Photovoltaic panel long medium pressure block installation tutorial

How to plan a PV installation?

Surface Area: The surface area of the site at which the PV installation is intended should be known, to have an estimation of the size and number of panels required to generate the required power output for the load. This also helps to plan the installation of inverter, converts, and battery banks.

What happens if a PV module reaches 30 volts?

Any contact of 30 V or larger DC Voltage can be fatal. In case of no connected load or external circuits, modules can still produce voltage. Please use insulation tools and wear rubber gloves when operating modules in the sunlight. No switch is on the PV modules.

How to install PV modules in hot and humid environment?

PV modules install under hot and humid weather condition. PV modules installation site is under long-term humid environment such as water floating application. To reduce the risk of PID, on the modules DC connection site, it is recommended to connect the negative to ground.

What if a Longi PV module is broken?

To inform the LONGi customer service personnel within two weeks when modules are found broken or other significant abnormality. Refer to the《LONGi PV Module Operation and Maintenance Manual》for details on module maintenance.

Can a PV module be switched off?

PV modules produce electricity when exposed to daylight and individual modules cannot be switched off. Hence, unlike most other electrical installation work, the electrical installation of a PV system typically involves working on a live system. See requirements of Regulation 14 of Electricity at Work Regulations 1989.

What is tilt angle of PV module?

Tilt angle of PV modules refer to the included angle between module surface and horizontal ground. The module will obtain the maximum power output when directly facing the sunlight. Modules are preferred to be south-facing in the north hemisphere and north-facing in the south hemisphere.
