In the view of increasing energy consumption across the globe, it makes sense to take the leap towards solar power.

In fact, recent years have seen a dramatic upsurge in Solar Panel Installations as a way to tap into a more conscious lifestyle. However, it’s a long-term investment, and solar panel efficiency must be considered to get the most bang for your buck.

In real-world conditions, most solar panels guarantee you an energy efficiency of about 16 to 19%. However, determining the energy conversion rate is rarely just limited to the ability of the panels itself.

Chances are some inefficiencies will surface, especially in case you don’t take proper measures to minimize them. In that sense, it pays to get the hang of different factors that could be affecting the panels’ productivity.

So, before you go ahead and invest in the panels with the highest efficiency rating, consider the aspects we detail here as well. Because those ratings are only half of the story.


Factors That Influence Solar Panel Efficiency

Most consumers take the STC ratings as the basis to evaluate the panels’ energy output standards. While it’s important and advisable, real-world performance often deviates from the STC criteria.

So, you may find that a typical solar panel is not able to meet up with its rated capacity. There could be several variables to that including the degradation of the panels’ performance with time.

However, when placed and installed correctly, there’s no reason why your solar panels shouldn’t be able to support your energy requirements for at least the initial 20-25 years.

Thus, understanding more about your Solar System Installation can help you avoid under-performing and sub-par panels for years.


#1. The Relation Between Temperature and Solar Panels

It may sound contrary but higher heat temperatures actually have a negative impact on the panel’s productivity.

In fact, excessive exposure to these very high temperatures can even degrade the quality of the panels before its lifetime. Thus, panels perform better in cold rather than on warmer days.

Panels are usually rated at 25 degrees Celsius. Though, under real conditions, panel temperature can easily reach up to 50 degrees.

Talking about the Solar Panel Types, the output decline in crystalline cells is said to be up to 0.5% for each degree rise in temperature.

However, before you start to panic, know that this is an issue when the temperatures are too high. This usually is the case only during the hottest months. So, a decline in solar panel efficiency shouldn’t be the cause of concern on most days.

Moreover, you have the option to install the panels at slightly elevated angles on the roof for better air circulation and cooling.


#2. Panel Orientation Is Everything

When installing Solar Panels NSW, make sure the panels face the north direction. That’s because this position will help maximize the solar panels’ output.

As a general rule of thumb, locations falling within the northern hemisphere requires the panels to be pointed south.

Whereas, as Australia falls within the southern hemisphere, the Sun will appear to be in the northern part of the sky. Thus, you need to orient the panels such that it faces the north direction.

Furthermore, your home’s topography will also play a major part in it. For instance, roof steepness and the slope will help determine the correct positioning of the panels.

You can also use racks to make modifications in the roof’s pitch in order to angle the panels correctly. Or else solar trackers can be installed to make automatic adjustments in the panel’s orientation.

Ground-mounted solar panels are another option for folks with limited roof space to make any adjustments for solar panel placement.


#3. Changing Weather Conditions and Solar Panel Efficiency

There is a lot of concern circulating around the panels’ resistance to heavy rains and other natural elements. While it’s true that the panels remain fully exposed to the elements on your roof, it shouldn’t cause much damage.


Because most of the quality solar panels are designed to withstand heavy rains and storms for at least 25 years. Some manufacturers even opt for a toughened outer glass surface and a robust back-sheet to provide protection.

Thus, most high-quality, Best Solar Panels will be able to easily withstand the tortures of changing weather conditions. Having said all that, turbulent weather situations may affect the panels’ performance over time.

Some natural forces like rain, snow, dust, and smog year after year may also hinder the amount of sunlight that the panels receive. While the effects are limited, this will reduce the production capacity to some extent.


#4. Pay Heed to Shading Issues

We cannot stress this enough! Shading is one of the major causes you might be witnessing depleting energy production.

Solar Power Solutions need unobstructed sunlight to function properly. Any shade caused due to surrounding trees or any other overhanging objects can be detrimental to the panels’ performance.

Thus, it’s a good idea to trim any leaves or branches that may be getting in the way of direct sunlight. Also, pay attention to other roof obstructions like chimneys and vents.

As a matter of fact, installing micro inverters is often touted as an efficient way to minimize the effect of shading on the panels. In this case, only the production of the shaded panels will suffer without affecting the whole system setup.

Though, it requires additional investments and not everybody can afford to install micro-inverters. Thus, the easy way out is to keep the panels in an unshaded state.


#5. Regular Maintenance and Upkeep

A Solar System NSW rarely requires heavy upkeep and maintenance measures. Most people with solar panels just take necessary cleaning precautions to keep them in good condition.

Still, it pays to keep the electrical connections in check so as to maintain the solar panels’ energy output.

Moreover, any roof maintenance projects should be carried out before Going Solar. Undertaking any such works after the actual installation is giving an invitation to additional costs. Plus, it’s rather impractical.

Keep an eye out for any cracks in the solar panels, though. These cracks can provide room for condensation to develop within the panel and can significantly affect energy production. Also, in this case, it’s likely a good call to get in touch with a solar installer for the right solution.

Last but not the least, regular cleaning is at the core of every panel’s maintenance. Once installed, dust can easily accumulate over the panels. Thus, keeping them clean of daily pollution and debris will pay off in terms of solar panel efficiency.


A Robust Performance Warranty Protects Your Initial Solar Investment

Well, your solar panels will degrade with time and there’s no denying that. However, investing in a Solar Panel Solution that comes with a performance warranty is a much more prudent step in the long run.

Most top-rated manufacturers offer 25 years of performance warranty on their panels.

Typically, you can expect at least 90% production at 10 years and 80% by the end of 25 years.

This means your solar panels should not lose more than 10-20% of their rated output capacity over the first 25 years.

Higher warranties are usually a good indicator of the panels’ performance and reliability in the long haul. In case the power output does degrade before the specified warranty, the manufacturers will either repair or replace the panels.

Another parameter to ensure optimal power output is to invest in mono-crystalline panels. These tend to have better solar panel efficiency. Thus, offering good performance standards from the get-go.

Needless to say, a professionally installed solar panels system is more than likely to last for years.

We can help mitigate most of these efficiency risk factors through our industry-leading solar products and solar maintenance from certified professionals.
