The price of solar led street light

The deficiency of the solar street light price high solar street lamps, initial investment is large, the total cost is the same one solar street lamps power 34 times of the normal street lamp; Energy conversion efficiency is low, solar photovoltaic battery conversion efficiency is about 15% ~ 19%, and in theory the conversion efficiency of silicon solar cell

the deficiency of the solar street lamps

solar street light price is high, initial investment is large, the total cost is the same one solar street lamps power conventional street 3. Four times; Energy conversion efficiency is low, solar photovoltaic battery conversion efficiency is about 15% ~ 19%, the theory of silicon solar cell conversion efficiency can reach 25%, but may be caused by surrounding buildings block after the actual installation efficiency is lower.

the solar cell area is 110 w/m2, 1 kw solar cell area of about 9 m2, such a large area of it is almost impossible to fixed on the light pole, so for the expressway, the main still not apply; Influenced by geographical climate conditions, due to rely on the sun to provide energy, the local climate weather conditions directly affect the use of street lamp.

rainy day is too long can affect lights, cause the illumination brightness or could not reach the requirements of national standards, appear even not bright lights.

the price of battery and the controller is higher and the battery is not durable, must be replaced periodically, the service life of the controller is generally only 3 years, because of too much affected by the outside factors such as climate results in the decrease of reliability.

solar street lights maintenance difficulties, panels, the heat island effect of quality control testing, life cycle is not guaranteed and can't be unified control management. May not appear lighting conditions at the same time; Light narrow range.
