30w LED solar street light

The emergence of more and more solar lights on both sides of the road, then we how to choose the right solar lights configuration? Now I calculate the rough. Suppose we need is a 30w light source, daily illumination time is 5h (eight p.m. - eleven in the evening, at five o'clock to seven in the morning), rainy days to ensure that the number of days five days, then what we need is to configure it? First, calculate the actual current I = 30w / 12v = 2.5A so that you can roughly calculate the battery capacity = 5h * 2.5A * (5 + 1) = 75Ah The actual battery capacity is slightly larger than the actual computing is about 80Ah accepted in accordance with the average daily light exposure time is four hours computing power panels nearly as 60wp so we are according to customer needs, and help customers to find the best installation, you want to design a specific configuration selected in accordance with local conditions and reduce unnecessary waste. Works solar street works Description: Solar street light during the day under the control of the intelligent controller, solar panels after exposure to sunlight, absorbing solar light and convert it into electrical energy during the day to charge the battery pack solar module, battery pack to provide power at night LED light source power supply to achieve illumination. DC controller to ensure batteries do not overcharge or over discharge and was damaged, along with light control, time control, temperature compensation and lightning protection, reverse polarity protection. Product parameters Body material: steel poles for the whole, the overall hot-dip galvanizing / spray system operating voltage: DC 12V-24V Controller: solar lighting dedicated controller, light control + time control, intelligent control (dark light from open, day lighting self-extinguishing) Solar Panel: crystal silicon 15-80WP (load profile) energy storage battery: fully enclosed maintenance-free gel batteries 12V17Ah-80Ah (depending on the load configuration) light source types: energy-saving high-power integrated LED, rare earths Energy efficient lamps (according to customer requirements) Protection: IP67 Operating temperature: -30 degrees to 70 degrees, wind power ≥150Km / h Lighting time: 4 to 14 hours (can be adjusted as needed) Pole height: 4 m ~ 12 m (according to customer requirements) Rainy day guarantee: continuous work 5 to 7 rainy days (regional / seasonal variations are different) (according to customer requirements) solar lights use solar lights do not need to lay underground cables, without paying lighting electricity, mainly used in urban roads, lighting and lighting of new rural roads construction, residential square, industrial parks, tourist attractions, parks and green belts and other places. Pre-sale, sale and all the products we produce solar lights are strictly enforced in accordance with standard materials testing, strict production process control, finished product shipment inspection to ensure that customers spend with the products, the company built a set of comprehensive pre-sale , service system, all for the benefit of customers, providing customers with peace of mind. We are committed to using the products if there is a problem, the city, we will rush day troubleshooting, if it is in the field, we will arrive in two days, to help customers solve the problem.
