การศึกษาความเป็นไปได้ของการติดตั้งโซลาเซลล์บนหลังคาบ้าน

Abstract

This project is a feasibility study of installing solar cells on the roof of a house. with the purpose of studying installation cost The rate of return on investment and payback period of 1.5-10 kW solar cells, both sold for electricity and used by themselves.

This operation consists of collecting general information about solar cell installation process, cost of materials for solar cell installation, calculating the installation investment cost. Solar cell calculates the rate of return Solar cell calculates the payback period for installation. Solar cells of each model Then use the information to analyze and make investment decisions.

The results of the study of installing solar cells on the roof of 1.5-10 kilowatts, found that it is worth investing in installing 10 kilowatts of solar cells to sell electricity to the electricity grid. The highest yield is 23.87% with a payback period of 6.03 years, while the rate of return for electricity itself is 14.07% with a payback period of 11.46 years.
