In Australia, with so much talk about reducing electricity costs, many households have switched to home solar systems. They are efficient, eco-friendly, and an investment worth making. The earn-back time on solar installs is now lower than ever because the cost for solar panels is the lowest it has ever been. If you install panels for your residence, they will pay for themselves within 3-4 years. The savings that you get via this investment comes in the form of freedom from electricity bills. But, what if the roof solar panels are covered by shade, like that of a cloud cover?
How Does Shade Impact your Home Solar Panel System?
When people choose to believe that shading doesn’t have a substantial impact on the solar panel’s output, they’re mistaken. Shading, be it from a tree, cloud cover, or a nearby building, reduces the solar system’s effectiveness. Moreover, the belief that if some modules are under shade, the rest of the solar panels will function optimally is typically also a myth. Even if a single solar plate doesn’t get appropriate sunlight, all the other solar panels in an arraymust adapt to the change.
So, the overall output variance is quite notable even when there’s an occurrence of partial shading. The best way to prevent these losses is by taking precautions during installations and ensuring that your solar panel system gets maximum sunlight.
Techniques that Can Prevent Losses Due to Shading
Here are a few methods that you can use to prevent shading over your solar power system:
1. Pick a Location that has the Highest Sunlight Exposure
Nobody knows your house better than you. But, before the installation of a home solar system, consult with a shading consultant regarding the best location for installation. Cloud cover, for now, is an avoidable problem, and companies around the world are working on new systems, like the “super black panels” to counter cloud cover shade. Consult with local solar technicians to know more about the surroundings and talk to your neighbors. This way, you’ll come to know about the buildings that’ll elevate in the future and the direction of trees that’ll soon become enormous.
2. Select the Solar Panel with Micro-inverters
Solar panels that come with efficient micro-inverters might cost you a little extra, but they offer a more stable power supply. The problem with shade is that even when it’s partial, it reduces the whole system’s overall output. Micro-inverters rectify this problem by converting DC (direct current) into AC (alternating current). For that, you’ll need a micro-inverter for each solar panel, which will transform the circuit into a parallel one, preventing the poor performance of one solar panel from impacting other solar panels.
3. Make use of Power Optimizers
If your location is such that shading is bound to happen for a large part of the day, Power Optimize Shading isn’t suitable for your home solar system. But, nobody is above mother nature, and you need electricity even when it’s cloudy, or when your panels are partially shaded. Power optimizers divert the DC electricity from each panel to a string inverter, ensuring that the solar panels operate individually and provide independent output. All of the generated power is collected separately and integrated before being supplied.
To Sum Up Note that these tips will help you optimize your power output with solar by preventing shading from occurring. With advanced micro-inverters and optimizers, you can ensure an uninterrupted power supply even when the solar plant isn’t exposed to complete sunlight.
