Solar energy, as a “wonderful” existence, always gives people a sense of mystery of “being far and near” while saving energy and environmental protection.

Far away, solar energy can be applied to photovoltaic power stations in deserts, plateaus, and islands; Closer, it can also be used on residents’ photovoltaic roofs, photovoltaic RVs during travel, and the photovoltaic streetlights we see everywhere every day.

It is both distant and within reach.

Regardless of distance, solar energy is always present in every corner of our lives, bringing us the most perfect gift from nature.

Today, let’s talk about the most common solar application around us – solar photovoltaic street lights.

What should be noted when installing a solar street lamp？

Part 1: Photovoltaic Cells

At present, there are many types of photovoltaic cells on the market.
Special attention should be paid to the selection of solar street lamps in terms of photovoltaic cells. Only batteries with high conversion rate, strong stability, and a peak output power below 0.05 meet the standard.

Part 2: Battery aspect

The battery is an important component of the photovoltaic lighting system and an indispensable energy component in the entire system.
The battery can store electrical energy in sunny conditions during the day, ensuring that solar street lights can continue to supply power even in low light conditions (such as cloudy days and nights).

Batteries are usually charged using a cyclic working method. During AC power outages, batteries need to play a leading role.

Part:3 Controller aspect

According to relevant research, the charging efficiency of photovoltaic lighting system is mainly affected by the current size, pulse period, charging time and other factors of the battery.

The controller can control the current level based on the amount of stored charge in the battery. If the battery level is around 90%, the controller will immediately respond accordingly.

Optimizing the application of the controller requires implementing non heating stage charging management to ensure adjustable settings throughout the entire process.

Part:4 Light source aspect

According to the different places where the light source is used, green light sources that meet national standards such as light efficiency and lifespan can be selected.

The photovoltaic lighting system mainly selects green light sources with higher light efficiency, longer lifespan, and no flicker. Such as LED light source, Induction lamp and fluorescent lamp.

From the perspective of sustainable development, LED light sources have greater potential for development and will become mainstream light sources in future development.

Part:5  Cable aspect

Choosing the appropriate cable is an important step in the application of photovoltaic lighting systems, and multiple factors should be considered to select the appropriate cable.

Cables with a line loss of no more than 0.05 can be selected by calculation, with line loss=current × Circuit bus length × Cable voltage factor.

In addition, during operation, the output of photovoltaic cells will be affected by the connecting cables. When applying photovoltaic cells, if you want to maximize the power generation efficiency of photovoltaic cells, you must connect the cables correctly.
