1, first check the controller battery indicator light is bright, if not bright check whether the connection line of the controller and battery is off, if the connection line is normal, use the multimeter to detect the battery voltage, the battery voltage is normal, the replacement of the controller.
2, check whether the controller load indicator is lit, and use multimeter to check the output voltage to see if there is voltage output. If there is no voltage output, change the controller.
3. Do PV modules need to face south?
It is the best to take the PV module south. In order to ensure that the component can receive as much as possible light radiation as possible, we have designed the optimum slope design in accordance with the regional sunshine conditions when designing the component support.
4. Is the solar panel fragile?
Solar panels are made of fairly strong tempered glass panels, which are tested by hail.
5, how much energy can a solar street lamp produce?
Different configurations have different power and lighting duration. We will recommend or design street lamps according to your lighting requirements and local conditions.
6. What if the solar panels are shaded?
Solar panels should be installed in the sun without shades. Even a small amount of shading will greatly reduce the power output of the system. In the initial location of the installation of solar street lamps, shelter should be avoided.
7. Do you want to clean solar panels regularly?
Usually, there is no need to clean the solar panels regularly. In most areas, there is enough rainfall to clean the panels. If it is in a dusty area, timely cleaning is necessary. Use hose to rinse and clean. Do not tread or walk on the solar panel when cleaning, do not use metal, hard material scrubbing or grinding methods to clean, do not spray water at high temperature cleaning.
