Today, with the explosive growth of distributed photovoltaics, photovoltaic power plants have long been known to every household. However, there are many brands on the market, and the quality of the products is uneven. When choosing, will you step on the pit?

What are the errors?

Let's see how many of you have been recruited?

Myth 1: The bigger the installed capacity, the better

　　Reason: orientation, inclination angle, spacing, load

　　1. Component orientation: The ideal installation azimuth is due south. If it is not in the south, the power generation will be greatly affected, so it is not suitable for installing photovoltaic power plants around the roof.

　　2. Module inclination: the optimal inclination of the system is similar to the local latitude angle, or according to the roof structure, the modules are laid parallel to the roof slope, and the inclination can be measured by using an angle measuring instrument.

　　3. The spacing between the front and rear rows of the module: the spacing should ensure that the solar cell array is not blocked from 9 am to 3 or 4 pm on the winter solstice. So if you want high power generation, you must control the spacing.

　　4. Load: The bearing capacity of the building is limited, and it is not possible to blindly pursue overloading due to the arrangement of too many components, otherwise there will be potential safety hazards.

Myth 2: The lower the unit price, the better

　　Reason: Value determines price, supply and demand affect price

　　Photovoltaic power plants are used outdoors for a long time, and they must not only withstand violent storms (snow), but also be exposed to the sun. These day-to-day tests are directly related to the power generation efficiency of photovoltaic power plants, and have a direct impact on the return on investment of consumers. The following are some common low-cost photovoltaic products in the photovoltaic market:

1. Low conversion rate of photovoltaic modules and inferior components

　　There are still many differences in the grade of solar panels on the market, defective products, etc. When customers do not know how to choose good solar energy, it is easy to buy inferior components, etc.

2. Insufficient thickness of bracket and insufficient galvanized thickness lead to rust

　　The support condition of the photovoltaic power station is closely related to the service life and safety of the power station. According to the material, the bracket can be divided into three types: galvanized steel bracket, aluminum alloy bracket, and stainless steel bracket. Galvanized steel is the most commonly used and the most cost-effective. For customers who pursue aesthetics and do not require high strength, aluminum alloy brackets can be used, but the cost is slightly more expensive; while for customers who pursue aesthetics and have higher requirements on strength, stainless steel brackets can be used, but the cost is the most expensive.

　　In the market, the thickness of steel is often not enough (1.5mm), the strength is not enough, and the power station is easily destroyed by strong winds.

　　The galvanized thickness is not enough, or electroplating is used instead of hot-dip plating, and the rust resistance is very poor.

　　For customers who use C-shaped steel brackets, the steel thickness is generally 2.0mm, and the hot-dip galvanized anti-rust treatment is used. The galvanized thickness is generally 60um. In typhoon-prone areas, the steel thickness should be increased to 2.5mm, and in coastal areas with severe salt spray erosion, the galvanized thickness should be increased to 80um or 100um.

3. Cable problem

　　Cables are also an important part of photovoltaic power plants, which are equivalent to various blood vessels of the human body. Once unqualified or inferior cables are used, no matter how good the component inverter is, it cannot efficiently transmit the generated electricity, and the power generation efficiency of the entire power station will be greatly reduced. Some power stations do not even use photovoltaic special cables.

4. The load of the cement pier is not enough

5. Parts are easy to rust

　　Therefore, it is not that the lower the unit price, the better. When purchasing, consumers should shop around and consider the quality of the power station in addition to the price. After all, only a good power station can protect your income.

Misunderstanding 3: After the power station is installed, you don’t need to worry about it

　　If you want your own photovoltaic power station to generate electricity efficiently, daily operation and maintenance are indispensable.

　　1. Clean the power station with a mop dipped in clean water, check the stability of the screws of the power station and the integrity of the cables, once every six months.

　　2. The metal drainage desilter is specially designed for low-angle installation of solar panels (photovoltaic modules), and completely eliminates the accumulation of water, ash, muddy water and mud belts that block the cells at the lower frame of the module, and increases the power generation of the system. The investment cost of the entire drainage desilter can be recovered in one month.

　　3. Monitoring APP. Today's photovoltaic power stations can be monitored 24 hours a day through the mobile phone monitoring APP. Open the APP at any time to check whether the power station is running normally, and the power generation data.

　　Choose a reliable brand

As the saying goes, "The tree that hugs is born from the end of the millennium; the platform of nine layers starts from the soil." To make a photovoltaic power station generate electricity efficiently, the quality of the power station is the key. Choose a reliable and powerful brand photovoltaic manufacturer, so that you can avoid detours!
