Solar Thermal Systems

What are Solar Thermal Systems?

Solar thermal systems, also known as "solar thermal collectors" collect heat energy from sunlight converting sunlight into usable thermal energy. 

Solar thermal systems are typically mounted on a south-facing roof, with no obstructions (trees, hills, buildings) that would cause shading over solar thermal systems, at any time of the day.

Solar thermal systems are classified as low-, medium-, and high-temperature collectors:

• Low-temperature collectors provide low-grade heat (less than 110 degrees Fahrenheit), through either metallic or nonmetallic absorbers, and are used in such applications as swimming pool heating and low-grade water and space heating.
  

• Medium-temperature collectors provide medium-grade heat (greater than 110 degrees Fahrenheit, usually 140 degrees to 180 degrees Fahrenheit), either through glazed flat plate collectors using air or liquid as the heat transfer instrument, or concentrator collectors that concentrate the heat of incident insolation to greater than "one sun" and are mainly used for domestic hot water heating. Evacuated tube collectors are also included in this category.
  

• High-temperature collectors are parabolic dish or trough collectors designed to operate at a temperature of 180 degrees Fahrenheit or higher, and are primarily used by utilities and independent power producers to generate electricity for the grid.
  

The solar thermal systems performance rating is an analytically-derived set of numbers representing the characteristic all-day energy output of the solar thermal systems under standard rating conditions, measured in Btu per square foot per day (Btu/ft²/day). 

In 2009, the average solar thermal systems performance rating for low-temperature solar thermal systems (metallic and nonmetallic) was 1,239 Btu/ft²/day, medium-temperature (air) was 971 Btu/ft²/day, medium-temperature (integral collector storage/thermosiphon) was 913 Btu/ft²/day, medium-temperature (flat plate collectors) was 981 Btu/ft²/day, medium-temperature (evacuated tube collectors) was 973 Btu/ft²/day, medium-temperature (concentrator) was 2,196 Btu/ft²/day, and high-temperature (parabolic dish/trough) was 1,262 Btu/ft²/day.

What is a Flat Plate Collector?

Flat plate collectors are one type of solar thermal collector that collects heat energy from sunlight converting sunlight into usable thermal energy.  Flat plate collectors are typically mounted on a south-facing roof, with no obstructions (trees, hills, buildings) that would cause shading over the flat plate collectors, at any time of the day. 

Flat plate collectors have glass covers that enclose a black absorber surface and insulation.  In some flat plate collectors, a heat transfer fluid is pumped through the tubes inside the flat plate collector.  The heat transfer fluid cools the collector and transfers the heat energy after discharge from the flat plate collector.  

The efficiency of flat plate collectors varies throughout the day.  Maximum solar thermal efficiency of flat plate collectors occurs between the hours of 9:00 a.m. and 4:00 p.m.  The efficiency of flat plate collectors is maximized when the surface of the flat plate collector is normal to the incoming sunlight.  Some flat plate collectors "track" the sun as the sun moves from east to west which maximizes the surface area and incoming solar energy.

What are Evacuated Tube Collectors?

Evacuated Tube Collectors are very efficient "solar thermal collectors" that convert sunlight into solar thermal energy.  Evacuated tube collectors are typically the main part of a solar water heating system, producing up to 100% of the domestic hot water for the home or building.

Evacuated tube collectors are sometimes referred to as "heat-pipes" and are far more efficient than flat plate collectors at generating heat energy.  But also cost about twice as much as flat plate collectors.  

Evacuated tube collectors acts as a thermos bottle as they are very efficient in retaining the solar heat energy they collect.  Evacuated tube collectors are made up of individual sealed, glass tubes which are under a vacuum.  A heat transfer fluid that circulates through them absorbing the sun's heat energy.

Evacuated tube collectors are typically mounted on a south-facing roof, with no obstructions (trees, hills, buildings) that would cause shading over the evacuated tube collectors, at any time of the day. 

What is a Power Purchase Agreement? 

A Power Purchase Agreement is a legal agreement wherein our clients agree to buy either the power (electricity) or the power and energy (hot water, steam and/or chilled water for air-conditioning) - or both - directly from us, for a term of 10 to 20 years, where we have installed, own and operate our solar energy systems. 

In nearly every case, once we have installed our solar energy systems at our client's facility, we can immediately reduce our (commercial) client's electricity expenses by 10% over what they were paying for their power electricity from their electric utility.

The right Power Purchase Agreement, solar cogeneration or solar trigeneration energy solution, may save your company hundreds of thousands, and possibly millions of dollars over the term of the agreement. Simultaneously, having the wrong or poorly drafted PPA can cost your company thousands or millions of dollars.  You wouldn't consult a brain surgeon to treat your child's broken bone!  Selecting the wrong attorneys, law firm or team to promulgate or re-negotiate your Power Purchase Agreement can leave you "powerless" and penniless - and still requiring the skills and expertise of competent and qualified professionals to resolve the situation.     

