Economic Feasibility of Solar PV System for Buildings
Abstract
A system design optimization and economic feasibility of a solar PV system for self-consumption is studied using long-term system performance simulation. The electric heater is used to replace part of battery storage to reduce the cost. Three parameters, RpL, Rhb , tbp , are derived to correlate the long-term system performance. It is found that there is an optimal design and the solar PV system is economical if it was used to replace partial demand which is paid at higher grid electricity price. This is the partial grid-parity.
