Under the guidance of the national new energy strategy and policy support, the concept of developing green energy has permeated the public consciousness. With the advancement of science and technology, the cost of building photovoltaic power generation installations continues to decline. Nowadays, an increasing number of people are installing solar photovoltaic systems on their roofs, regardless of the exalted nature of their thoughts. The question on everyone's mind is: How much benefit can investing in residential solar photovoltaic power generation bring?
Many friends who have installed home solar photovoltaic power generation systems have expressed that the power generation effect of the domestic photovoltaic power stations is not good, and there is a significant gap from the ideal efficiency. Could it be because the installation angle of the photovoltaic panels is not?Please provide the Chinese content to be translated.Jia Qian Jiao?
The angle of inclination for residential photovoltaic power generation is not a myth. In a narrow sense, the so-called optimal angle refers to the inclination that the photovoltaic panels receive...No Chinese content provided, original return: No translation needed.The angle of the sun's radiation. It is a factor affecting the efficiency of photovoltaic power generation, but in actual operation, it is not a determining myth. Moreover, the optimal tilt angle is inherently a dynamic value, and the installation environment of residential photovoltaic power generation systems varies greatly. Even if you takePlease provide the Chinese content to be translated.A good way to install, and the income will also be quite different.
The tilt angle of residential photovoltaic power generation systems can affect efficiency, but it is generally negligible. The installation company will consider and select an appropriate installation angle.
For residential solar power generation, since the installation trend of solar panels is not a myth, what factors greatly influence the income? The following three often overlooked factors are particularly important.
1. Obstruct
"If I cover 150 square meters of solar panels, it's no big deal." That's a mistaken notion, as I'm not well-versed in photovoltaic power generation systems. A small amount of virtual shading won't have a significant impact, but even a slight real shading may result in a 10% loss, or even damage the photovoltaic power generation equipment, which directly leads to a decrease in revenue.
2. Towards
Residential photovoltaic power generation typically relies on the installation of solar panels on houses. Although the majority of houses in China face north-south, there are many that face east-west. Additionally, with the diversification of architectural styles, multi-sided villa roofs are also quite common. If the focus of residential photovoltaic power generation is on income, it is not recommended to install solar panels on the east, west, or north sides; instead, they should be installed on the south side or at an angle of about 15 degrees off the true south.
3. Safety
At any time, the importance of safety in production surpasses that of profits. Without safety, how can we even talk about profits? Some residential photovoltaic power generation systems are installed on roofs at the 2nd and 3rd floors, while others are on the 20th and 30th floors. Improper installation poses significant safety risks.
1. Design was not reasonable, such as in pursuit ofPlease provide the Chinese content to be translated.Optimal tilt angle installation at more than 30 degrees results in a 10-meter long photovoltaic array requiring a support height of 6 meters, which places high demands on the building and steel frame structures of the roof. Roof photovoltaic power plant collapses occur frequently.
2. Many families have installed photovoltaic power generation without considering the later maintenance. The solar panels cover the entire roof, with some having to protrude out, just like buying a house, occupying as much space as possible. As we all know, maintenance can be quite challenging. Don't believe the nonsense that "photovoltaic power generation requires no maintenance or cleaning." A pile of bird droppings can destroy the entire power station. This is not an exaggeration.
