How Does Solar Technology Actually Work?

Solar technology works on the simple principle of Photovoltaic effect. Sunlight contains photons. When they fall on a semiconductor like Silicon, the solar radiation frees electrons of the semiconductor. This creates an electric field which in turn produces electricity. Light's use for electricity was first applied when Bell Labs invented the Photovoltaic (PV) cell in 1954.

Solar technology uses sunlight (solar) and heat (thermal) energies of the Sun. We will discuss the mechanism behind each.

The Urgency of Green Buildings

It's a prettier world with lesser buildings. At least, the birds will find more trees to land on them. India's urban population stands at 493 million today and an additional 300 million are expected to arrive by 2050. This means buildings and other infrastructure will continue to expand.

Last year, the country was filled with 40.6 billion tonnes of carbon. As this creates rainfall disturbances and long periods of heat waves, India may see large rural-to-urban migrations as the agriculture sector plummets. In 2022, roughly 1.8 million hectares of soil were affected.

How New York Became Sustainable

A category I hurricane hit New York in 2012. As it lashed many Caribbean countries and New Jersey and New York states in the U.S., it was renamed to a Superstorm, surpassing even category I storms.

When it hit New York, Subway lines flooded, suburbs drowned, fires erupted, power outages occurred city-wide, road tunnels entering Manhattan got waterlogged, and 53 people died. The state underwent a loss of 19 billion USD. It was a warning; a disaster could end a state balancing on the edge of an ocean. Since then, the state has focussed on redeveloping safer water-front housing, enacting policies, reducing carbon emissions, and planning green building projects.

How to maintain my home's solar rooftop plant?

Any rooftop solar PV system must include operations and maintenance (O&M). Even though a rooftop solar PV plant requires little regular maintenance, it is crucial to make sure the system is kept up well and is operating at peak efficiency.

Guide to Reading Solar Proposals

How to Read a Solar Proposal

A solar proposal is a document that outlines the details of a proposed solar energy project. It is typically prepared by a solar energy contractor or provider and is presented to a homeowner, business owner, or other potential customer. The proposal includes information about the size and design of the solar panel system, the estimated energy production and financial savings, the equipment to be used, warranty information, cost breakdown, payment terms, installation timeline, and maintenance requirements.

Designing A Sustainable Future

The country is like any other living organism. It contains its own environment and ecosystems. Now and then, like any other organism, the country gets damaged, overused, or even erodes with time. To make the country last longer, we try to repair it. Designing a sustainable future does just that. It's medicine, an antidote to improve the well-being of the country and the tiny cells (us) who depend on it. But to understand how to medicate the country, we should understand its symptoms first.

What would it cost to set up a solar power system at home?

The price of installing solar panels varies depending on the region, style of rooftop, and kind of panels utilized. Although more expensive up front, premium solar panels with high efficiency and beneficial warranties provide more potential for long-term savings such as reduced cost of electricity bills, carbon footprint, and annual energy expenditure.

Zero Waste Movement

Zero waste is an ethos and an end goal that seeks to reduce waste and conserve resources through responsible production, consumption, reuse, and recovery. It can have a number of benefits, such as reducing the impact of waste on the environment, conserving natural resources, and reducing greenhouse gas emissions. India is working towards zero waste through municipal solid waste management, plastic waste management, community-based initiatives, government initiatives, and business initiatives.

Why companies should follow sustainable practices?

A good part of the earth is disappearing in service of large industries. There is a continuous loss of water, soil, and crop. Climate change causes natural calamities, barren land, and crop growth. This also leads to civil strife and obstructs companies from their suppliers worldwide.

In 2004, Coca-Cola shut down its industries in India due to water shortage.  In 2011, floods in Thailand drowned over 160 textile industries. Nearly 25% of the textile industry of the country was wiped out. Due to water distribution issues in Peru, 21 billion USD in oil mining projects have been suspended. Companies'  decisions cause environmental damage. Like domino pieces, society and the economy take the next hit.

Adoption of Sustainable Living in India

In India, sustainable development consists of a diverse range of policy interventions in the social, clean technology (clean energy, clean water, and sustainable agriculture), and human resources sectors. India is also expected to start replanting its national income accounting, making natural capital wealth depletion a fundamental component in its computation of GDP.

Despite extensive deforestation, commercialization of green lands, and open-air emission of noxious substances, there are endeavors by rare people that practice sustainable living. A major portion of the country's population still lives in villages, some of which have developed as centers of experimentation on sustainable living throughout the years.