Because a Power Purchase Agreement is at the "heart" and underlying foundation of our projects, we can help your business with the selection and oversight of PPA's. 

We can help your city or community create a Municipal Utility District or Public Utility District that may then qualify for our very competitively priced energy and electricity rates. Now is the time for cities, municipal and governmental clients to consider having our company install one of our renewable power and energy systems that will generate "clean" power and energy, lower costs, and avoid the coming electricity shortages and grid congestion problems!

How we make and distribute electricity is changing! 

The electric power generation, transmission and distribution system (the electric "grid") is changing and evolving from the electric grid of the 19th and 20th centuries, which was inefficient, highly-polluting, very expensive and “dumb.”  

The "old" way of generating and distributing energy resembles this slide:

Hubbert's Peak Oil Predictions Now Proving True?

Marion King Hubbert was a geologist and scientist who worked at Shell Oil company's research lab in Houston, Texas.  Hubbert made several important contributions to geology, geophysics and petroleum geology.  Hubbert is most recognized for the "Hubbert Curve" and " Hubbert Peak Theory" which is now referred to as " Peak Oil. 

Hubbert's life work determined that the world has a finite amount of petroleum that can be produced.  (Similarly, there is a finite amount of coal.) Many scientists and engineers believe we have reached Hubbert's "peak oil" limit.  Hubbert's espouses that when 50% of domestic crude oil production has been reached, that there will be such significant upward demand on prices of the limited supplies of oil production, that the U.S. economy will experience severe economic, social, and political turmoil.

Hubbert's Peak Oil predictions have proven to be true and this is validated as the U.S. in the early 1970's produced about 60% of its' oil demand and imported 40%.  That equation has flipped since then, because our domestic oil production has been on the decline since 1970, so now, due to our declining domestic oil production, we have to import 60% of our oil supplies, to meet our country's oil/energy demands.

The Next Oil Shock Could be the "mother" of All Oil Shocks

How severe our economic calamity and next "oil shock" will depend upon a number of factors, including when this occurs, as well as the following:

1.  the dependence of the individual country upon its own crude oil production to meet its energy needs and to subsidize consumer imports; 

2.  the rate of relative decline in crude oil production; 

3.  the degree of difficulty encountered in replacing missing energy inputs; 

4.  the degree to which our country had prepared in advance for this inevitable geological and economic calamity.

Examples of past "oil shocks" and the economic and political calamities that followed:

United States: Our peak crude oil production of domestic oil occurred in 1970; the first "oil shock" and oil crisis followed in 1973 with the Arab/OPEC Oil Embargo.

Iran: Their peak crude oil production occurred in 1974; They had their islamic revolution 1979 that overturned government and replaced it with radical islam.

Soviet Union: Their peak crude oil production was in 1989; what happened next? 
Their country disintegrated and the collapse of the Soviet Union followed in 1991. 

Indonesia: Their peak crude oil production was in 1991; their financial and government crisis followed in 1997.

Iraq: Iraq's crude oil production was in 1989; they then invaded Kuwait (for their oil) in 1991.

Using Mr. Hubbert's predictions, that beginning around 2000  we would see peak (global) oil production, then, if the country's not weaning themselves off of their oil addiction, and had not begun making the switch to renewable energy, that the negative economic and political calamities would soon follow, including ever-increasing prices of energy that is from fossil fuels. 

Now is the time to begin weaning ourselves off of fossil fuels and making the transition to and increasing the use of renewable energy. If you don't believe in climate change, or global warming, GREAT! Join us in the switch to renewable energy and a fossil-free economy!

America's Clear and Present Danger

America Has INCREASED its' Dependence on Foreign 
Sources of Energy by 50% Since 1973.

America is even more "addicted" to foreign oil today, than we were in 1973 - 1974 when OPEC, Saudi Arabia and other suppliers from the Middle-East  stopped selling us their fossil fuels, and created a significant blow to our economy.

According to Monty Goodell, Founder and Chairman of the Renewable Energy Institute, "our increased dependence and reliance on foreign energy supplies represents a Clear and Present Danger to our national security, our economy, and the lives and livelihood of every American. Energy - including the energy we use from imported fossil fuels, is the very "lifeblood" of the American economy as it is for every industrialized country.  An economy dies without it's lifeblood of energy. This Clear and Present Danger we face is far more serious than the problems related to greenhouse gas emissions.  And while greenhouse gas emissions are very serious issue, in the long-term, pales in comparison to America's vital national security interests and America's economic stability in the short term.  For this reason alone, America needs to transition away from its addiction to foreign energy supplies. And America's abundant renewable energy resources such as the energy we receive from the sun, and renewable energy technologies such as concentrated solar power (CSP) plants - can supply 100% of America's power requirements with a concentrating solar power plant measuring 75 miles by 75 miles, located in the Southwest U.S.  By generating America's power from concentrating solar power plants, America resolves its' short-term Clear and Present Danger as it relates to importing its energy from foreign countries, and the long-term problems relating to greenhouse gas emissions."

