With the solar panel installation government scheme, more and more homeowners are making the sustainable decision to go solar. This decision precedes a vital question about how much energy the panels produce. To answer this, we have outlined a simple calculation which every homeowner can use to calculate the energy produced daily and monthly.

How much energy does a solar panel produce?

Considering your Roof Top Solar Hybrid panels receive direct sunlight, here are some average energy metrics of your panels:

  • A newly installed solar panel can produce 370-415 watts per hour of energy.
  • Residential solar panel systems generally have a capacity between 1 kW and 4 kW.

Here is a rough idea to calculate the average energy generated through solar installation for home:

  1. Calculate the solar panel output per day
    Use this formula to calculate the amount of energy generated in kilowatt hours (kWh)
    Size of one solar panel (in square metres) x 1,000 (Let’s say Y)
    Now, Y x Efficiency of one solar panel (percentage as a decimal, say Z)
    Next, Z x Number of sun hours in your area each day
    Divide by 1,000 (say X)
  2. Find out solar panel output per month
    Multiply X with 30 to calculate the solar panel output for a month.
  3. Solar panel output per square metre
    The most common panel used by domestic solar companies is 4 kW. This consists of 16 panels of 1.6 square metres (m2) and produces roughly 265 watts (W) of power (in ideal conditions). Now, find out the output per square metre using this formula:

Number of panels x Capacity of solar panel system
Capacity/(divided by) Total size of the system (number of panels x size of one panel)

All the above calculations are done considering the ideal conditions and the panels working optimally. However, several factors govern the efficiency of the panels:

  • Panel material
    Solar panels are made of three materials: monocrystalline, polycrystalline, and thin film. Monocrystallines use higher-grade silicon, which is the most efficient, followed by polycrystalline and thin film.
  • Placement & orientation
    The Rooftop Solar Panel for Home must be tilted and angled in such a way that it can receive the maximum sunlight. As the sun is higher in summer than in winter, we advise you to modify the panel angle twice yearly for best results. Also, the roof should be free from shade and obstacles that might hamper sunlight reception.

At KCP Solar, our team ensures you get the best solar installation for home for maximum energy output. Let us help you get clean energy for the rest of your life that too in budget.
