Well, I guess you might want to know what is the real cost of solar panels for home.

If you browse over the Internet, it may take quite some time or maybe you will find nothing to find what is the real cost of solar panel.  And most of the time, writers or bloggers will make an estimated value like the average cost of solar panels installation, which would be around 40,000 to 60,000 USD per installation.

Well, without knowing if it’s true or not, I believe it will only make the name of this green energy look horrible in terms of its price.

But…

Gladly, today I just collected 4 case studies of the exact cost to install a solar panel.

These case studies came from a real person, like us, that loves green energy.  Not just to save the world. I bet that is not the only reason, but more to save money up front.

Before we go further, I just want to acknowledge some of the information that we are about to find out:

The installation was done by a trusted solar panel installer. So, you may know the company from which they were hired.

Most of the installers completed the work in about 2 days.

Some of the material presented by them was a blog post writing, which will take quite some time for you to read. Even better, there is also a video presentation. Which I will start with first, right after this.  So you can better understand how solar is installed and how it works.

For the blog post presented by owner, I tried to make a summary of it.  Some of important points that I will cover on their brief project, of course, in terms of the cost, I will breakdown those costs to what purpose, and so on, as this is what we want to know for sure.

The idea of this post is to show how wrong it is to say that the average cost of solar panels for a home may reach $50,000, without saying how we can decrease that cost.

Without further ado, let’s get started!

From John P on GeekBeat.TVJOhn P

Our first case study, talks about how John P installed a solar system on his house.  John P also has made a 20 minutes video to show how his system has been done.

But before we watch,

Let me summarize a few of the important points that John P mentioned in  his video below:

Actually, it reminds me that solar panel systems can last a long time.  And yes, most of us will proudly “announce” telling anyone it’s guaranteed to last as long as 25 years.

But, does this include all the equipment? Of course not, because we still need to change the inverter probably at the halfway point of the system’s lifespan.  But this does not mean big problem at all because within 10 years from now. New equipment will perform better as improvements are made and developed, meaning that it will help improve our system over time also.

The 2nd thing for me that I think is why in the hell did I not think about it before is, if our solar arrays can be used for 25 years, well that’s nice, but how about what it’s standing on?  In most cases, it is on our roof.

Can the roof actually make this work?

Pssst

Don’t believe anything he says in the video. I believe if we can install this system ourselves or with better program plan instead of just purchasing the system like what John P did, we will get a better investment in the future.  I don’t think John P wanted to go green. Instead, he just wanted to show how this system works, which is good, in order to let us know the pros and cons of asking some company to install it for us.

So, as seen above, this system costs 30,000 USD for a 10kW system and 60 percent of that cost is just for hardware.

After a 30% tax rebate and some payments completed, the net cost is 11,500 USD.

And John P stated it takes 10 years to get payback from this system.

http://geekbeat.tv/the-complete-guide-to-installing-a-pv-photovoltaic-solar-panel-system/

This system is installed by Axiom Solar, according to John P on his blog. But I’m not sure if he spells that correctly because when I searched Axiom on Google, it provided me with a solar parts dealer.

But, I did found something close to this name, which is Axium Solar, and yes, their website looks like they are a solar installer.

I’m still not sure about it and I don’t really care to ask him. So, I’ll just let it be… :)

Let’s move on to our next case study.

Bob KovacsBob

http://www.bobkovacs.com/

Bob Kovacs makes our second case study.

After watching his videos and website, I can say Bob Kovacs and his wife, are a true family that loves green energy. And his video presentation below proves a lot.

Bob did two videos talking about his solar system. The 1st below was during the installation that has been done. Not very interesting to watch I think, its look like Bob just whispering himself that suddenly on tape for us to see. :)

In addition, for the second video, Bob presented the cost included in his project.

Let’s watch the installation video below. You may want to speed it up a little bit because it is not as fancy as John P’s video.  However, this video does help us to understand how the installation has been made.  Plus, it just takes 9 minutes of our time. Two days took to complete, by the way.

As mentioned earlier, the next video is going to be the presentation of the costs of this system.