Continuing, Mr. Goodell states that "too many Americans have forgotten what happened to us in 1973, when the Arabs and OPEC brought the United States economy to a screeching halt during the OPEC Oil Embargo.  This happened because they (mainly the country of Saudi Arabia) disagreed with our foreign policy and is the reason why they "turned off the tap" of our need for their oil supplies. When Saudi Arabia and OPEC stopped the vital flow of oil to our country in 1973, they caused an "oil shock" that severely and negatively impacted our economy. 

Mr. Goodell's question for us to ponder is, "do these countries who sell us 60% of our daily energy requirements, like us and our foreign policy, or might they leverage our addiction to their fossil fuels, and turn off the tap to make us adjust or revise our foreign policy??  Like any addict, America's foreign policy may be held hostage to its addiction, and in this case, our addiction to foreign oil, may over-ride our national interests."

Have American's forgotten the gas shortages and long lines at 
their gas stations to get gas during the Arab Oil Embargo of 1973? 

"Apparently so."  Mr. Goodell states that "in 1973, America was 'addicted' and 'over the barrel' of foreign oil to the amount of 40%.  Forty percent of our energy 'needs' in 1973 came from countries - many of which didn't like us then, and I'm afraid, many of them still don't.  The difference between 1973 and today - is that today we receive 50% MORE foreign oil now than we did in 1973.  And now we know about the problems relating to greenhouse gas emissions that we didn't know then.  America needs to change course, and change course now, in terms of its' energy supplies and how we keep America's economy strong, without the threat of being held hostage to a middle-east tyrant or regime, that could once again, turn on us, and turn off our supply of foreign oil." 

Remember ????

"Sadly," Monty Goodell continues, "most Americans have forgotten the long lines of people waiting in their cars - lined up and waiting for gasoline at their nearby gas station, with lines that were many blocks long.  And, after waiting 4-5 hours, many even waiting overnight in many places, to finally take their turn to fill up their car with gasoline, only to find that the gas station had run out of gas." 

"Let me Repeat.... That was 1973 when we imported 40% of our daily energy requirements in the form of crude oil from overseas, and from foreign countries - and many of these from countries that don't like us.

Today, over 35 years later, America has yet to learn the lesson.  We cannot continue our reliance on energy from foreign countries that supply us with 60% of the crude oil that our refineries use as a feedstock for producing gasoline and diesel fuel for our cars and trucks comes from overseas. 

America is "over the barrel" and it's not our barrel, but the barrels of oil that we are addicted by and owned by other countries.  Why have we not learned the lessons we needed to learn in 1973 when we were cut-off from the vital energy supplies we need? 

Countries like China, are growing rapidly, and have an insatiable need for crude oil. China, with their booming economy, is increasingly growing in its clout and control over international supplies of crude oil - whether they do this through their ability to buy as much oil as they need on a daily basis, or whether they simply but American drilling rigs, technology, and explore and produce oil and gas from their own fields. China, is buying large amounts of oil for their country, and causing upward pricing on declining supplies. What happens if Russia, with all of their oil and natural gas, along with China and Venezuela, with or without the help of OPEC, decided to NOT sell oil to us????

To be sure, greenhouse gas emissions are a problem, and to some, greenhouse gas emissions are also a Clear and Present Danger, but not to the extent that it presents an imminent Clear and Present Danger. 

America's reliance for 60% of our energy "needs" coming from foreign suppliers is un-acceptable.

The "driver" to get America to begin reducing and eliminating fossil fuel use should be our nation's national security and the welfare and safety of its citizens. And this can all begin with developing and investing in our own renewable energy resources and renewable energy technologies, let's start by putting solar on every rooftop that has a clear and unobstructed view of the Southern sky. See www.RooftopPV.com  or  www.DistributedPV.com  for more information.  Let's create incentives begin with adopting a national "Feed In Tariff" as Germany did in 1990. 

America, we simply do NOT have the luxury of time on our hands.  We need to end our dependence and reliance on foreign fossil fuels, especially from countries that don't like us! We need to rapidly begin expanding renewable energy resources and renewable energy technologies from our vast and abundant renewable energy resources, such as; solar, solar energy systems, solar cogeneration, solar trigeneration, "solar on every roof," waste to energy, waste to fuel, biomass gasification, B100 Biodiesel, Biomethane, Synthesis Gas, geothermal, E100 Ethanol (from sugar cane and NOT from corn), and wind, where it makes economic sense."
