The current data point to three main obstacles in the adoption of solar energy.
Cost
The cost of solar is down to just 10 percent of what it was five years ago. But for solar to be viable without government subsidies (like the ones driving Japan's solar boom), the price per megawatt-hour will have to keep sinking. Solar still costs $156.90 per megawatt-hour, more expensive than coal at $99.60 per megawatt-hour, and natural gas at $65.50 to $132 per megawatt-hour, according to the U.S. Department of Energy.
Materials like cadmium telluride, a crystalline compound used to make thin film solar cells, have helped drive down the price. These thin film cells can be manufactured much more quickly and inexpensively than silicon-based technologies, and they collect more energy, reaching 18.7 percent efficiency — well above current commercial cadmium telluride modules, which reach between 10 percent and 13.1 percent efficiency.
Infrastructure
Integrating new solar energy into existing energy grids poses many challenges, according to a recent study in the Journal of Renewable and Sustainable Energy. The current generators allow utility plants to balance the amount of energy generated with the amount used. But with solar cells, the amount of energy generated is sensitive to environmental changes, like the passing of a cloud, which can reduce electrical output by 50 percent within just a few seconds. Fixing this problem could prove quite expensive.
To compensate for solar power fluctuations, engineers currently incorporate fast but relatively expensive generators that perform frequency regulation services. These generators inject extra power into networks when fluctuations in photovoltaic output cause the generated electricity to dip below the desired frequency of 60 Hertz.
The use of solar power cannot be increased without also increasing existing frequency regulation services. This will increase the cost of solar electricity, which is already much higher than other sources,
Some experts predict that without increasing the number of frequency regulation generators in use, solar power won't be able to supply more than 5 percent of our current power demands.
Night
The hours when demand for energy is at its highest are the same hours the sun is totally absent. Scientists have devoted a lot of effort to figuring out how to store solar energy to use at night. One option is solar batteries, which are effective, but can cost as much as $6,500 per household.
Another system, currently the most common, uses thermal power plants to store heat in molten salt, oil, or beds of packed rocks at scorched temperatures to be used later.
A new method developed by the University of Arkansas uses a structured thermocline system in which there are parallel plates of concrete with steel pipes running through them. These steel pipes transfer heat absorbed by solar panels into the concrete, which stores it until it is needed to boil water and produce steam, or supply heat to other heat-powered generators such as Stirling engines or thermoelectric modules.

Tekonline.org,
Thanks for the comment.
Our cost data point are as well valid!
You appear to argue as if governments are not subsidizing existing systems, that solar must self-sustain.
Even the US subsidizes VRA/Hoover Dam in the Tennessee State/Region. (We could provide a lot more points on that one, and subsidies in general).
Further, we imagine cost in Ghana would be a lot less than the data point(s) from the US Energy department show.
In addition, the load put on national/regional grids in the Ghana by households, are not any where comparable to loads in Ghana. In other words, while you may need $6,500 battery to power just one household, in Ghana, you could power a lot more households with the same system.
If you will notice, this time, we discuss industrial scale solar power systems, where there are a lot greater economies of scale, factoring cost for gas to power thermal plants that depreciate and have many other disadvantages, other than cost of even fuel.
Our example from India ought to be instructive!
Thanks so much for your comment.

Prof, I was dumbstruck by your facts of the cost of solar plants- $1m per MW approx. I was dumbstruck not because of the cost per se, but, because our visionless, clueless leadership haven't adopted solar to any significant extent, given the cost involved. These idiots can go on the bond markets & raise billions, for what? Yet that same billion dollars can get us 1000MW, which, would go a long way to alleviate our energy problems and, save us foreign exchange in the future, forever. These neo-colonialists running Ghana are only interested in their pockets and are totally devoid of altruism.

You see, you do not know anything about us, except by these essays.
Further, one does not even have to live in Ghana 12-Months-A-Year to "help fix the problem", the way you "see" it.
So trust us!
We are also contributing, probably a lot more than many people who are in Ghana 12-Months-A-Year.
With respect to some of the persons you identify, to "...follow these hereos like , Paa Kwesi Ndom, Kwame Pianim, Dr Bawumia,KSM,Dr Frimpong Boateng Dr Kwesi Botwe...", we congratulate them on their success, if the success was achieve legally, and not through rigged government contracts, nepotism, and plain theft and "robbery" of government resources.
ITEM:
1. We believe that many people have questions about how "Paa Kwesi Nd(u)om" acquired his wealth. (That is no secret today).
2. We understand that "Dr Bawumia" is an economist. We recently obtained a copy of his Power Point brief making a case for a "New Voters' Register". We have reviewed that paper expect to have our response published on these same pager in a day, or two. (So, hold tight and write back, after you read our Report on his request).
3. We do not recall ever heard mentioned the names of the other persons you give as examples of the Gone-Homers!
Still regarding the "Gone-Homers, please read comments below (from Non-Politician).