So, after around 20 minutes, what we understand and get are:

The net cost is still around the cost of John P.’s system. About 11,500 USD for a 10kW system, right?

But for Bob, the 18.2 kW system got up to 18,765 USD.  So, in terms of ratios, it’s kinda same.

After watching this video, I wondered about the Virginia rebate grants, and it looks like they still have them available.

Sorry, I’m not going to give provide more details about how to apply and all that stuff, but, you can refer to this page for more info about rebates. http://www.cleanenergyauthority.com/solar-rebates-and-incentives/virginia/

Kevin C. Tofelkevin C tofel

http://search.gigaom.com/author/kevintofel/

Our third case study was made by Kevin Tofel.

I believe you might have read this post before because it went viral and was spread all over the place.

For those who did not, you can read it here:

https://gigaom.com/2012/11/11/one-year-with-solar-energy-at-home-mostly-sunny/

Nevertheless, here is my quick summary:

At first, Kevin wanted to start installing this system because he wanted to escape from large tax bills.  So he decides to invest the funds into a tax incentive as a backup.

The upfront total cost is $51,865 for a 9.43kW system. Yeah, I know, it’s much higher compared with the other two guys before mentioned.

With 30 federal tax credits, it only reduces the cost around $15,560.  And just as Virginia had a rebate offer, in Pennsylvania, Kevin received a rebate in the amount of $7,100.

So, the final net cost is $29,205.

The price is quite a big chunk of money, probably because Kevin did not use a normal Inverter that most installers use, or string, or central inverter, because Kevin use the micro-inverter.

You can read more here, http://energyinformative.org/are-solar-micro-inverters-better-than-central-inverters/

By using the micro inverter, your system will most likely become more productive.  Plus, because of the micro inverter, it will not be exposed to high power and heat loads as a central inverter.  And they also tend to last significantly longer. Micro-inverters typically come with a warranty of 20-25 years; 10-15 years longer than central inverters. Courtesy of energyinformative.org

Our Last Contender is Allison Huke from ocgreenmama.com

Allison is quite a super active housewife.Allison

And yes, she has decided to go green in everything that she can.

Some of the green posts on her blog include:

DIY granite cleaner

The use of plastic bags – read this. Allison shows in a detailed article some facts about plastic bags.

As Allison wrote in this blog:

I think we should use plastics more wisely and more sparingly. You can reduce your use of disposable plastic. You can also choose safer plastics, particularly for those items that are likely to come into contact with your mouth – the most common way the chemicals in plastic enter our bodies.

And of course, the last one that attracted us a lot, is her solar system.

Allison project

This case is unique from the rest of the case studies mentioned above.

Well, most of us will somehow think (including me) that we are a bit off from our objective. Going green, but without even turning on or using the power, already cost us $20,000 and up to $30,000.

But not Allison, she chosed the pre-paid program out of another 2-way plan. She completely purchased the system and PPA solar, click here to find out more. So the payback time will come around the next month of using the system.

As a pre-paid plan, Allison had to pay $22,000 upfront, and her calculations assumed that she would save $90,000 in energy costs, over a 20 year period.

To understand Allison’s progress, she wrote it up in a 7 part blog post series.

I did summarize a bit its content, but you still need to read it on your own in order to have a better understanding about how this system works.

Part One, Making the Decision

After she moved, she received an electric bill of over $400 in one single month.  She decided that she needed to do something about it.  She tried to lower the bill by applying a basic conservation approach, like switching to LEDs, and control bad habits like turning off appliances that are not in use. But still, she needed around $300 for expenses per month. This is why, she ended up going solar.

Part Two, Financing

Most of us are so pessimistic about solar, due to the high up-front costs. But, of course, that’s because of the purchasing strategy that they are using. Or perhaps that’s the only option they had. But as mentioned, Allison chose a pre-paid plan. Thus, in this post, she goes into even more detail about the process.

Part Three, Auditing & Evaluation

After she decided to choose Solar City in the first post, Part One, in this third part of her journey, Solar City representatives started getting down to business. They started evaluating the effectiveness of solar for her home.

