Abstract
There is a large number of roof mounted Photovoltaic (PV) power generation installation systems for domestic applications. However, the roof inclination angle and the direction are not only fixed but also not at the recommended values. As a result, consumers are often misled because the published output power generated from such systems is given for ideal conditions.
The project has investigated the cost and the performance characteristics of two different makes of PV panels and their power output due to variations in inclination angle, direction, temperature, shading and aging effects.
A dual Panel Frame was constructed to carry out the tests on the two different PV modules. The project uses a data acquisition Lab-Jack U6 device to collect data and analyse the effects of the mentioned variables and compares their output with variations.
The need to understand the effects of these variations is important particularly to consumers and engineers and the information in this report is beneficial to them.
While there are some published information, one of the interesting findings in this dissertation is the effects of shading on panels, the report highlights the energy generated from a particular PV module or a system compared to its rated value. Other information presented allows consumers to make better judgement about buying their own PV systems.
