One of the continuous expenses that a business needs to make is its utilities. Therefore, investing in Industrial Solar becomes critical for a business’s survival, especially when tariff rates are rising at an alarming rate.
However, when it comes to Industrial solar installation, one factor needs considerably more time for research and critical decision-making. That factor is the choice of industrial or commercial solar panels. There are many high-efficiency solar panels available for industrial use.
In this guide, we shall discuss various solar systems, best solar panels for industries and some tips to help you purchase the right solar panel for your project.
Which Is The Best Industrial Rooftop Solar System?
The components of a commercial solar panel installation depend on which system you choose. Let’s explore the three types of solar systems for commercial projects.
On-grid solar system
An on-grid solar system connects with the local grid. Thus, if the solar panels don’t generate sufficient output, you can pull it from the grid. However, if you have energy surplus, you can pass it to the grid through net metering in exchange for credits. These credits are used to reduce your electricity bills in the future.
One of the primary challenges of the on-grid system for industrial solar projects is its dependency on the grid connection. If the grid connection is cut, your system won’t work either.
Best For: Any business in an urban area with a strong grid system.
Off-grid solar system
An off-grid solar system is a completely independent solar system without any connection to the local grid. This system includes the solar batteries, or BESS (Battery Energy Storage System), that store the surplus energy for the night. Thus, you can use that energy when the solar panels aren’t working or the output is insufficient.
Best For: Industrial buildings in a remote area with an unstable power supply.
Hybrid solar system
A hybrid system has features of on-grid and off-grid systems. Here, your industrial solar system has a net metering connection to the grid and a battery to store the surplus energy. While this system is expensive, it can provide you with a consistent energy supply no matter what.
Best For: Any business that wants an independent system but also benefits from net metering.
Types Of Solar Panels For Industrial Solar Systems
The industrial solar panel price is one of the most significant factors in total solar installation cost. Therefore, choosing the right one matters. Here are the top 4 solar panel technologies suitable for commercial solar panel installation.
Mono PERC Bifacial Solar Panels
Monocrystalline PERC (Passivated Emitter and Rear Cell) panels have been a classic choice for industrial projects for decades. Now, it comes with a better twist: bifacial solar panels.
In Mono PERC Bifacial Solar Panels, the rear end of the traditional panel also has solar cells. Thus, it generates more electricity compared to the monofacial solar panels as it has 19% to 22% efficiency. It is a cost-effective solar solution for businesses that want a high-efficiency system under budget.
N-Type TOPCon Solar Panels
N-Type TOPCon Solar Panel is a classic choice for an industrial solar project. It includes additional layers and N-type technology that increases its efficiency to almost 24%. It is a medium-range solar panel technology, ideal for all commercial and industrial projects. Its durability makes it perfect for rooftop industrial projects.
N-Type TOPCon Bifacial Solar Panels
N-Type TOPCon Bifacial Solar Panels are a high-efficiency version of the traditional TOPCon model. Here, there are solar cells on the rear end of the panel. Thus, it generates 30% more electricity compared to normal industrial solar panels. If you have a reflective surface, this solar is the best choice for you. These are the Best Solar Panels for Industrial Solar Projects with limited space for solar mounting.
Half-cut Bifacial Solar Panels
In half-cut solar panels, the solar cell is cut in half to improve the overall performance. A few benefits of half-cut solar panels are reduced power loss, better efficiency, and better ROI. The two halves of the cells have separate connections. Thus, there is lower current flow and less wastage.
If you have an open ground or a space with sufficient sunlight exposure and a reflective surface, half-cut bifacial solar panels are the best choice for you. Its efficiency depends on whether you choose monocrystalline PERC or TOPCon solar panel technology.
How To Choose the Best Solar Panels For Industrial Solar Projects?
Choosing Commercial Solar Panels can be overwhelming. So, consider the following things before choosing a solar panel for your industrial solar project.
Identify the energy consumption pattern
The number of solar panels for industries depends on their expected output. For that, you need to determine what your energy consumption is. Analyze your recent 12-month consumption from the electricity bills. It will give you an average. Add a few more watts for future growth and high-demand days. This will help you choose a technology that gives you the desired output that matches your needs.
Availability of space for solar mounting
Industrial solar projects take up significant space. Therefore, whether you are choosing a rooftop or a ground, ensure that you have sufficient space. If you have a limited space, invest in high-efficiency technology like N-Type TOPCon Bifacial Solar Panels. It has higher efficiency, leading to better output that matches your needs. Sunora Solar can help you find the right commercial solar panels based on your consumption needs, space, and budget. Reach out to know more.
Degradation rate of the solar panels
Every solar panel module degrades over time. In industrial projects, this degradation rate matters the most because of its impact on overall output. A 0.4% degradation over 25 years is different from when it’s 0.5%. Therefore, ask for the degradation rate estimates before committing to a solar system.
Certifications
The solar panel manufacturer must have BIS and IEC certificates to ensure that the panels meet all the necessary safety and compliance standards. Choose a manufacturer who is registered with the ALMM of the Ministry of New and Renewable Energy (MNRE).
Cost of ownership
Lower initial cost of solar panel may seem tempting, but it could cause repetitive maintenance and repair costs. Therefore, when choosing an industrial solar system, consider the cost of ownership. It must include the cost of industrial solar installation, maintenance, repairs, and more. A reliable solar panel supplier provides operations and maintenance services to optimize your system so it works at its best potential.
Maintenance needs
Every solar system requires regular maintenance to function at its desired efficiency. You can do simple cleaning of the surface at regular intervals. However, you must schedule a professional maintenance checkup to ensure that all the internal components of the system are working well. This also helps you identify any faults in the early stage and reduce the damage and repair cost.
