Our initial site assessment process considers the suitability and cost effectiveness of the project, addressing both on-site characteristics as well as utility interconnection potential, the likelihood of project approval, the degree of project difficulty, the cost of potential upgrades, and evaluating the project time-frame. We can also assist project developers in identifying and qualifying project sites and opportunities while providing fatal-flaw analysis.
We have extensive experience in designing of residential solar system. We provide variety of services in this sector ranging from sales to interconnection. Our team has in depth knowledge of AHJ and Utility requirements and are acquainted with various codes and compliances.Proposal Drawings
We provide accurate proposal documents for solar installers helping them to gain business. We provide 12-24 hours turnaround to the 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 national electric codes (NEC) and local municipality standards. We are proficient in Flush Roof Mount, Tilt Roof Mount, Non-Penetrating Roof Mount, Ground Mount, Micro-inverters etc...
We design and draft complete Solar Permit sets which includes:
We also understand the various AHJ (Authority having jurisdiction) and HOA (Home owners association) requirements / guidelines and has been working using varied static and dynamic blocks and templates.
We do shading analysis and solmetric calculations to ensure the proper positioning of the solar panels. We are conversant with the Solmetric PV Designer / Solmetric SunEye and with calculation applications like PVsyst.Design Changes/Revisions
Changes occur in the proposed solar system many a times. DIN Engineering Services can step in at any stage and can take the design forward. We can work on changing racking, electrical equipments, mounting planes etc... and can provide you 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 having the most recent drawings, we provide the as-built drawings services to our customers. We require either the hand sketch of the changes made during the installations or the photographs so that we can amend those in the drawings.
USA Solar Design, Engineering Services has experience in designing systems from 20kW up to several hundred kW in this sector. We provide detailed commercial design sets compatible to the codes. With our experience we can assist you in choosing the best equipment for Balance of system as it is based on a number of site specifics including wind/snow, and general climate characteristics that direct the pairing of inverter/module, roof/racking and specific incentive schemes to match the system size.
We have successfully designed several commercial projects 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.
We can provide following:Pre-Sales Support
We have expertise in providing you with the complete design packages for commercial installations.
Designing a PV power plant has unique opportunities, challenges and risks. As a installer/owner, it is wise to maximize the value of investment.
USA Solar Design, Engineering Services has immense experience and expertise to achieve a variety of complex design considerations and variables. We can assist you from site and equipment selection, to design considerations
We have worked on numerous utility scale solar projects (1mW to 120 mW). We have expertise in 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.
In the Design Phase we provide the following services:
We use the PVsyst version 6 PREMIUM - the most powerful software for photovoltaic systems, for the study, sizing, simulation and data analysis of complete PV systems. PVsyst tool helps in preliminary design, quick estimation of production for an early study of the installation, project design, detailed study, sizing and hourly simulation. We reply on PVsyst tool capabilities to calculate the PV system results which come in form of a full report, specific graphs and tables, and data export. The advanced functionality of the tool, management of the meteo and components databases and also includes specific pedagogic tools, and import of measured results for a close comparison to the simulation.