Part Four, Rebates and Approvals

As what you might know, most of the installers will process all the hard work, like processing the rebates and approval they need.  From what I read, it looks like Allison needed to get the signature from her neighbors. That’s it.

Part Five, Installation, Inspection and Flipping the Switch

With all that being said, Solar City started the installation that took two days to complete. But, it couldn’t be turned on until it received final approval from SCE.

Part Six, A Month to Month Comparison

I think it is around August, 2013.  The electric bill for Allison is down to only $14.19.  Read here to learn how it happens.

Part Seven – First-Year Savings

After one complete year of using a solar panel, I know you are so eager to know how much money she managed to save.

Well, after she made some calculations, if she had not gone solar she would have had to pay $6823.15 in 2013.  However, after making the right decision, she (and her husband) only paid $2203.37.

That’s it for now.  I hope this post will inspire many of us that still don’t believe that solar will help in saving money and building a better future for earth. Bye

You often hear about global warming in discussions, books, articles, and even in conversations at a party. And whether it interests you or not, this is not something that can be ignored anymore. It is a scientific fact, and all the signs are screaming at us to prove that. Devastating hurricanes, tsunamis, earthquakes, massive flooding, terrible wildfire – just to name a few. Perhaps we should dig deeper and see what the fuss is all about?

What is Global Warming?

Here is a dictionary definition of global warming. “An increase in the earth’s average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect (more on this later).” Let’s see what does this all mean. But first, take a look at the picture (source: Skeptical Science) below that shows signs of global warming.

the causes of global warming picture

Source: Skeptical Science

Notice things like melting glaciers, rising humidity, sea level rising, arrival of early springs and more. They all tell us one thing – our planet is getting hotter. Before we delve into the causes of Global Warming, let’s briefly talk about some of the terminologies such as greenhouse effect, greenhouse gases, etc.

Causes of Greenhouse Effect

The planet earth receives sunlight from the sun. The earth then absorbs some of the energy and becomes hotter. It’s similar to the way our homes radiate heat, long after the sunset, especially during hot summer days. The reason is that the house has absorbed a lot of energy from the sun. After the sunset, the earth cools down and gives off something called infrared radiation. However, the gases in the atmosphere, known as the greenhouse gases, block some of the heat radiation from being released back into outer space. If this natural process didn’t happen, the earth would be a very cold place. This whole process between the sun, the atmosphere, and the earth is known as the Greenhouse Effect. The balance of the atmospheric gases is crucial in keeping the earth’s temperature constant. However, some things are causing an imbalance in those gases, resulting in a continued rise in the planet’s temperature, slowly but surely.

What causes Global Warming?

Believe it or not, first and foremost, it is us, the humans who are the major contributors to Global Warming. Humans emit several greenhouse gases from our cars, factories, and electricity production, and the gas that’s responsible for heating up the planet is carbon dioxide, also known as CO2. Other greenhouse gases include the methane gas from landfills and agriculture, nitrous oxide from fertilizers, gases used in refrigeration and other industrial processes. Fluorinated gases such as Hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride are synthetic, powerful greenhouse gases. These are emitted from different industrial processes. Some gases are more effective than others, and some could remain in the atmosphere up to a few thousand years. Forced deforestation is another major factor as the trees would’ve stored some of the CO2. With declining forests, more carbon dioxide is being released into the atmosphere.

U.S. Greenhouse Gas Emissions in 2012

list of effects of global warming
Traffic

The atmosphere is becoming like a thick blanket due to carbon dioxide and other air pollution. And this blanket is trapping the heat from the sun, causing the temperature to rise. How do motor vehicles contribute to the overall air pollution? In the US, automobiles are the second largest source of carbon dioxide pollution after the coal-burning power plants. Motor vehicles generate almost 1.5 billion tons of CO2 annually. Sixty percent of these emissions come from cars and trucks, and the remaining are from heavy-duty vehicles and airplanes.

Cars and trucks contribute to carbon emissions in three different ways:
• The amount of fuel they use.
• The type of fuel they use – meaning the amount of carbon released when a particular type of fuel is used.
• The number of miles traveled by the vehicle – more you drive your car, more CO2 is being released into the atmosphere from your car.

