The recession is rapidly clouding the clouds-
Solar manufacturers are growing.
California-based OptiSolar is laying off nearly half of its workers, and they hope it will become a huge solar enterprise.
Panel factory near Sacramento
Helio Volt, thin
Austin-based thin-film solar makers are also reportedly cutting jobs.
Solar maker Evergreen Solar announced it will close a pilot plant in Massachusetts in cashsaving measure;
Write-off equipment will charge $25 million.
Most employees will be transferred to another MIT plant that is expanding.
From the manufacturer\'s point of view, this is serious, Bill Stewart, president of California installation company SolarCraft, said in a conversation with Green.
Until last summer, there was still a shortage of solar components (
This is also due to the shortage of polysilicon materials)
So installers like SolarCraft sometimes have to pester manufacturers to make sure they get enough panels. Now, said Mr.
Stewart, the situation is reversed, the manufacturer called the installer and said, hey, what products do you need this month?
Can I sell you a little more? âx80x99âx80x9dMr.
The European solar market has also slowed, Stewart said, helping to ease supply.
SolarCraft still has a lot of buyers right now, he said, but that number would be higher if there were more innovative loan projects.
A lot of people don\'t want to mess up their home.
Equity credit lines, he said.
According to USA Today, the price of roof solar systems has dropped by 8 to 10% since October, and may drop further.
Comments are no longer accepted.
So we are doing a bail-out for industries that run companies and investors locally.
Where are the rescue and incentives for solar producers? These measures may help us get rid of fossil fuels. Solar manufacturers have entered the market with products that do not have any economic significance.
In addition to early adopters and PR, we need several generations of innovation.
Companies seeking will buy. 5-check in10 years.
So where are the cheap solar systems?
I will buy one if I can get a discount.
Just do math.
The price of oil is $38, the price of natural gas is less than $2/gallon, and the price of heating oil is about $2.
5. there is no economic incentive for solar installation.
Coupled with some state subsidies and the requirement that equipment can only be installed by \"certified\" solar contractors, one cannot help but wonder why there is any system.
If the government is really serious about reducing or ending our dependence on foreign energy, they will remove many restrictions (
Yes, believe it or not, there are bad laws and rules in the book)
Install this device
In addition to subsidies, they impose high enough restrictions on oil prices to ensure that these products can be used first.
Let\'s not delude ourselves, the economic future of this country (
Almost all others)
It is based on sufficient supply of cheap energy.
If energy costs increase to the point where these products are really cost-effective, then I\'m afraid it doesn\'t matter because the economy is going to collapse.
What we need is an energy policy that goes beyond the next round of elections.
Tom, the solar system installed today usually pays off for 15 years.
So I can hardly say that they are \". . . There is no product of any economic significance \".
I looked into buying a solar device for my home-they wanted a home for over $12,000 to generate electricity-without even hot water, plus years of maintenance agreements.
If the industry is hurt so badly, where is the discount?
Where is the transaction?
Why are there not every house nearby?
We should look at the solar industry like we saw computer chips 30 years ago.
In the past, computer chips were too expensive for all but the biggest commercial and government uses (
(Ministry of Defense).
Then, the government subsidized the cost of producing computer chips, and the PC was invented, and most of the commercial uses of this important product reached economies of scale.
This process continues to give birth to a new economy based on cheap and usable computing power.
Solar energy should do the same.
Subsidy for 10 years, expand demand, achieve economies of scale, reduce prices, and build a new industry based on cheap and clean energy.
Here we are . . . . . .
Just like in 70 years of passive solar design, coal has been promoted to energy projects.
The same song after 30 years.
Solar panels and other products cannot compete and people will not buy them because the electricity prices generated by oil, coal, etc. are not properly accounted.
While these industries are useful, they are burning our future into the air until oil and coal are more regulated and taxed from underground mining, and solar energy will never win.
It\'s like saying that stealing is cheaper than buying things.
That\'s true, of course, but it\'s theft.
Stewart, the government is right to subsidize the solar industry.
Back in their early 80 s, in Arizona, if you invest in a solar hot water system, they will cut taxes directly.
Tax incentives alone make their returns within two years. three years.
That\'s how you make a leap in an industry. start.
It\'s a pity that the green company.
Continue to include the Green City media in the \"news sources\" on its right \".
They lost their edits a few months ago and have been different since then.
Since they seem to be lost, they should either get her back or just give up.
We need to recognize that there is no silver bullet in the energy crisis \".
