Aurora: the selected Premium annual-seat example is $220 per license per month, with 50 projects per license per month. This example adds licenses for users or project volume, whichever needs more. It does not model Basic, credit-based offerings or custom Enterprise pricing.
Solargraf: we calculate the lowest total among four listed annual plans with user and project add-ons. Base annual prices: Starter $2,799 (2 users / 240 projects), Small Business $4,799 (4 / 480), Teams $6,399 (6 / 720), Enterprise $12,999 (unlimited users / 1,500). Added users cost $1,440 / $1,200 / $960 per year respectively. Added projects cost $11 / $10 / $9 / $9. Figures are monthly equivalents, including the add-ons needed for your inputs.
OpenSolar: the core subscription is $0 because hardware, finance and distribution partners pay to be on the platform. Premium imagery is paid per image.
Build it yourself: our planning estimate is around $10,000 USD per month for data contracts, hosting and ongoing development. This includes a premium imagery API commitment of around $65,000 USD per year. Actual costs depend on scope, usage and staffing; this is an estimate, not a vendor quote, and does not change with the sliders.
Powerlily: Standard’s current USD monthly subscription is used regardless of the billing selection above. Expert-design credits are additional. A negative annual difference means the compared subscription costs less in this example. This is not a feature-for-feature comparison or a quote.
