Solar panels are a great example of the revolutionary technological advancement of the era. It recycles one form of energy into another form which can be utilized later. They are in trend a lot lately and used by everyone around the globe with distinctive purposes like residential use, solar farming, etc.
The process of converting sunlight into electricity is very fascinating but it also depends on no. of factors related to the features of the solar panel as to how much energy it can or will produce. Factors like size and type of the panel, the efficiency of the solar cells and environmental factors like the amount of sunlight your rooftop solar panel is exposed to are some of the key factors.
How does a solar panel produce electricity?
A solar panel generates electricity using the Photovoltaic cells which are incubated in it; these cells get triggered by photons particles that are present in sunlight and generate electrical energy which is then transmitted into the power grid for further use.
This whole process is called the Photovoltaic process and is believed to be a breakthrough in the field of technology which still keeps on improving through the years to enhance the efficiency and production capabilities of it.
The best solar power system in Brisbane are always equipped with high quality of PV cells that are efficient and can enhance the productivity by up to 15-20%, such PV cells also have long-life expectancy because of which they can produce electricity for a longer period of time.
Why does the size of solar panel matters?
The main component of the solar power system is the panel under which solar cells are arranged and due to this factor, the amount of electricity generated by a solar panel is directly proportional to the size of the panel. If the panel is large in size it will have more space to fit solar cells and more solar cells will absorb more sunlight and will tend to produce more power than a smaller one. Therefore, the size of the rooftop solar panel will directly affect the production capacity of the solar power system.
But it is not always recommended to get a full-size panel because it is successful only if your geographical conditions are favorable and if you get immense sunlight on your roof. Due to such reasons, there are multiple sizes that are available with solar panel installers and suppliers. Most commonly used sizes for residential properties are:
- 5×3 feet, which have 60 solar cells
- 7×3 feet, which have 72 solar cells
Moreover, if you’re looking for a commercial solar panel, you can get much bigger sizes than this, so always ask your solar panel installer for multiple size configurations.
How much energy does one Solar Panel produce?
The amount of energy a solar panel generates depends on its configuration and environmental factor at your location. So typically a decent property consumes around 850-900 kWh of electricity monthly and a 5 kW solar panel can produce approximately 400 to 900 kWh of electricity under most favorable conditions, which means that it can provide 100% of your monthly electricity needs. This stat is for one solar panel which occupies around 400 sq. feet of space.
Now with a bigger capacity like 6.6 KW solar panel you can derive about 1000 to 1200 kWh of electricity monthly but the panel size will also be bigger in this and it will take more space so this capacity of rooftop solar panel in Brisbane is suitable for large properties that have ample space on roof for such a large setup. One little thing that is important in power generation is the type of solar panel you get, there are many options nowadays with the development of solar technology but two of them are the main types which are:
- Monocrystalline– These have more efficient PV cells which can provide efficiency of up to 20% and are known as the most efficient of all types, such panels are black in color and are economically costlier among all.
- Polycrystalline- Polycrystalline solar panels are blue in color and can provide efficiency of about 15-18%, these panels have double-cut PV cells which are very efficient, it is also cheaper as compared to monocrystalline panels.
How efficient are solar panels?
With the progressive advancement in solar technology, it’s efficiency is also increasing day by day. Back in the 60s and 70s, solar panels were limited to a 6-7% efficiency rate but with the production of new types of PV cells, efficiency kept on increasing and today a solar panel can derive about 20% or more efficiency rate. Sunlight is also an important factor in deciding the efficiency rate because if the cells do not get adequate sunlight then they will absorb less and ultimately will produce less electricity.
Along with the efficiency of the solar cell, it’s life expectancy is also very crucial, because solar cells tend to lose its power with time being, so always ask your solar panel installer in Brisbane for high life expectancy solar panels which have robust quality of solar cells which should also have a fixed rate of efficiency for a long term period say for 5-7 years, so you can get consistent productivity for a longer period of time till it starts to lose its power.
How much can you save with Solar?
According to the studies and information mentioned above, one can save a very good amount of money with the help of solar. With the rising rates of electricity, your electricity bill will only increase no matter what your consumption is. The solar power system in Brisbane can help you to get rid of expensive electrical bills, best solar power system which is laced with high specs configuration can fulfill your average monthly consumption of electricity, which means you can generate free electricity for yourself.
Apart from fulfilling your own need, if there is excess power which is generated by your solar power system, it can be fed to the supplier’s power grid for which the supplier pays you in return as per the payback rate of your area, which means apart from saving, you’re also earning money from your solar panel. Therefore, a solar power system is more than just a technological breakthrough but it is also an economical device that can save a lot of money.
