6 FAQs about [Requirements for photovoltaic panel assembly strings]

What is the minimum solar PV string size?

Rounding up, the minimum string size is 7 panels. Understanding the intricacies of solar PV strings, including how to calculate the number of panels per string and the importance of startup and maximum DC voltage range, is essential for optimising your solar power system.

What is the minimum wire size for a solar PV system?

JA Solar recommends installers use only sunlight resistant cables qualified for direct current (DC) wiring in PV systems. The minimum wire size should be 4mm2. Rating Required Minimum Field Wiring Cables should be fixed to the mounting structure in such a way that mechanical damage of the cable and/or the modules is avoided.

What is a solar PV string?

A solar PV string is a series of solar panels connected in a sequence to form a circuit. The panels in a string are connected by their positive and negative terminals, creating a single path for the electric current. The number of panels you can have on a string depends on several factors, including:

What is a solar panel string?

The “solar panel string” is the most basic and important concept in solar panel wiring. This is simply several PV modules wired in series or parallel. Solar panels feature positive and negative terminals. Wiring solar panels in series means wiring the positive terminal of a module to the negative of the following, and so on for the whole string.

How do I calculate the minimum solar panels per string?

According to the Solar Design Guide, to calculate the minimum panels per string: Determine the startup voltage of your inverter. 2. Divide the startup voltage by the panel voltage. 3. Round up to ensure you have enough voltage to meet the inverter’s requirements.

What are the requirements for a PV installation?

Virtually all domestic PV installations will fall under the scope of Part P. Part P requires the relevant Building Control department to be notified and approve the work. There are two routes to comply with the requirements of Part P: Notify the relevant Building Control department before starting the work.
