Free Solar Panels Too Good To Be True?

Citizenre promises to install free solar panels on the roofs of thousands of customers who will pay the same price for electricity that they do now. Sound too good to be true? Maybe it is, according to an opinion piece on renewableenergyaccess.com. To date they have no factory and no funding, though they claim their funding is lined up.
So why is gambling on Citizenre's plan a problem? Author Jeff Wolfe sees it this way:

As soon as someone signs up for a Citizenre solar system, they are removed from the pool of potential customers for other reputable solar dealers in the U.S. Already, photovoltaic (PV) dealers are telling me that they are losing business because potential customers are signing up with Citizenre -- people are waiting until the reported 500 megawatt "largest fully-integrated PV manufacturing plant in the world" comes online this fall.But it will be September -- the deadline for the build out of the manufacturing facility and beginning installations will have come and gone -- before reality sets in for these customers when they do not receive their solar system on time as promised. Plans seem poised to fall apart, and at that point we'll have four results:

* A lot of very disappointed and upset people.

* A lot of traditional PV dealers who are out of business.

* Reduced or eliminated federal and state incentives for solar electricity due to a perceived lack of need.

* A solar electric industry in the U.S. that has been set backwards 5 years.

MANDATORY RENEWABLE ENERGY – THE ENERGY EVOLUTION –R13

In order to insure energy and economic independence as well as better economic growth without being blackmailed by foreign countries, our country, the United States of America’s Utilization of Energy Sources must change.
"Energy drives our entire economy.” We must protect it. "Let's face it, without energy the whole economy and economic society we have set up would come to a halt. So you want to have control over such an important resource that you need for your society and your economy." The American way of life is not negotiable.
Our continued dependence on fossil fuels could and will lead to catastrophic consequences.

The federal, state and local government should implement a mandatory renewable energy installation program for residential and commercial property on new construction and remodeling projects with the use of energy efficient material, mechanical systems, appliances, lighting, retrofits etc. The source of energy must be by renewable energy such as Solar-Photovoltaic, Geothermal, Wind, Biofuels, Ocean-Tidal, Hydrogen-Fuel Cell etc. This includes the utilizing of water from lakes, rivers and oceans to circulate in cooling towers to produce air conditioning and the utilization of proper landscaping to reduce energy consumption. (Sales tax on renewable energy products and energy efficiency should be reduced or eliminated)

The implementation of mandatory renewable energy could be done on a gradual scale over the next 10 years. At the end of the 10 year period all construction and energy use in the structures throughout the United States must be 100% powered by renewable energy. (This can be done by amending building code)

In addition, the governments must impose laws, rules and regulations whereby the utility companies must comply with a fair “NET METERING” (the buying of excess generation from the consumer at market price), including the promotion of research and production of “renewable energy technology” with various long term incentives and grants. The various foundations in existence should be used to contribute to this cause.

A mandatory time table should also be established for the automobile industry to gradually produce an automobile powered by renewable energy. The American automobile industry is surely capable of accomplishing this task. As an inducement to buy hybrid automobiles (sales tax should be reduced or eliminated on American manufactured automobiles).

This is a way to expedite our energy independence and economic growth. (This will also create a substantial amount of new jobs). It will take maximum effort and a relentless pursuit of the private, commercial and industrial government sectors’ commitment to renewable energy – energy generation (wind, solar, hydro, biofuels, geothermal, energy storage (fuel cells, advance batteries), energy infrastructure (management, transmission) and energy efficiency (lighting, sensors, automation, conservation) (rainwater harvesting, water conservation) (energy and natural resources conservation) in order to achieve our energy independence.

P.S. I have a very deep belief in America's capabilities. Within the next 10 years we can accomplish our energy independence, if we as a nation truly set our goals to accomplish this.
I happen to believe that we can do it. In another crisis--the one in 1942--President Franklin D. Roosevelt said this country would build 60,000 [50,000] military aircraft. By 1943, production in that program had reached 125,000 aircraft annually. They did it then. We can do it now.
"the way we produce and use energy must fundamentally change."
The American people resilience and determination to retain the way of life is unconquerable and we as a nation will succeed in this endeavor of Energy Independence.

