Solar Energy- Why Go Solar? Advice for Residents Wanting To Go Solar

It is time to realize that the future is here for your home, and it is here to stay. If you have ever considered putting a solar solution on your home’s rooftop, the best time to turn this thought into action is now. There exists a golden opportunity today with all that is happening in the energy industry across India as trends from 2018–19 show a dramatic increase in the tariff rates for electricity across all slabs in India, increase in electricity consumption and parallel demand; non-renewables across the world do not have much to offer for long, and more than anything, the Indian government has been pushing solar energy very ambitiously in recent times. In fact, the Government of India has brought upon policy changes in this domain as well as subsidy provision for solar rooftops. Nonetheless, this has led to new plants being commissioned on a weekly basis.

Geographically, India is, in fact, the ideal country to embrace solar power in its entirety. The country’s Goldilocks location on the world map means an average of 300 sunny days every year, which is ideal for solar power generation. This fits in perfectly, as according to the Ministry of New and Renewable Energy (MNRE), 1 kW of solar power produces an average of 1500 units per year in India, making Indian households a goldmine for solar investment.

Moreover, one needs to understand what a brilliant investment going solar has proved itself to become, helping home-owners make money from sun by adopting on-grid solar rooftop systems that guarantee a return on investment in less than 4 years. Not only does the onset of on-grid rooftop technology brings with it monetary supremacy over other means, but it also brings about the feasibility for residentials who choose to look for a more pragmatic route. Unlike traditional ways, the applicability of solar on your pre-existing rooftop and the absence of need for obtaining more land for the installation of the same makes  this a much more simpler option than other means.

You cannot ignore the maintainability and safety factor either. Solar panels ideally generate at least 80 per cent of peak capacity consistently for over 25 years and the maintenance cost for said panels accounts to about 5 per cent of the total amount invested. Couple that with the fact that at the end of the financial year, you are going to earn significant interest no matter what, nothing even comes close as financially sound an option as on-grid solar.

What Are Some Common Myths?

 There are a lot of myths and misconceptions in the minds of homeowners regarding rooftop solar systems. One of the biggest misconceptions is that a solar system is not cost-effective or economically viable for residential use. On the contrary, households that have invested in going solar have seen significant decrements in their monthly bills, some even boiling the bills down to zero. The power of bidirectional net-metering allows for this to happen as it enables you to send the excess units generated by your solar system back to the grid at the same rate at which you once incurred your bill. People tend to have suspicions on whether solar energy can actually power their ACs, geysers, and other heavy appliances, as well. As a matter of fact, solar energy is not only capable of powering the aforementioned load-heavy household appliances but also reduce their consumption  costs drastically.

 Another myth surrounding the household space revolves around the misconception that solar systems don’t generate electricity during cloudy times of day, especially during the winter months. In reality, your panels will generate electricity if it is day time because it is not the heat that brings the initiation for electricity, it is the high-frequency light from the sun. Solar panel systems are based on the concept of photovoltaic technology which basically means, as long as there is light in the sky, you can realistically expect up to 75 per cent of peak generation capacity from your solar PV system. The real point here is that the production never goes down to zero, period.

Some homeowners mistakenly believe that installing a solar system might damage their roofs or render it unusable for any other purposes. In truth, solar panels are not directly attached to the roof but are mounted on top of it. These elevated panels actually protect the portion that they cover and provide shade to rest of the terrace. This leaves the roof for other utilitarian purposes such as drying of clothes and the like.

The sheer popularity of such misinformation indicates distrust in the credibility of source(s), and that is why there is a dire need for the companies in this sector to take it upon themselves in helping educate the target audience in solar so that they can take a  mindful decision.

Things to Keep in Mind When Going Solar

From a customer standpoint, you first need to consider the finances and follow that up with the practical feasibility of it all. For guidance, 1 kW solar produces about 1500–1600 units of electricity per year. So, if your average monthly electricity bill is more than INR 2000, it makes absolute sense to install solar as it can help in 100 per cent reduction of electricity bills. But it falls under the umbrella condition that you have the roof rights and physical access to the same. From a technical provider standpoint, the location and area of your rooftop is the first thing to check for solar panel installation. In fact, 1 kW solar rooftop systems require approximately 100 sq. ft of rooftop area and this might pose a challenge on tight-space installations, so keep this as a prime consideration. The second most important thing to consider is the orientation of the solar panels. Since India lies in the Northern hemisphere and the sun directionally moves from east to west with respect to the southern portion of the sky, your panels should be placed in the direction of true south to ensure optimum performance. This should be followed by shadow analysis which is imperative to avoid loss of incident solar radiation on solar panels due to obstructions such as buildings, tall trees, etc., surrounding the rooftop.

In our company’s case, all the hard work of deconstructing and analysing the above-mentioned factors is done by our ZunRoof App, which is based on foundations of cutting-edge technologies like Data Analytics, Image Processing, Artificial Intelligence, and Virtual Reality, that guide our optimization process to give extremely accurate estimations for all factors. So, make sure you choose the right company for going solar.

Nominations open for CSP Today India awards 2013

The inaugural CSP Today India awards ceremony takes place on March 12, and CSP developers, EPCs, suppliers and technology providers can now be nominated.

CSP has made tremendous progress since the announcement of the Jawaharlal Nehru National Solar Mission in 2010. With Phase I projects now drawing closer to completion, the first milestone in India’s CSP learning curve is drawing closer. CSP Today has chosen the next CSP Today India conference (12-13 March, New Delhi) as the time for the industry to reflect upon its progress and celebrate its first achievements.

At the awards ceremony, industry leaders will be recognized for their achievements in one of 4 categories: CSP India Developer Award, CSP India Engineering Performance Award, CSP India Technology and Supplier Award, and the prestigious CSP India Personality of the Year.

Matt Carr, Global Events Director at CSP Today, said at the opening of nominations that “CSP Today are excited to launch these esteemed awards, which will enhance the reputation of their recipients. I am particularly excited to launch the CSP India Personality of the Year award, a distinguished honor for the industry figure deemed worthy by their peers.”
