400x1000 photovoltaic panel with what battery and light?

Photovoltaic panel is a device that can convert solar energy into electricity, common sizes include: 1000x1000mm, 1000x1200mm, 400x1000mm and so on. Different sizes of photovoltaic panels are suitable for different scenarios, and under the size of 400x1000, it is very important to choose the right battery and lamps.

Battery selection

In 400x1000 photovoltaic panels, there are generally three kinds of batteries used: nickel-metal hydride batteries, lithium batteries and lead-acid batteries.

1. Nickel metal hydride battery

Nickel-metal hydride batteries have higher specific energy, can be recharged more times, storage environment requirements are low, but the price is relatively high. Its long service life is suitable for use in some high-end solar lighting products, such as street lights, advertising light boxes, lawn lights, etc.

2. Lithium battery

Lithium batteries have high energy density, no memory effect, and low self-discharge rate, which are suitable for use in high extreme environments, but the price is higher. Its life is short, generally 2/3 to 3/4 of the nickel metal hydride battery, but because of its small size, light weight, large capacity, in some need of light, easy to carry solar lighting equipment has been widely used, such as outdoor solar mobile power, flashlights and so on.

3. Lead-acid batteries

Lead-acid batteries have low price, large capacity, but large weight, high storage environment requirements, high self-discharge rate, poor sealing and other shortcomings. Due to its low price, it is suitable for use in some low-end solar lighting products, such as solar household lights, solar garden lights and so on.

Selection of lamps

When choosing solar lamps, you need to choose different lamps according to different scenes, which can be roughly divided into street lights, lawn lights and solar household lights.

1. Street lights

Street lamp is a widely used solar lighting equipment, generally need to use a high brightness lamp head, with enough photovoltaic panels and battery packs, can provide enough lighting at night. In the 400x1000 photovoltaic panel, it is recommended to choose high-end batteries such as nickel-metal hydride batteries and lithium batteries, with high brightness LED lamp heads, and including charging controllers, inverters and other equipment.

2. Lawn lights

Lawn lights are a kind of solar lighting equipment widely used in outdoor landscape lighting, generally using low-brightness LED lamp heads, at night for roadside lawns, gardens, etc., to provide sufficient lighting effects. Its photovoltaic panels, battery packs and other additional equipment are relatively simple, you can choose relatively inexpensive lead-acid batteries and solar household lights.

3. Solar home lights

Solar household lamp is a kind of convenient and easy to use solar lighting equipment, generally used to provide light source in outdoor environment. Its photovoltaic panel size is not large, you can choose a relatively cheap lead-acid battery, with a low power LED lamp holder can be. In family use, generally also need to take into account.
