Predicting photovoltaic losses in Indian solar rooftop using IoT

Solar on the rise…with a catch!

Solar power plants are on the rise as the better and more reliable way to boost the Indian renewable energy industry. Although it isn’t the latest entry, solar power is arguably the one with major untapped potential and rapid scalability. Solar Energy generation is almost as renowned for its lower regular maintenance as having their performance contingent on the surroundings.

Being an open energy system, solar generation is intermittent and highly dependent on having suitable weather. Incidentally,there are also intrinsic limitations governed by their material physics. Since any decrease in generation can result in considerable financial drawbacks, it is important to predict the possible generation. Energy estimation is only possible when we are able to effectively model the system taking into account its various parameters as well as losses.

The most important parameter influencing generation is the incident irradiation. This dictates the upper bound on the energy that can be harnessed. Apart from that, photovoltaic losses play a crucial role in benchmarking the maximum generation possible.

These losses depend on a plethora of factors including cloud cover, module operating temperature, ambient temperature, particulate deposition on modules and sensors, grid unavailability, etc.