Solar energy is the source of all energy on the earth (excepting volcanic geothermal). Wind, wave and fossil fuels all get their energy from the sun. Fossil fuels are only a battery which will eventually run out. The sooner we can exploit all forms of Solar energy (cost effectively or not against dubiously cheap FFs) the better off we will all be. If the battery runs out first, the survivors will all be living like in the 18th century again.

Every new home built should come with a solar package. A 1.5 kW per bedroom is a good rule of thumb. The formula 1.5 X's 5 hrs per day X's 30 days will produce about 225 kWh per bedroom monthly. This peak production period will offset 17 to 2

4 cents per kWh with a potential of $160 per month or about $60,000 over the 30-year mortgage period for a three-bedroom home. It is economically feasible at the current energy price and the interest portion of the loan is deductible. Why not?

Title 24 has been mandated forcing developers to build energy efficient homes. Their bull-headedness put them in that position and now they see that Title 24 works with little added cost.

Disenco Energy of the UK has announced it has reached important
milestones leading to full commercialization, such as the completion of
field trials for its home, micro combined heat and power plant (m-CHP).
The company expects to begin a product roll out in the second quarter of
2008.
Operating at over 90 percent efficiency, the m-CHP will be able to
provide 15 kilowatts of thermal energy (about 50,000 Btu’s) for heat and
hot water and generate 3 kilowatts of electricity. The m-CHP uses a
Stirling engine generator and would be a direct replacement for a home’s
boiler.
Running on piped-in natural gas the unit would create some independence
from the power grid, but still remain connected to the gas supply
network.
Whereas heat is supplied only when the generator is running (or
conversely electricity is generated only when heat is needed) a back-up
battery system and heavily insulated hot water storage tank seem
eventual options for more complete energy independence.

ERV Energy Recovery Ventilation Systems Reduce Long Term Costs and Improve Indoor Air Quality

Is the indoor air your breathe is as fresh and healthy as it can be?

As building science professionals have known for some time, an effective ventilation strategy is an absolute requirement for all homes. Mechanical ventilators exchange air inside the home with fresh air from the outside. This helps to reduce indoor pollution levels, and greatly increases the comfort level inside the home.
Many ventilation designs are including Energy Recovery Ventilators (ERVs) to improve the system efficiency. Besides providing controlled ventilation, ERVs are able to filter, humidify, dehumidify, heat, or cool the incoming fresh air. The most popular design of ERVs utilizes a desiccant wheel to remove both heat and a significant amount of moisture from the incoming air, which reduces the load on the air-conditioning system. But while ventilators and ERVs can add tremendously to the comfort and efficiency of a home, they must be installed correctly.

One of the more recent developments in the ‘green’ technology industry is the creation of environmentally-friendly buildings that use energy-efficient technologies to reduce power consumption.

Energy consultants point out that creating ‘green’ buildings and improving the air quality inside such facilities utilizing ERV can and do go hand-in-hand. ERV Systems that reduce demand for energy while improving ventilation are increasingly in demand.

ERV – Energy Recovery Ventilation systems saves energy, increases indoor air quality, reduces contaminates and odors.

The use of ERV technology “energy recovery ventilation systems,” or ERVs. Such systems are designed to reduce energy consumption and improve indoor air quality (IAQ) by capturing and recycling building energy to humidify, pre-cool or dehumidify incoming air.

ERVs, the research first said, are most popular in areas with more extreme outdoor temperatures, like Northern states where winters can get quite cold, or Southern states where very warm temperatures and high humidity demand more energy consumption to maintain comfortable indoor environments.

“The focus on IAQ is another key trend benefiting ERV, as people become increasingly conscious of the importance to maintain air quality through properly designed and managed HVAC systems,” Energy consultant said in the energy audit survey.

Market growth for ERVs, Energy consultant said, is driven largely by energy conservation policies that are challenging building custodians to reduce energy consumption for indoor climates. The firm cited as an example the 90.1 standard from American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) which currently dictates “energy recovery systems for applications of 5000 cubic feet per minute (cfm) and larger with 70 percent outside air (OA).”

ASHRAE 90.1 is a standard that specifies at least 50 percent total effectiveness for ERVs, Energy consultant said.

