If you can pay your business’ electricity bills without any problem, you can definitely do the same when you switch to a commercial solar system.
Unlike home solar systems that operate most of the time, businesses usually utilize electricity during office hours. Here are other things you need to know about solar power for businesses:
There Are Different Size Breaks for Commercial Solar Systems
Less than 30 kW
These systems are almost the same as residential systems because of the hardware and grid connection. Therefore, companies that do residential installations can install this for businesses without hiring a specialist.
For commercial solar systems this size, it needs unique systems to ensure the safety of the grid from the electricity that can be produced. It also needs special consent from your area’s electricity network to attach to the grid.
Therefore, it is recommended to get a specialist for businesses that require this size. This size is usually seen in small retail businesses, office buildings, and small-town clubs.
Over 100 kW
If your business is over 100 kW, you are not qualified to avail of the STC rebate. Nevertheless, you can get LGCs which is a subsidy. You can get this annually, and it is based on the energy your system can produce.
Claiming it is also added work because you need to have a special meter and will need to send a report of energy generated annually. This system is usually seen in big offices, small to medium factories, wineries, and hotels.
This system is very huge, so it is best to seek assistance from an expert who is familiar with particular engineering requirements for commercial systems as big as this. You can usually find this in solar farms or big shopping malls.
Attach Big Commerical Power Solar Systems to the Grid
In Australia, when you install systems that have a 30kW size, it is crucial that you see in the paper the approval of the network for installing this system. Each solar power that is attached to the grid needs to be approved.
For bigger commercial systems, sometimes, the approval has conditions. For instance, once a 55kW system is approved, there will be a 10kW set for export which can effectively limit devices.
This is important to know because the expenses for the equipment and other costs are not cheap. Moreover, the export limitation may also have an effect on your expected savings. Some not-known commercial installers may not mention this because they have not considered it in their expenses.
Solar Expenses and Paybacks
A quality solar power system is over 30kW or less than 100kW. The cost for this can be around $1,000 to $3,000 for each installed kW in Australia. When you have power optimizers or microinverters, it can be 15 to 20% more expensive than a central inverter system.
For 20 to 30 kW, it can be around $700 for each kW. It is cheaper because of less engineering expenses and network safety required.
