Engg. & Design

EcoSoch’s Engineering and Design vertical was formed to address the overwhelming need for our expertise in the rooftop-scale design space. This vertical embodies the pinnacle of quality and experience in the PV industry led by a group of PV experts focused to deliver world-class service to our design clients. Our clients receive unparalleled quality and insight that comes from years of evaluating equipment and evolving with the industry. Contact us to determine how we can help you on your next project either by email info@ecosoch.com or through phone 81234 10101.

We offer custom turnkey design and engineering services of the highest standards. Whether it is a simple one-page CAD drawing of a site, or a multiple view with single line diagrams, we are here to enable you to move forward through the sales process with confidence. We will help you make the site-specific decisions regarding your mounting, wiring, module and inverter matching, monitoring and overall system size. Whatever your needs may be, we can add value to your project and help you make more informed decisions after all factors are taken into consideration.

EcoSoch takes pride in using the latest solar PV system design that allows our clients to receive the most effective energy service solutions. The company has well educated and skilled labor force that understands the procedures involved in creating outstanding solar energy plants for high electrical output.

A carefully constructed and complete design is the foundation for a successful PV system. A well-established plan helps to ensure that our installation team would be able to proceed efficiently with system construction. Hence, the details of your system must be carefully established and clearly outlined for a smooth installation process.

Our design services are not limited to only the electrical components. We also have structural engineers and fabricators to design the physical infrastructure that literally supports the system. This integrated approach to the design process allows us to provide you with a comprehensive set of plans and specifications, the quality of which is one of the best in the industry.

We deliver complete construction-ready plan-sets within budget and on-time – no exceptions. Our interest is in delivering the best system to you, our client, with your highest interests considered at every step of the design process. We believe quality during the design process is the first step in assuring you will not be performing costly retrofits or replacement of equipment either before or after your system is completed. Your investment on our Design & Engineering services will be recouped many-fold through fewer problems during construction and for the life of the system.

Quality Control Process

EcoSoch incorporates a quality control process that is class-leading by utilizing our O&M team called SolarCare to review each and every design prior to each milestone delivery. This means that your plans are looked at by another PV expert that is not part of the design team for construct-ability, safety, code compliance, and overall presentation. The depth and level of expertise reviewing each set of plans we produce are second-to-none in the industry. You can rest assured knowing the best and brightest engineers and technicians are looking at every part of your system before it is built. EcoSoch Engineering also offers third-party reviews of engineered designs by EPC’s and other design firms using the same staff that performs our internal engineering quality reviews.

Our participation in your project elevates quality from the start, which saves both time and money. Coupled with our inspection and commissioning services a full quality assurance package can be implemented, and your project will produce the amount of power you expect.

Services provided by Engg. & Design team are listed below:

  • Technical Site Visit

    • Team performs detailed survey of rooftops for suitability and assess the capacity that can be installed.
    • Detailed site survey report would be submitted
    • The report would include the Cable routing, Location of earthing pit, Lightning arrestor, Inverters, Meters, BoS components, Termination point, etc.


  • Layout Preparation

    • Layout is prepared in SketchUp and the 3D drawings would be shared with all stakeholders


  • Shadow Analysis

    • Shadow analysis is performed using a specialised tool called Solar Pathfinder at site.
    • Inputs from Solar Pathfinder are used for assessing the expected energy generation at site
    • Shadow analysis is also done in SketchUp and the animated analysis is shared with all stakeholders
    • We also use Helioscope for shadow analysis and Irradiance map.


    The below video was prepared using SketchUp and shows the shadow formation on Dec 21st when the sun is at its lowest position and casts the longest shadow:


  • Wind Load Analysis

    • Wind load analysis is done in STAAD Pro particularly for elevated structures
    • The detailed STAAD pro report is used for assessing if the structure would be able to handle high wind loads (approx. 150km/h)


  • Preparation of AutoCAD Drawings

    • Module Layout
    • String Layout
    • Conduit cable routing
    • Trench details and routing
    • Single Line Diagram
    • Equipment Layout
    • Earthing Layout
    • Earthing strip and Earthing pit details
    • Lightning Arrestor Layout
    • Communication Layout
    • Mounting Structure Details

    and much more…

  • Detailed Project Report (DPR) Preparation

    The purpose of DPR is to answer the following questions:

    • How will the design be done?
    • What is the criteria for selecting the components and technology?
    • How will the installation be done?

    In addition to providing exhaustive details relating to all aspects of a project, the DPR also serves as an instrument for improving customer awareness.


    Highlighted below are the subjects that would be covered in the DPR:

    • Shading Analysis
    • Energy Generation Analysis using SAM
    • Sensitivity Analysis (P50 & P90)
    • Financial Analysis
  • Financial Analysis Reports Preparation

    For preparing the Financial Analysis report, the solar rooftop project would be considered as a separate entity/company generating revenue by means of savings in electricity bills. Thereby, the report would include detailed calculations and statements as mentioned below:

    • Profit & Loss statements (P&L)
    • Cash Flows
    • Balance Sheet (with Assets & Liabilities)
    • IRR
    • Depreciation
    • Debt Service Coverage Ratio (DSCR)
    • LCOE

    This would enable the decision makers (Developers and Financiers) to assess the financial viability of the project.


  • Lightning Protection System Design

    Lightning Protection System (LPS) design as per IEC 62305-3 is an important aspect for any rooftop solar plant

    Scope would include:

    • Risk assessment of the project using best-in-class software
    • Arriving at the protection class
    • Recommend the appropriate Lightning Arrestor (Conventional or Early Streamer Emission – ESE type)
    • Recommend the separation distance to be maintained for the down conductor and air terminals


  • Earthing Design

    Earthing design encompasses the following:

    • No. of DC and AC Earthing pits required for the project based on fault current
    • Earth strip material to be used and its cross-sectional area
    • Earth rod design (length, cross-sectional area, micron level of the Cu bonding, etc.)
    • Earth pit design (depth of the pit, distance between pits, backfill compound, distance from building, etc.)


  • Consultation on Mounting Structure Design (Penetrable & Non-penetrable)

    Consultation would be provided on the type of Module Mounting Structure to use for different types of roof like Flat, Sloped RCC or sheet roof, Elevated structures, etc.

    Some clients are particular about not penetrating their roofs and need non-penetrable solutions. For such clients, customised non-penetrating solutions would be designed (as shown below)

    Consultation could be provided even before the building is erected on the type of roof suitable for solar installation.
