20W SOLAR STREET LIGHT FACTORIES

Solar light sensing system

The system is based on the combination of two approaches to precisely track the sunlight: first, using multiple LDRs (light-dependent resistors) as photo sensors to track the position of the sun by balancing the resistivity using a proportional integral deprival (PID) controller, and the second approach using the time-based control for cloudy days when sunlight is diffused, getting the time GPS coordinates and time to calculate the accurate position of the sun by determining the azimuth and altitude angle.

Sri Lanka Street Solar Panel solar Power Generation

The Ministry of Power and State Minister of Solar, Wind and Hydro Power Generation Projects Development has launched a community based power generation project titled 'Soorya Bala Sangramaya' (Battle for Solar Energy) in collaboration with Sri Lanka Sustainable Energy Authority (SLSEA), Ceylon Electricity Board (CEB) and Lanka Electricity Company (Private) Limited (LECO) to promote the setting up of small solar power plants on the rooftops of households, religious places, hotels, commercial establishments and industries.

German solar street lighting system

Environmentally friendly lighting using solar power - in winter, when there is little sun, the light automatically switches to mains grid power.For illuminating streets, yards, driveways, deliveries, access roads, waste collection points, car parks, building yards, recycling centres.Mounted on a round metal pole or with a wall bracket at an extra charge.All-In-Two luminaires represent a good compromise between compact design for normal lighting poles and reliability.The solar module can be rotated separately from the luminaire in the direction of the sun.The brightness is comparable to a 125W mercury vapour lamp or 70W sodium vapour lamp.In winter, we recommend switching down the intensity of the basic lighting to ensure sufficient recharging even at dark weather.

Solar Energy Storage Cabinet System Introduction

This article will introduce in detail how to design an energy storage cabinet device, and focus on how to integrate key components such as PCS (power conversion system), EMS (energy management system), lithium battery, BMS (battery management system), STS (static transfer switch), PCC (electrical connection control) and MPPT (maximum power point tracking) to ensure efficient, safe and reliable operation of the system.
