Solar PV Design and Drafting

A solar energy system is a good choice if you have plenty of suns and have a properly designed system.  Building an effective, reliable and safe solar power system requires a number of key components.
The most important of these are careful design, good quality component equipment, and the correct installation procedures carried out by competent professionals. If these are done, then your off-grid or remote power system will last for long.

Designing a PV power plant has unique opportunities, challenges, and risks. As an installer/owner, it is wise to maximize the value of the investment.

In the Design Phase we provide the following services:


  • Electrical engineering design

  • Related structural engineering design

  • Soil erosion plan & Details

  • Fence Plan & Details

  • Phasing plan

  • Site plan for the proposed PV system

  • PV module structural mounting details

  • PV system block diagrams

  • Electrical connection details


We have extensive experience in designing the Residential Solar System. We provide a variety of services in this sector, ranging from sales to interconnection. Our team has in-depth knowledge of Utility requirements and is acquainted with various codes and compliances.

Proposal Drawings

We provide accurate proposal documents for solar installers, helping them to gain business. SOLARTECH-UK  provides less than a 12-hour turnaround to customers enabling them to pace up the signing up process. We just need the address of the locality, and we will create the proposal drawings by which the estimated system size can be determined.

Permit Drawings (On-Grid & Off-Grid)

We provide PV Permit and Installation design drawings for Residential PV Systems. Our designs meet the  NEC/IEC and local municipality standards. We are proficient in Flush Roof Mount, Tilt Roof Mount, Non-Penetrating Roof Mount, Ground Mount, Micro-inverters, etc.

Design Changes/Revisions

Changes occur in the proposed solar system many times. SOLARTECH-UK can step in at any stage and can take the design forward. We can work on changing racking, electrical equipment, mounting planes, etc., and can provide you a quick turnaround of as low as 12 hours.

As-built Drawings

The As-built Drawings show how the system was actually installed and reflect any changes made to the design during installation. If as-built drawings are not produced, the client will not have a record of how the system was actually installed.

To enable the client to have the most recent drawings, we provide the as-built drawings services to our customers. We require either hand sketch of the changes made during the installations or the photographs so that we can amend those in the drawings.


We have successfully designed several commercial projects (1MW to 5MW) with different types for racking systems on roof, carports, and ground mounts. We are equipped to prepare the PV array layouts, mounting details, BOS Elevations shading analysis, Electrical 3 line, and single line diagrams, etc.

  • Freestanding structures
    Extensive experience in designing the PV System on a free-standing structure like Carports, Single Axis tracking, Dual-axis tracking system, and Ground mount racking.

  • Rooftop

       We have worked on several rooftop commercial designs ranging from few kW to MW. We have designed this with                 various racking and module manufacturers. 

  • Ground Mount
    Designed Ground mounts for flat and sloping grounds using various racking systems. We can provide detailed arrangement drawings for ground-mount systems including the overviews from all directions.

Utility-Scale Designs

We have worked on numerous utility-scale solar projects (1MW to 120MW). We have expertise in a single axis, dual-axis, and fixed-tilt systems. We can provide all the E and L category drawings including 3 line diagrams, interconnection line diagram, construction details, and 3D sketch-up models for presentation purposes.

PVSYST Simulations

We use the PVsyst version 6 PREMIUM – the most powerful software for photovoltaïc systems, for the study, sizing, simulation and data analysis of complete PV systems.

Community Solar  Energy System Design Solutions

This design service is an innovative way for local matching of demand and supply in the form of integrated community energy systems. We design multiple approaches for supplying local communities with their energy requirement from high-efficiency cogeneration or tri-generation as well as from renewable energy technologies coupled with innovative energy storage solutions, renewable energies,  and energy efficiency demand-side measures.

  • Distributed Generation through renewable energies

  • ON-Grid (Micro plants with renewable energies connected to the grid)

  • OFF-Grid (Autonomous micro plants with renewable energies)
