How the Marssy Energy marketplace works
Marssy Energy connects property owners with accredited EPC partners through a stateless, request-time data flow. This page documents each stage, the data exchanged, and typical timelines.
Summary
Homeowners complete the Smart Energy Simulator (about 2 minutes), Marssy Energy matches them to accredited installers by region and vertical, installers submit proposals on-platform, and the homeowner chooses a partner — with no Marssy Energy commission on the contract.
Process flow
- 1~2 min
Smart Energy Simulator
Capture property, consumption, and technology preferences to produce directional production, savings, and CO₂ estimates.
- Inputs: address/region, roof or site area, orientation, monthly bill or kWh, selected verticals (solar, battery, EV, heat).
- Outputs: estimated system size (kW), annual production (kWh), savings range, payback band, CO₂ reduction.
- Data is processed in-memory for the session; no persistent storage of raw utility bills without consent.
- 2Usually < 24 h
EPC matching
Qualified projects are routed to accredited partners whose coverage, verticals, and capacity align with the request.
- Match keys: geography (country/region), vertical certification, project size band, language.
- Installers receive a structured lead card with simulator outputs — not raw PII until the homeowner opts in.
- Homeowners are never charged a marketplace fee; installers pay flat SaaS subscription only.
- 33–14 days typical
Proposal comparison
Review scope, equipment, warranty, and price from multiple EPCs in a consistent format.
- Standard fields: module/inverter brands, kW DC/AC, warranty years, gross price, financing notes.
- Optional site visit refines design; engineering drawings precede contract signature.
- Marssy Energy does not rank installers by paid placement — subscription tiers affect features, not lead auction priority.
- 4Project-dependent
Installation & handover
Contract and delivery occur directly between homeowner and chosen EPC; Marssy Energy may surface milestone tracking where enabled.
- Permitting, interconnection, and commissioning follow local regulations (MCS, NABCEP, national electrical codes).
- Post-go-live: optional performance monitoring integrations (roadmap).
- Disputes are handled between parties; Marssy Energy provides platform support, not installation warranty.
Roles & responsibilities
Homeowner or business: provides accurate site data, compares proposals, signs contract with chosen EPC.
EPC partner: accreditation, site survey, design, permitting, installation, warranty to customer.
Marssy Energy: simulator, matching infrastructure, subscription billing for installers, platform support.
Data handling principles
Simulator calculations run on aggregated benchmarks (irradiance, tariff bands) refined at quote stage by the EPC.
Personally identifiable information is shared with installers only after the homeowner requests contact or quotes.
