Project Summary |
||||
By 2050, the demand for accessible energy is predicted to double the needs of 2009. According to Lewis and Norcera in their evaluation of the sustainable energy, solar power is the only viable noncarbonaceous source. The SolArray is a novel self-tracking passive photovoltaic diode orientation system that addresses the challenges faced by conventional photovoltaic panel arrangements, which require maintenance and are affected by wind. The SolArray is capable of orientation positioning for angle alignment accuracy, accomplished through the individualization of each row of diodes’ performance by micro-tracking orientation, ensuring that a minimal amount of space is occupied while optimizing the photovoltaic array. This research utilizes dye-sensitized photovoltaic diodes, as they are more flexibly producible, which are thus mounted on a rotational structure that possesses flaps for harnessing wind movement. Notches that retract using push-pull solenoids limit the motion of the cells at certain times after sunrise, detected using a digital logic gate and a comparator. The timer circuit uses a programmable timer chip with a resistor and capacitor. A performance investigation was conducted under a seven-hour exposure with rotational lighting sources. According to its standard output, the SolArray, on average, maintained virtually 100% efficiency with a small range of angle alignment accuracy values and generated 40% more energy than a conventional single-exposure system. The SolArray will also allow buildings to install photovoltaic arrays that are more accommodating to wind resistance. It is easier to calibrate and maintain than a conventional system, enabling developing countries to afford localized solar panel systems, improving their potential for sustainable development. |
