Solar PV. Solar Generation Side. Strings & Tables.
Inside a PV field the panels are fist connected in
SERIES: POSITIVE to NEGATIVE
This SUMS the VOLTAGES of all the panels connected this way.
WARNING: NEVER EXCEED THE WHOLE SYSTEMS VOLTAGE RATING PER STRING. USUALLY 1,000 V.(*). YOUR PANELS CAN CATCH FIRE !
In the past, for single user isolated systems based on rudimentary charge controllers and lead-acid batteries, with specially manufactured panels, after a short series connection a PARALLEL connection was done:
PARALLEL: POSITIVE to POSITIVE AND NEGATIVE TO NEGATIVE
This SUMS the AMPERES of all the panels or STRINGS connected this way.
WARNING: NEVER EXCEED THE CHARGER AMPERAGE RATING. YOUR CABLES WILL CATCH FIRE !
(*) There are systems designed for 1,500 V, but the whole system has to be designed for that level, panels, cables, protections and inverters. There are only 8 panel manufacturers who offer 1,500 V panels, but little stock available.
Solar PV. Solar Generation Side. Strings & Tables.
Strings are organized in “tables” and tables into “arrays”.
Cables between panels shall never jump between tables.
There are many possible configurations of tables, according to how many panels are in vertical order, normally it varies between 1 and 4.
The panels can be oriented either in vertical position or horizontal position, as by where their long side is oriented.
Here are some examples of tables:
Strings must follow the table
Strings can be routed on the table to reduce cable to reach the combiner of inverter.
Multiple strings can be routed on the table in different shapes to reduce cable to reach the combiner of inverter.

Voltage Drop Calculation and formula for Three Phase system.
For 3 Phase 3 Wire system.VD = 0.866 × I × RVD = 0.866 × I × 2 × L× R/ 1000
For 3 Phase 4 Wire systems.VD = 0.5 × I × RVD = 0.5 × I × 2 × L× R/ 1000 Where,
VD = Voltage Drop in Volts.I = Wire Current in Amperes.R = Wire Resistance in Ohms (Ω) [Ω/km].L = wire distance in meters.

Panel installation is a critical and delicate process.
Teams of 2 to 4 people are needed.
On 3rd and 4th panel part of the team will have to stand in a small scaffolding structure.
The lower panel always goes first and has to be perfectly fitted and aligned.
The bolting is done ONLY with power tools with torque settable drivers. The panel manufacturer will provide the right number of Nm torque.
Any broken panel must be put aside to avoid stumbling on it and injuries.
