Photovoltaic System Sizing & Life-Cycle Cost

A MATLAB-based sizing study for a passive residential building in a Mediterranean climate, combining hourly seasonal demand, solar generation, grid exchange, system size, and long-horizon economic analysis.

Sizing generation against real demand

The study examined optimal PV sizing for a passive residential building in a Mediterranean climate. The model combines solar resource, seasonal hourly load profiles, photovoltaic output, grid purchases and exports, and the economics of different system sizes.

PV sizing model

The surviving MATLAB implementation evaluates up to 50 panel-count choices, applies inverter efficiency and panel characteristics, and computes energy bought from and sold to the grid over the modeled demand profile.

Life-cycle economic comparison

The economic model combines system cost, operating and maintenance factors, salvage value, inflation, interest, and a 30-year horizon. The objective is not simply to maximize annual generation, but to compare the long-term economic consequences of different PV sizes against the building's demand and grid interaction.