Again, you are still assuming a lot about us you do not know!
ITEM: There are many stories of people who, immediately after earning a degree or two, went back to Ghana (Africa), were appointed as very high level officials, and did not have any idea what administration is all about. In other words, they did not acquire competent skills and training in their area of study before leaving.
Then there are those Non-Politician" talks about, still!
YOUR: "...i mentioned found out that if you dont belong to any group in ghana your voice or contribution is useless so thats why those chose a political platform to help , and this is simple, in america uk nigeria, togo, france etc one cannot be a financial expert,energy etc and live else where outside the country and tell obama or angela that do this do that without the rep,dem,ldps udc and it will be done ,...how many people in ghana have access to 15mbh internet if iam right all your work and campaign is on the internet..."
WE SAY: No! In this case, to your last point, you are not "right"!
Funny, your understanding!
The last time we were in a discussion with some colleagues, there was some information about the dependence of the Government on private consultants.
Knowing all that you know, maybe it is time to ask Dr. Bawumia why saind he want a "new voters' register" that "...should be independently audited by an internationally reputable firm...".
QUESTION: Do you know if there are any such "firms" in Ghana at this point?
ITEM: Belonging to a political party because the party members are mainly from your town or group, without caring about policy, is the biggest problem, next to theft of government resources, by political parties (and their members).
And if, Ghanaians cannot learn from other countries simply because all advise and information must come from inside Ghana, then Ghana really has a long road to travel. (But that is not how the journey began in 1957).
If our last point is the case, maybe Ghanaians do not need all the remittances by people living and working in Ghana, nor even travel by those people to Ghana any time of the year!
Finally, the question for the people with degree(s) from outside Ghana becomes what quality, and how long must be the acquisition of core competencies, skills, and training in their area of study, after the degree(s). That explains in part why in "obama or angela" USA and Germany, they value strongly the contributions of retirees to national, state, regional, district, local, etc., development and life.
kwame bee, our current essay is about renewable energy and you chose to start you comment with that subject line. Still, we thought we would address your initial comment and the follow-up because our next couple of essays address certain aspects of the problem.

Namibia shelves its long-term energy solution
By News Ghana -
The future of Namibia’s 41-year-old gas dream hangs in the balance after the finance minister announced last week that the project will empty state coffers.
Namibia
The Kudu Gas Project, expected to produce about 800MW upon its commissioning end of 2017, was going to be the only Combined Cycle Gas Turbine plant in the region.
In March this year, the project was costed at 14,4 billion Namibian dollars (about 1.2 billion U.S. dollars at the time), but this has since gone up to about 35 billion Namibian dollars (2.5 billion U.S. dollars).
Plans were that a gas power station would be built near the gas fields at the southern town of Oranjemund about 800 kilometers from the capital Windhoek.
Construction was expected to start in the first quarter of 2015, while the implementation and commissioning had been scheduled for the end of 2017 or the first quarter of 2018 latest.
But finance minister Calle Schlettwein’s admission to the media that the Kudu Gas Project could suck state coffers dry puts the dream into another deep slumber.
On his change of heart, Schlettwein said he had to assess the country’s finances and the risks the Kudu Gas Project will have on the economy.
“I have a worry that the Kudu Gas Project will use up the total fiscal space Namibia has and the country will not have the ability to raise any more funds for other projects,” Schlettwein said.

Undoubtedly, the cost of solar will fall as demand increases, but, the huge lobbying power of the big oil companies will ensure that solar struggles to establish itself, significantly. In the long term, solar is cheaper.

