How to choose a suitable Commercial and industrial PV system

Solar Panel

Today’s commercially available photovoltaic panels for commercial and industrial use are mainly monocrystalline solar panels. For special requirements and usage scenarios, we can also offer double-sided double-glazed and all-black photovoltaic panels. They are more efficient, have a very good quality and a 25-year warranty.

Today’s commercial and industrial photovoltaic panels are mainly high-power photovoltaic panels, which use 210mm cells and have a power of around 600W.

The choice of total PV panel power depends on the electricity consumption of your factory or shopping mall. If your electricity consumption is 320kWh, you will need a PV system with 100kWh/3.2h = 100kW. (3.2h is the assumed effective power generation time per day, which depends on the local light intensity. The better the light intensity is approximately, the longer the effective light time will be.)


Solar Inverter

Commercial and industrial PV inverters are available in off-grid, grid-connected and hybrid types, as are residential PV inverters. If a factory or shopping mall, for example, relies solely on a PV system for its electricity generation, then an off-grid system with batteries is the way to go. If you need to sell electricity to reduce costs, you will need a grid-connected system. If you need both, you will need a hybrid system.

Commercial and industrial PV inverters are a bit more powerful, probably from 50kW upwards to several hundred or thousands of kW. you can see more of the previous complete solutions in our case studio.

The amount of power you choose depends on the sum of the total loads your plant is working with at the same time. You can refer to this formula: sum of resistive load power + sum of inductive load power X 3. However, too much power will increase the cost, and we can also reduce the starting voltage of inductive loads by using a reduced voltage start.


Solar Battery

The vast majority of commercial and industrial batteries are rack-mounted, high-voltage lithium batteries, which require a relatively large battery capacity because of the high power consumption. Lithium batteries are more stable and reliable.

We usually use standard battery packs of 10 kWh or 43 kWh in series and parallel to obtain the required voltage and capacity for the user.

This is related to factors such as the local weather and the amount of electricity needed at night. The more power required at night and the longer the rainy weather, the more energy storage is required. The amount of battery discharge per unit time also needs to be considered to ensure you can drive the load properly.


Control Box

The control box is essential for commercial and industrial PV systems as more panels will be used. Often several control boxes are selected for a system to ensure better management of each PV panel.


Cable & Connecter

Our technical engineers will provide you with conventional cable runs and connectors depending on the size of your system, which will suit most needs. If there are special circumstances they can also be customised for you on a case by case basis.


Bracket

Commercial and industrial PV systems are available as rooftop PV systems and ground-mounted PV systems. They can be installed on the roof of a factory or on open ground. We have solutions for different roof and ground conditions.
