1. Look at the panel size
When choosing solar energy, we need to choose the appropriate panel according to the space size and actual needs. There are 19*22cm, 24*35cm, 35*35cm, 35*46cm and other common specifications in the market. The power and conversion rate of Myanmar Communist Party of different specifications are different. It is generally recommended to choose more than 18%.
2. Point battery size
The solar lamp absorbs heat through the panel, then stores it in the battery, and drives the lamp to shine when needed, so the size of the battery is also very critical. The larger the battery capacity is selected, the longer it can last. In addition, there is the number of batteries. The basic model is 1. If you want to have a long battery life, it is recommended to choose 3 or 4 batteries.
3. Look at the number of lamp caps
Generally, the lamp caps of solar lamps have multiple lamp beads in the main city. The more the number of lamp beads, the more brightness the lamps emit. If users do not know how many lamp caps they need, they can consult the merchants. In addition, the panel of the lamp cap is also very important. You need to choose one with good light transmittance, so as not to affect the brightness of the sun lamp.
4. Look at the material of the lampshade
There are many kinds of solar lamps on the market. According to the materials, there are plastic lamps and metal lamps. Generally, the price of plastic lamps will be much cheaper. However, because the heating condition of lamps is serious, it is recommended to choose aluminum alloy lamps, so that the performance is more stable and the service life is longer.
5. Look at the performance of lamps
Because many solar lamps are used outdoors, when purchasing them, they must have waterproof and lightning protection effects, otherwise electric shock accidents are likely to occur in thunderstorms. In addition, in order to ensure the lightning protection effect, good grounding is required when installing solar lamps.