April 23 (Bloomberg) -- More than half the U.S. states with laws requiring utilities to buy renewable energy are considering ways to pare back those mandates after a plunge in natural gas prices brought on by technology that boosted supply.
Sixteen of the 29 states with renewable portfolio standards are considering legislation that would reduce the need for wind and solar power, according to researchers backed by the U.S. Energy Department. North Carolina lawmakers may be among the first to move, followed by Colorado and Connecticut.
The efforts could benefit U.S. utilities such as Duke Energy Corp. and PG&E Corp. as well as Exxon Mobil Corp., the biggest U.S. oil producer, and Peabody Energy Corp., the largest U.S. coal mining company. Those companies contributed to at least one of the lobby groups pushing the change, according to the Center for Media and Democracy, a Madison, Wisconsin-based non-profit group. It would hurt wind turbine maker Vestas Wind Systems A/S and First Solar Inc., which develops solar farms.
“We’re opposed to these mandates, and 2013 will be the most active year ever in terms of efforts to repeal them,” said Todd Wynn, task force director for energy of the American Legislative Exchange Council, or Alec, a lobby group pushing for the change. “Natural gas is a clean fuel, and regulators and policy makers are seeing how it’s much more affordable than renewable energy.”
Conference Discussion
President Jack Gerard of the American Petroleum Institute, a trade group for the oil and gas industry, along with the former governors of Colorado and New Mexico will speak about the issue today in New York at a conference hosted by Bloomberg New Energy Finance.
Hydraulic-fracturing technology opened aging reservoirs for natural gas drilling, driving prices down about 72 percent from their record 2005 high. That’s making more expensive wind and solar power projects harder for utility regulators to justify, according to Alec and its allies, which include the Heritage Foundation in Washington.
“The shale revolutions are not just having ramifactions politically and economicaly in the U.S. but also around the world,” said Michael Liebreich, chief executive officer of Bloomberg New Energy Finance. “In 17 years, not that far away, we could reach peak energy use. This is not generally accepted.”
Threat to Wind
Killing support for renewable-energy policies threatens sales at companies from wind-turbine makers General Electric Co. and Siemens AG to SolarCity Corp., the San Mateo, California-based rooftop energy developer.
The push at the state level replicates efforts in Washington. Opposition from Republican lawmakers delayed the extension of a federal tax credit for wind power, prompting Vestas, the biggest turbine maker after GE, to fire 10 percent of its workforce at two Colorado factories.
“There haven’t been any outright repeals yet, but we’ve seen some watering-down,” said Justin Barnes, senior policy analyst at the North Carolina Solar Center. “Activity against renewable portfolio standards has been increasing in the past year. Their arguments are mostly on cost.”
The Raleigh, North Carolina-based research group is supported by the Energy Department and operates the DSIRE database of state incentives.
U.S. Renewables
U.S. investment in renewable power and energy efficiency fell 54 percent last year to $4.5 billion as government support waned, according to data compiled by Bloomberg. The level may slip again this year if states dilute their requirements, which have pushed utilities to contract power from renewable providers and scale-back use of coal- and natural gas-fired generation.
Alec wants to repeal state mandates, arguing that the free market is a better way to determine the most cost-effective source of power, Wynn said. It typically drafts model legislation for state lawmakers to use as a blueprint when drafting bills, including the Electricity Freedom Act, which was published in October.
The anti-renewable mandate effort is also fueled by the Heartland Institute, the lobby group that’s pushing to repeal clean-energy goals that it says increase power prices, cost jobs and do little to improve the environment, according to Heartland’s website. Officials from the organization weren’t available for comment.
North Carolina
North Carolina’s renewable requirements will cost state ratepayers as much as $1.8 billion from 2008 to 2021, the Heartland Institute said in an April 2 policy statement, citing a report from the John Locke Foundation and Beacon Hill Institute.
Repealing the state’s RPS policy “would help increase disposable income, attract more business investment and make energy more affordable for consumers,” according to the statement.
A Heritage Foundation spokesman referred questions to Alec.
“We expect in the next year or two that state-based incentives will disappear,” said SolarCity Chief Executive Officer Lyndon Rive. “Whenever you see the effort, peel the onion and find out who’s behind it, who’s funding the effort. It’s very annoying that people can get away with the shell efforts and call it the people’s voice when it’s funded by coal.”
Legislative Debate
North Carolina lawmakers began debating this month a bill that would cap utilities’ required purchases of renewable energy at 6 percent of demand in 2015, half the current target, and eliminate the requirement in 2021.
“North Carolina is leading the nation in protecting consumers from the mandates for high-cost energy,” Wynn said in an interview. “It will show other states how to follow suit.” North Carolina’s bill revises the targets in the existing 2007 law and isn’t based on Alec’s template legislation.
A House committee already approved it and General Assembly Majority Whip Mike Hager, who introduced the legislation in March, said he expects it will pass this year.
“We could never have imagined in 2007 such an abundance of domestic natural gas,” Hager said in an interview. “We need that Marcellus shale gas to offset the high cost of renewables and prevent electricity prices from rising further. It’s like raising children: they need to grow up learn to live in the real world.”
Republican Push
Hager is a Republican whose top campaign donors include Duke Energy and the Charlotte, North Carolina-based utility owner’s Progress Energy unit, according to the National Institute on Money in State Politics, a Helena, Montana-based non-profit group. He expects the bill to pass through the GOP-controlled legislature, and that Governor Pat McCrory, also a Republican, will sign it.
Duke hasn’t taken a position on the North Carolina bill, said Jeff Brooks, a spokesman who confirmed the company has supported Alec.
Colorado’s state senate passed a bill April 16 that would increase the amount of energy utilities must get from renewable sources, and also expands the definition to include non-renewable sources such as methane produced from coal mining.
Connecticut is following a similar strategy, by including large hydroelectric plants in its definition of renewable energy. That will help utilities meet the state’s goal of 20 percent renewable energy by 2020, said Nick Culver, an analyst at New Energy Finance in New York.
“Connecticut has thrown up the white flag on its ambitious renewable targets, and is now negotiating its terms of surrender,” Culver said. “Instead of simply easing back targets, they intend to widen eligibility criteria to include imported hydropower from Canada that would have been built regardless, which amounts to pretty much the same thing.”
Proposed Bills
Other states considering similar policies include Missouri, Ohio and Kansas. Thirty of the proposed bills in those states were deemed “significant,” meaning they have the potential to affect demand for renewable power, by the North Carolina Solar Center, a partnership between the Energy Department and North Carolina State University that tracks such activity for the U.S. Energy Department.
Alec’s Wynn said groups in six additional states are planning attacks on renewable-energy policies.
The wind and solar industries are beating back efforts to reduce demand with their own lobbying, said Carrie Hitt, vice president of state affairs at the Washington-based Solar Energy Industry Association.
“This is a deliberate campaign by conservative think-tanks, the Heartland Institute and Alec to overturn renewable energy policy that threatens the fossil industry,” Hitt said in an interview.

