Design Capabilities
Both Solargraf and SurgePV offer cloud-based solar design, but they serve different audiences and have different levels of hardware flexibility.
Solargraf Design Strengths
Solargraf provides a streamlined residential design experience built around the Enphase product line. The platform features AI-powered roofline detection that automatically traces roof edges from aerial imagery, along with NREL shading data for accurate shade analysis in the US.
The core strength is deep Enphase integration. When you select Enphase microinverters and batteries, Solargraf auto-configures the system, validates compatibility, and generates Enphase-specific technical documentation. For teams that exclusively install Enphase equipment, this tight integration removes friction.
The downsides are tied to that same tight integration. Solargraf is optimized for Enphase hardware, which limits flexibility if you work with multiple inverter brands or want to offer clients competitive bids across manufacturers. The platform is also primarily designed for residential projects in the US and Canada, with limited commercial capabilities and minimal international support.
SurgePV Design Strengths
SurgePV is hardware-independent and works with all major module, inverter, and battery manufacturers. This gives teams the flexibility to spec the best equipment for each project without being locked into a single vendor ecosystem.
The platform includes AI-powered auto-design, 8760-hour shade simulation, and native support for residential, commercial (up to 5MW), and utility-scale projects. SurgePV also generates SLDs, three-line diagrams, wire sizing, BOM, and permit packages natively — covering the full engineering workflow without additional software.
For teams that want to grow beyond residential Enphase-only installations, SurgePV provides a platform that scales with the business.
Proposal & Sales
Solargraf Proposals
Solargraf produces polished consumer-facing proposals with strong US market features. The platform integrates with 30+ financing providers including Sunlight Financial, Mosaic, and GoodLeap, making it straightforward to offer financing options directly within proposals.
Built-in e-signature capability allows homeowners to sign contracts digitally, and the CRM-like project tracking helps manage the sales pipeline. For US residential teams selling Enphase systems, Solargraf creates a smooth design-to-sale workflow.
The limitations are geographic. Financing integrations are US-centric, and the financial modeling does not support international tax structures, multi-currency calculations, or global incentive programs.
SurgePV Proposals
SurgePV generates both web-based and PDF proposals with flexible financial modeling. The platform supports cash, loan, lease, and PPA structures with multi-currency support and global tax/incentive modeling.
While SurgePV does not yet match Solargraf’s depth of US financing provider integrations, it offers broader geographic coverage and more versatile financial modeling. The proposal builder includes energy yield at P50/P75/P90 confidence levels, ROI calculations, and custom branding — all hardware-independent.
Pricing Comparison
One of the biggest differences between Solargraf and SurgePV is pricing transparency. Solargraf does not publicly disclose pricing, while this solar design software lists prices on its website.
| Plan | Solargraf | SurgePV |
|---|---|---|
| Entry Level | Not publicly disclosed | $1,499/year (3 users) |
| Premium | Not publicly disclosed | $1,299/user/year (5 users) |
| Enterprise | Custom | Custom |
| Pricing Transparency | Opaque — requires sales call | Published on website |
| Hardware Lock-in | Enphase-centric | Hardware-independent |
