What You Should Know Before Buying Commercial Solar Panels

by | Oct 10, 2022

Commercial solar panel
Significantly larger than their residential counterparts, commercial solar systems are the perfect investment for all manner of businesses. As many businesses operate primarily during the day, they are primed for optimal solar collection and usage.

The installation of commercial solar panels can both reduce electricity costs and help establish your business as a more eco-friendly and sustainable brand.

Commercial solar system sizes

Designed for everything from small businesses to large companies and warehouses, commercial solar systems provide a much larger supply of electricity than their residential counterparts.

  • PV Systems with wattage up to 40kW are suitable for smaller businesses or those that do not use high volumes of electricity. They also follow the same connection requirements as residential systems, which can simplify installation.
  • Commercial systems with a capacity between 40kW and 100kW are a popular installation choice for larger businesses. However, due to the increased potential energy generation, permission has to be granted by your local electricity network (DNSP) in order for your system to be connected to the grid.
  • For businesses with considerable energy usage, commercial systems are available with over 100kW of capacity.

    • The optimal solar panel size will be determined by the day-to-day electricity consumption of your business. Luckily, the specialists at Solar System Australia can help you choose the best commercial solar system to meet your business needs.

    More solar cells per panel

    As commercial spaces generally have more roof space than a standard residence, the panels used for commercial installations feature a higher number of solar cells. Commercial solar systems generally use higher voltage power panels to save roof space.

    As a result, the complete system can generate more power using a comparatively lower number of panels. Needing fewer panels can potentially lead to lower installation costs.

    Types of commercial inverters

    Three main inverter options are available for commercial enterprises, determined by your power preferences, business setup, and advice received from a reliable commercial solar expert.

  • Microinverters: Microinverters are placed on the back of each individual panel to ensure that each module is providing optimal solar output. Microinverters offer improved performance and safety but come at a higher cost.
  • String: The most common and cost-effective option, string inverters connect panels together in ‘strings’, which are connected to an inverter box. Depending on the number of panels, some installations may require multiple string inverters.
  • Central: As the name implies, central inverters are a single point of control for large solar setups. They are highly efficient but are a lot larger than other inverter options.

    • Solar Feasibility Study

    Working with experienced solar experts, a Solar Feasibility Study can be created to determine the benefits and viability of a commercial solar panel installation.

    A Solar Feasibility Study can assess financial value, optimum capacity and system size, current electricity usage, and business utility. As with residential solar installations, it’s crucial to discuss your requirements with multiple solar experts to find the most feasible solar solution.
