The payback period for installing solar panels in factories depends on several factors. The main factors that affect the payback period include:
Size of the Solar System:
Factories with larger solar systems may have a longer payback period, but if the electricity consumption is high, the payback can still be quick. A slow payback could be due to installing a system that is too large for the factory’s energy needs.
Installation Costs:
The installation cost of solar cells includes the cost of solar cells, inverters, batteries (if applicable), and installation labor. These costs vary based on the quality of the equipment and the system size.
Electricity Savings:
If a factory uses a lot of electricity, installing solar cells can significantly reduce electricity costs, leading to a faster payback period, especially if the factory is located in an area with high electricity rates.
Electricity Production and Usage Ratio:
Factories that consume energy during the day, when solar cells generate the most electricity, will be able to reduce their electricity costs effectively, which helps achieve a faster payback than factories that consume more energy at night.
Typical Payback Period
Small to Medium-Sized Factories:
Generally, small to medium-sized factories that install solar systems can break even within 4-6 years if they regularly use electricity during the day and can significantly reduce their reliance on the main grid.
Large Factories:
Large factories that install large solar systems can break even within 4-6 years or even sooner, depending on electricity rates and their energy usage.
