This is linked to the efficiency of the use of the components and the inclination angle of the installation.
If high efficiency modules are used, the installation angle is 40 degrees.
The spacing between square panels is calculated based on the principle that solar panels do not block. from 9:00 a.m. to 3:00 p.m. on the winter solstice.
Rule: 1 MW covers an area of 25,600 square meters = 38.4 acres = 2.56 hectares
20 MW is approximately 50 hectares
A solar street light occupies an area
Photovoltaic power plant, 100 MW requires an area of approximately 1350-1450 acres.
Technical principle
Solar energy is generated by the fusion of hydrogen and helium of hydrogen atoms at the interior of the sun to release enormous nuclear energy. Solar energy radiation. Most of the energy needed by humans comes fromdirectly or indirectly from the sun. Plants release oxygen, absorb carbon dioxide and convert solar energy into chemical energy and store it in the plant body through photosynthesis.
Fossil fuels such as coal, oil and natural gas are also primary energy sources formed by the evolution of ancient plants and animals buried underground over a long geological period. The energy contained in the earth itself generally refers to the energy related to the thermal energy inside the earth and the energy related to the nuclear reaction.
The energy linked to nuclear reactions is nuclear energy. When the structure of the atomic nucleus changes, it can release a large amount of energy, called nuclear energy, or nuclear energy for short, commonly known as atomic energy.
It comes from nuclear fission energy resources when uranium, plutonium, etc. stored in the earth's crust undergo fission reactions, and nuclear fusion energy resources when deuterium, tritium, lithium, etc. stored in the ocean undergo fusion reactions. These substances release energy when nuclear reactions occur. Currently, the main use of nuclear energy is electricity generation. In addition, it can also be used as other types of energy sources, heat sources, etc.
Solar energy is the energy generated by the continuous nuclear fusion reaction process inside the sun. The average intensity of solar radiation in Earth's orbit is 1369 W/㎡. The equatorial circumference of the Earth is 40,076 kilometers, so it can be calculated that the energy obtained by the Earth can reach 173,000 TW.
The standard maximum intensity at sea level is 1 kW/m2, and the radiation intensity annhe average over 24 hours at a certain point on the Earth's surface is 0.20 kW/m2, which is equivalent to 102,000 TW of energy. .

No more than 2 square meters. The height of the solar street light is about 3-8 meters, the battery capacity is 20-100Ah, and the area of the solar panel is 0.5-2 square meters, so the solar street light covers a area of no more than 2 square meters. When installing solar street lights, it is also necessary to consider the space and traffic conditions around the street lights to ensure the normal use and maintenance of the street lights.
