7 Key Factors To Determine Solar Panel Efficiency.

Switching to solar is not at all a new phenomenon in Australia. Every day more and more Aussies are shifting to solar energy from traditional energy sources. If you don’t know, you must be living under the rock!

Solar panels in Queensland have seen a tremendous rise over the last years and today, if we talk about the capital city, more than 30% of homes have solar power systems in Brisbane.


Solar power efficiency is a vital issue to be taken into the account before you power up your homes with solar energy. A solar panel is basically consisted of solar cells, usually the size of 6 *10, and exposed to solar energy.

Simply put, the efficiency of a solar panel is a conversion rate as to how much solar energy, it converts into electricity. Generally, it is around 11-15%. The highest performing rate is 20% in the market today. However, most people get sufficient electricity supply with around 11-15% efficiency.

The quality of a solar panel is assessed by a whole host of variables. Solar power efficiency is one of the aspects to consider along with the price and the availability of roof space.

Let’s find out key factors that determine the efficiency of solar panels.


1. The type of panels.

The manufacturing material is significant to assess the quality of solar panel efficiency. There are primarily three types of solar panels:

Monocrystalline solar panels

Monocrystalline is the highest purity silicon; hence, the solar panels made up of Monocrystalline are the most efficient.

Furthermore, it needs less area to compare to other panels. It converts almost a quarter of solar energy into power with massive 25.6% efficiency. No wonder, they are the best option in the market!


Polycrystalline solar panels

Not as efficient as Monocrystalline solar panels, it still brings in around 20% efficiency and still improving! The efficiency rate of this panel is likely to grow in the future.

The real differentiator is an affordable price. It is an ideal choice for anyone cannot afford the Monocrystalline solar panel, making it the most popular panels among customers.


Thin-film solar panels

They are so far the most downgraded option. The average efficiency output is just 11%. Not only but also it requires a large roof space to function.

Needless to say, Thin-film solar panels are the most affordable option owing to its poor performance.


2. Shade

This sounds obvious but having a solar panel installed in an area free of shade helps you achieve more efficiency output.

It varies from home to home and location to location. It is a subjective matter. If you are living in neighbourhood where the sunlight is blocked or somehow not reaching the solar system, it will impact the solar panel efficiency considerably.

It usually happens due to vegetation, surrounding buildings or hills that don’t allow the solar rays to pass through. However, Micro-inventors can be extremely useful to rectify shading issues.


3. Orientation

Besides the location, the position too is equally important. It should ideally be angled to expose to maximum sunlight. It means Solar panels in Queensland should be facing towards the north.

Take care of this matter while setting up the solar panel and make sure the pitch of the roof is allowing maximum solar energy to consume.


4. Life span

Nothing lasts forever! The efficiency gradually drops down. The average life span of a solar panel is around 20 years and it is assumed to reduce 0.5% efficiency every year.


5. Inverter efficiency

Inverters turn variable current from the solar power into alternating current and stores into the grid. It is a primary feature of a solar panel.

It is recommended that you use standard inverters to maximize the solar panel efficiency.


6. Maintenance

Although solar panel demands little to no maintenance, it still contributes to the efficiency of your solar panel. Keeping solar systems neat and clean will add up to the performance.

It is open and exposed to the external environment all the time. Naturally, there will be dust and dirt that you need to wipe out once a month at least.


7. Temperature

Solar power systems in Queensland, however, are less prone to affect with it. The province has a subtropical climate, usually warm and hot throughout the year.

Lower temperature decreases solar panel efficiency. Positioning solar panels to a point where they receive sufficient air and sunlight will help keep them warm.


Conclusion

Besides the location, the position too is equally important. It should ideally be angled to expose to maximum sunlight. It means Solar panels in Queensland should be facing towards the north.

Take care of this matter while setting up the solar panel and make sure the pitch of the roof is allowing maximum solar energy to consume.


Consider these important factors before choosing solar power to run your homes or else it will not serve the purpose.
