Solar Panel: During the summer season, the use of electrical appliances in homes increases, leading to higher electricity bills. This rise in costs can impact the household budget. That is why many people are now opting for solar systems; however, before installation, a common question arises: what capacity (in kilowatts) is the best and most beneficial choice?

If you are also confused about whether to install two separate 5 kW systems or a single 10 kW system, it is important to understand the details of both options before making a decision.

Which system is better to install?

It involves lower costs.
Maintenance is also easier.
It can effectively handle heavy loads.

Regarding the installation of two separate 5 kW systems, you might need to install two inverters. Additionally, you could incur separate expenses for wiring and installation. In contrast, if you install a single 10 kW system, you only have to incur these costs once.

Which system can handle a heavier load?

This depends on the electrical appliances in your home and how many you use simultaneously—for instance:

If 3–4 air conditioners (ACs) run in your home.
If a water pump motor is also operated.
And if high-power devices are used.

In this case, a single 10 kW system would be better for you, as it can support these appliances more effectively. Conversely, a 5 kW system might not prove as efficient under heavy loads.

Does installing two systems require more maintenance?

A key advantage of installing a single 10 kW system is that it requires fewer inverters and other components, resulting in lower maintenance costs. In contrast, if you install two separate 5 kW systems, you would naturally need to maintain both, and the costs could be higher compared to a single 10 kW system.

Important points to consider:

If your household has high electricity consumption, a 10 kW solar system is a suitable option.
This requires ample space on your rooftop.
In terms of maintenance and performance, a 10 kW system can prove superior to having separate 5 kW systems.
However, if you have a limited budget, you can start with a 5 kW system.
You can always upgrade the system later if the need arises.
