How much does a 15kw solar system produce?
A 15kw solar power system generates between 45kWh and 80kWh of electricity per day, and this varies greatly from region to region due to the different levels of solar radiation per day depending on altitude and latitude.
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 15kw system can generate in your area.
For example, if the area is 5kwh per day, then the 15kw can generate 5×15=75kWh per day.

15kw Solar System Size
A 15kw solar system typically occupies an area of about 67m² (720ft²) when configured with 27 pieces of 550watt solar panels. This calculation is based on the standard dimensions of these high-efficiency panels. However, the exact installation area may vary depending on factors such as roof or ground type, shading, and orientation. It is essential to carefully assess the available space and design the layout to maximize energy production.
15kw Solar System Price
The price of a 15kw solar system is from $3,500 to $8,000 and its main costs are the solar panels, the inverter and the batteries, of which the batteries make up a large portion. If you don’t need battery backup, just choose a grid-tied system. You can contact us to get a customized solar design solution and quote.

15kw Solar System Installation
What Can a 15kw Solar System Run?
A 15kw solar system can power a wide range of electrical loads totaling up to 15kw, including both single-phase and three-phase equipment. For instance, it can support multiple air conditioners and can handle electrical equipment up to 10 horsepower. This makes it suitable for medium to large residential or small commercial applications, provided the system is well-configured to manage peak demand and energy storage.
15KW Intelligent Energy Backup System
1. System initialization: The energy management system (EMS) starts and detects the system status, confirms that no solar panels are connected, and enters the backup power supply mode.
2. Battery energy storage activation: EMS commands the power conditioning system (PCS) to extract DC power from the battery energy storage system.
3. DC conversion: PCS converts the DC power provided by the battery into AC power through an internal inverter.
4. AC power distribution: The converted AC power is transmitted to the AC bus as the power source for household loads.
5. Load power supply: The AC bus distributes power to household loads to meet daily electricity needs.
6. Real-time monitoring: EMS monitors the electricity consumption of household loads and the remaining power of battery energy storage systems in real time through electricity meters.
7. Power management: EMS dynamically adjusts the output power of PCS based on battery power and load demand to optimize battery life.
8. Low battery warning: When the battery level drops to the preset threshold, EMS sends a low battery warning to the user through the communication cable.
9. Grid backup start: When the battery is low and unable to meet the load demand, EMS switches to grid power supply mode to obtain electricity from the grid.
10. Grid interaction management: EMS monitors the power supply situation of the grid through electricity meters, ensures stable power supply for household loads, and records grid electricity consumption data.
11. Data synchronization and analysis: EMS synchronizes system operation data to the monitoring platform through communication cables for data analysis and optimization strategy adjustment.
12. System standby and preparation: During the grid’s power supply period, EMS maintains the system standby state, waiting for battery charging or other energy sources to be connected.
How does the power generation of a 15kw solar system change in different seasons?
The power generation of a 15kw solar system varies in different seasons due to factors such as sunshine duration, solar radiation intensity, temperature, and weather conditions.
1. Spring:
As the sunshine duration gradually increases, the intensity of solar radiation increases, and the power generation begins to rise, but it is still lower than in summer. The moderate temperature in spring is conducive to maintaining good power generation efficiency of solar panels.
2. Summer:
Summer has the longest sunshine hours, the strongest solar radiation, and the highest electricity generation of the year. However, high temperatures may slightly decrease the efficiency of solar panels, as they operate more efficiently at lower temperatures.
3. Autumn:
The duration of sunshine in autumn decreases, solar radiation weakens, and power generation gradually decreases. But autumn weather is usually sunny, and the power generation efficiency of solar panels is still relatively high.
4. Winter:
Winter has the shortest sunshine hours, the weakest solar radiation, and a significant decrease in power generation, possibly only 20% of summer. In addition, the winter sun angle is lower and may be affected by snow cover, further reducing power generation efficiency.
15kw Solar Power System FAQ
A 15kw solar system is typically sufficient to power a medium to large house, as it can generate around 60-75 kWh of electricity per day. This amount of power is more than enough to cover the average household’s daily energy consumption, which is around 30-50 kWh in many regions. However, whether it is enough for your specific home depends on factors such as energy consumption habits, local sunlight conditions, and the efficiency of the solar panels.
A 15kw solar power system can be configured in several ways, such as using 27 pieces of 550-watt panels, 34 pieces of 450-watt panels, or 50 pieces of 300-watt panels. Currently, the 550-watt solar panels are the most commonly used due to their high efficiency. These solar panels are ideal for installations with limited space because they produce more energy per square meter and require fewer panels to achieve the desired power output.
A 15kw solar system typically includes one or more 15kwh batteries, depending on the electricity consumption during nighttime. If the location has high energy usage at night, the number of batteries needs to be increased. For example, a system with a daily energy consumption of around 30kwh would benefit from at least two 15kwh batteries to ensure sufficient power supply.
When selecting an inverter for a 15kw solar system, it should be ensured that its capacity matches the maximum output power of the solar panel. Usually, the rated power of the inverter should be slightly lower than or equal to the total power of the solar system to avoid overload and ensure efficient operation. If the system needs to provide energy storage power during peak hours or at night, a larger capacity inverter may need to be selected.
A 15kw solar system can power multiple air conditioners, depending on their wattage and usage patterns. For example, a typical window AC unit consumes around 1kw to 1.5kw, while a central air conditioning system may require 3kw to 5kw. Therefore, a 15kw solar system can easily support several small AC units or one large central AC system, provided the system is well-configured and has sufficient energy storage for periods of high demand.
