Solar Panel Degradation | New Software

Solar panel degradation is a big issue, and one of the problems with it is that it can be a bit nebulous to measure, especially if you’re off-site. An Indian university may have some answers with regards to measuring this in a cost and time effective method.

Solar Panel Degradation | Alternatives to on-site inspection.

Parveen Bhola is a research scholar at India’s Thapar Institute of Engineering and Technology. Alongside Saurabh Bhardwaj, an associate professor at Thapar, the pair have developed and optimised statistical and machine learning-based alternatives to enable real-time on or off-site inspection of solar panels to measure the solar panel degradation. This is achieved throughout the usage of clustering-based computation – utilising historical meteorological data to compete performance ratios and solar panel degradation. Factors such as temperature, pressure, wind speed, solar power created, sunshine hours, humidity and historical performance are all utilised to come up with a measurement of the panels’ effectiveness. 

“The majority of the techniques available calculate the degradation of PV (photovoltaic) systems by physical inspection on site. This process is time-consuming, costly, and cannot be used for the real-time analysis of degradation,” Bhola said in a quote posted on TechXplore. “The proposed model estimates the degradation in terms of performance ratio in real time.”

As solar panel technology increases, it’s important that our tools for troubleshooting and optimising their output be improved commensurately; this is a great step for all solar system holders, but especially those in rural areas where having someone come on site is cost and time prohibitive. With this new technique it’s likely that troubleshooting will be more efficient and perhaps even point out problems before they occur.

Solar Cell Windows for sale in Asia

Some amazing technology out of Asia pioneered by Asahi Glass has windows with solar cells embedded in them being offered to the global market. These solar cell windows will be marketed to developers worldwide, with a focus on Australia and Oceania.

Asahi Glass Solar Cell Windows

This technology isn’t new (it has been offered to the Japanese market since 2000), but is experiencing a resurgence as Asahi are preparing the product for export. The windows will be offered for developers to implement as part of construction packages in order to help meet Asia’s rapidly growing renewable power needs.

The solar cell windows can generate 2-4 watt hours per square 15.6cm per side, depending on design. The plan is to sell Sunjoule to construction projects in Australia and the rest of Oceania – they’ve already installed in Cambodia, Singapore, and Hong Kong where they have set up shop to target European and US property developers who want to add unique and eco-friendly functionality to their building designs. They also plan to start producing these energy-conserving solar cell windows/glass in 2018 in Indonesia, according to Nikkei.com. Here’s an article from Inhabitat talking about the ‘nanosolar‘ thin and flexible solar cell coating which is utilised in the panels.

Asahi are a global glass manufacturing company who offer myriad products such as heated windshields and 3d curved cover glass for car mounted displays. They turned over $12.8 billion USD in the 2013 financial year and have 51,500 consolidated employees so they are a major player in the industry. According to Wikipedia they are one of the largest flat glass producing companies in the world.

Asahi India Glass Ltd. (AIS) – who are an Indian affiliate of the company – also offer a mobile app called ‘AIS – World Of Glass’ for end users and partners to gain a deeper insight and experience into their portfolio of glass offerings. Click here for iOS and here for Android if you’d like to give it a try!  We’ll be interested to see how much the solar panel technology increases over the coming months and years and how Asahi are able to improve and enhance their offering – solar cell windows are a great innovation and it’ll be interesting to see how quickly the technology is picked up worldwide and how competitors react to this product.
