generate their own clean electricity, reduce dependence on the national grid, and at the same time enhance the image of a "green business". Not only bringing environmental benefits, solar power systems for businesses also help increase profits significantly through saving operating costs and quick capital recovery.

1. What is factory solar power and why is it suitable for manufacturing businesses?

1.1 Concept of factory rooftop solar power system

Factory solar power is a system of installing solar panels on the factory roof (also known as factory rooftop voltage) to collect sunlight energy and convert it into electricity.

The generated electricity can:

• Used directly for equipment and machinery in the factory, helping to significantly reduce the amount of electricity consumed from the national grid.
• Connect to the EVN grid to offset electricity, reduce monthly electricity bills.
• Integrate storage batteries (hybrid system) to store electricity, helping the factory to operate stably even during power outages or peak hours.

This system operates fully automatically, durably and safely, providing a clean, stable and long-term energy source for businesses. With the characteristics of large roof area, high electricity demand and continuous operation, solar power models for factories are especially suitable for businesses in the fields of garment, mechanics, plastics, food, electronics, wood and logistics.

1.2 Structure of factory roof voltage system

Cấu tạo hệ thống điện năng lượng cho nhà xưởng

A standard business solar power system includes the following main components:

• Solar Panel

As the "heart" of the system, it is responsible for collecting sunlight and converting it into direct current (DC).
Current solar panels have high efficiency (18–23%) and a lifespan of more than 25 years.
Depending on the size of the factory, the number of panels can range from several hundred to thousands.

• _{^{Grid-tie inverter}}

This is a device that converts DC electricity into alternating current (AC) electricity compatible with the industrial electrical system of the enterprise.
The inverter also helps to coordinate power output, monitor and protect the system, ensuring stable voltage for the entire factory.

• Truss frame

Made from aluminum alloy or galvanized steel, designed to suit the roof type (corrugated iron, concrete, steel frame) of each factory.
The support frame not only holds the solar panel firmly but also withstands storms and heavy rain, while creating an optimal tilt to collect solar energy most effectively.

• Electrical cabinets, wiring and protection systems

Including distribution cabinets, circuit breakers, lightning protection switches, dedicated wires and 2-way meters.
All are installed according to industrial electrical safety standards, helping to protect the system and operators.

• Power output monitoring software

Through online platforms (Ego Solar Monitoring, Growatt, SMA,...), businesses can track power output, performance and savings in real time on their phones or computers.

Note: When designing a factory rooftop solar power system, it is necessary to carefully calculate the roof structure, tilt angle and sunlight direction to achieve maximum efficiency. In addition, you should choose a reputable construction unit to ensure electrical safety, frame durability and connection quality.

1.3 Why suitable for business workshop?

There are many reasons why commercial solar power is becoming a preferred choice in today's industry — not only economically, but also as a sustainability strategy.

• Large roof area – maximum potential

Factories often have roof areas ranging from several thousand to tens of thousands of square meters, making them ideal for installing large-capacity solar power systems for factories (50 kWp – 1MWp or more).
The larger the roof → the larger the electricity output → the higher the investment efficiency.
This is an advantage that few other energy models can offer.

• Daytime production activities – coincide with electricity generation hours

Manufacturing enterprises operate mainly from 8am to 5pm – exactly when the solar power system reaches its peak efficiency.
This helps enterprises take advantage of almost 100% of the electricity generated, reducing grid electricity costs and avoiding overload during peak hours.

• Significantly reduce operating costs by optimizing solar power sources.

On average, a factory rooftop solar power system can reduce the total monthly electricity bill by 30–60%.
For businesses that consume a lot of electricity (such as mechanical, garment, plastic, and refrigeration industries), this savings is equivalent to tens to hundreds of millions of VND per month.
In addition, businesses can also offset electricity with EVN through a 2-way meter, helping to optimize self-generated electricity sources.

• Increase image and brand value of "green business"

Installing solar power for businesses is not only an economic problem, but also a long-term strategy to help improve the business image.

Businesses with clean energy systems:

• Easily achieve ESG, ISO 50001, ISO 14001 certification.
• Highly appreciated by FDI partners and global supply chains.
• Affirming the image of a responsible enterprise - towards a sustainable future.

Therefore, factory solar power is not only a profitable investment, but also a lever to help businesses enhance their brand in the green economic era.

2. Financial efficiency analysis when investing in solar power for factories

Investing in a factory rooftop solar power system is not only a solution to save electricity, but also a sustainable profitable investment channel for businesses. By taking advantage of free solar energy, businesses can significantly reduce operating costs, shorten payback time and create long-term profits.

2.1 Example model

Let's look at a real example of the effectiveness of solar power investment for manufacturing enterprises in the South:

• Factory size: 5.000 m²

• Average electricity bill: 60.000.000 VND/month

• Recommended system capacity: 200 kWp

• Investment costs: 1.600.000.000 VND

• Average savings: 60.000.000 VND/tháng

• Total savings per year: 720.000.000 VND/tháng

• Payback period: chỉ 2,2 năm

• Profit after 25 years:14.400.000.000 VND

With an investment of 1.6 billion VND, the business recovered its capital after just over 2 years and for the next 20 years, it used electricity almost for free, generating profits more than 9 times the initial investment cost.

This is an extremely impressive figure, especially when compared to other investment channels such as real estate or stocks — low risk, high profit and long-term stability.

2.2 ROI Performance Illustration Graph

For easy visualization, we can see the average ROI (Return On Investment) efficiency of a factory solar power system:

A business investing in rooftop solar power can recover its capital after only 2-3 years, while the system continues to generate stable profits for the next 20-25 years. This is an outstanding financial efficiency that the business achieves with almost zero risk.

3. Solar power system installation process for businesses

To ensure high efficiency and operational safety, the installation of solar power systems for businesses needs to be carried out according to standard procedures, from survey to acceptance.Thi công hệ thống mặt trời áp mái cho nhà xưởng
