Installing a 6kw solar power system is a very sensible decision for a family of 5 to 7 people as it basically meets the daily electricity requirements and with the addition of a battery back-up it almost completely eliminates the reliance on the mains. If you consider the economic aspects of the battery can be properly added, so that the daytime PV power can supply power to the load at the same time to charge the battery, the battery at night to provide power, so that every day a cycle. Maximize the use of solar energy.

How Much does a 6kw solar system produce?
A 6kw solar power system generates between 18kWh and 33kWh of electricity per day, mainly due to the different amounts of solar radiation at different latitudes and altitudes. The optimum temperature for PV to generate electricity is 25°C. Too high or too low a temperature will affect the amount of electricity generated.
You can refer to the image below to know the peak sunshine hours per day in your area to calculate the amount of power a 6kw system can generate in your area.
For example, if the area is 5kwh per day, then the 6kw can generate 5×6=30kWh per day.

6kw Solar System Size
The size of a 6kw solar system is approximately 30m² (322ft²), based on the use of 12 pieces of 550watt solar panels. If smaller-sized solar panels are used, or if the solar panels need to be installed in two rows with space left between each row for maintenance and optimal performance, the installation size will be slightly larger. This additional space ensures that the solar panels can operate efficiently without shading issues and allows for easier access during maintenance.


6kw Solar System Price
The price of a 6kw solar power system is between 1400USD and 3600USD. note that grid-tied systems are much cheaper because they don’t come with batteries and because of the simplicity of the construction of the grid-tied inverter. Also, off-grid system and hybrid system prices are based on the size of battery capacity you need.
Model | Price |
---|---|
6kw on grid solar system | Around 1400USD |
6kw off grid solar system | Around 3100USD |
6kw hybrid solar system | Around 3600USD |

6kw Solar System Load Capacity
A 6kw solar system is capable of supplying electricity to a load with a total power of up to 6kw. It can support the operation of 5HP motors, such as air conditioners, fans, washing machines, and other household appliances. This makes it a versatile solution for meeting the energy demands of a medium-sized household or small commercial setting, ensuring reliable power supply for essential appliances and reducing reliance on grid electricity.

Factors Affecting Efficiency of a 6KW Solar System
6KW Solar Power System FAQ
A 6kw solar system typically consists of 12 units of 550watt solar panels or 16 units of 400watt panels. Commonly used solar panels come in various wattages, including 550watt, 450watt, and 300watt. Higher wattage panels are often preferred for their efficiency and space-saving benefits, especially when roof space is limited.
One or two 10kWh batteries are generally sufficient for most households with a 6kw solar system, but if your power usage is significantly higher at night, you may need to add more batteries. To determine the exact capacity and number of backup batteries required, assess your nighttime energy consumption and factor in the depth of discharge (DoD) and efficiency of the batteries to ensure you have adequate power reserves.
A 6kw solar system can generally meet the electricity needs of a typical household, especially if the home is energy-efficient. It can cover most daily usage, including appliances like refrigerators, washing machines, and lighting. However, factors such as local climate, roof orientation, and household energy consumption patterns will affect the system’s ability to fully meet all electricity needs.
A 6kw solar system doesn’t necessarily require regular battery replacement. The lifespan of batteries depends on the type used—lithium-ion batteries generally last longer than lead-acid batteries. Proper maintenance and usage patterns can also extend battery life.
Yes, a 6kw solar system can be upgraded in several ways. You can add more solar panels to your existing system if your solar inverter can handle the additional power. Another option is to install microinverters, which allow for more flexibility and can be added to individual solar panels without affecting the entire system.
