Solar Design Services positions itself as a PV design and permitting support partner for solar installers and businesses in the United States. Its core services include sales proposals, permit design, PE engineering review and stamping, PTO/Interconnection applications, and preparation of AHJ/Utility compliance documents. The website claims a 98% approval rate for permit designs and engineering stamps, standard solar design delivery within 24–48 hours, and sales proposals completed in 6–24 hours.
Its workflow is fairly comprehensive: it starts with a welcome call to clarify project requirements, followed by production checks, shading analysis, and an initial layout. After client confirmation, the project moves into permit design, producing a site plan, roof plan, BOM, electrical line diagrams, string layout, placards, and hardware specifications. Professional engineers then conduct structural and electrical reviews and provide stamps, after which the company assists with interconnection and permit applications. Its PTO service covers utility forms, net metering agreements, utility follow-up, and final PTO confirmation. The site also mentions experience with 100+ utilities and AHJ submissions across 40+ states and 300+ jurisdictions.
Pricing information is limited. The site does not disclose packages, per-project pricing, or subscription plans, and only emphasizes affordability and reduced operating costs. It is more like “outsourced PV engineering design plus online tools” than a standard SaaS product. As for third-party tools, the sales proposal service mentions using Helioscope, Aurora, and PVsyst for simulations, but it does not explain whether account-level integrations, APIs, or automated data synchronization are available. Enterprise software capabilities such as team permissions, a customer portal, APIs, and data security certifications are also not disclosed.
Its strengths are that the service chain covers key stages from sales to permitting, stamping, and interconnection, making it suitable for installers that want to outsource tedious design and documentation work. 24/7 support and fast turnaround are valuable for the pace of US projects, while white-label proposals can help sales teams maintain brand consistency. The drawbacks are the lack of transparent pricing, SLA details, payment methods, compliance and security information, and descriptions of software-like capabilities. Before enterprise procurement, buyers should verify delivery standards, responsibility boundaries, the number of revisions included, and data confidentiality terms.
It is better suited to installers, EPCs, and sales teams serving the US residential and commercial solar markets. It is not ideal for companies looking for pure software, self-hosted deployment, or an open API platform. Access from China cannot be determined from the site content. Since its target market, payments, and compliance are all US-oriented, Chinese teams considering it should pay attention to cross-border communication, USD payments, US AHJ/Utility compatibility, and alternatives such as Aurora Solar, Helioscope, PVsyst, or local PV design services.
