Lighting's factors affecting solar photovoltaic power generation:

1. Optimized design

The goal of system optimization is to inspect the actual solar intensity, light reflectance, external ambient temperature, wind power and the performance of each component of the photovoltaic power generation system and the interaction between them, so as to enable the photovoltaic power generation system to generate electricity. maximum. Some power stations lack optimal design and reduce power generation.

2. Equipment

The main equipment that affects power generation in photovoltaic power plants includes solar cell modules, combiner boxes, inverters and grid-connected infrastructure.

In the process of selecting components for power station construction, it is necessary to continuously optimize and match, mix the use of A-level and B-level solar cells, and consider the quality of the components; fully consider the actual latitude, spectrum, temperature, shelter, location, wiring, etc. The influence of operating conditions on the output of photovoltaic cells. During the installation and construction period, the enterprise needs to carry out fine management to avoid the phenomenon of delaying the construction period; it is necessary to select suitable and qualified auxiliary materials to ensure the quality of the project and avoid unnecessary power generation losses; to perform regular maintenance and ensure the intensity of supervision to ensure the photovoltaic power station normal operation.

3. Engineering quality

Some installers blindly reduce the project cost in order to earn higher profits, and the quality of the project may cause a loss of 3-6% in power generation.

3.1. Why doesn't the solar street light turn on?

(1) The solar street light has just been installed, and whether the switch is turned on.

(2) Whether there are obstructions when the solar panel absorbs sunlight, which makes it impossible to charge. If there are obstructions, please remove the obstructions or change the solar street light to a place without obstructions.

(3) In order to ensure the safety of transportation, we will keep the battery power at about 20%. If you find that the standby time is not long when you use it for the first time, please don't be surprised. After installing the lamp outdoors, the lamp can be fully charged. Meet the number of standby days.

(4) If the environment is brighter, the light sensing power of the lamp will work and the lamp will not light up. If you want the lamp to be bright, please cover the solar panel with a cover, and the lamp can be turned on after 5 minutes , If you want the lamps to turn on and off automatically, please install the solar street light where there is no light to the solar panel.

3.2. Why is my solar street light not bright enough?

(1) When leaving the factory, our lamps have only 20% power for storage and transportation safety. The built-in battery is insufficient and needs to be fully charged, and the brightness will become brighter.

(2) The ring mirrors installed in the lamps are different. For example, the lamps are installed in developed cities and the lights are bright everywhere. In contrast, the power of solar lamps is low and the brightness is not enough. If installed in a rural area, where there is no light pollution, the brightness will appear very bright and meet the lighting requirements of the road. Whether the lamp is in standby state, the power is 30% when there is no one, and the brightness will reach 100% when someone reaches the sensing area

(3) The scene used is wrong. Our lamps use street lamps with different powers according to different roads and installation heights. Some are professional-level road lighting lamps, which have requirements for light-emitting angle and brightness. Some are garden lights and landscape lights, which do not have such high requirements for brightness, so please confirm your installation environment when purchasing our products, and then confirm the power and shape of the lamps.

3.3. What is the reason for the short lighting time of solar street lights?

(1) The local or that day’s sunlight is insufficient or the sunshine time is short, the sunlight is weak, and the conversion efficiency of solar panels is low, resulting in insufficient charging, so the lighting time is short.

(2) The installation angle and direction are wrong. As we all know, solar panels need to be directly exposed to sunlight during photoelectric conversion. If there are special blocking features, even glass will greatly reduce the conversion efficiency of solar panels. In addition, when installing solar street lights, try to adjust the direction of the solar panels to the south. If there are obstructions to the south, please face the southwest or southeast. If the solar panels are facing north, the solar lights may not receive sunlight all day. , After our test, solar panels installed facing south will charge 30-50% more electricity than solar panels installed facing north.

(3) Seasonal weather reasons: In the second season of spring and winter, due to the short sunshine time in winter, weak sunshine in spring and many rainy days, it can not be fully charged. In summer and autumn, sunshine time is long and the sunshine is strong, which is a strong sunlight. It can fill the battery of the entire lamp, so sometimes, the lighting time in the second season of spring and winter is shorter than that of summer and autumn.

(4) Other objective factors: long installation time of solar panels, thick surface dust, snow on the surface, leaves on the surface, etc. will affect the photoelectric conversion efficiency of solar panels, so when there are problems mentioned above, please clean up the solar energy in time The cover of the board.

4. How long can the solar road lamp be on for a day?

The lighting time of a full day is affected by the solar panel of the lamp, the size of the battery, the use of the ring mirror and the intensity of the day's sunlight. If the strong sunlight can be fully charged in one day, it can meet the calibrated number of rainy days after being fully charged.

Design goals

Based on technology and humanities, it perfectly combines architectural culture and lighting art to create a warm and beautiful night landscape.

Lighting design principles

Practicality principle

Including the basic illuminance level required by the environment to meet the lighting needs. Consider the energy-saving, durable and convenient maintenance of lighting fixtures.

5

Principle of Integrity

Emphasize the integrity of the lighting environment, handle the relationship between the individual and the group, pay attention to the integrity of the individual lighting, balance the illuminance, light color and other lighting elements of each part of the light, implement zoning control, and make plans based on the characteristics of different locations Goals and control requirements.

The artistic principle uses a variety of lighting methods, illuminance, light color and lighting technology combinations such as lamp selection. In order to create a high-appreciation environmental landscape with a combination of points, lines and surfaces, and a clear and orderly rhythm.
