We have a long way to go! Here’s the breakdown…
From cars to streetlights to irrigation pumps to remote communications towers, solar photovoltaics have many applications in our every day lives. Have you seen the inexpensive landscape lights you can buy at your favorite hardware store? They are actually quite an impressive combination of solar photovoltaics, LED light and reflector, rechargeable storage battery and control circuitry. Did you know that the typical rooftop photovoltaic panel can have a warranted life of 25 years and will likely produce 80% of its output up to 50 years or longer? With every day that we expand their use, envoronmentally clean and sustainable photovoltaics become more and more commercially viable.
Solar energy is the Earth’s most available source of energy, easily capable of providing many times over the Earth’s total current energy demands. The Sun’s power is about 386 billion billion megaWatts. Almost all the energy on Earth comes from the Sun. What would the Earth be without the Sun? The answer is ice with no life to speak of. Plants grow because they get energy from the Sun and even fossil fuels are just energy stored from the Sun over millions of years that is released when burned.
What is the fundamental very easily collected and very inexpensive earthly material that photovoltaics are made from? PV cells are made of a semiconducter material, typically crystalline silicon which mostly comes from common beach sand. Mathematicians at the University of Hawaii tried to guess how many grains of sand are on the world’s beaches. They came up with 7,500,000,000,000,000,000, or seven quintillion five quadrillion grains of sand.” That doesn’t include the deserts! An easily collected and very abundant resource…if not already being used of course…
The Americas solar photovoltaics market more than doubled in the first half of this year to reach 1.7 GW and is set to reach almost 4.3 GW for the full year, according to IMS Research’s third-quarter PV Demand Report.
Installations in the Americas grew by more than 120% in the first half of this year and will help drive the global PV market to grow by at least 3 GW this year, according to the research firm.
Welcome to Sunlution’s new blog and web site. For many obvious reasons, we like PV and are bound and determined to help proliferate it as a viable commercial energy source.
