Do Solar Panels Work in Rainy Days?

If you are reading this then obviously you are planning to install solar panels at your personal or professional space and this general doubt has crossed your mind or you are thinking of solar energy applications in rainy areas. Then let me tell you in simple words that yes, Solar Panels do work and generate power even during rains and even in cloudy weather. Let us try and understand how in this article.

How does it function in rains and under clouds?

Technically speaking Solar Panels produce 30 to 40% of their optimum generating capacity under clouds and 10 to 20% amidst heavy rains. Let us see how it works.

Historically speaking the science of producing electricity through solar panels is based on Photovoltaic Effect, discovered by Edmond Becquerel in 1839. It was due to identified through the materials known as Semiconductors which generate electricity when exposed to direct sunlight. The process is simple, first the photovoltaic cells absorb the photons present in the sunlight and then when these rays come in contact with silicon cells the electrons their begin to move generating a flow of electric current. In solar panels a large number of photovoltaic or solar cells are connected in series and parallel to increase the total outcome of the generated power (voltage or current). These solar panels can function both under direct and indirect sunlight. Though their efficiency is maximum under direct sunlight but these solar panels also work under the reflected or partially blocked sunlight as well. Talking about the solar energy future in India,then lying in the tropics has an added advantage as we always have visible light even amongst strongest of the storms as it will always get through clouds and rains.      

What the stats say?

Speaking of statistics then if you install 1kW solar system then in summers it will generate something around 4kWh of energy in 24 hours and under clouds it will be around 1 to 2kWh of electricity and in heavy rains it will be something around 0.5 to 1 kWh of electric energy. These numbers of indicative nature to give a rough idea.

Conclusion

So, to sum it up you need not to worry about electricity generation even in heavy rains or cloudy condition as with solar panels it is an advantage of solar energy utilization that with the slightest of sunlight they will keep on doing their work and all you need to do is install it ones and be rest assured that you will get the best of the results with it. Saving you huge bills and helping the environment at the same time.

Does solar energy really reduce electricity bills?

    Climate change and exhausting conventional sources of energy is nothing new for us. With the several rounds of the United Nations Climate Change Conferences most of the countries have agreed of the adverse effects of the usage of conventional sources of energy . When we talk about the conventional sources of energy.Yes, the first thing striking are the petroleum products but one source of energy that we just can’t survive without and has become an inseparable part of our lives is Electricity. Now with the conventional sources getting close to be exhausted the demand dis not dropping down rather by day it has been on the rise. Due to all this the demand supply gap has been widening like an indefinite cave. And obviously with the demand and supply gap in increase the prices of electricity specially based on the conventional sources of energy were obviously going to rise and hence in the present times what we are noticing in the present times is a surge both of demand of el...

Which is the biggest solar energy company in India?

Solar energy is the most abundant renewable energy source on the planet, not only in India. The need for energy and electricity has increased dramatically in this quickly evolving field of telecommunication and technology. Nevertheless, non-renewable electricity resources are finite, resulting in an increase in need for renewable sources. Tata Solar is one of India's largest and most experienced solar panel manufacturers. Tata Solar manufactures solar panels and offers EPC services. Industrial, corporate, on-grid and off-grid solar plants, and residential are all strong areas for the organization. In the last 20 years, Tata Solar has sold about 1.4 GW of solar panels around the world and installed 1.5 GW of utility-scale and 200 MW of rooftop solar plants in India. Tata Power Solar has completed huge projects in India, including one with a 150 megawatt (MW) project in Anantapur, a 50 megawatt (MW) plant in Kerala, and a 30 megawatt (MW) facility in Odisha. The company earlier w...

Which Indian companies manufacture solar panels?

      Solar Power in India and its utilization have enhanced in many folds in recent times. With the Government of India setting the Sustainable Development Goals with a target of around 22GW of solar power generated electricity, not just the usage but the generation of solar power has increased. For the same both private and public players coming into fore and hence the competition has increased immensely. This is aligned with several policies for promoting the same. Now talking about the industry, there have been reports regarding the solar power manufacturersin India that the Indian Market is about to launch panels of 670W with 21.6% efficiency. This is because of the Mono crystalline technology becoming common, rather a preferred option due to its efficiency, and in the present time there is even a great deal of discussion of hetero junction cell technology achieving the feat of popularity because of its capacity to capture more wavelengths. With international play...
