Users who install solar panels must hope to receive more sunlight. The installation position of solar panels is not good enough, and the obstruction of surrounding trees and other obstacles can affect the reception of light. If solar panels cannot guarantee to always face the sun, we cannot help but doubt whether they are worth investing.

事實(shí)上，雖然有些因素會(huì)影響太陽(yáng)能電池板的發(fā)電效率，但可再生能源技術(shù)在大多數(shù)條件下都可以工作。太陽(yáng)能電池板的發(fā)電效率和安裝的位置有很大關(guān)系。本文將介紹用戶(hù)如何根據(jù)自身情況，確定太陽(yáng)能電池板的佳位置。

In fact, although some factors can affect the power generation efficiency of solar panels, renewable energy technologies can work under most conditions. The power generation efficiency of solar panels is closely related to their installation location. This article will introduce how users can determine the optimal location for solar panels based on their own situation.

為什么太陽(yáng)能板的安裝位置很重要？

Why is the installation position of solar panels important?

光伏太陽(yáng)能板通過(guò)吸收陽(yáng)光發(fā)電。太陽(yáng)能板除了直接吸收太陽(yáng)光，還會(huì)收集其他地方反射的陽(yáng)光。

Photovoltaic solar panels generate electricity by absorbing sunlight. Solar panels not only directly absorb sunlight, but also collect sunlight reflected from other places.

因?yàn)樘?yáng)光的主要來(lái)源是太陽(yáng)光直射，所以找到太陽(yáng)能板的佳安裝位置，使其能夠大限度地暴露在陽(yáng)光下很重要。理想情況下，光照應(yīng)和太陽(yáng)能板表面垂直。但同時(shí)還需要考慮，用戶(hù)居住地點(diǎn)不同，太陽(yáng)光照射角度變化這兩個(gè)因素。

Because the main source of sunlight is direct sunlight, it is important to find a suitable installation location for solar panels that can be exposed to maximum sunlight. Ideally, the light should be perpendicular to the surface of the solar panel. But at the same time, it is also necessary to consider two factors: different residential locations of users and changes in the angle of sunlight exposure.

太陽(yáng)能板的朝向

Orientation of solar panels

太陽(yáng)能板的佳朝向和用戶(hù)居住的半球位置有關(guān)。如果用戶(hù)住在赤道以北地區(qū)，那么太陽(yáng)能板好應(yīng)該朝南。這是因?yàn)樘?yáng)直接照射在赤道上，所以如果居住在赤道以北地區(qū)，讓太陽(yáng)能板朝南，那么它就能夠在未來(lái)一年內(nèi)大限度地暴露在陽(yáng)光下。

The optimal orientation of solar panels is related to the hemisphere location where the user resides. If the user lives in an area north of the equator, the solar panels should face south. This is because the sun shines directly on the equator, so if you live in the area north of the equator and have the solar panels facing south, it can be exposed to sunlight to the maximum extent in the next year.

如果用戶(hù)住在南半球地區(qū)，那么情況正好相反。太陽(yáng)能板應(yīng)朝北，這樣一整年都可以暴露在陽(yáng)光下。

If the user lives in the southern hemisphere, the situation is exactly the opposite. The solar panels should face north so that they can be exposed to sunlight throughout the year.

這是有利于全年太陽(yáng)能發(fā)電的佳策略，但是除此之外還有在高峰時(shí)間段大限度利用太陽(yáng)能的方法。如果您的供電商使用分時(shí)計(jì)價(jià)，在高峰時(shí)段電價(jià)較高，用戶(hù)可以安裝面朝西的太陽(yáng)能板減少開(kāi)支。觀察發(fā)現(xiàn)，面朝西的太陽(yáng)能在高峰時(shí)段的發(fā)電量比朝南的替代產(chǎn)品多50%。

This is a good strategy for year-round solar power generation, but there are also ways to maximize the utilization of solar energy during peak hours. If your power supplier uses time-of-use pricing, during peak hours when electricity prices are high, users can install solar panels facing west to reduce expenses. Observations have found that solar energy facing west generates 50% more electricity during peak hours than alternative products facing south.

太陽(yáng)能板的角度

The angle of the solar panel

但是，太陽(yáng)能板的安裝位置也不是唯一決定因素，其安裝角度也會(huì)影響效率。調(diào)整安裝角度是為了讓陽(yáng)光垂直照向面板，盡可能多地獲取太陽(yáng)能。盡管某些類(lèi)型的屋頂可能會(huì)有一定限制，但是面板的角度通常都可以在安裝過(guò)程中修改。

However, the installation position of solar panels is not the only determining factor, and their installation angle also affects efficiency. Adjusting the installation angle is to allow sunlight to shine vertically on the panel and obtain as much solar energy as possible. Although certain types of roofs may have certain limitations, the angle of the panels can usually be modified during installation.

將傾斜角度設(shè)置為與用戶(hù)所在地理緯度相同的角度，則是找到太陽(yáng)能板佳角度的一個(gè)常見(jiàn)方法。舉個(gè)例子，如果用戶(hù)處于緯度40度的地區(qū)，那么太陽(yáng)能板的角度也為40度。冬季時(shí)期，建議面板傾斜度應(yīng)高于地理緯度15度，這能夠進(jìn)一步提高太陽(yáng)能板的效率。

Setting the tilt angle to be the same as the user's geographic latitude is a common way to find the optimal angle for solar panels. For example, if the user is in an area with a latitude of 40 degrees, the angle of the solar panel is also 40 degrees. During winter, it is recommended that the panel tilt should be 15 degrees higher than the geographic latitude, which can further improve the efficiency of solar panels.

找到安裝太陽(yáng)能板的理想朝向和角度將有助于提高它們的整體效率和發(fā)電能力，但是不要過(guò)于追求完美。無(wú)論用戶(hù)居住在哪個(gè)地區(qū)，或者面板朝向如何，安裝屋頂太陽(yáng)能板都非常有用。

Finding the ideal orientation and angle for installing solar panels will help improve their overall efficiency and power generation capacity, but do not overly pursue perfection. Installing rooftop solar panels is very useful regardless of the region where the user resides or the orientation of the panels.
