Desert Knowledge Australia Solar Centre Proven Solar Panels

What is Desert Knowledge Australia?

Desert Knowl­edge Aus­tralia (DKA) is a not-for-prof­it statu­to­ry cor­po­ra­tion of the North­ern Ter­ri­to­ry, estab­lished in 2003 to encour­age learn­ing, socioe­co­nom­ic devel­op­ment, research, and envi­ron­men­tal sus­tain­abil­i­ty in Cen­tral Aus­tralia. DKA is com­mit­ted to devel­op­ing oppor­tu­ni­ties to build a stronger and more con­nect­ed desert and remote Australia.

What is the DKA Solar Centre?

The Solar Centre is one of three active solar-resources projects that is operated by Desert Knowledge Australia in the Northern Territory. The public-use and open access knowledge that these projects provide enables live and historical insight of meteorological, performance and irradiation data.

The DKA Solar Centre is of particular interest to WINAICO and our partners as it is a live demonstration of module performance in extreme climatic conditions. The site consists of (currently) 38 separate solar installations by different solar module manufacturers installed at various times of the last 12 years.

The reason for this introduction to this project is because WINAICO is one of these Installation Sites. Installation number 34 is a WINAICO solar emplacement established in 2012 a few weeks after our company began operation in Australia. The DKA Solar Centre was the perfect opportunity to demonstrate the performance of our modules and help develop trust with the early solar market.

The emerging solar industry in Australia was an optimal time for WINAICO to launch their brand. As a high quality manufacturer with international support, the installation at the Desert Knowledge Solar Center was the final support needed to demonstrate WINAICO's quality. Installation Site 34 consists of 22 modules that generate almost 5.3 kWs of power. The 240 Watt polycrystalline modules were market leading products in power and durability during this period. Now WINAICO has 330 Watt Monocrystalline versions in the same technical format.

Monitoring Performance since 2012

Solar modules will degrade over their technical lifespans due to natural chemical reactions within the silicon cells. Limiting the amount of performance degradation over a modules lifetime is a longevity consideration that sits on the minds of only high quality solar manufacturers. The Alice Springs environment can generate high winds, excessive dust, extreme heat and cold all within the same day. The 8 years of installation can help identify the performance of the WINAICO modules and track their degradation in this inhospitable Australian environment.

So the next question is how are they currently doing?

Comparison of Solar Installations and the Year they were installed.
Comparison of Solar Installations and the Year they were installed.

Here is a graph generated of a daily solar power generation from the DKA Solar Center site. The data series are different solar installations and the year they were installed. The vertical axis provides a standardized power to installation power metric that enables multiple sites to be compared regardless of the size of the solar system.

The 2012 WINAICO Installation outperforms the older systems installed in previous years. As explained previously, degradation is a process experienced by all solar modules and provides an explanation for the higher power of the WINAICO system. However, the greater power ratio of the WINAICO installation compared to the more recently established systems is not an expected occurrence.

The graph demonstrates that systems installed in 2014, 2016 and 2017 have degraded faster and performing worse than the older WINAICO system. This is an unexpected case as these modules are using more modern silicon and manufacturing procedures compared to our 2012 model. The drop in performance of modern solar modules suggests that they are experiencing more advanced degrading, becoming less efficient at faster rates than the WINAICO installation.

This should not be a concern for those installations, as they remain within their power warranty claims. This comparison is to highlight the difference of WINAICO's manufacturing quality several years after installation to several other market options.

Annual Degredation of Solar Modules

Manufacturers guarantee a certain level of performance through a mechanism known as a power warranty. It states that solar modules will be always capable of producing a minimum amount of power in certain environmental conditions known as Standard Testing Conditions. The minimum value decreases each year after installation to reflect the slow drop in power.

DKA Solar Centre Comparison
WINAICO Energy Production from the DKA Solar Centre in 2013, 2019 and 2020

The image above illustrates the average daily energy generated by the WINAICO Installation at the Desert Knowledge Australia Solar Centre. To provide an a more clear comparison, the first full year (2013), last complete year (2019) and this year (2020) were included in the graph.

While the performance of our modules are dependent on the weather, the graph shows very consistent levels of energy production in recent years to the first year after installation. As of writing this blog post, 2020 has completed 9 full months of energy production that we can use for comparison. The 2020 performance generated higher average monthly energy in 5 of those 9 months.

This is a remarkable indicator of performance, suggesting only small limits of degradation have affected these modules and extended performance of the WINAICO system 7 years after installation.

Additionally, 2019 produced 8 months of higher average energy production than the 2013 year. This further reinforces the ides that the WINAICO system is generating energy at consistently high volumes.

Why Choose WINAICO?

Two critical elements of focus for WINAICO is longevity and performance. The Desert Knowledge Solar Centre is a prime example of how our modules are expected to operate in tough and inhospitable environments.

With the assistance of our Trusted Partners Program, we can rest easy knowing WINAICO Modules are in the hands of installers that will take the extra time to ensure you have the best solar system for your home or business.  When you purchase a WINAICO System, you have both the power and support to help become energy independent.
