10kw solar panel systems are popular for their electrical energy production and suitable for homes, cabins, and small businesses. But how many kwh does a 10kw solar panel system produce? This is the most common issue customers asked. Today, we will give a detailed explanation of this issue. Now let’s go.
The main components of the solar panel system
A solar panel system consists of solar panels, solar inverters, energy storage batteries, mounting systems, and other accessories.
How many solar panels do you need for a 10kw solar panel system?
It depends on the power wattage of each solar panel that you choose. For example, if you install a solar panel array with each panel power wattage of 400, then you will need about 25 pieces of solar panels to get the 10kw system.
But if you have more budgets, you can select 550w solar panels in which case you only need 18-20 pieces for the 10kw system.
What is the difference between power KW and energy KWh?
Kw or Kilowatt is a calculation unit of power. 1KW = 1000W.
KWH is a calculation unit of electricity energy. 1KWH is one kilowatt hour. The conversion formula between them is KWh = KW * Hours.
kwh of a 10kw solar system produces
For a 10kw solar energy system, if there are four efficient hours of sunlight, we can use the formula to get the kWh that the system produces. KW*H = KWH: 10*4 = 40 kilowatt hours. But this condition only we set the efficient hours of 4, it will differ as the weather differs, and the places differ. We will discuss the factors that affect the power generation of a solar energy system.
Factors that affect the solar panel system power generation
Weather Conditions
It is sure that the sunny days will generate more power. Sunny days will have longer hours of efficient sunlight for solar systems, while cloudy days, and rainy days not, even though there will be also power generation from solar systems on these cloudy or rainy days. But one thing needs to be clear here, the best time for the better electricity generation of the solar panel systems is not in the summer, they are in the autumn and spring due to the best temperature for the solar panels to generate power is around 25 centigrade.
Geographic Location
Your location is also an important factor. The geographic location determines the power you get from the sun. Take the two places in China as an example. Hainan Province is located in the southernmost of China, The average annual sunshine duration in Hainan Province can reach 1750 to 2650 hours. While Heilongjiang Province is in the northeast of China. The annual sunshine hours in Heilongjiang Province are between 2242 and 2842 hours. Their efficient sunlights depending on where you live lead to different power generation of the solar panel systems.
Solar Panel Tilt and efficiency
The solar panel tilt also plays an important role in solar panel system power generation. Generally, most areas of China are in the middle latitudes. In areas with a latitude of about 30°, the solar panel installation angle of around 30° is more appropriate. In areas with a latitude of about 40°, an installation angle of around 40° is relatively good. However, there are also cases where the installation angle of the panels is set according to the inclination angle of the roof, and this is also acceptable.
For solar panels’ efficiency, as we know, different power of solar panels have different conversion efficiency, which means converting sunlight to DC rate, while solar panels with higher efficiency rate will have more KWH than those with lower efficiency rate.
4. Solar system efficiency
The 10kw solar panel system, as we mentioned above, also includes a solar inverter and an energy storage battery, the inverter is responsible for converting DC generated from the panels into AC, but the inverter conversion rate is not 100%. Most inverters’ efficiency in the market are about 95% to 99%. And for energy batteries, they can store the power from the solar panels for home backup, and electricity usage at night. There will also be energy loss in the charging and discharging process of the energy batteries. As the technology goes on, these efficiencies will surely go up in the future.
Conclusion
So now you know how much power a 10kw solar system produces, it depends on many factors(weather, locations, solar panel tilt, solar panel efficiency, solar inverter efficiency, solar battery efficiency, and so on). However, it’s the best decision for you to make switching to solar energy, this 10kw solar power system will generate the electricity power for your daily needs, and even reduce your electricity bills and reduce carbon emissions for the environment.
