Design of zero energy consumption home system in Bangkok for energy efficient plan 2015

Abstract

This paper focuses on the design of zero energy consumption for small building system that can support the government energy efficiency plan (EEP 2015). The design suits for small residential home in Bangkok that the energy consumption is up to 1,500 Wh/day. This paper designs the off-grid photovoltaic (PV) system which its structure consists of 3 main parts: generation, storage, and load. Experimental results can be the realtime observed via a web server. The appropriate proportion of PV energy : load energy : battery energy becomes 7:5:2 using the most PV energy collection scenario. The storage and generation ratio is 1/3.5, is tested for 38 days and sustained to serve during the ending of raining season in Thailand.
