Solar PV System Design & Proposal Engine
Size PV arrays from consumption, model 25-year yield/degradation and generate a priced BoM + financed savings proposal
Solar PV System Design & Proposal Engine Solar installers usually hand-build proposals in spreadsheets: sizing the array from the customer's consumption, guessing at yield, and eyeballing payback. This app is a full sizing and financial engine:

Why Choose This Module
Sizing: required kWp from annual consumption + target offset %, panel count from module wattage, actual array kWp, roof-area fit check. Inverter sizing against a target DC/AC ratio. Yield: location irradiance (kWh/kWp/year) combined with project-specific derates (shading, orientation/tilt, temperature, soiling). 25-year production schedule with year-1 + steady-state panel degradation. Self-consumption vs. grid export split, with escalating import/export tariffs driving a year-by-year savings table. Cash or loan financing (amortized payment), simple + schedule-based payback, 25-year ROI and IRR. Auto-generated Bill of Materials from a panel/inverter/balance-of-system catalog, and a printable proposal report.
