How Many Solar Panels for 5-Kilowatt Load?

To determine how many solar panels are needed to power a 5-kilowatt load, we need to consider several factors, such as the efficiency of the solar panels, location, sun hours, and battery storage (if required). Let's assume a few standard values for the calculation:

  • Solar panel efficiency: 15-20%                                                                                                                               
  • Average sun hours per day: 5 hours (this varies depending on the location and season)
  • Battery storage: Not considered for simplicity (you may need additional panels to charge the batteries if you require 24/7 power supply)

To calculate the total wattage of solar panels required, divide the load (5 kilowatts) by the average sun hours: 

  • Total Solar Panel Wattage = (Load in kilowatts) / (Average sun hours per day) 
  • Total Solar Panel Wattage = 5 kW / 5 hours ≈ 1 kW (± energy loss)

Here the solution is, you need approx. 3 solar panel of 440 watt each is sufficient for 5-kilowatt load. This solar panel is most powerful and one of the advanced technology products it has Super High-efficiency Solar PV Modules that is made of Pure Mono Perc Cell technology and the efficiency of this panel is 20% to 25% higher than the others, also this is capable to work in cloudy weather conditions or bad weather conditions. This panel is highly recommended for residential rooftop installations as it can generate 30-50% more power in a limited space compared to conventional Poly Solar Panels. The frame is exceptionally sturdy with middle support, ensuring durability and longevity.


Please note that this is an approximate estimation, and the actual number of solar panels required might vary based on your specific location, weather conditions, and other factors. Additionally, it's essential to consider any other factors such as shading, panel degradation over time, and system losses. It's recommended to consult with a solar panel installation professional to get a more accurate assessment for your specific needs.
