Solar systems are an array of multiple photovoltaic solar panels that convert solar energy into electricity. They are the source of clean and renewable energy that requires less maintenance and has no carbon emissions. Thus, they possess the minimum threat to the environment and public health. Solar panels minimize your dependency on the local power stations.
Nowadays, every individual is trying to embrace solar energy. Commercial enterprises are using solar systems to power their buildings. Not only does switching to solar systems reduce their power bills, but sets an example for displaying a commitment to more environment-friendly energy sources.
So, how different are the solar systems that power the commercial spaces or the ones installed for residential homes? Are they made or customized differently?
Considering a commercial building versus a residential building, the most significant difference will be the overall scope of the system. A single residential building might have four people, whereas a commercial building could contain hundreds of people. Solar panels for commercial buildings are bigger than residential ones, as they require more energy. Hence, size is the first difference between the commercial and residential solar systems.
Size
The commercial solar systems comprise 96 solar cells with a dimension of 78 inches by 39 inches, whereas a residential solar system has 72 solar cells measuring 65 inches by 39 inches. The residential solar systems having fewer solar panels produce less electricity and consume less space but still lead to huge savings. Hence the size difference does not make any sense as a residential property will not have similar energy requirements as the big commercial ones.
Installation
Both residential and commercial solar systems are installed in the same way using a bolted racking system that is globally recognized as safe and efficient. Generally, a commercial solar system is easier to install as they usually have flat roofs, and panels can be fixed using a ballast mounting system. With residential systems, most installations will be on a pitched roof, hence will require a penetrating racking to mount the system and bolt it on the roof. On the other hand, commercial solar systems take around a month to complete the installation, while the residential system takes two or three days.
Color/Shade
Solar panels used for commercial purposes are generally white in color, and residential systems are available in black or white color. Residential customers opt for black colored panels with black backing, while commercial customers go for black colored panels with white backing.
Cost
Commercial solar systems have higher costs and lower cost per watt. Another key difference between residential and commercial solar systems is the cost component. On a panel-by-panel basis, commercial systems will be costlier as they are larger and have more storage space than residential. It is also crucial to know that the solar panels are not purchased individually, and therefore the cost of a solar system is calculated based on its power calculation. As the solar systems are sold per kilowatt-hour, they cost the same for residential and commercial if given equal kWh and production.
Panel placement
There are several options for commercial properties to install solar systems compared to residential properties. Commercial systems can be installed on their rooftops and also can expand creatively, taking advantage of solar-paneled parking lots or open ground installation on surrounding land. However, the residential solar systems don’t have more options like commercial ones as they have limited home size and neighborhood restrictions.
Wrapping Up
Lastly, if you are thinking of installing a solar panel at your home or commercial space, make sure you clearly understand the differences and then start the installation process. Although commercial and residential solar systems differ in some ways, they have one thing in common, saving money by using the free energy of the sun and helping to reduce global warming.
