Organized Projects
During the welcome call for One Place Solar, we walk you through the business presentation to help you understand the workflow and how to initiate projects. This comprehensive approach ensures that you are well-informed and prepared to start your journey with us.
In the Solar Contractor Onboard process, the agreement signing between the company and the contractor marks a crucial step. Once the pricing is set, the contractor can then start sending projects. This structured approach ensures clarity and transparency in the working relationship between both parties, setting the stage for successful and efficient project execution.
In the preliminary design process, conducting a production check and shade analysis is crucial. This ensures the best layout is created based on optimal irradiance levels. Once the layout is finalized, it is sent back to the contractor for approval. This step ensures that the design meets all necessary requirements and is ready for implementation.
Once the preliminary design is approved, the next step is to begin the permit designing process. This involves creating essential documents such as the site plan, electrical diagram, Bill of Materials (BOM), and equipment specifications. Once these are ready, they are sent back to the contractor for approval before moving forward with the stamping process. This process ensures that all necessary details are in place and align with the project requirements.
Once the permit design is approved, our in-house professional engineers conduct thorough structural and electrical reviews. Upon completion, the permit plan is stamped and signed, signaling its readiness for submission to utility companies and the AHJ. This meticulous process ensures compliance with regulations and standards before proceeding further with the project.
After obtaining the permit plan stamp, we assist in submitting the interconnection and permitting application to the utility and AHJ. By ensuring that the plans are thoroughly organized and comply with regulations, we aim to facilitate the approval process efficiently.
