How many solar panels will you need?
The largest size in residential solar panels that we install at Amrut Solar is the 7kW solar panel system.
This system harnesses the sunlight it gets and then processes it to make 6930 watts of electricity.
For this amount of energy, and keeping in mind that an average solar panel, irrespective of brand, produces a minimum of 330 watts, you would need to install 21-24 solar panels as part of your residential solar system.
How much electricity will a 7kW solar system generate?
The 7kw solar system is a big player, with a rise in demand for it due to the increasing sizes of homes in Australia, and people’s general disposition shifting towards sustainability.
With 21 solar panels needing to be installed, and an average of 330 watts of energy produced by one panel, you would be producing 6930 watts of power.
It must be kept in mind, though, that the production of solar energy is not constant, as one day there may be more sunlight than another, and some days the sunlight would hit the panels differently.
You may also have to factor in some variables such as natural shade on your panels, etc. that could redefine the output of your solar system.
What are the benefits of 7kW solar energy system panels?
A 7kw solar energy system is one of the most economical ways to power your home, and make savings at the same time.
Installation costs of this kind of system are paid off within the first year or so of installation in the form of saved electricity costs.
This kind of large solar system is usually hooked to the electricity grid. This means that not only will you be able to access electricity if your solar panels do not produce enough to power your large residential property, but if your solar system produces excess energy, it will get fed back into the line and redirected.
This redirection would cause the electric company to have to pay you a certain amount per watt transferred in the form of energy credit.
How much space do we need for a 7kW solar system?
For an average 7kW solar system in Melbourne, you would require at least 50 square meters of roofing to lay the panels.
This system is meant for larger residences and so would require a bigger roofing space and space for an inverter
Keep in mind that each panel is sized at 1756×1039×30mm (69.07×40.97×1.18 inch).
