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.

Rising inventory levels of photovoltaic (PV) panels and new production capacity coming online is driving solar PV prices lower and thereby, bringing solar energy closer to grid price parity. To get a better perspective on the solar PV industry, let’s examine inventory levels for some of the leading solar PV suppliers.
While it is important to control inventory levels in relationship to sales, revenue growth is predicated upon price, performance, and return on investment for prospective customers. In Figure 2 Green Econometrics is comparing the market value of some of the leading PV suppliers as measured by their respective stock prices. There appears to be a lot riding on the success of thin-film PV and as prices fall for crystalline PV, the closer we get to grid parity. The bottom line is that despite the lower PV panel costs; we are still not at parity with hydrocarbon fuels such as coal and oil. The following charts on solar panel cost trends and solar power growth trends are fun, and good for a share, since many people are completely unaware of these trends. Of course, to get a very specific cost of solar panels estimate for your own home, you can just spend about 60 seconds answering a few question at the link above and we can hook you up with this in a jiffy. Well, that basically tells you everything you need to know right there — the cost of solar panels in 2013 was about 100 times lower than the cost of solar panels in 1977 (even more than 100 times lower!) — but I promised 10 charts, so let’s dig in even further and throw on some other fun charts and graphs. Of course, as you can see in that graph above, the cost of solar is headed towards the wholesale cost of electricity from natural gas… which would actually get utility companies and power plant developers switching to solar in a big way.
The lesson is: the cost of solar panels has fallen off a cliff, and that means that solar power now crushes electricity from the grid for a huge number of people.

Good article but slanted in the sense that there’s no mention of ongoing maintenance on panels or deterioration of solar panels over time nor the life expectancy of panels exposed to sun, rain, ice, snow and bird droppings. This is all great news, and no one wants solar to completely replace fossil fuels more than I do, but the numbers to achieve that goal are daunting. So I tried exponential growth to the 50% level which is when the growth starts tapering off using the logistic eqn.
First Solar (thin film) has stated that they expected their costs to drop to the mid-thirty cent range by 2017. So look to Utilities to keep their future Utility Energy costs just slightly above the cost of adding solar to one roof, since that will maximize Utility profits and minimize the number of ratepayers that install their own Solar!
I hope a future president will come forward and challenge the power companies as well as invest more taxpayer monies into solar and other renewable energy.
Very important article.Note remarkable Hawaii situation on charts,BUT,difficulty obtaining utility interconnect here.Public Utility Commission pressure is being applied,while PV customers wait! Yeah, everything should be even better, but I haven’t seen comparable graphs for more recent years.
According to the headline, there must be at least two tons of charts, so these weigh at least 285.714 lbs a piece. I can very easily answer the question “How much do solar panels cost?” (see below), but I think the real question you’re asking is “How much will it cost to put solar panels on my roof?” That’s a more complicated question to answer, but I’ll explain in more detail and provide some useful perspective on that in the article below. When you ask, “How much do solar panels cost?,” what I think you really want to know is how much it costs to put solar panels on your roof, right? The bulk of the price of going solar is now the “soft costs” (installation, permitting, etc.) rather than the solar panel cost. The total price of a system, of course, varies tremendously based on the size of your roof and your electricity needs as well. So, the key is really just to get an initial quote and then get a closer look at your situation from a local installer, who can give you a more specific quote.
But when it comes down to it, what you probably really need to know is how much it will cost you to actually go solar. In many places, you can now go solar for $0 or close to $0 down through solar leasing companies or through simple bank loans, the latter of which would generally be my preference. Studies have found that the average solar homeowner will save about $20,000 over 20 years from going solar.
Furthermore, solar panels are likely to pump out electricity to a similar degree as when new for well over 30 years, perhaps even well over 40 years. But, again, the financing options and the savings really depend on where you live and some personal circumstances (like how much you’re spending on electricity right now). For a little more of a look at how prices and savings can vary by state, below is an infographic based on 2011 research. I hope that infographic and article helps you in considering the many factors at play that influence the cost of solar power. It is interesting to see that the maps hardly reflect the differences in available solar irradiation. Indeed it is worth switching to solar panels for saving money in the future .Although it will cost you a lot when you buy,the fact that a electric consumption is much lesser cost that you can benefit for about 20 -25 years. Yes, its true that last few years have seen a considerable amount of reduction in the prices of the solar panels which has made the solar roof top technology a feasible option for the people in America. With a ten year payoff and a 30, 40 or more lifespan solar will save buyers a heck of a lot of money. Hypocritical trolling from someone who frequents Brietbart, Glen Beck and other ultra-right wing political sites.
