Abstract
Concentrating photovoltaic (CPV) system is an application of PV devices introduced with the aim of reducing the cost of BIPV systems through the use of an optical element to concentrate or focus the solar radiation from a large area, into a smaller area to which the solar cell is attached, thus reducing the overall cost by saving expensive PV material. This paper aims at presenting the simulation results of an annual prediction for a system comprising of CPV based on the Rotationally Asymmetrical Compound Parabolic Concentrator (RACPC) and compared it with a non-concentrated PV module installed in Bogota, Colombia under different weather conditions. The yearly energy yield of the CPV module was calculated to be 480 kWh whereas the non-concentrating PV module had a drop in the output - almost half of the CPV module output, having a final value of 231 kWh. This indicates that the RACPC can increase the output by a factor of 2.08. This study demonstrates that a CPV system can be used as an alternative to a conventional PV system; as it offers a lower cost without compromising its performance.

After the latest global warming meeting in Paris the 12th of December 2015, 195 countries agreed with the United Nations (UN) to work with the aim to keep the global temperature increase below 2 oC and to join efforts to try to keep the temperature increase below 1.5 oC [1]

Summary
After the latest global warming meeting in Paris the 12th of December 2015, 195 countries agreed with the United Nations (UN) to work with the aim to keep the global temperature increase below 2 oC and to join efforts to try to keep the temperature increase below 1.5 oC [1]. Energy efficiency implies delivering the same amount of services for less energy input or more services for the same energy input. This is important to reduce CO2 emissions and brings multiple economic benefits such as reducing fuel poverty, enhancing energy security and improving public health [3]. Around 146 countries have developed and implemented some kind of energy efficiency policy such as policies for electricity, policies for cooling, renewable energy transport, heating; and city and local government
