Ulquorria Schiffer asked:


If you were to be asked to write a material(s) report on either
-solar panels
or
-aircraft fuselage
Which would you choose?

well i was asked to choose between these two,so i guess that if i choose what the majority wouldn’t, i might just score a little bit higher,what do you think?if you are the lecturer you would want something different right?

What do you get when you mix chocolate and wine? In the case of Clean Solar, Inc., you get solar. Silicon Valley Entrepreneur, Randy Zechman, is the founder of City Chocolate Fountains (the largest chocolate fountain rental company in the United States). Jeff Ritchey is a San Jose native and wine guru. He is a wine consultant for Pichetti Winery, San Saba winery, and has two of his own labeled wines. Together, they are the co-founders of Clean Solar, a Silicon Valley solar installer and integrator.

Randy Zechman will readily admit that he is a serial entrepreneur. Just over a year ago, with two successful businesses in his portfolio: City Chocolate Fountains and World 2 Do, Inc., Zechman was ready for a new challenge. Zechman and a friend of eight years, Jeff Ritchey, an award-winning winemaker, regularly attended a monthly Bay Area speaker series with a group of friends. After every speaker they would end up at a local restaurant debating the subject matter of that night’s speech, global warming and the health of the earth were often the center of those debates, which resulted in them seeing Al Gore speak at the State of the Valley conference in early 2007.

After seeing Al Gore speak on solutions for protecting our planet, Zechman began to research the solar power industry. Ritchey, while continuing to grow his label, Sensorium Wines, was also showing increased interest in the green movement, realizing that green technology was an ideal fit with his knowledge in geology, winemaking and construction.

Zechman knew that the scientific and construction skill set that Ritchey could bring to the table would be the perfect compliment to his business and marketing skills, which led him to approach Ritchey about starting a solar power company.

Zechman and Ritchey met weekly for 6 months, discussing the in and outs of the business and making sure that their ambitions would not get in the way of their friendship. “We had a heart to heart regarding our friendship versus business. We both believed we could manage both and that our friendship would not get in the way.” says Zechman.

“We’ve been friends for eight years and never thought about getting into business with each other, but this presented the right opportunity. With the market timing, our passion for doing something good, Randy’s sales and marketing experience and my technical and construction abilities, we figured it was a natural fit.” says Ritchey.

Clean Solar Inc. quickly became a reality and is now the Bay Area’s leading solar installation company. The fuel for their business growth is in the form of state rebates through the 10 year, $3.4 billion California Solar Initiative. While silicon is still in short supply, the rebates offer customers a chance to significantly lower the installation cost of a solar power system. Zechman and Ritchey are committed to staying ahead of the curve and being early adopters of new solar technology as it comes on line. “We want the Clean Solar team to stay abreast of the latest advancements in technology, maintain certifications, and educate ourselves in order to provide our customers with the knowledge they need as a solar owner.” says Zechman.

Maud The Skivvy asked:


My husband and I are interested in becoming a little more eco friendly and would like a windturbine and some solar panels for our house.

How much might these cost? Are there government grants available to help pay for them (I’ve heard there are)?

Who would install them?

Do I have to seek planning permission etc.?

What would be the first step?

I’m in the UK, by the way.

rticle, we will document the three most common types of solar cells and how this technology has proven itself for decades. We’ll also give a brief history of silicon sourcing and explain why we were set for rapid growth back int the 90s and now we are again. Finally, we’ll make note of new solar technologies that will change the solar industry as we know it (i.e. thin film and nano-solar). All of these factors are great news for homeowners wishing to upgrade to solar generated electricity.

The following topics will be explained in varying levels of detail; how a solar cell converts sunlight energy via the use of different types of silicon, the use of silicon and where it comes from, and a little about the history of silicon sourcing over the past 18 years.

