A solution as simple as a sunflower…

Friday, February 26th, 2010

How do you get electricity to undeveloped places at a cost that makes it truly viable?  Sometimes the answer is not in a high tech application of newer technology, it is sometimes the answer is really far more low tech and genius in its simplicity.  First off, we put solar panels all over the place and to make sure that they are as efficient as possible, we have come up with a variety of technological solutions.  However, to make these solutions, you have to add thousands of dollars to the cost of solar power.  This starts to put it out of reach for many.  If you are living in an undeveloped country, then it is practically impossible.  We take electrical production for granted here in the US.  But in places like Africa, they often do not even have enough reliable electricity to power simple units that make it possible to operate hospital equipment or to keep blood or medications refrigerated.  Enter Chris Clark and his company Sunflower Solutions.

While in college getting his degree at the University of Miami Ohio, Chris worked with some classmates to create a way to power an electric well.  The plan was to help his buddies find a way to support developing nations who had little or no access to water.  His idea was the simple solar panel.  The problem with solar panels is not the cost in itself, but really the cost of making them efficient.  A stationary solar panel is far less efficient than one that tracks the sun.  The problem with the systems that track the sun is that they are cost prohibitive for most people, and for places like an African village, practically impossible.  Chris came up with an ingenious answer.  Figure out a way to make a stand for a portable unit that could be used by anyone, regardless of location and language barriers.

These solar panels together will generate about 16.8kwh, that is enough electricity to power about half of the average American household.  For a hospital in a developing country that means incubators, stable blood supplies, and medications that need to be kept cool.  For a school that means better food or computers to learn on.  For a village, it might mean a water pump for a well or irrigation for a dry field, providing food for those in need.

What makes them so productive is the way they can easily track the sun.  The complex calculations of the seasons, global positioning and time of day have been reduced to an easy to understand series of markings.  These units are designed to be portable, which means they can be deployed all across the planet and even moved to where the need is greatest.  The stands are also designed to be easily assembled and have few parts that are easily broken.  This means that when deployed to the middle of a country like Chad, that there is little chance of the unit being rendered unusable for long periods of time-a problem with some hi tech systems.  The simplicity of the design also means that you can train villagers to use the systems themselves and help to make them self sufficient.

So who are Chris’s clients?  He is marketing to charities and those around the world that are doing good works.  These are the folks who are already doing the work to help those in need in underdeveloped countries.  The units are fully customizable based on the needs of the client.  The price for one of these units ranges from about $10,000 to $14,000. The low tech solution keeps th price within reason, and allows a charity in Africa to produce a heck of a lot more electricity than they would otherwise be able to produce for their money.  It also allows them to ship them nearly anywhere and leave them to be operated by the locals.  What is amazing is Chris’s passion for solar power.  He gets excited in what he does and shows a dedication that is rarely seen these days.  Just read the Sunflower Solutions mission statement:

Around the world, 1.6 billion people do not have power. One in 12 people is malnourished, 1.1 billion are without clean drinking water, 2.4 billion are without proper sanitation, 2.1 billion do not have an education, and 1 billion people do not have appropriate medical care.

That’s hard to imagine since most of us will never know what it’s like to be a part of one of those statistics. Still, around the world these problems persist and threaten the lives of millions of people every day. But how do we provide health care without first powering health centers? How do we educate without having access to lights, computers, or the internet? How do we bring clean water without a means to power the water pumps? How do we feed the hungry without first helping farmers irrigate their fields?

Sunflower Solutions’ mission is to eliminate life threatening conditions around the world by bringing low cost and reliable power to areas where it is needed the most. We seek to EmPower education, health, clean water, agriculture, and businesses that struggle around the world. Using the flexibility of solar technology to generate power, along with a little practical ingenuity, Sunflower Solutions sells the lowest cost power solution for the developing world.

Come see for yourself!  Next month Chris will be the featured speaker at Eco Tuesday.  Eco  Tuesday is a group with a three year history of gathering, educating, and promoting sustainability across the country.  Last week was the launch of the Cleveland chapter and the speaker was Brad Masi of the New Agrarian Center.  Held the 4th Tuesday of the month, March’s event will be held at the Key Club.  Come and hear about Chris and his company Sunflower Solutions.  Already written about in the Plain Dealer, this is likely to be a packed event, so RSVP right away.

What the heck in an REC?

Wednesday, February 17th, 2010

REC stands for Renewable Energy Credit.  Every solar panel and wind turbine around the country generates electricity from a renewable source, as do hydroelectric sources.  In addition to the electricity that is created, a credit is created based on the amount of power that is produced.  For example, if a solar panel is installed on a business, it will generate electricity that the business can use.  If it doesn’t use it all, it can sell it back to the grid.  In addition, that company also gets a credit.  This credit is completely separate from the electricity and varies by the amount of electricity that they are creating.  Other sources of renewable power create credits as well, and the amount of credits vary from one power source to another.

What good are these darn credits?  First off, you can use them in your carbon footprint calculations.  The more credits you produce, the more carbon you are offsetting from your use.  But this is the 21st century and we have found a way to make money on anything.  In much the same way that you can buy gold or other goods for your World of Warcraft account, you can buy and sell these Renewable Energy Credits.  So, if you install a solar panel on your home or on your business to make your own electricity, you can also sell off the credits that are created along with the power.

Who wants these RECs anyway?  If you are a homeowner or a small business, these credits may not do you much good.  Sure, you can claim the bragging rights of producing less carbon dioxide, or spend less to become “carbon neutral,” but you can do little else with them.  However, utilities are being required to get more and more of their electricity from renewable sources.  In Ohio, a percentage goal of a utility’s energy production has to come from alternate sources-that is sources other than coal.  The goal standard is 25% from alternate sources.  12.5 % of that has to be renewable energy-0.5% has to be solar electric.  Additionally, they cannot wait until 2020 and start, they have to show annual percentage increases.  Let’s face it, we are not seeing the huge solar panel grid systems going up that would enable Ohio utilities to reach these goals.  However, they can purchase the credits they need from other producers of electricity.  These credits (Ohio Renewable Energy Credits) are created by anyone producing electric power within the state.  Since the state mandates are already in place, utilities are trying to buy the RECs from everyone they can that has a solar panel up.  The more credits that they buy, the less alternative energy they will have to produce on their own.

If you have a solar panel on your home or small business, you probably have already been approached to sign a contract for the REC from your panels.  Even small producers have some sort of credit, even if it is only a partial one and has to be bundled with several others for it to count toward the utilities’ goals. Signing a contract with any company means that they will effectively own those credits for the length of the contract.  You will still use your own electricity that you generate, and sell back to the grid any excess.  The credits are a completely separate commodity from the underlying energy itself.  As such, their value will fluctuate and is in no real way tied to the price of electricity.  This means that by selling off you RECs you can help accelerate the return on your investment in solar power.  You can contact Erika at RePower Solutions if you want to know more: erika@repowersolutions.com