Deforestation

Should you hug a tree? Although the idea was more spiritual than scientific, today scientists are discovering the benefits of hugging a tree. hug a tree imageNo, I am not here to talk about that, but rather the relationship between deforestation and global warming. And after you’ve seen the benefits of trees in our lives, you may even want to hug one.
You’ve heard of rainforests. They are responsible for forming a cooling band around the equator. Now that more and more rainforests are being destroyed, the earth has begun to experience climatic changes. This is because carbon emission from deforestation is much greater than the damages caused by automobiles and planes. Deforestation is considered to be a hidden but a major cause of global warming.
Recent studies reveal that Indonesia has become the third-largest emitter of greenhouse gases in the world. Brazil is right behind it. What is amazing is that none of these countries contains heavy industry on a comparable scale with the major industrial countries in the world. The five countries with the largest forest areas are the Russian Federation, Brazil, Canada, the United States and China. Together they account for more than half of the planet’s forest area and the Russian Federation alone accounts for 20% of the world total. Except for the United States and China, Indonesia and Brazil have exceeded all other countries in this respect.

So, what’s really happening there? Both rich in tropical rain forests, but losing their forests at an alarmingly high rate. The forests are being cut and burned, and you can even see the smoke stacks from space. The same could be seen in other parts of the world as well, for example, the Congo basin in Africa. More than 50 percent of the life on earth can be found in tropical forests, which occupy less than 7 percent of the planet’s surface.

The rainforests generate the bulk of rainfall worldwide. They are like the thermostat for our planet. Many people may not be aware that the forests are also home to 1.6 billion of the poorest population of the world. These people rely on the forests for their subsistence.
Coming back to global warming. With less rain, less water, and more carbon dioxide being released into the atmosphere, our planet is warming up a bit more each day and although it may not be noticeable, massive destruction caused by imbalance in nature are all around us.

estimate solar energyInstalling a solar power system on your home or business is an excellent way to lower your energy costs while benefiting the environment. Many different types of solar panel kits and systems are available ranging from rooftop models to stand alone systems and and many can be easily installed by an industrious home owner. You won’t have to obtain an engineering degree or anything like that to get the job done and you don’t have to hire a high-priced installer. In fact, it’s fairly straight-forward. Many times solar panels come in kits that include very specific instructions on how to install them properly so it is just a matter of following directions.

The amount it will cost you to install solar panels on your own home is dependent upon a number of factors including the number of panels, condition of the roof as well as any tools and supplies you may need to purchase. According to the Solar Energy Industries Association; “Common residential system prices ranged from less than $3.00/W to almost $8.00/W”. This includes labor and the price of the system itself. It’s clear that if you eliminate the cost of labor, for a professional installation, the price will be lower, but, again, it varies depending on your individual circumstances.

 

How Solar Panels Work

Solar power can be a mystery in terms of just exactly how it all works. Most people understand that it all begins with the powerful sun that transmits energy through the atmosphere and onto the solar panel. But, what happens within the solar panel that produces electricity?

how solar energy work

Courtesy for maceenergy.co.uk

Solar panels are made up of smaller units that are referred to as “photovoltaic cells”, which means that they convert sunlight into electricity. Solar panels are made up of several of these cells that are all linked together. These photovoltaic cells are a kind of sandwich, if you will, that is made up of two pieces of semi-conducting material like silicon. One piece of the silicon has a positive charge, the other a negative charge. This creates an electric field between the two.

When sunlight, or more specifically photons from the sun, are filtered through the solar panel, they end up in the middle where the electric charge is. This causes the solar panel to release electrons. Conductive metal plates on the sides of the cell collect the electrons and send them traveling down wires. Sometimes the electricity is directly fed into the electrical outlets in our homes, just like any other source of electricity. Other times, the power is directed to batteries to be used at another time. Excess power, what we can’t use or store right away, makes its way back into the power grid and can be sold to the power company.

