Solar energy is an excellent renewable energy source, giving sufficient environmental and economic advantages. Nevertheless, it has a significant limitation: a solar panel produces more power when directly facing the sun, but the sun is moving in the sky. That’s why, solar panels turn to be more effective at noon while they get direct sunlight; however, suffer decreased production in the early morning or at the afternoon’s end.
Alongside the daytime, other factors also impact the sun’s position in the sky:
Regularly sun-hours in a provided location change as per the season, and the usual path considered by the sun in the sky likely to rise in summer and fall in winter.
The sun turns to be lower in the sky for the nations far to the south or north. Besides, in the tropics, the regular path of the sun in the sky is really high and the sun may be located straight upward at noon.
With aforesaid factors, it’s just impossible to capture available solar energy in a provided geographic location with a fixed PV system. Modifying tilt amid the year is possible; however, not practical, and the expenses of continuously modifying the system exceed the advantages.
Luckily, automatic Solar Tracking technology is now commercially available. Solar tracker gets inspired from nature, and usually, operates like a mechanical sunflower: it can tilt and rotate solar panels so that they can always face the sun directly, at every location, from sunrise to sunset, and all over the year. Geographic location is unimportant, as automatic solar tracker is basically equipped with GPS technology which enables them to measure the ultimate tracking path for each single day of the year.
Top advantages of solar tracking technology:
Solar tracking technology can boost the efficiency of the PV cells by up to 30% compare to a ground system and 45% in comparison with a roof-based system. Thus, under the proper conditions, a solar tracking system with 1000W of installed capacity will have the similar output like a fixed roof system with a capacity of 1450W. It has many advantages:
- The first investment is eliminated for a new project, as the target of energy generation can be met with lesser solar panels. The current energy output is increased with an existing PV system. The impact, in either case, is that the solar installation provides a bigger return on investment.
- The PV system needs less space. It can be a great advantage when the place available for the solar system is not unlimited. Especially, a solar tracking system gives more energy per square meter of solar panels. This technology is predesigned for the standard solar cells’ accommodation, which enables it for integrating simply with several commercial solar panels. Every grid tie-in or battery bank just installed can continue working while a PV system is fixed on a solar tracker.