The Future Solar Panel and Home Solar Manufacturing

As the residential solar power industry has matured and showed a steady growth of about 40 percent a year, the silicon industry is now responding with new production and caches of raw materials. Many silicon refineries and new silicon sourcing companies are getting the funding and moving towards rapid production in the next dozen or so months. There are plans and announcements by several companies such as GE, BP, and others about launching new facilities that produce silicon at a fraction of the cost we may be experiencing today. This is all exciting news for home solar power enthusiasts and for those wishing to upgrade to residential solar generated electricity.

The silicon industry is or has been slow to increase overall manufacturing capabilities because of the large growth during the early 1990s that eventually when stale. The extreme growth expectations were hyped and many industry experts expected much expansion in the early 1990s. This just did not happen 18 years ago. Fortunately, we are now experience much more accepting market, social expectations of our movement to renewable technologies, and governmental support to make the switch to home solar power.

In the past, the solar silicon refining industry made solar panel manufacturers sign long-term contracts at extremely high prices to secure any silicon at all. For example, a solar manufacturing plant had to slow production to a trickle because of a lack of silicon. The economics have now changed since 2006 making massive silicon contracts viable at better prices.

Nano-Solar and Thin Film Solar Cells: It’s the Future

We are now at the dawn of a home solar energy revolution. The solar power manufacturers invented and are beginning to manufacture new solar modules that do not use silicon at all. There are alternative materials using nano-technology that are and will continue to radically change the consumption and production of solar generated electricity.

Often the newest technologies, like thin film or nano-solar cells, are somewhat experimental with limited or no actual field testing. This is not true for many of the silicon based solar panels on the market today. Homeowners, right now, have the opportunity to rent residential solar energy systems and side step the expensive system purchase by renting. Because there are now large sources of silicon, homeowners now have the choice to upgrade to solar on a large scale across many markets in the United States that were once thought too expensive to install residential solar systems.

Sourcing of Silicon for Home Solar Energy Systems

The material used to make most solar cells today is the abundant element called silicon. One might think of this in a common sense as sand which when melted down and added to various other elements makes up anything from computer chips to beer bottles. Availability of solar grade silicon has been one of the limiting factors in the solar module manufacturing industry for the past several years.

The story goes something like this. Solar grade silicon is produced in large scale, expensive to build processing facilities. “Well, isn’t it just sand?” One might ask. Of course, sand is basically silicon, but with a lot of impurities. Solar grade silicon is highly refined silicon that is purified through gasification and then “doped” with precise impurities to create free electrons, which is explained in following articles.

There are basically 3 types of silicon going into current solar energy systems being installed today;

1. Silicon Crystals: A silicon atom has a positively charged nucleus that is surrounded by negatively charged electrons. The critical thing about silicon is its structure. It has 4 electrons around its nucleus that allow for easy bonding to other elements and for its organization into crystal. Crystals conduct electricity much better than randomly organized elements. The 4 orbiting electrons can bond to the other electrons rotating around different elements. Each silicon atom connects with 4 more silicon atoms to construct a perfect pattern, a repeating crystalline structure.

2. Monocrystalline Silicon: The silicon is grown as large cylinders, which are sliced into wafers that become individual solar cells.

3. Polycrystalline Silicon: Liquid silicon is poured into thin containers and cooled.

Emerging Availability of Home Solar Energy System

Want to know how to rent a home solar electric system for your house? Well, it’s pretty simple. You basically pay a flat monthly rental fee just like you do today for a satellite dish or some other equipment you rent. The solar system rental rate is calculated based upon a number of factors; the average monthly energy consumption, the available utility sources and net-metering options, and the kWh rates in your market. A solar engineer will come to your home, look at your roof size, angle and shading to size the system for your location.

Going solar and using renewable, solar energy is getting simpler every day. The following article explained in some detail why the sourcing of silicon has slowed in the overall residential solar power market in the past. This is just not the case any longer and more options are emerging daily for the average homeowner to rethink solar power and renewable solar energies.
