Observing the Sun Unnecessarily Averted
In the realm of solar power, a cost-effective alternative to traditional methods is gaining traction. This alternative involves arranging solar panels east-west, rather than employing solar trackers that follow the sun's movement.
According to expert Xavier Derdenback, the current low cost of solar panels makes the installation of tracking arrays a waste of money. Instead, he suggests building a system with panels facing east and west, a choice that proves to be more financially sound.
The beauty of east-west arrays lies in their simplicity. Consisting of parallel strings of solar modules set in opposite directions—one facing east and the other west—these arrays efficiently capture sunlight from dawn until dusk, much like a tracked array.
The advantages of east-west arrays are manifold. Firstly, they boast lower installation costs compared to tracking systems due to the absence of additional mechanical components and maintenance requirements [2][5]. Secondly, the reduced cost of solar modules further magnifies the cost savings associated with using simpler fixed arrays [1]. Lastly, east-west arrays take up less land compared to tracking systems for a given power output, making them attractive in areas where land is limited [2].
That being said, it's essential to consider certain factors before deciding. For instance, while tracking arrays may produce more energy per panel, the cost savings from using east-west arrays often outweigh the increased energy production benefits [2][5]. Additionally, in regions prone to severe weather like hail, high-impact-rated modules might be necessary for east-west arrays to ensure durability [1].
In conclusion, east-west solar panel arrays are increasingly becoming a cost-effective alternative to traditional tracking arrays. With the current low prices of solar panels and the ease of installation, they present an attractive option. Yet, the choice ultimately depends on specific project needs, such as energy production goals, land availability, and local weather conditions.
In the context of renewable energy, the financial industry is increasingly investing in east-west solar panel arrays, which offer lower installation costs compared to tracking systems due to reduced mechanical components and maintenance requirements. Furthermore, the technology sector plays a crucial role in enhancing the efficiency of these arrays, with innovations contributing to the capture of sunlight from dawn until dusk, like a tracked array, but with less energy input.