Someone with the initial capital is invite me to produce solar panel, what are you recommendations?
Are you talking about buying just solar panels or you talking about an installed solar system? So I would consider possibility of trying to maximize the size of the system; or at least not be limited by usage as the ceiling. Best if we each generate just enough to meet our needs when balanced out with a battery system to draw down in inclement weather. The chart at the left shows the yearly average cost of electricity for 2015 by consumer group per the EIA (the US Energy Information Administration).
Electricity prices vary by location due to type of power plants, cost of fuels, fuel transportation costs and state pricing regulations.
In 2014 the US average residential household used 911 kWh per month and the average monthly electricity bill was $114 before taxes and fees.
As shown in the chart at the left, photovoltaic (PV) solar cell prices have come down by a factor of 100 over the last 38 years; and down by a factor of 25 over the last 15 years.


Since costs after installation are minimal for solar electricity, the relevant costs are the purchase price, installation costs, and the cost of land (capital costs). In the southwest, installed residential solar prices are competitive with residential electricity prices after incentives. As can be seen from the graph at the left, recent solar module prices have experienced a dramatic price reduction. The main reason crystalline silicon module prices dropped so much was because the price of the raw material polysilicon, which makes up a very significant part of the total cost, dropped so tremendously. In addition to the polysilicon issue, the decline is also being driven by a) the increasing efficiency of solar cells (ratio of electrical energy produced to sunshine energy) b) dramatic manufacturing technology improvements, c) economies of scale and d) intense competition which lead to module oversupply.
In 2009 the California Energy Commission (CEC) rejected a contract for a new peaker in San Diego in favor of a PV solar system. The following table shows the Levelized Cost Of Energy (LCOE) for various sources of electricity. Note: CCS stands for Carbon Control and Storage (Sequestration) in a remote underground location.
Nuclear has many sideline issues besides cost and therefore very few new nuclear facilities are expected.
When we say that PV will eventually be at parity with natural gas and coal, that does not mean there will not be any coal or natural gas generators thereafter. In addition, more than 20% of solar and wind would require major investments in transmission lines. Once installed, PV systems need very little maintenance so that the total lifetime cost is mostly just the initial price of the equipment and land.
As shown in the learning curve chart above, cadmium telluride thin film panels are inherently cheaper to make than crystalline panels.
However, the extreme polysilicone price decline is most likely behind us and future price reductions will probably be more modest. A roof top solar system has no moving parts, so it has a long expected lifetime exceeding 25 years (used in this example).
Land related costs which depend on the number of panels, site preparation and security protection.
The value of the electricity produced over the total life cycle of the system is calculated by estimating the initial annual production, called Peak Capacity, and then discounting it for future years based on previously observed annual degradation rates for the particular technology of the site.
There are many different ways to finance a new solar photovoltaic (PV) installation, with outright ownership and solar leasing being the two most popular. Let’s look at the pros and cons of each approach – and then discuss which option makes the most sense for you. 10 years ago, very few homeowners could afford to fully cover their solar installations out of pocket. The main downside of outright ownership is that you’re 100% responsible for financing your system – including installation and maintenance. Power purchase agreements (PPAs) and solar leases are relatively new financing options in which a 3rd party fully covers the cost of installing your solar panels — and charges you only for the clean energy that this system generates. In most cases, this new “electricity” rate is lower than what you currently pay your local utility company.
The key benefit of solar leases and PPAs are simple — you pay $0 for installation or maintenance. The downside is that you don’t receive any of the incentives that outright ownership brings.
What you should realize, however, is that about 97% of Americans grossly overestimate the true cost of going solar – sometimes by as much as $20k. 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. What is really important is that the cost of electricity from solar panels is now lower than the cost of retail electricity for most people.
That means that people like you and me (if we have a roof) can cut our electricity costs by putting solar panels on our roofs! Are you interested in seeing how the cost of solar panels compares to the cost of its main competitor? Are you interested in seeing how much solar panels save the average American who goes solar … or the average person in sunny states like California, Florida, New York, Texas, Hawaii, and so on? So, with all of this information on the drop in the cost of solar panels and the cost of solar-generated electricity, you’re probably thinking that solar power project growth should be going through the roof by now, right? If you have a roof and don’t have solar panels on it, stop wasting your time and see what the cost of solar is and how much you can save right now! After years of covering solar and EVs, he simply had a lot of faith in these companies and felt like they were good companies to invest in. First Solar’s thin-film solar has, and some high-efficiency products from SunPower have. So would be better to keep (1) and add a (1a), that starts at 2000 and resizes vertical axis to see continued progress. If you calculate savings over the warranted life span of the system – most systems are 25-30 year warranties (meaning the panels will not dip below 80% their rated value).
