# ☀️ REModel — Renewable Energy Financial Modeling Platform
|
||
> Python calculation engine + FastAPI backend + Next.js frontend for **Indian renewable-energy** (solar) financial modeling. *This is the software embodiment of the day job.*
|
||
|
||
## Purpose
|
||
Turn the manual, spreadsheet-bound work of **utility-scale solar project finance** into a structured platform — site/technical inputs → energy yield → financial model (debt sizing, returns).
|
||
|
||
## Why it matters
|
||
Directly fuses Manohar's two strongest domains: [[Renewables Overview|renewables engineering]] and [[Finance Overview|project finance]]. The professional version of what he does at [[Renewables Overview|ReNew]].
|
||
|
||
## Architecture
|
||
- **Calc engine (Python):** the modeling core (links conceptually to [[8760 Energy Simulation]])
|
||
- **API (FastAPI):** serves model runs
|
||
- **Frontend (Next.js):** inputs + visual outputs
|
||
- Docs present: `PROJECT.md`, `PRD.md`, `CODEBASE_INVESTIGATION.md`, `RE_Financial_Modeling_Platform PRD.md`
|
||
|
||
## Status & history
|
||
53 commits over a focused **May 2026** sprint.
|
||
|
||
## Open questions / next
|
||
- [ ] Is REModel intended as a product, an internal tool, or a portfolio piece?
|
||
- [ ] Relationship to the [[8760 Energy Simulation]] platform — same codebase or successor?
|
||
|
||
## Lessons / related
|
||

## Modeling detail (from build sessions)
|
||
- **Tech basis:** an 8760 hourly profile (e.g. **Rajasthan**), CUF prorated (e.g. 21% → 19.28%), extended to **25-year** generation (leap-year Feb 29 reuses Feb 28 profile)
|
||
- **Capex → funding waterfall:** component-wise capex, funded by a **debt + equity mix**, progressing in **phases**
|
||
- **Solar & wind** scenarios with configurable defaults
|
||
- **Land costs:** upfront **Land Lease (5-yr)** on a **per-acre** basis; acreage from DC capacity (~**2.5 × Solar DC** for fixed module, higher for tracker/wind)
|
||
- **Inputs sheet** drives the model (e.g. Solar DC MWdc capacity) → outputs capex/funding/returns tables
|
||
- UI built with an **"agentation" visual-feedback** workflow during iteration
|
||

The energy core is the [[8760 Energy Simulation Model]] (see the knowledge note).