The Air Conditioning and Refrigeration Institute and the U.S. Environmental Protection Agency also have various standards and regulations regarding energy recovery and IAQ.

Energy Consultant said two main obstacles lie in the way of more widespread use of ERVs: lack of knowledge and the need to reduce operating costs in the short term. Since building owners and facility managers rely for the most part on contractors to select and install heating, ventilation and air-conditioning (HVAC) equipment, if the contractors are not up-to-speed on ERV developments they may pick products that aren’t as energy-efficient as they could be.

Also, Energy consultant noted, HVAC contractors work within budgets and therefore tend to buy equipment based on its price rather than long-term cost benefits. It therefore is important to educate contractors about ERVs, and some of that burden falls on manufacturers. The Green Building Council is also playing a role through its Leadership in Energy and Environmental Design program that evaluates buildings to determine the environmental performance during their entire lifecycle.

ERVs aren’t just good for the planet; they’re good for people, too.

“The focus on IAQ is another key trend benefiting ERV, as people become increasingly conscious of the importance to maintain air quality through properly designed and managed HVAC systems,” Energy consultant said in the report.

When IAQ isn’t managed properly, people living or working in unhealthy buildings can develop sick building syndrome from pollutants in the air they breathe.

“With half of all illnesses attributed to indoor airborne contaminants, the U.S. Environmental Protection Agency (EPA) has declared IAQ a public health priority,” Energy consultant said. “Ventilation with outdoor air is the only strategy that can simultaneously reduce the levels of all indoor pollutants.”

ATTIC FANS AND WHOLE HOUSE FANS CAN SAVE YOU MONEY ON AIR-CONDITIONING
Efficiency in cooling is the name of the game for homeowners who like to stay cool. One source of added efficiency often overlooked is the attic fan. There are two types of attic fans, one cools only the attic and is properly called an attic fan, the other one is really a whole house fan and cools the whole house using outside air instead of air conditioning. Both fans can be used with satisfying results.

WHOLE HOUSE FANS
Many people use whole house fans as an alternative to air-conditioning. A whole house fan is most effective when outside air temperatures are below 82ºF. It brings a cooling breeze in through the windows of the home and cools more efficiently than an air-conditioner (Click on picture to enlarge).

Some times central air-conditioning is too expensive to install. When a house has been originally built with hot water radiator heat, installing central air-conditioning can be cost prohibitive because there is not any ductwork to distribute air throughout the house. Also, a whole house fan only uses about ¼ of the power that a central air-conditioning system does. Some people just don’t like air conditioning or may want the option of using outside air for cooling and ventilating their homes. Whole house fans draw massive amounts of air through a home. Moving air feels cooler than still air so high volumes of air are usually preferred.

One objection that some people have with whole house fans is the sound that is created when running. There are basically three types of noise created: air noise, motor vibration and shutter rattle. A well-engineered whole house fan will address all of these issues.

Generally speaking the more blades a fan blade has the quieter it will be, (five blades are better that four). Each blade does less work and thereby creates a smoother, even sound as opposed to fewer blades where the sound is choppy and irritating. One strategy for sizing a whole house fan for a house is to get the largest fan that will fit into the ceiling area of a hallway where a fan would typically be installed. Any size fan will be quieter when run at a slower speed; so by getting a large fan that has a low speed you can get less noise and still move a high volume of air because of the large size. Running on low speed also creates less wear and tear on the fan and saves electricity. Better whole house fans will have the whole fan isolated from the homes framing with foam strips or rubber mountings that will not transmit sound into the framing of the house. This keeps the motor hum from resounding through the framing and drywall of the home. It is better to have no direct mechanical connection to the house framing. Heavier fans are better because they rest on foam weather stripping held down only by their own weight.

Higher quality shutters will be heavier and have connecting rods connecting vanes of the shutter so they act together. This prevents one or more vanes from oscillating and possibly clapping shut and re-opening. Also, a better shutter will have an adjustable spring that will assist in opening the shutter as the fan sucks it open and cushion and slow the closing when the fan is shut off. This prevents the shutters from creating a loud thump when shutting when the fan is turned off. Some shutters even have a felt strip at the edge of each vane to seal in air when the fan is off and to silence the shutter when it closes.