We certainly have to do something to end the embarrassing dumsor-dumsor. Our govt. must provide leadership to create the enabling framework in the energy sector. Mahama's administration has to speed up investing in renewable technologies, especially, off-grid & mini-grid to generate electricity in remote areas of Ghana. Jatropha farms to produce biofuels, wind turbines in littoral Ghana & geothermals in mountainous areas like Shai Hill, Afadzato mountain & Odwamena in Kwahu Ridge.
We can make a difference, working together !

No MARCUS AMPADU,
This essay among others were pulled behind he curtain a bit earlier than Ghanaweb normally does.
But, thanks for the link to that document. We believe that there are enough resources with respect to knowledge to allow any serious government to initiate a solar power program in short order.
But they must be serious to move away from coal and gas, while their countries are still located on the Equator.
Although there are some programming issues, from the document, "...IRENA’s Regional Action Agenda calls for country and regional-level planning to consider renewable power options, on account of their declining costs, energy security, and environmental and socioeconomic benefits..."
WE SAY: Precisely!
READ: "...Ghana’s forest cover has declined by more than 75% since the country gained independence in 1957, according to a report in the Accra Mail. Ghana’s Forestry Minister, Esther Obeng Dapaah, told the annual general meeting of the Ghana Timber Association that forest cover in the country now stood at below 2 Mha, compared to 8 Mha 50 years ago. Dapaah said that over-logging, by both illegal operators and contracted companies; the expansion of industry; conversion of forest into agricultural land; and other land use changes had driven the decline..."
We believe among the problem is the issue of fire-wood, erosion, and loss of plant nutrients, wit effects for animals and wild life, etc.
So, if we have solar power for energy, we can use the gas we find/buy to cook, and in the process save trees from "fire-wood", and help preserve/grow forests!
Again, thanks for the link!

Photovoltaic solar cells can made with 3D printers and these cells can be soldered to form solar panels with instruction videos freely available on the internet. There are also solar collector systems whereby electricity can be generated indirectly with a steam turbine by using the heat of the sun to turn water into steam either with concentrating solar collectors or with the regular solar collectors. All these things can be produced in Ghana, it's just a matter of political will or a matter of policymakers with backbones refusing bribes etc. by coal and oil company lobbyists.
