Solar panels have become one of the excellent ways of reducing the consumption of one of the non-renewable resources, which is electricity to a certain level. First, it was just employed for the supply of hot water, and as the technology improved, solar panels were employed in the conversion of solar energy into electrical energy.
If you are planning to get such solar panels installed in your homes, then the first thing that you should understand is the actual supply of electrical energy each solar panel can produce. Once you understand about the actual amount of energy that each solar panel can produce, you can then decide about the number of panels that you should get installed at your home.
The actual amount of solar energy that a solar panel can absorb from the atmosphere will be decided based on three main things. They are,
- Size of the solar panels
- Severity of the sun rays that are falling on the solar panel like during morning, afternoon, evenings, etc
- The working efficiency of the solar cells that are installed inside each solar panel
Solar Panel Output – What is it
Just the way solar panels differ in their dimensions, they are even different when it comes to absorbing sunrays from the atmosphere. Not all of them are efficient enough to absorb sufficient amount of solar energy, which can be converted into electrical energy for the whole house. Hence, first you should know about the amount of output of each solar panel, before planning to get them installed in your home.
Solar panels that are employed in house installations are also known as domestic systems. Here is a brief idea about the domestic solar panel output.
- The overall supply of electrical energy that you can expect from the domestic solar panel will be around 1 kilowatt and might range till 5 kilowatt.
- When you estimate the overall supply of domestic solar panels on yearly basis, then it will be around 850kW units. If you install the domestic systems that can produce 2kW energy, then the yearly supply will be around 1700kW, and if it is 5kW system, then the yearly supply will be around 4,500kW.
Surveys have shed light on the fact that a house with 3BHK facility will require minimum of 3000kW energy supply per annum. The installation of solar panels with the capacity to produce 3kW electricity supply is best suited option for such 3BHK houses.
For smaller households, the suggested solar panel type will be the domestic systems with 4kW capacity. By installing them, the occupants will have enough supply of electricity to run washing machine, fridge, oven, kettles, etc, 365 days a year. When estimated, it was understood that the domestic system with 4kW capacity will provide around 3,400kWh energy supply.
If you are still in confusion while making the right decision when it comes to solar panels, then all you have to do is find the electricity bill from previous month and multiply the overall usage of electricity 12 times. By doing so, you can understand the requirement of electricity supply of your house per annum. You can find the right solar panel installation service and hire them by visiting their website.
