Vietnamese EPC firms producing rooftop proposals for factories. Solar distributors offering design tools to installer networks. Developers standardising single line diagrams across many sites.

Free software removes licence cost for installers. Automated design and bill of materials shorten quoting time. Integrated finance and e-signature support closing deals in one tool. An API and permitting integrations connect the platform to existing workflows.

Rooftop solar installers worldwide are digitising design and sales to quote faster. Vietnamese and Southeast Asian EPC firms serving factories and commercial rooftops face the same pressure to produce fast, bankable proposals.
