How to maintain a photovoltaic system?

Warning: Any electrical maintenance must shut down the PV system firstly. Improper system maintenance may cause fatal dangers such as electric shock and burning. Dust accumulation on the glass surface of the module will reduce its power output and may cause hot spots. So the surface of photovoltaic modules should be kept clean.

What is a photovoltaic solar module?

Risen’s photovoltaic solar module is a DC power supply, which has the character of high reliability and nearly no-maintenance. It can be used in power systems of remote areas, home power systems, renewable energy vehicles, hydropower stations, water pumps, communication system or constitute solar photovoltaic power station directly.

Should a general contractor install a solar PV system?

A general contractor may face a choice between using an electrical subcontractor or a solar subcontractor to install the PV system. A good solar contractor will have the expertise in solar PV systems plus qualified electricians on staff.

Do I need to meter a photovoltaic system?

It is assumed that aluminum framed photovoltaic (PV) panels mounted on a “post” and rail mounting system, the most common in the industry today, will be installed by the homeowner. While metering the system is encouraged, the specification does not address system wiring elements for associated system sensors or monitoring equipment.

What types of mounting systems can be used for PV power plants?

There are several different types of mounting systems that can be used for PV power plants, such as fixed-tilt support structures, single- or double-axis tracking structures, marine-grade support structures that prevent corrosion, and so forth.

How does a solar photovoltaic module bypass a diode?

When the solar photovoltaic module is connected in parallel with the bypass diode, the current in the system will flow directly through the diode, so as to bypass the blocked part of the solar photovoltaic module and minimize the heating degree and power consumption of the solar photovoltaic module. Each module has three diodes.
