The main factors affecting solar radiation

The wind-solar hybrid street lamp is a power generation lighting system that generates power from two power generation equipment, wind turbine and solar cell array. Wind-solar hybrid street lights are the field of new energy utilization. This system effectively improves the situation of insufficient wind energy or insufficient conversion rate of solar panels, which leads to insufficient charging and cannot guarantee normal lighting.

Compared with traditional street lamps, wind-solar hybrid street lamps use renewable solar energy and wind energy in nature as energy sources, do not emit polluting gases into the atmosphere, and are more green and environmentally friendly. It not only achieves environmental protection, but also avoids large amounts of electricity expenses in the future cost. Wind-solar hybrid street lights, because each street light is an individual, does not need to lay cables, and does not require large quantities of electrical equipment, which saves manpower and money, and can avoid large-scale power outages caused by failures such as power supply systems. However, in use, attention should be paid to the noise impact of wind power generation and timely maintenance.

The main factors affecting the strength of solar radiation are as follows:

1. Latitude position

The low latitude means that the solar altitude angle is large at noon, and the distance of solar radiation through the atmosphere is short, and the amount of solar radiation reaching the ground is less when it is weakened by the atmosphere; otherwise, it is less.

2, weather conditions

In sunny weather, due to the small and thin cloud layer, the weakening effect of the atmosphere on solar radiation is weak, and the solar radiation reaching the ground is strong; in rainy weather, due to the thick and large cloud layer, the weakening effect of the atmosphere on solar radiation is strong. The solar radiation on the ground is weak. For example, the equatorial area is controlled by the equatorial low pressure zone, and there is more convective rain, while the subtropical area is controlled by the subtropical high and the weather is mostly sunny. Therefore, the solar radiation in the equatorial area is weaker than that in the subtropical area.

3, altitude

High altitude, thin air, the weakening effect of the atmosphere on solar radiation, the solar radiation reaching the ground is strong; otherwise, it is weak. For example, the Qinghai-Tibet Plateau is the region with the strongest solar radiation in our country for this reason.

4. Length of sunshine

Long sunshine time, strong solar radiation; short sunshine time, weak solar radiation. For example, the summer in my country is generally high temperature between the north and the south, and the temperature difference is not large, because the higher the latitude area, the longer daytime, which makes up for the energy loss due to the low solar altitude.

5, other

(1) Transparency of the atmosphere: If there is a lot of dust in the air, the intensity of solar radiation will be weak.

Topography:

(2) Slope: sunny slopes get more; shady slopes get less. The leeward slope may get more solar radiation due to less precipitation, and the windward slope may get less solar radiation due to more precipitation.
