Installing rooftop solar power systems is becoming a popular trend, bringing many benefits not only to the environment but also to families and businesses.
Since 2019, the solar energy industry has had a major turning point, receiving positive attention from the community. And many solar power projects have been deployed from household scale to solar power plants, contributing to reducing dependence on traditional energy and helping to ensure a stable energy supply in the future.
In this article, VREnergy explains to you the rooftop solar power installation solution in detail!
Energy solutions for buildings
Installing solar power on rooftops is an effective sustainable energy solution for providing electricity to commercial buildings, hospitals, schools and other structures.

Rooftop solar power systems for buildings have become popular in 2019, especially with the 2023 rooftop solar power policies from the Prime Minister’s Circular promoting many practical benefits. electricity demand.
To provide energy for the building, reduce dependence on traditional power sources and save monthly energy use.
So what are the benefits of installing rooftop solar power for buildings?
Benefits of installing rooftop solar power
Solar panel systems absorb and convert sunlight into electricity through inverters. Rooftop solar power systems are considered the most effective energy solutions to help buildings proactively source energy effectively:
- Minimize electricity costs: Rooftop solar power systems can provide electricity to the building, helping to reduce electricity costs for users.
- Environmental protection: Solar power is a clean energy source, does not emit emissions that pollute the environment.
- Enhance property value: Rooftop solar power systems can help increase the property value of the building.
Cost of installing rooftop solar power

The decision to install rooftop solar power requires careful consideration of important cost factors such as system capacity, equipment quality, and installation costs.
While the initial cost can be a challenge, looking ahead, this investment often brings economic and environmental benefits in the long term, helping to reduce energy costs and contribute to environmental protection. .
- System capacity: The larger the system capacity, the higher the installation cost.
- Equipment & supplies: Better quality solar panels will cost more.
- Solar power installation and construction price: Labor price for rooftop solar power installation may vary depending on the area.
About system capacity

System capacity is a factor that directly determines the system’s ability to produce energy. Power is measured in kilowatt peak (kWp), and costs typically increase with power.
Homes or businesses with larger energy needs will need to install higher capacity systems, which can increase initial costs.
About equipment & supplies

The quality and type of equipment used in a solar power system also affects the installation cost. Specifically, the main components in the system are:
- Solar panels .
- Power converter (inverter).
- Other accessories have different prices.
All equipment and materials of the solar power system are used for a long time, moreover, the higher the conversion efficiency , the more expensive the price.
Price for installation & construction of solar power system

Installation and construction costs include labor and costs related to the system deployment process. Includes installing devices, connecting systems, and ensuring that every component functions properly.
Factors such as roof topography, system size, and local conditions can affect installation costs. Therefore, before implementing the project, we need to survey the area where the solar power system will be installed to determine the feasible installation location, light direction, and highest conversion efficiency.
Procedures for installing rooftop solar power
After completing the solar power system, we need to carry out procedures to apply for installation of 2-way electricity meters , record electricity output and buy and sell solar electricity to the electricity company.
To install rooftop solar power, investors need to carry out the following procedures:
- Registering a rooftop solar power project : Investors need to submit a rooftop solar power project registration application to the Department of Industry and Trade.
- Sign a power purchase contract with the Electricity Company: After project approval, the investor needs to sign a power purchase contract with the Electricity Company.
- Installing solar power systems: Investors need to hire a professional unit to install solar power systems.
- Connection license: After installing the solar power system, the investor needs to apply for a connection license to the grid.
