Validation and application of Bristow Campbell model for estimating the global solar radiation in the Junin region

Abstract

In order to have a tool to estimate the monthly and annual solar radiation on the horizontal surface land in Junín region, no area in which this information is available, validated and applied adapted Bristow-Campbell model to estimate the monthly average global solar radiation. For the creation of the database of the study area was used documentary techniques proposed by Espinoza (2010) and it was necessary to gather as much information available magnitudes as maximum and minimum temperatures of the records made in the towns of Junín located within the study area. By applying the t Student test for related samples contrasted no differences between values measured and calculated with the Bristow-Campbell model of monthly average daily global radiation. It shows the values of the 19 weather stations that are in the Junín Region, with the highest global solar radiation Viques station Huancayo Province in the Sierra with 6.2 kWh/m2/day. Pichanaki Station of the province of Chanchamayo, which belongs to the Selva is the one with lower global solar radiation with 3.8 kWh/m2/day. Profitability is determined for the less profitable Selva and Sierra is very profitable. In addition, the operating model is simple and available to all users. We conclude that application of the Bristow-Campbell model adapted, it is an instrument of great utility to generate a comprehensive database of available solar radiation in Junín region.
