Our group project economical analysis in PV technology was divided in two main parts.

• "Family house plant" with 3.5 kWp
• "Commercial building" with 50 kWp

Family house Plant

The economical analysis is based on existing Projects with integrated PV panels In table 1, is shown the economical analysis taken for Photovoltaic panels with efficiencies varying from 10% to 15%.

Commercial Building

In table 2, is shown the economical analysis taken for Photovoltaic panels with efficiencies varying from 10% to 15%.