When two forms of energy emerge, the progress of energy and the expansion of the economy;
Coal for electricity and oil for heating and transportation are replaced by dozens of technologies.
When there are multiple options, they will compete with each other to lower prices and improve efficiency.
Wind and geothermal are the cheapest way to generate electricity, and the private sector is aware of this and is anxious to build facilities so that they can reduce production costs and increase profits.
Now, the electricity is very cheap, so the solar energy can\'t compete with it, which will change in the end.
By the way, oil is not used for power generation (
Less than 1% of total U. S. output)
Therefore, oil prices do not affect electricity prices. Cheaper oil (
Cheap today, who knows tomorrow)
Making solar thermal systems no longer an advantage, but the sun is always free.
Since the coal, gas and oil industries do not pay for pollution, including carbon dioxide, they are free to ride.
Using solar and wind energy, all manufacturing and pollution costs are paid by consumers at the time of purchase.
Taxes began on environmental damage by fossil fuel companies, including mining, air and water pollution, and solar and wind could quickly look economical.
Oh, and the Iraq war?
This is also, to some extent, a free giveaway to support the oil industry.
Several recent advances in solar technology will help the industry rebound: 1)
MIT has developed inexpensive, safe artificial photosynthesis (
Separate water into hydrogen and oxygen)
The \"holy grail\" of the industry \".
This makes it feasible to store energy in backward days and cloudy days.
A research group in Wales has also created similar technologies.
It is speculated that we are still 10 years away from driverless houses on the grid. 2)
Nanotechnology enables the generation of solar panels to capture 96% of the light.
The most efficient group was around 30%. 3)
A new type of solar panel can absorb light and impact the panel even at an angle of tilt.
The old model uses an electric motor (
Powered by the same solar panels)
Adjust the panel throughout the day to point directly to the sun.
Of course, the fuel industry will kill the technology in every way possible, but we can hope, can\'t we?
Every day, more energy from the sun hits the Earth for free, more than we use.
We ran out of our children\'s savings, not to mention their lungs.
This is a great solar calculator calibrated for each state.
Depending on the amount of electricity you are currently using, you will get a return on investment in solar panels. //www.
PhpIf solar manufacturers are subsidized, as we have subsidized the oil industry in the past 100, and we are still subsidizing them and we can buy cheap solar cells.
Yes, solar will be more efficient in the future, but as oil and gas supplies reach record levels, they are tying their backs with one hand.
The economy is currently in a downturn and people are reluctant to spend money to improve housing, which will change.
Stewart, apologize to the idea of subsidizing the solar economy . . . . . . The problem is that coal and oil are busy scaring people and making deals to keep them from falling into the hands of consumers.
The idea that only \"certified\" installers can install solar energy in your home (
As rangerous wrote above)
The taste of oil lobbyists working in the legislature . . . . . . It\'s time to move this country forward!
The problem is that most American families cannot afford solar power systems at all.
No, it doesn\'t have a 15-year return for most Americans.
My electricity bill is about $65 a month (
We are good at saving.
It was $11 in more than 15 years. 700.
I have been interested in solar energy for many years (
Over 25 years. )
After repeated attempts to calculate cost efficiency, costs remain high even with the help of solar power system designers.
In order to rely on solar power, you must first make more changes than just using CF bulbs.
The fridge and any separate freezer are history and you have to use gas (
Natural gas or propane)refrigerator (
16cu ft R/F about $2500)or a Sunfrost (
Very low power consumption, the price of 16 cu ft is about $3000. )
You get rid of the electric water heater-the best is the tank-free gas water heater with the indicator light (
No electricity required to start it)
Or hydraulic ignition.
Then, any and all electric heating is also history.
You use gas to heat (
There is a low pumping blower-probably a DC motor)or wood.
In addition, there are huge washers and dryers outside the door-they are too expensive for such systems.
If your system is big enough (
This means more than the cost listed below)
Able to use combined washing machine-
The dryer cleans and dries everything in one machine and runs at a speed of 110 instead of the 220 required for a traditional washer and dryer.
All of this means average house prices are down at least $9000 or so-you still have to put the system in.
People don\'t just \"Buy the panel and insert it into the house \". ’ You need(1)Panels (
In most parts of the United States, they only work a few hours a day)(2)
Bracket for panel-stand-alone or roof (3)
Charging Controller (
Between panel and #4)(4)Batteries (
Ouch-very expensive and need to be replaced every 5 minutes
15 years depending on the type.
