Nowadays, many people like to buy
Solar Road Studs and place them in the yard of their garden, which saves electricity and is very convenient to install, no wiring, just install a few screws. However, there are many kinds of
Solar Road Studs on the market, some look exactly the same, but the price is almost the same, why is this? How can I know the quality of
Solar Road Studs? In my opinion, there may be three aspects that determine
Solar Road Pros and cons of Studs:
First: charging capacity
The capacity of the photovoltaic panel is directly related to the charging capacity. The capacity of the photovoltaic panel refers to the power of the photovoltaic panel, which is equal to the efficiency of the photovoltaic panel and the area of the photovoltaic panel. That is to say, the capacity of the photovoltaic panel is only one aspect, and the efficiency is not high, or If the silicon wafer has dead chips, it is meaningless. The efficiency of photovoltaic panels on the market is currently around 120W-180W/square. Some manufacturers choose B-grade silicon chip packaging, which is not very efficient. Although the photovoltaic panels look large, The actual output is not high.
Second: power storage
The only indicator of power storage is the battery, which is the deepest place in the industry. Because the appearance is the same, the capacity is completely different, and ordinary consumers cannot measure the capacity of the battery at all. As for the currently used
Solar Road Studs battery, it is determined that the battery is good. The bad ones can be roughly divided into the following points:
The actual capacity of the capacitor, maybe the battery with the 32650 logo is a 5AH section, but according to the results of the market spot check, the actual capacity is 3AH-5AH section, even the theoretically designed capacitor can not reach, this is why Many lights do not light up after two or three hours, or the reason why they are fully charged after three or four hours of charging is caused by insufficient capacity.
Resistor internal resistance,
Solar Road Studs battery is a battery pack composed of multiple batteries. The two resistors are generally connected in parallel. At this time, if the internal resistance of the two batteries is different, an internal cycle will be formed, and the power consumption capacity will first cause Insufficient output will seriously affect the life of the battery. That is to say, no matter how good the battery is, if it is not assembled in strict capacity, it will become the result of "three monks have no water to drink".
Battery protection, in order to save costs, many
Solar Studs batteries are not installed with guard plates to protect charging and discharging, it is very easy to overcharge or overdischarge, and finally the battery enters a dead state and cannot work normally, which is why many lamps cannot be used for a period of time. The main reason for not being able to charge.
Third: waterproof construction process of lamps
After all,
Solar Studs is a kind of outdoor lamps. In the sun and rain environment, the waterproof and moisture-proof technology of lamps is very important. As far as the current
Solar Studs manufacturers are concerned, many manufacturers do not have the production experience of outdoor lamps. The ability is not strong enough, and it is not waterproof. It is easy to enter the water when it rains, which will cause damage to the internal components. More importantly, it is moisture-proof. Many manufacturers do not care about it. I do not know that in a humid environment, the components will rust, or outdoor mosquitoes will invade your hands. Substances are secreted in it, which directly corrodes the control board or PCB, etc., and eventually causes the lamps to fail to work properly.
The above are several important factors for judging the quality of
Solar Studs.
