    Benchmarking of Solar PV performance ratio among different regions in Peru: sample of five small-scale systems
    (LACCEI Inc., 2020-07) Camarena-Gamarra, Caroline; Calle-Maravi, Jose; Nahui-Ortiz, Johnny
    Five 3.25-kWp Photovoltaic Systems were installed in different regions in Peru. Solar irradiance and power output were measured during the entire year of 2019. On the basis of data registered, solar PV performance ratio was assessed for all systems. Analysis of how a variation of the solar irradiation and the power output may affect LCOE values was carried out. Implications for end users in terms of expected payback time due to different LCOE values were also assessed. It is concluded that Performance ratio changes over the year depending on which of the five regions the PV system was installed. Considering average monthly values, calculated for over a year, the highest value corresponds to Site Number 3 (Piura) while the lowest value corresponds to Site Number 2 (Lima UNALM). If LCOE from site Number 3 is considered as a basis for comparison purposes, then LCOE from site Number 2 would be 78.5% more expensive in terms of US$/kWh. Also, if payback time from site Number 3 is considered as a basis for comparison purposes, then payback time from site Number 2 would be 78.5% longer. Therefore, expected performance of a solar PV system, among different regions of the country, is a factor that should be taken into account when proposing policies and incentives for net metering squemes under distributed generation.

    Assessment of Cost-Benefit for a Net Metering Scheme based on Solar PV: Case Study on a University Campus located in Lima-Peru.
    (LACCEI Inc., 2020-07) Camarena-Gamarra, Caroline; Calle-Maravi, Jose; Nahui-Ortiz, Johnny
    A net metering scheme based on a 3.25-kWp Photovoltaic System was setup within the facilities of a university campus located in Lima-Peru for evaluation purposes. Solar PV system output as well as energy demand were registered for the entire year 2019. The contribution of solar PV production to total electricity demand is analyzed, considering seasonal variations in both the PV production and the energy consumption within the period of one year. Total implementation cost was calculated by adding CAPEX and OPEX values for a 3.25-kWp solar PV system operating under local conditions. In this case, total investment cost for the PV systems is estimated as 4,063 US$ while annual O&M costs are estimated as 71 US$. Considering a local electricity tariff of 0.15 US$/kWh for the end user, annual cost savings is 1068 US/yr and the overall simple payback turns out to be 4.3 years. Therefore, it can be expected that potential introduction of a net metering squeme may become attractive for end users under local market conditions.
