Techno-economic model of nonincentivized self consumption with residential PV systems in the context of Dominican Republic: A case study
2022
Garabitos Lara, Edwin
The progressive fall in the cost of residential photovoltaic (PV) systems opens the possibility of evaluating systems that do not export surpluses to the grid, avoiding bureaucratic procedures and effects on the grid. The main purpose of this papers is to present a techno-economic model based in the context of Dominican Republic, to evaluate the profitability of residential PV systems, considering a non-incentivized self-consumption scheme, a step tariff of electricity and monthly electricity consumption. The methodology consists of maximizing the net present value (NPV) through the number of PV panels; subsequently, the simple investment recovery time (SPBT), the internal rate of return (IRR), the self-sufficiency rate (SSR), the self-consumption rate (SCR) and others quantities are obtained. In addition, a methodology is proposed to determine the self-consumed energy based on daily power demand profiles, differentiating between regular and irregular loads. For a domestic house with an average monthly energy of 579 kWh, the optimal value of the NPV was 535 USD with a SPBT of 4.83 years and a IRR of 20.8%. The results indicate that non-incentivized self-consumption with PV systems can be profitable in the residential sector of Dominican Republic.