Must be able to store 3-
For up to 3-3 days, use only 30% of the battery capacity5 days. )(5)
System Monitor (
Read battery charge, battery usage and have other functions)(6)Inverter (
Except that the DC appliance and all the appliances in 99 + % are AC, the power generated in the battery and then stored cannot be used directly)(7)
Cabling, cables and connections (8)
If solar energy is used and power grid is used, a special display that can be switched between two power supplies to provide a price tag for a system that produces 5000 KW per day?
Try about $40,000.
Most households use 3 to 5 times a day of electricity, and the use of the above method to compensate for consumption may be reduced to 7000-
8000 if they give up a non-plastic toothbrush
, an electric alarm clock and something like that
The cost of solar water heaters that do not freeze is very high-up to $7000 --10,000.
These prices cannot be paid by families.
The biggest technological leap in the shortest time (1)
Just after World War II. 2)
During and after the 1960 space race
In both cases, government-paid research has created technology and turned it into a service for the people.
For example, the HEPA air purifier running in your corner is from NASA\'s space flight research.
Like computers, the private market is also very slow in creating new technologies.
Private businesses spent 100 changing everything from crafting to using machines (19th century. )
Even so, as technological advances are thought to be so slow, the manufacturing process of the machine will last for decades, so that the machine will be put into use for decades before leaving the factory --
Date of the new device.
Make the same big leap in solar energy and alternative energy
The technology of the Second World War, the government will have to bear the burden of cost.
A lot of research and development has not been successful, and private enterprises are not willing to bear such losses. (
Look at drug research-funded primarily by NIH through grants, not by pharmaceutical companies. )
Current material polysilicon and future materials based on III/V or II/VI compound semiconductors need to be mined, processed and packaged into useful opticalto electrical converters.
This is not an environmental problem.
Instead, seal up carbon dioxide. Sell it.
Add water or hydrogen to it, produce methane, burn methane to generate electricity, collect carbon dioxide, add Watt, and equip your home with a closed cycle generator.
How does Berkeley liberals plug a hydrid car into a methane generator?
At the end of last year, innovative municipal financing developed in Berkeley and Palm Desert in California triggered a global
Financing of solar and energy efficiency, as the benefits to residents, businesses and governments are amazing: * No.
Cutting-edge costs and no credit check * fixed payments for 20 years, costs offset by lower utility bills * payment transferred to new owners invented the popular Berkeley micro when the property was sold
National Solar investment program.
From the success of Berkeley, the Renewable Energy Fund has launched an ambitious plan to extend this model to other parts of the United States.
The company expects that a national plan will provide $280 billion in funding for improvements in solar efficiency and remove significant CO2 pollution each year-at no additional cost to local, state or federal governments.
Look at US:/www. renewfund.
ComI would like to see a secured loan program, such as a student loan program, for the purchase of home solar energy and to retain the tax credit.
Where is the power company cooperative (
Like rural electricity cooperatives)
, Manage loans through regular REC bills. Home-
Power based on solar and wind power does not need to be updated to the grid, so it is much more cost-effective than many think.
Calculate the cost of building a new coal-fired power plant or upgrading the grid to take over the Texas wind power plant. Suddenly home-
More meaningful based on power! To Ann (#20)
: Maybe part of the reason you can\'t get it to work is because the numbers you say don\'t make sense.
First of all, 5000 KW a day is meaningless.
You wrote a power number (
Is an instant)
Not energy (
This is the amount of electricity used for a period of time).
Secondly, 5000 KW of the house is ridiculous and huge.
I guess you made a mistake, meaning you need the power of 5kw.
If so, it\'s still big unless you have a big house or many inefficient appliances.
Most ordinary families do not need more than 2kw of instantaneous power at any time.
Maybe you should study efficiency more carefully before complaining that you can\'t make solar work.
Third, a complete cost (
All items you mentioned minus the battery, see below)
In California at least, the solar system is able to generate 3 KW of AC power, plus a state tax refund and a federal tax credit, at a price of just over $15 k.
Return period: 10-15 years. How do I know?
My parents have just signed a contract to install such a system-there is no cheating here.
Fourth, who says you need a battery?
Do you want to completely disconnect yourself from the grid?
If you\'re in a state like California, there\'s something called the Web.
Metering-you only pay the net amount you get from the grid within a year. Read up on it.
I suggest doing better research, or talking to someone who really knows how all this is combined . . . . . . There are solar farms everywhere in Spain.
The government has been continuously investing and encouraging renewable energy.
