5 Useful Tips Of Choosing Hight Quality Solar Powered Street Lamp In China

Solar street light is powered by crystal silicon solar cell, take maintenance-free lithium battery, ultra-bright LED lamps as light source, and controlled by intelligent charge and discharge controller, no cable laying, simple subsequent installation.Solar street lamp uses DC power supply,no AC power supply need , no electric cost.

But because there has been no specific industry standards for solar lamps in the solar lighting market, many friends often ask how to choose a good quality solar powered street lamp.

As a professional outdoor led lighting manufacturer with more than 10 years solar street lamp R&D,production experience in China,EXC streetlight will share the following 5 aspects of choosing high quality solar street lighting lamp useful tips:

Solar panels

Common solar panels in the market are polycrystalline and single crystal, which can be directly judged from the appearance. 70% of solar panels on the market are polycrystalline, with a blue ice flower on the surface, while single-crystal panels are a solid color.

Polycrystalline silicon cells have lower conversion efficiency.The average conversion efficiency of monocrystalline silicon cells is about 1% higher than that of polycrystalline silicon.But because monocrystalline silicon cells are only quasi-squares (arcs on each side), there is part of area can not be filled up enough when combined into solar panels. While polysilicon is square, so there is no such problem.

Storage battery

Lithium iron phosphate batteries (lithium batteries) are recommended.The other is lead-acid,lead-acid batteries are not resistant to high temperatures and prone to leak .Lithium batteries are resistant to high temperatures, but relatively dose not resistant to low temperatures.So choose storage battery based on the region.In general, the conversion rate and safety of lithium batteries are higher than those of lead acid batteries.

Using lithium iron phosphate batteries, charging speed will be faster, safety factor is high, are more durable than long-life lead-acid batteries, the service life will be almost six times more than lead-acid batteries.

Controller

Now there are many controllers on the market, EXC streetlight recommend the controller with new technology, such as MPPT control.At present, the best MPPT controller in China is the solar controller produced by EXC technology, using MPPT charging technology, so that the efficiency of solar power generation system promoted 50% than the traditional one, so as to achieve efficient charging.

Lighting source

Choosing high-quality lamp bead.Lamp bead directly affects the illuminance of the solar powered street lamp, stability etc, which is an extremely important factor.Riya lamp bead is recommended.Energy consumption is 80% less than the same light efficiency incandescent lamp, stable and uniform light source without flicker, high efficiency and energy saving, low heat, high color rendering, long service life, high luminous efficiency.

Lamp shell

Common lamp shell in market is hot dip galvanized and cold galvanized, can be judged by naked eye.Hot dip galvanized has coating on the incision, cold dip galvanized has no coating on the incision.The common lamp shell basically is hot dip galvanized in market, mainly due to the hot dip galvanized is more anticorrosive rust prevention than cold.

Choosing big brand well-known solar street lamp manufacturers, such as EXC street light, often can guarantee in many aspects, after sale is also convenient.Such as: professional production equipment, testing equipment and automation equipment, technical team and so on, can reduce the buyer's worries.
