In comparison to conventional hydrocarbon fuels such as coal or oil in generating electricity, the cost of solar energy is significantly higher. In our example, a ton of coal on the average produces approximately 6,182 KWH of electric at a cost of about $36 per short ton (2,000 pounds). In comparison to solar energy, the hydrocarbon fuel costs are significantly lower without rebates, tax benefits nor the cost of carbon emissions.
Some of the considerations for a solar energy system include the 20-to-30 year lifespan of the system and the hours of available sunlight. In order to compare the solar energy costs to conventional hydrocarbon fuels, we must covert the $8.95 per into KWH.
So a $45,000 5KW solar energy system produces about 119,246 KWH of electric over its lifespan meaning the average cost equals $0.38 per KWH. The relatively high solar energy costs in comparison to conventional fuels should improve with utility rebates and government tax incentives. We will explore the some of the advances in thin-film technologies, the declining costs of solar panels, and the improving solar conversion efficiencies that should continue to bring solar energy costs on par with hydrocarbon fuels. I would like kindly ask the cost of solar energy for desalination and and energy generation and the area to be allocated per 0ne MWH solar energy generation.
I have a 3k system on my roof and it produces annually between 4,700 and 4,900 kwh of electricity, so your calculations are clearly understating the kwh generation of better systems on well-oriented roofs (my panels are Suntech). But let’s assume I get 25 years at original efficiency and only another 10 years at 90% efficiency.
Note that by putting a solar system on my roof I have LOCKED IN the price per kwh of 4.4 cents per watt for the next 40 years. As for the stated price of coal per khw in this article, this is meaningless to a homeowner. Oh, and this return is entirely TAX FREE because it represents a savings of a necessary expense and not interest or dividend income from Mr. Secondly, the machine it uses for this, an ion implant machine, also cuts equipment needs, eliminating the need for a handful of machines or tools often used in this process. So, it is with this double-impact that Twin Creeks says it can achieve the cost reductions discussed above.

To further explain why Krugman is simply ignoring reality, check out this excellent post from Todd Myers of the Washington Policy Center (our sister think tank in Washington State).
Meanwhile, even the International Energy Agency, no friend of renewables, is forced to admit that renewable energy prices are becoming cost-competitive with fossil fuels. Unfortunately, the United States is far behind countries like China, Brazil and Germany when it comes to renewable energy. The International Energy Agency has included hydroelectric power in its renewable energy market basket in order to make the cost per kwh of renewable energy competitive with coal and nuclear. The numbers in the bar chart above may be a factor of two high for PV and quite low for the fossil fuels, but Krugman is just wrong on this. It is completely ironic that a technology comes along that liberates the individual from dependency on centralized electricity generation, yet must face the wrath of the libertarian movement.
It does make sense if you understand that unfettered capitalism will degrade itself into defending its previous capital expenditures at the cost of its own future viability. In a world that is not spending all of its creative talent defending obsolete capital expenditures, individuals using the sun for their needs would make total sense to the real libertarian. I am all for people using whatever solar power (or wind, or whatever) they want for their own personal power generation. The would-be free market is already distorted by government subsidies, import dumping, investor owned monopolies, and the right to pollute at no cost to the polluter.
When government creates and sanctions a monopoly and sticks it right in the middle of commerce, this is a subsidy, a market distorting subsidy.
It will be difficult for free-marketers to avoid calling externality measurement and allocation a form of regulation to be eliminated. Subtract from that the poor efficency (higer effenciencies are obtained by using larger collectors and focusing to a smaller area like a mignifing glass but remember the 2 kw per meter limit), cloudy days, night, and the inefficiencies of storage systems (for cloudy days and night) and high maintenance (like a dirty window a dirty solar panel face is less light to be converted) and solar equates to poor power conversion. Depends on how much power you consume as well, some people sell power back on to the grid too.


