Commercial solar panels in NJ or other places are usually larger than residential solar panels in NJ although the size difference depends on application actually. Basically, commercial ones are about a foot wider, featuring 96 cells instead of the 72 cells on residential panels. And because they are ideally larger, commercial solar panels tend to be more efficient at producing electricity than residential ones: they are about two percent more efficient compared to residential ones. According to other data, commercial panels manage an efficiency of about 19.6% compared to residential panels’ 18.1% efficiency.
In regard to production issues, commercial panels have more cells and will therefore produce more power than residential solar panels. When buying any solar panel, it is advisable to look for one that will supply adequate power without having to join many panels because the later would actually compromise on efficiency or increase power loses.
Although commercial solar panels are more costly, ideally solar is sold per kilowatt hour and therefore there is usually no cost difference between residential or commercial panels as the consumer. Besides the cost of the actual panel, there will usually be installation costs. Some companies will sell panels with packages including installation costs, which mean you do not have to pay separate costs for installing or look for a specialist. Otherwise, this is an important consideration when buying a solar panel for both commercial and residential use.
However, it is obvious that when selecting a solar panel, the size depends on a few factors such as the efficiency of the panel vis-à-vis the amount of power it gives. Other factors relate to your needs such as what power you actually need in your home. Sometimes you might desire a larger panel, but there might be limitations related to the size of your roof.
In many cases, there are some differences with installation mechanics. This is because most of the roofs of commercial buildings tend to be flatter than residential roofs. Installation on roofs is done using a bolted racking system. That is for the case when the installation is being done on top of the roof. Most commercial panels are installed on a flat roof and thus a non-penetrating ballasted mounting system is used. This will ease and quicken installation. There are some cases when that is not necessary for both but especially for industrial applications.
But some complications and difficulties might result when installing commercial solar panels in NJ because in most cases, they involve combining upwards of one hundred panels while residential installations involve combining between eight and sixteen panels.
In fact, commercial solar panels can take longer to install than residential ones but that again depends on the expertise and number of people and kind of techniques involved.
In regard to aesthetic differences, white panels are common for both residential and commercial applications. Remember that panels can be either white or black. Commercial panels come mostly in white backing, meaning there will be a visible white grid pattern around each cell.
