1. Renewable Energy from the Sun - Facts

Solar Power is an ecologically sound and desirable source of energy. Sunlight has been used by microbial, plant, and animal life as a primary energy supply. Photosynthesis is a process which also requires sunlight.

Earth's atmosphere absorbs about 3.85 million exajoules of solar energy. However by comparison, the entire use of electric energy, world-wide is about 56.7 exajoules annually. Thus, within a few hours, the earth receives more solar energy than people expend annually!

Renewable energy from the sun is a clean source of energy. In contrast to fossil fuels, using Solar energy doesn't discharge carbon dioxide or other types of harmful toxins into the environment. Furthermore solar energy is collected by almost every single form of life. Even animals bask in sunshine to warm themselves. Solar power is probably the most environmentally sound energy option attainable right now.

Every year, humans consume 467 exajoules of energy, mostly derived from fossil fuels. However, if we could capture just 10% of the renewable energy from the sun, we could replace all fossil fuel sources.

Solar Energy is the collective energy in form of heat and light energy emitted from the sun. Approximately 30% of this is immediately deflected by the atmosphere, and another 20% is absorbed into the atmosphere. However, approximately 50% of the solar energy reaches the earth's surface, where it fuels photosynthesis in plants, creates and maintains weather patterns and climates, as well as the temperature of the ocean, and generally speaking keeps our planet alive. All of this is accomplished without creating any pollution or destruction of natural resources.

In the last three decades, solar energy technology has developed at an accelerated rate. Solar energy is harnessed using PV solar power plants. Home Solar Power generation is now possible with rooftop installation of Solar panels. Solar energy can be employed to power practically any procedure you can visualize, from large-scale power generation for towns and cities to boiling a single pot of water.

Photovoltaic solar power plants use PV panel systems to produce electricity. This electric current may be used immediately or alternatively stored in batteries for later use. Battery storage is incredibly significant since it means it is possible to store solar power for use through the night or during cloudy or rainy days.

2. BIPV - Building Integrated Photo Voltaics for Clean Energy

BIPV refers to Building-integrated photovoltaics, which are photovoltaic materials, capable of harnessing solar energy, designed to be used in place of conventional building materials in the envelope of the building, e.g. the roof, skylights, or facades.

BIPV materials are becoming increasingly popular in the modern scenario, where “eco-friendly” and “green buildings" are the catch phrases. They are incorporated into the construction as a source of electrical power. Even existing buildings may be retrofitted with similar technology.

The term building-applied photovoltaics (BAPV) is used to refer to photo-voltaic materials that are a retrofit - integrated into the building after construction is complete. Most building-integrated installations are actually BAPV.

Building-Integrated Photovoltaic modules are available in several forms. Some of them are listed below.

Flat Roofs

thin film solar cell integrated to a flexible polymer roofing membrane is used for flat roof applications.

Pitched Roofs

Modules are shaped like multiple roof tiles.

Solar Shingles

modules designed like regular shingles, while incorporating a flexible thin film cell.

Glazing

(Semi) transparent modules can be used to replace a number of architectural elements commonly made with glass or similar materials, such as windows and skylights.

3. Sunny Side Up with Solar Energy

Apollo the mighty Sun God, brilliant yellow with a white halo, stands guardian to Mother Earth, as a provider of clean and green energy. Much like the “Florence Nightingale” He bears the magic lamp, waiting to deliver endless photons to all who care to harness.

Earth’s sources of Fossil Fuels are depleting faster than ever. The current outputs are falling short of the demand. Not to mention the ecological impact and carbon foot print. Burning fossil fuels releases pollutants like carbon dioxide, nitrogen monoxide, nitrogen dioxide, sulphur dioxide, carbon monoxide etc. These gasses have severe consequences on the habitats. A phenomenon called the “Acid Rain” is caused by sulphur dioxide. The smoking guns have been bellowing smoke rather too long, and I guess need to be silenced, to make our Mother Earth a healthier place to live in.

The Almighty Sun God, with his photonic generator offers us one of the much needed options out of this energy-dilemma. An article in NY Times recently published some eye-opening statistics. To make this planet cleaner, we need to re-think and re-plan our energy portfolio. The quaint source of endless energy is right there at the horizon. All we need to do is to have our sunny side up, with photo voltaic panels.
