Solar Energy Project Development Utilizing Bifacial Module Designs

Overview

The sole purpose of this report is to increase the power output of the bifacial solar module design. We are presented with the task of testing different albedos in other to find the albedo that produces the highest bifacial gain.

Objectives

-The final design of this project will illustrate a contrast between bifacial and monofacial solar modules.

-In order to draw a proper conclusion, energy production, accuracy, and costs will be analysed in this research.

Approach

-We picked a locale that will be highlighted for the region involving the solar panels. From this, we are able to create many segments. Once this first step was done, we had to decide the type of solar panel we wanted.

-In other to properly analyse our results, we used Helioscope to model bifacial modules

-We used MATLAB was used to generate multiple graphs off of the differing variables presented and Excel was used to generate an accurate profile of the bifacial model.

-To further analyse our results, we decided to use an equation that incorporates the albedo, reflectance of the ground surface material, and the increase in energy gain from the module being bifacial. However, the equation we found did not include a reliable source, so we disregarded it.

Outcomes

-The team calculated the bifacial gain for albedos ranging from 0.1 to 0.5, which is within the range Oriden Power usually develops their solar farms with a bifacial gain of 0.2 on grassy surfaces.

-The highest bifacial gain calculated is therefore that of 0.5 albedo at 12.2%, while the lowest gain is 2.4%

-The most realistic bifacial gain will be around 5% since it corresponds to an albedo of 0.2 which is the closest to the values Oriden works with.

-A tilt angle of 20 degrees may be the most optimal option for a bifacial panel in energy production. The intermediate tilt angles from about 20-25 degrees show more of a flatline in the summer months, but have a less of a decline in the other moths compared to the lower tilt angles. This could be a cause for consideration as the most appropriate tilt angles at about 20 degrees.

-Although peak energy output is lower than 10 and 15 degrees, there is an extended period of time for which an elevated output level is generated. These kinds of considerations need to be considered when yearly energy production is being considered.

-This project was conducted through a rigorous trial and error process done through multiple software systems, based on the results and feedback from the client, the project was successful.
