I disagree with what the brother said above. It is not very accurate to say that the optimal tilt angle is local latitude + 3. For example, Chongqing and Lhasa have the same dimensions, hence the installation tilt angles. photovoltaic solar modules do not have to be the same.
This question is a bit general. The installation tilt angle of the module depends on whether it is a grid-connected system or an independent system. Taking a network-connected system as an example, we should pursue a certain fixed. tilt angle and average maximum sunshine hours throughout the year. Zhejiang Photovoltaic Center The optimal angle of components should be between 19 and 28 degrees. The specific angle should take into account the supporting local climate of the structure (such as wind pressure, snow pressure). , etc.), appearance effect, etc.
Hello, the ba guardraillcon is a material that we will use when the decoration is almost finished. The balcony railing is an important element in the life of our furniture because it constitutes an important element of our interior communication with the exterior. world. Our choice of balcony decoration and railings is therefore particularly important. So, how much does a balcony railing cost per meter? What materials are balcony railings made of? Let's present it below. The following prices are for reference only. The price varies depending on the material you use. They are usually made of aluminum alloy, the price is around 250 per square meter and they are framed with glass. There are also cheaper ones, i.e. iron art. Depending on your needs, the price is about the same. What are the materials of balcony railings: 1. Ductile iron The only advantage of this type is its low price. Its resistance, its styleand its surface quality are very poor, so it is not suitable for balcony railings. 2. Zinc steel and galvanized steel are the same material but have different names. The advantages are good anti-corrosion, good safety performance, no rust, high strength, rich colors, many styles, affordable price and beautiful appearance. 3. Anti-corrosion wood: It is a good material for balcony railings. It is generally used in high-end villas and residences, and is rarely used in ordinary residences. Anti-corrosion wood has medium strength, monotonous style, and is prone to cracking and fading. 4. White steel is also called stainless steel. These two materials are generally divided into 202 and 304. The price difference between the two is almost half. The style of stainless steel is unique and the color is monotonous, so the pattern is not easyTHE. To distinguish. Generally speaking, 202 is easy to rust, so coastal cities generally use 304, while inland cities can use 202. 5. Aluminum alloy: the cost of this material is relatively high, and it is easy to scratch, which makes the maintenance cost high, so it is not commonly used. The above knowledge about balcony guardrails has been presented here. Here is a friendly reminder: do not place too large objects on the balcony, nor can you place dangerous and easy-to-fall objects such as flower pots. Additionally, care should be taken not to allow children to climb on the railings to avoid accidental or unnecessary losses. I hope my answer will be useful to you. If you find it useful, give me a thumbs up, I will respond more carefully in the future.