Solar is a great idea for many people, not only to cut their utility bills but also to reduce their dependence on their utility, while also cutting their own personal footprint. There’s tremendous variation in the cost of solar panels based on the type and efficiency of the solar panels. In three of the four most populous states in the country, that 20-year total is actually $30,000. In Hawaii, it’s up above $60,000! Moreover, incentives and the rebates offered by the federal and the state government have made the solar technology actually a lucrative option for the residents. If you took oil in the first years of development or any other new technology it would also show unfavorably. The power exported paid for all the power we bought, plus more than half the fixed $1 per day ripoff fee to utility Co hits us with. Things have changed since then, but the article is popping up on my news feed as if it were current. Prices are higher for residential and commercial customers than industrial customers because it costs more to distribute the electricity and step the voltages down.
The site consists of ten generators, and all ten can be on the grid within 10 minutes generating 450 MW of power. These are intermediate size plants that are normally turned off at night but follow the increasing electrical load as the day progresses. These are nuclear and coal type plants that are very efficient but can take many hours or even days, in the case of nuclear, to come up to speed and to shut down. The total US electricity market in 2014 was 4,093 million kilo-watt hours (m-kWh) according to US EIA. Unless there are unusual circumstances, there probably will be no more peakers approved in California. And, as mentioned previously, it is highly unlikely that any new peaker gas systems will be installed anywhere in the US.
Geothermal, hydro-electric, and biomass are not mainstream electrical production facilities, a few here and there.
Because the sun shines only during daylight hours, and wind is most prevalent at night, both are variable. Not only are transmission lines expensive, but they are hard to permit because of the NIMBY (not-in-my-back-yard) factor. However inverters (which convert the panel DC current into AC) have an expected lifetime of 10 to 15 years. Actual costs will depend on the exact location of the home, the angle to the sun (north-south vs. The LCOE approach allows different technologies to be compared, not only solar approaches, but fossil fuels and nuclear as well.
Every year, panel manufacturers continue to push energy efficiency rates higher, making it easier for solar installations to generate handsome electricity bill savings for owners. In the past 5 years alone, solar panel costs have plummeted by more than 80% due to economies of scale and increased international competition (and have dropped 100 times over since 1977).
There exist a range of federal, state, and utility incentives designed to boost solar PV adoption.
If you consume 1 kilowatt-hour of utility electricity but feed 1 kilowatt-hour of solar electricity, your “net” energy bill is $0.
With a feed-in tariff, it’s possible to generate positive cash flow from your solar panels.


Even with bank loans, the cost of installing solar panels is still beyond reach of some families and businesses.
And that rate is locked in for a set period of time, meaning it won’t change even if the utility company increases its electricity prices. The 3rd party system owner handles all of this — and you merely “lease” the installation. They feel that their budgets are not large enough to fully cover the cost of installing solar panels, so they immediately go for the solar lease of PPA.
Even with a modest budget, it often makes more financial sense to pursue outright ownership.
After an on-site inspection and careful analysis of your electricity bill, your solar contractor can recommend the best financing option for your property and budget.
Stay up to date on the latest news, ask questions, or just see what others interested in solar energy are saying.
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. This is why major companies like Walmart, IKEA, Google, Apple, Facebook, Costco, Kohl’s, Macy’s, Staples, and many others are starting to go solar in a big way. I imagine more efficiency improvements will come sporadically in the coming years, while costs continue to fall. However, the type of panels used for residential solar installations is quite standard and the costs are basically set globally. For residential solar modules, which are typically of a higher efficiency than solar modules used in utility-scale solar farms, the figure would be a bit higher.
