JAPANESE SOLAR STREET LIGHT 60W

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.

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.

Fully automatic booster solar water pump

The solar-specific hot water booster pump adopts an advanced digital control system and can automatically adjust the operating status according to parameters such as water temperature and water flow.The built-in temperature sensor monitors the water temperature in the solar collector, when the set threshold is reached, the water pump is activated to ensure rapid circulation of hot water.Meanwhile, the flow sensor detects the water flow, when the flow rate is lower than the preset value, it will automatically stop working to avoid unnecessary waste of energy.

The cost of solar panels

While the upfront costs of solar panels have dropped by over 70% in the past decade, a comprehensive lifecycle analysis includes several key components: initial purchase and installation ($15,000-$25,000 for an average home system), ongoing maintenance (roughly $300-500 annually), inverter replacement (typically needed once during the system’s lifetime), and eventual decommissioning costs.
