The quality of life of modern people is getting higher and higher. They are no longer satisfied with going to see the world with tour groups.More and more people like self-driving travel.Others enjoy hiking together to conquer nature.They carry their gear across deserts, mountains, rivers, and inevitably sleep in nature at night.Without electricity, how do you provide lighting, scare away wild animals, and indicate the location of the camp?The answer is solar-powered camping lights.
Where can I buy a solar-powered camping lamp?Professional sun lighting equipment mall (such as Fuxin network) can be bought, in addition to the hardware mechanical and electrical, metal building materials, hardware accessories stores can also be bought.As it relates to field use, quality must be guaranteed.So how do you buy a solar-powered camping lamp?Here are five tips for buying:
- Solar cells
The main function of solar cells is to convert light energy into electricity, a phenomenon known as the photovoltaic effect.There are three kinds of solar cells, monocrystalline silicon, polycrystalline silicon and amorphous silicon, which are more common and practical in many solar cells.In the eastern and western regions with abundant sunlight and good sunshine, it is better to use polysilicon solar cell.Due to the relatively simple production process and low price ratio of polysilicon solar cells, the conversion efficiency is constantly improving.In the southern region where there are more cloudy and rainy days and less sunlight, it is better to use monocrystalline silicon solar cells, because the electrical performance parameters of monocrystalline silicon solar cells are relatively stable.Amorphous silicon solar cells are better when indoor sunlight is weak because of amorphous silicon
Solar cells have low requirements for solar light conditions.
Above all, any solar lamp product we must understand solar cell first, solar cell has five big electric performance parameter, namely: short circuit current, peak current, open circuit voltage, peak voltage, peak power. For the average user, how do we know its five parameter values?A simple way to know this parameter is to test the 5 parameters with a multimeter in the sun at 12 noon (with a slight error in the measurement).
For a single solar cell, it is a PN junction, which has all the properties of a PN junction except that it produces electricity when the sun shines on it.It has a rated output voltage of 0.48V under standard lighting conditions. Solar cell assemblies used in solar lighting fixtures are composed of multiple solar cell connections.
Users can first look at solar cells to understand the price, performance and stability of solar lighting.I will introduce the charge and discharge controller, load, battery and so on.

As the input energy of solar photovoltaic power generation system is very unstable, so generally need to configure the battery system to work, solar lamps are no exception, must configure the battery to work.Generally, there are lead-acid batteries, Ni-CD batteries and Ni-H batteries. Their capacity selection directly affects the reliability of the system and the system price.The selection of battery capacity should generally follow the following principles: first of all, on the premise of meeting the requirements of night lighting, try to store the energy of the solar battery module during the day, and at the same time, store the electrical energy needed for continuous cloudy and rainy night lighting.The battery capacity is too small to meet the needs of night lighting.Storage capacity is too large, the battery is always in the state of power deficit, affecting the battery life, and cause waste.
Solar energy lamps and lanterns products to the advantage of energy conservation and environmental protection, of course, the load to save energy, long life.We generally use LED DIRECT current energy saving lamp and low pressure sodium lamp.
At present, most lawn lamps use LED as the light source. LED has a long life and can reach more than 100000h, and the working voltage is low, so it is very suitable for application in solar lawn lamps.Garden lights generally use LED and DC energy saving lamps.Dc energy-saving lamp voltage for DC, no inverter, convenient and safe.
Street lamps generally use low pressure sodium lamps.Low pressure sodium lamp light efficiency is high (up to 200LM/W) but low pressure sodium lamp price is expensive.
- Lamp housing
We have collected a lot of information about solar lamps abroad, and between aesthetics and energy saving, most of them choose energy saving.Lamps and lanterns exterior requirement does not want very tall, relative and practical go.At present, there are a lot of domestic lamps and lanterns with beautiful appearance and stainless steel shell.