How Many Solar Panels Will You Need?

how-many-solar-panels-muppetThe number of solar panels that are needed depends completely upon your specific electricity needs. If you run a large number of electric appliances that are older and not energy efficient, you will need more than if you have high efficiency appliances. That said, the average home uses right around typical solar panel produces around 200 watts of power and the average household uses about 48 kWh of electricity per day.

What that means is that the average home will require a 5 kWh array, or roughly 25 solar panels to provide adequate power. That said, some households may only wish to provide a percentage of the total power from solar energy while others will wish to go for 100%. The level of production required will determine the number of panels that are necessary. To find out just exactly what you’ll need, use one of the online solar power cost calculators to figure this out. You’ll need some basic information such as past energy usage which you can find out by looking at your utility bills. Just fill in the requested numbers and you’ll get a good idea of how many panels you’ll need and an approximate costs associated with them as well as when you can expect to see a return on your investment.

Keep in mind that you do have to take the time to be sure that you understand the local and state regulations regarding their installation. Since every state, city and municipality has their own specific rules, it is impossible to list them all here. However, you can find out more information by doing an online search for the regulations in your own area. Once you’ve gotten that information, you’ll be ready to get started.

If you’re serious about saving money on your energy costs, not just in the short-term, but for the long-haul, solar power is the way to go. There are many excellent solar power companies that provide complete kits for the do-it-yourself inclined person that are quite reasonable and the prices are going down all the time. By taking the time to install the solar panels yourself, you’ll save money on the installation, and the system overall. Plus, you’ll have the added benefit of being able to brag about how you did the work yourself and how low your utility bills are now that you’ve gotten solar power connected to your home. As an added bonus, you could produce more electricity than you use and you might even get a check from the power company for selling the excess power back to them.

The usage of non renewable sources of energy is increasing day by day and the day when the world will run out of them is not far off. The pollution and destruction the non-renewable sources create may eventually challenge the very existence of the human race on the planet, hence it is important that we start concentrating more on green sources of energy.why are solar panels wired in series

Solar energy is one source of green energy. The solar energy can easily be tapped with the help of proper use of solar panels. Solar panels are used to generate electricity from the sun and are the most preferred sources of green energy. Solar panels are available in the market which can be bought in the required number as per requirement and installed.

The working of a solar panel and why are solar panels wired in series:

The output of a solar panel is always a DC voltage. Home appliances work on AC, hence the generated DC voltage has to be converted to AC voltage using inverter. But, the DC output of individual solar panel is low and the AC inverters need high DC input voltage to work. This can be solved by connecting various solar panels in series, where all the voltages generated by individual solar panels will be summed up. Hence this should explain why are solar panels wired in series. One more point should be taken into account that is the total output voltage of all the solar panels connected together in series should not be more than 600 V in DC.

The problems with series connection of solar panels:

This may seem to be the solution to get high input voltage to the inverters to convert the DC voltage generated by the solar panels to AC voltage, there is a problem that rises up as soon as you connect panels in series. That is, if all the solar panels generate equal amount of voltage then the system will be working just about awesome! But if one of the panel is under the shade of a tree or is delivering lesser amount of DC voltage as output then the efficiency of the system drops drastically, by say 20% to 30%.

The solutions to the problems generated by the series connection of solar panels:

The obvious solution to the above mentioned problem where the solar panel gets shaded due to a tree would be to cut down all the trees in the near by region around the solar panel. Similarly, the other alternative for tall skyscrapers or multi-storied building would be to have the solar panels installed on the roof tops where the panels are not obstructed by any trees or other objects.

But, practically speaking, partial shading cannot be completely avoided right? So, there is an electronic solution where the system equipped with bypass diodes or microinverters to reroute the current around the under performing solar panels, but rerouting again has a small glitch where it will result in the loss of potential energy from these cells and lowering the entire string’s voltage but only to a small extent, hence this method can be used where there is the problem of shades effecting the efficiency and productivity of the solar panels connected in series.

By fine tuning the series connection of solar panels one can easily make efficient use of sunlight and generate enough electricity to drive a home. The fine tuning is the most time taking process and varies according to the region and the atmospheric conditions.
