How to install solar energy system on roof? Việt Nam

With the development of the new energy industry in recent years, photovoltaic power generation has become more and more popular around the world. In the past, photovoltaic power generation was generally built on the ground. With the rise of the distributed photovoltaic power generation market, the value of various types of rooftops has emerged.

Many people have the idea of installing solar energy system, but they often cannot make a good judgment on how many kilowatts of system they need to install and what kind of photovoltaic panels are suitable for their roof. Next we will explain it to you.

Is your roof suitable for solar energy system?

We first need to know your daily electricity usage to determine how many kilowatts of system you need, and then determine whether your roof is suitable for installing photovoltaic panels. We need to know the material and load-bearing capacity of your roof to determine how many pieces of photovoltaic panels can be installed. If the roof cannot bear the load, it is generally recommended to install it on the ground.

If you want to install solar energy system on the roof, but the roof cannot bear the load, there is another type of photovoltaic panel you can consider, that is, flexible solar panels. Compared with ordinary solar panels with back sheets, although the single-piece cost is higher, it is lighter in weight, fits better on the roof, and has cheaper shipping costs. Therefore, its total cost is no more expensive than ordinary photovoltaic panels.

Special roofs can also be equipped with solar energy system

If your roof is special, for example, its surface is not flat but curved. In this case, if you want to install a solar energy system, you can choose flexible photovoltaic panels.

The flexible photovoltaic panel uses ultra-thin silicon wafers and advanced organic polymer packaging materials. It can be bent. Its bending radius can reach a minimum of 0.30m and can perfectly fit various arc shapes. There is no need for brackets during installation, so the installation efficiency is higher than that of ordinary photovoltaic panels, and it can also fit well on curved roofs.

Its weight is only about 30% of traditional photovoltaic panels, and the module efficiency is about the same. With a thickness as thin as 1.7mm, it can also meet the installation needs of photovoltaic systems on various roofs with insufficient load-bearing capacity.

Our flexible photovoltaic panels can be customized according to your needs and also support sampling, so its application scenarios are not only roofs, but also can meet the needs of various special application scenarios.

Wide range of applications for rooftop solar energy system

Photovoltaic panels installed on the roof save space, so they are favored and chosen by more and more customers. Some of its main application scenarios:

1. Roofs of large enterprises and factories with high energy consumption and clear property rights. Such enterprises or factories have stable operations and high energy consumption. Their roofs have a long life cycle and can ensure long-term stable operations. They are suitable for the development of large-scale rooftop power stations above megawatts.

2. Roof of agricultural greenhouse. The combination of agriculture and photovoltaic power generation has become the focus of industry development. Photovoltaic modules are laid on the roof of the greenhouse, which does not occupy land resources and can also bring secondary benefits to users.

3. Roofs of residential buildings, villas, etc. In urban areas, you can often see single-family buildings and villas, which can adopt the "self-generated electricity for personal use and the surplus electricity grid model".