Having as timer is also a good idea. A timer will let the fan run a pre set length of time so that you can set it before going to bed an have it shut off automatically when you feel it may get too cold at night. Thermostats are not a good idea because they could turn the fan on when no one is home and preparation hasn’t been made for it to come on. Windows must be opened first. Also, a fire in the fireplace could trigger it to come on unexpectedly with danger of sucking flames in from the fireplace. Obviously, some caution must be used when operating a whole house fan. The drill is really pretty simple: turn off heating and air-conditioning, open windows, no fires in fireplace and then turn the whole house fan on. Without opening windows first, some air could also be drawn down other vents or chimneys for heating and water heat, possibly blowing out pilot lights.

The amount of work required to install a whole house fan varies from house to house, but can generally be retrofitted into an existing house by a professional in about 8 to 16 man-hours. One major variable is the venting, if you plan on running the fan on high speed, (most people do) you need to make sure that there is at least enough exhaust venting for high speed setting. Fans are rated by cubic feet of air per minute or cfm. A good rule of thumb is to provide one square foot of net free venting area for every 750 cfm. Net free venting is the area after subtracting for louvers and screens. Generally the vents are roof vents, louvered wall vents or eave vents. Some roof vents and some eave vents have their respective net free venting areas stamped right on them. Ridge vents, depending on type, are not as good for providing the bulk of vent area needed although they do help slightly.

One strategy is to get an attic fan with a whole house fan. Special timer switches (DPST) are available and when installed they will turn on both fans to help expel some of the air being pushed into the attic. It is important to use only this type of switch for this application, because with a normal switch the attic fan thermostat would back feed and run the whole house fan even when the homeowner has not selected the on position for the whole house fan switch.

Better whole house fans have a welded frame. Effectively they are one-piece construction using heavy gauge steel for the venturi and motor and fan supports. This type of construction is better because it will never loosen up or begin to squeak. The only problem might occur if the installer was trying to fit the fan into a very small attic space; it may not fit through the opening when turned up on end before hitting the roof. Fans that can be disassembled can be fit through and then reassembled in the attic. One strategy for installing a welded frame fan into a smaller attic is to use a larger shutter than is required so the fan could be lifted into the attic in a horizontal or flat position and then supported by ledger strips around inside of opening. The larger shutter would then fill the larger opening that was made in order to lift the fan through in flat position.


ATTIC FANS - SOLAR & ELECTRIC
When the temperature climbs above 82ºF and you decide to use air conditioning, you can shut the windows and crank up the air knowing that the attic fan will save up to 30% on cooling costs by getting rid of trapped super hot air that tends to collect in attics and cause heat to back up into the home. (Click on picture to enlarge)

Attic temperatures can get up to 150ºF without an attic fan. Attic fans create a positive air-flow through your attic that does not rely on wind or require excessive passive venting. Excessive passive venting can cause excessive moisture infiltration in the form of snow or rain. The attic fan is normally mounted up on the roof of the home toward the back about two feet down from the peak. It goes on and off automatically with a thermostat, so it only runs when it is beneficial. The attic fan has a flashing that fits in with the shingles and is water-proof. Attic fans use less than 300 Watts, and offer these important advantages:

1. Lowers upstairs room temperatures by 10º.
2. Lengthens roof life by keeping shingles cooler.
3. With an optional humidistat, keep attics dry during winter months.
4. Saves up to 30% on air-conditioning costs.

The exact savings obtained depends on several factors like: the color of your roof, if the home is shaded, the amount of insulation you have, and the efficiency of your cooling system. Ideally, an attic fan installation will pay for itself within 3 years. A high quality attic fan is recommended. A heavy screen is required to stop pests. All metal construction is preferred as plastic fans do not hold up as well and over time will crack. A quality thermostat is also essential to save from climbing up into the attic for resetting. A firestat, which shuts the attic fan off for extremely high temperatures, is needed in case of a home fire. A permanently lubricated motor, insures quiet, maintenance-free operation.

There are 2 types of attic fans: roof top, and gable-end. Attic fans can be electrical or solar powered.
