Step 1: Electrical Design

Solar Panel

Panel brand

Panel series Panel model / wattage

Pmax (W) Voc (V) Vmp (V) Isc (A) Imp (A) Temp. coeff. Voc (%/°C) Temp. coeff. Pmax (%/°C) Length (m) Width (m) Weight (kg)

Total panel quantity

Total DC capacity: 0.00 kWp

Inverter

Inverter brand

Inverter series Inverter model

Rated AC (kW) Max DC input (kW) Phase No. of MPPTs Strings per MPPT Max DC voltage (V) MPPT min (V) MPPT max (V) Max current / MPPT (A) Max Isc / MPPT (A)

Number of identical inverters

Total AC capacity: 0.00 kW

Site & cable inputs

Min. ambient temp. (°C) Max. cell temp. (°C) Array to inverter (m, avg.) Inverter to ACDB / meter (m)

Electrical Design Results

Stringing (per inverter)

Single Line Diagram (SLD)

Conceptual panel layout (per inverter, colour = string)

Electrical Bill of Materials

Disclaimer: calculations are simplified and indicative. Cable sizes, protection ratings and earthing must be confirmed by detailed engineering, site survey and DISCOM / CEIG norms. Diagrams are conceptual.

Step 2: Structural Design

Structure parameters

Roof / mounting type

Panel orientation Panels deep per table

Tilt angle (°) Front clearance (ft) Site latitude (°N) Row-to-row gap (ft, blank = auto)

Section profile

Panel layout (rows facing South)

Structural Design Results

Side view (typical table)

Structural Bill of Materials

All weights are estimates for GI sections. Final member sizes, foundation and anchoring must be validated by a structural engineer for site wind speed (IS 875 Part 3) and roof condition.

Common Answers: Design Tools, Compatibility & Engineering Guide

India Specific Solar Design Knowledge Base

Is there a free tool to calculate solar string sizing?

Yes. Use the Kamaxi Electricals Design App to auto-calculate exact string lengths for Hitachi or Hopewind inverters.

How to generate a Solar SLD online?

You don't need AutoCAD. Our Kamaxi Electricals Design App features an automated SLD generator that instantly draws a compliant diagram.

Check inverter compatibility with 600Wp+ TopCON modules?

High-current modules can trip inverters. Use the App to verify if Adani Solar high-wattage panels fit your inverter's MPPT limits.