The story hasn’t changed much since then, even though prices on both ends have come down. However, in this case, your payments are likely to be less than the amount of money you’re saving on your electricity bill. Well, through my research I have found that the average cost of the off grid residential solar system in USA is around $3.75 per watt and it is without any rebate and tax credit offered by the government. At the same time, as an environmentalist, I would not mind producing more energy than I consume; the excess in grid-connected system will still be used by someone. Industrial customers use more and can take their electricity at higher voltages so it does not need to be stepped down. Utilities on the other hand typically install systems in the 100 mega-watt or greater range. Polysilicon suppliers made a lot of money and added tons of capacity so that there was a huge polysilicon capacity oversupply by 2010. Each generator consists of a converted GE Boeing 747 jet engine powered with natural gas which can be turned on with a click of a mouse and will generate 45 MW of power. These are generally combined-cycle plants (natural gas with a steam turbine) that are expensive but easy to turn on and off.
They are the backbone of the electrical industry and will remain so for the foreseeable future. It is the total life cycle cost of electricity for a given technology divided by the total life cycle electricity produced, expressed as cents per kilo-watt hour. Therefore, as far as new electrical facilities are concerned, natural gas without CSS, wind, and solar will be the main new contributors.
Transmission lines also require three to four years to build, versus solar or wind plants which can be easily built in two years.
Ken Zweibel of George Washington University says that is not the correct way to evaluate long life assets like PV systems, nuclear plants, or other large long lasting utilities. The chart at the left uses a weighted average (weighted by annual output performance) for the cost for the current year plus all previous years for each data point.
The Total Life Cycle Cost is the present value of all the components of cost over the useful life of the installation minus the depreciation tax benefit and residual value. The first-year energy production of the system is expressed in kilowatt hours generated per kilowatt of peak capacity. This rapid decrease in solar panel costs have helped make the technology more affordable for millions of homeowners across the country. Although these programs vary from state to state, they make it highly unlikely that you’ll ever have to pay full price for your solar PV installation.
Also, in some cases, a 3rd party solar company that sells you solar through a lease or PPA can take advantage of tax credits and incentives that you can’t take advantage of, and can thus offer you a better deal than you can get on your own.
Furthermore, as noted above, the 3rd party solar company may be able to benefit from solar incentives for which you don’t qualify, and then pass those on to you.
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…. Just note, however, that these averages are based on the cost of solar panels in 2011 (as I think you’ve gathered by now, the cost has dropped considerably since then). Zach is recognized globally as a solar energy, electric car, energy storage, and wind energy expert. That cost has fallen tremendously within the past few years — they’re now about half the price they were in 2008, and more than 100 times lower than they were back in 1977. So, really, you’re not paying any more than you’re already paying for electricity … you’re saving money! You made a right point that state like Arizona has lower payback period than the other states in America because of its excellent policy for the solar roof top.
Just because I don’t get paid for excess does not mean it would not be good in grand scheme of things. Peakers are rather small plants, ranging from 50 MW to 500 MW in size, normally about 100 MW.
PV solar is also cheaper than coal with CCS and it is unlikely that any new coal plants will be built in the US. Wind is somewhat limited as an average of 20 miles per hour (mph) is needed to be economically feasible. Once the initial cost of the system is paid for (assumed to be 20 years) the cost of running a PV system is almost zero, whereas for coal and other fossil fuels there is the cost of fuel each and every year. Most analysts believe First Solar, the leader in cadmium telluride, will continue to drive costs down. We assume no other maintenance costs as the panels are usually warranted for 25 years with a degradation clause.
For an accurate estimate, please contact a local solar installation contractor and your tax accountant.
The Total Lifetime Energy Production is all the useful energy produced by the installation over its total life. Solar at this time is completely lacking any commercial viability for most people and businesses. Telsa Power Wall + numerous other brands – there is HUGE competition here already in this area, and prices will be heading down very soon).
The devil is in the details, but for a lot of us it makes perfect economic sense even if you don’t care about cutting FF emissions. There continues to be a major overhang of polysilicon supply which is expected to continue for a few more years.
In addition, costs for fossil fuels may creep up due to raw material costs, shipping costs, and possibly carbon dioxide taxes. The chart illustrates that the two technologies are on distinctly different curves, not dependent on time but on volume. They are normally single-cycle natural gas generators, meaning no boiling water; the burning natural gas directly fuels the turbine.
So a PV system after 50 years will still produce electricity at 75% of its original performance.
Although crystalline silicone is inherently more expensive, its production volume is much, much larger than cadmium telluride. 50 years is perhaps a better time frame over which to evaluate the cost of this type of asset. They are very inefficient and expensive to run, but are great sources of electricity when utilities are on the verge of rolling blackouts. They are expected to slow down a bit, but will continue to decline from the levels used in the LCOE calculations above. Just looking at the curves, one would expect crystalline silicone to equal cadmium telluride in the near future.