Yes, don’t confuse me with charts or graphs showing how much of the burden for YOUR solar is being paid by WE the taxpayer! The Rio Grande Foundation is a 501c3 non-profit organization and your donation is tax deductible. Many homeowners, when they start their solar journey, hit the same roadblock early on: determining the cost of solar panels. The total cost of installation includes equipment, labor and "soft costs." Solar equipment prices have been going down significantly in the last few years, but other cost items remain stubbornly high.
The cost per watt metric is nothing but a handy way to "normalize" the total cost of installation. Because the cost per watt varies from country to country and from state to state, it's always a good idea to find out the average cost of installation in your area. The cost per watt metric is a great start to assessing the financial aspects of solar ownership, but we have a bit more work before we can safely conclude the cost discussion. The levelized cost of energy is essentially the entire operating cost of your solar pv system. Levelized cost is such an important metric that it is in fact a key factor in deciding whether solar energy will save you money: to answer that question, you need to compare the LCOE of solar to the retail electricity rate from your utility. The last slide (Conclusions) sums it up quite nicely: even if the reliability figures are comparable, you only risk a single panel when a micro inverter fails. Although you don’t really go on to say how good of an investment solar energy actually is, in the long run. You are not considering the cost of pollution and environmental degradation related to fossil fuels (coal, oil and gas) energy.
Twin Creeks’ new technology and manufacturing process can reportedly cut the manufacturing cost of solar panels in half! Clearly, if Twin Creeks’ claims are true, its manufacturing equipment could be revolutionary. He has been covering green news of various sorts since 2008, and he has been especially focused on solar energy, electric vehicles, and wind energy since 2009. Opinions and comments published on this site may not be sanctioned by, and do not necessarily represent the views of Sustainable Enterprises Media, Inc., its owners, sponsors, affiliates, or subsidiaries. This explains our local electric monopoly fighting to keep its old polluting coal fired power plants running despite the damage this policy does to utility’s own future.
And, unless you are completely off the grid, you benefit from the grid which is paid for by the rest of us utility rate payers.
Solar energy is very beneficial, and if this person would rather pollute the earth with fossil fuels, they don’t deserve to live here.
We do not accept any government funding; our funding comes from private donations from individuals, corporations and foundations and every dollar counts.
They hear about all sorts of benefits of solar power, such as lower utility bills, abundant clean electricity and vastly reduced greenhouse gas emissions.
We'll first cover the concept of cost per watt and then introduce you to another cost metric (lovingly called the LCOE - levelized cost of energy) that is crucial in making sense of solar economics. The term "soft costs" is a blanket category that includes permitting fees, marketing expenses, taxes and other miscellaneous costs. This figure is based on data reported from Arizona, California, Massachusetts, and New York. The reduction in solar panel equipment prices (as shown in the bottom curve in the graph) definitely helped with this overall trend. It used to be quite difficult to get this kind of information, but a recent initiative has made it much simpler: the Open PV project. If you are thinking of owning the solar pv system (as opposed to leasing it), then your total cost of ownership will also include maintenance and the eventual replacement cost for the inverter. It includes the initial installation cost, cost of financing, cost of replacement inverter and maintenance and most importantly, it's based on the expected energy generation specific to your location. Indeed, micro inverter manufacturers promote a longer expected life time as a major selling point.
At the end of the day, it boils down to the economics of solar: if you get a great deal with a string inverter, you can still come out ahead. The most common type of solar modules (or panels) is now down below $1 per watt, on average.
It thinks its equipment and process can get the cost of solar panels down to $0.40 per watt. How a company treats its shareholders versus its customers shouldn’t need regulation (but it apparently does). But as soon as they take the next step and seriously look into the financial viability of going solar, the confusion begins.


So if you hear someone mention that their "solar panel cost per watt" is $4 per watt, they probably mean the whole cost of installation, not just the panels. In fact, today, the main cost challenge is not about the solar panels themselves, but with the remaining cost items. The solar panels generally come with a 20-25 year warranty, and with no moving parts, they should be low maintenance, consisting of an occasional cleaning.
We say this often, when it comes to solar energy, it's all about location, location, location. For more information on the levelized cost of energy, we've written another article that can be helpful.
We know that all this information may be a bit too much to digest if you're just starting on your solar adventure. Regarding your point in changing the inverter in less than 10 years, I am looking at Emphase M250 Micro Inverters, they are good for 25 years apparently. So multiply the cost per KWH number for solar some 2-3 times to get more realistic picture.
As I stated above, solar power is experiencing serious price drops and growth, but if all this is true…. Investor owned monopolies actually assist high-cost renewables because they don’t have to compete on price. I’m not saying that this is a total non-issue, but existing non-renewable fuel sources are already regulated heavily in terms of pollution. Pollution requires regulation because it brings harm to all, not just to the parties to the transaction. Finding a simple and unbiased answer to even the most basic cost-related question, such as "How much will it cost me to have these panels installed?" can be frustratingly difficult. After 2019, the ITC will be gradually phased out over three years until it is completely eliminated after 2022. However, the inverter will need to be replaced at around the 7-10 year mark of the lifetime of your system. In this case, the higher the insolation levels, the lower the levelized cost will be (all other variables remaining the same).
And to see what the average levelized cost of solar is by state, you can refer to our interactive grid parity map.
Even if I must refresh in 10 years, my calculation indicates I will have pay the system in 6-7 years, with the possibility in making positive value for 4 years (crossing my fingers). Solar at this time is completely lacking any commercial viability for most people and businesses. We just need to notice that is not okay to sacrifice everyone’s health for cheap electricity. The "Wp" stands for watt-peak, another way to indicate the installed capacity of a solar pv system. A ballpark figure for the inverter replacement + maintenance cost is 10-20% of the installation cost. You can head to Sunmetrix Discover to see the impact of these cost metrics for your own home. Thus, if you are considering a $20K system, you should factor in another $2000 - $4000 in future costs. Don't worry about any complicated calculations, we've already done the heavy lifting for you. Therefore, we strongly recommend you to look up the latest average cost figures in your own state before getting your quotes.
Both Bob and Sue received quotes for a 5 kW solar PV system for their homes (with exactly the same solar PV equipment). Both quotes come with a price tag of $20K (so $4 per watt when it comes to the cost per watt metric).
The only difference is the location: Sue is luckier as a result of her more southerly location. Due to higher insolation levels, she will produce more solar electricity over the lifetime of her panels, and as a consequence, the levelized cost of her solar PV system will be lower.
