Go Solar Power For Homes

After the year we’ve had, it’s no surprise that the Top Ten innovations in solar power for homes mostly relates to making more energy for less money. However, amongst this selection, there are also some very funky ideas.

So, as we bring this incredible year to an end, Go Solar Power For Homes Dot Com brings to you our very own 2008 Innovations In Solar Power For Homes Award.

10/ ‘Hairy’ Thin Film Solar Panels From Nanowires

It was impossible for this development not to make it into the top ten, if only because it is so completely leftfield. Researchers at the uber-cool McMaster University have succeeded in actually ‘growing’ light-absorbing nanowires made of high-performance photovoltaic materials on carbon-nanotube fabric.

What that means in English is that we are now seriously looking at hairy solar panels!

In short, if we can make flexible, affordable solar cells that, within five years, could convert 20 percent of light, then we really have something here. Over time, the researchers suggest that they might expect to achieve 40 percent efficiency. We like the sound of that!

9/ Sunrgi - Making Solar Power Truly Competitive

Sunrgi claim that their system will soon be able to “produce electricity at a wholesale cost of 5 cents per kWh (kilowatt hour).”

How? By concentrating the Sun’s light into extremely efficient solar photovoltaic cells. This is very technical. You really do want to visit the treehugger.com page where they explain how Sunrgi’s Extreme Concentrated Photovoltaics work. It’s so great!

Their patent-pending technology involves everything from dual-axis sun tracking to cooling of the solar cells. Meanwhile, further good news is that the whole system is all set and optimized for mass-production. Bring it on!

8/ 25 Percent Cheaper Solar Panels Anyone?

Meanwhile, researchers at Day4 Energy are hard at work innovating their way to the top. They, more than most, are only too aware that performance in the marketplace is essential for business success.

They are not so concerned with beating solar PV efficiency records in the lab. They are looking more exactly at cutting the cost of solar panels by 25 percent.

How do they do that? By making solar cells that are roughly 18 percent more efficient than their competitors.

They have further good news in that they expect these super-efficient solar panels to be on the market within 18 months.

7/ Towards The Fateful $1/Watt

The race is well and truly on! Apparently there are more than 80 companies presently competing to be the first, the most efficient and the best at manufacturing solar panels with an output that costs less than $1 per Watt. This is the figure considered by most to be the price point at which solar panels, and solar power in general, becomes competitive with coal-burning electricity on the grid.

1366 Technologies are busy creating a multi-crystalline silicon solar panel that is 27 percent more efficient than conventional multi-crystalline silicon solar cells. Its total efficiency is running at 19.5 percent – roughly equal to the more expensive single-crystal silicon model solar cells. Though they have their challenges, not least the number of their competitors, but still, I wouldn’t bet against them.

6/ What Solar Panels Can Learn From Moths

The trouble with silicon is that it is reflective. So light that could be turned into electricity is lost because it bounces away. For some time now, a not altogether successful solution was to apply anti-reflective coatings. Then, some researchers looked at the make up of a moth, and everything changed.

Did you know that moths have extremely non-reflective eyes? This was probably a defense mechanism they evolved against nocturnal predators. Whatever … All you need to know is that because a lot of clever people have gone down this road, suddenly we have panels that lose just 2 percent of the light that hits them – a vast improvement over the 35 to 40 percent reflection rate or previous times?

5/ Solaria: 90 Percent of the Power from Half The Silicon

In these troubled times, you would want to be the manufacturers of a solar cell that produces 90 percent of a conventional solar panel’s power, while using only half the amount of silicon.

Solaria are justifiably happy to bring to the world a solar cell that slices the silicon into thin strips and spaces them apart so the silicon itself only covers half the panel’s area. From there, a clear molded plastic cover collects all the light from the panel and draws it to the strips of silicon. The whole process is complex but makes perfect sense when you read about Solaria’s innovation.

4/ Japan Races Towards Solar Power Station in Space by 2030

The new race for space has begun in earnest. Only this time it is not about getting people to the moon or Mars. This is about getting solar panels into space. You see, in space there is no shadow from earth, so there we have solar energy 24:7, and it doesn’t even stop for Christmas!

Many people are asserting that whoever gets up there first will be the inheritors of the earth. Just think of all that clean sustainable energy!  It’s hard to disagree. So the U.S.A. and others may want to take note that the Japanese seem to be currently leading this particular space race.

We are talking about a seriously massive project here though – think solar panels that are a kilometers long, weighing more than 10,000 tones. All that with a laser section that might need to be as much as10 kilometers long, with a receiving unit on Earth up to two kilometers long.

(CUE THE DRUM ROLL …)

3/ Turning Infrared Light Into Electricity

Imagine being able to not only use the visible spectrum of the sun’s light, but also to be able to gain energy from the infrared spectrum - solar panels making use of the infrared spectrum of light

Here’s how it works …

Scientists are developing a process where, by adding vanadium and titanium into the basic structure of a solar panel, you can get power from infrared as well as visible light from the sun.
Currently solar cells strike out at around 40 percent absorption limit. By making additional energy from infrared, we should be seeing up to 63 percent.

So, the 2008 Innovations In Solar Power For Homes Award Runner-Up Is …

2/Nanosolar: ‘Printing’ Solar Panels For Big Savings

Based in Palo Alto, California, Nanosolar’s creative team has come up with an innovative technique to make solar film. They simply print CIGS (copper-indium-gallium-selenium) onto a thin polymer sheet in a process very similar to an old-school printing press.

The savings on silicon are significant such that a Nanosolar solar cell will cost about one-fifth to one-tenth the cost of a standard silicon solar panel.

With investment from France’s EDF and with further interest from the owners of Google, Nanosolar are all set to go into mass production. If you have a few minutes, you can watch a YouTube video all about them. This is really happening, right here right now!

And so, the Winner of The 2008 Solar Power For Homes Breakthrough Of The Year Award is …

1/ Thin Film Solar Power For Homes

Thin film is all the rage. This technology requires less of our planet’s diminishing supply of silicon. It also adds new levels of flexibility and thinness so designers and architects love it.

However, it is essential that thin film is economical viable. So the US National Renewable Energy Laboratory (NREL) came up with a breakthrough that ensures that thin film solar panels are on the verge of being truly competitive with more established silicon-based panels.

A thin film solar cell has just been rated at 19.9 percent efficiency, in other words, 19.9 percent the sun’s light is converted to electricity by the panel.

This is a new world record and an important milestone. The goal for thin film technology is to match silicon in performance.

Made from copper indium gallium diselenide or CIGS for short, and it looks like you will be hearing a lot more about thin film solar in the near future.

Now, that is a breakthrough worth sending to the top of the class!

As the creator of a blog about solar power for homes, it is incumbent upon me to present the argument for alternative energy. It is not such a big leap from there into the world of politics. As my valued readers, I hope I don’t offend you by taking this blog off in that direction occasionally, as I did yesterday in covering the outcome of the UN Climate Change Conference. Well, I’ve done it again today in focussing on Al Gore. This really is not a left/right, republican/democrat issue. This is something we ALL could get involved in.

For me,  (aside from everyone who ever played for my favourite football team, ) there are very few genuine heroes in the world. Were he still alive, Mahatma Gandhi would be one. Nelson Mandela would be another. For the stand that he takes and the risks that he faces in taking that stand, in my view, Al Gore is fast becoming another true and genuine hero.

Some of you may have seen the following video from TED.com before. Nevertheless, while we are on the subject of Al Gore, I thought it a good idea to hark back to the days prior to the release of his award winning documentary An Inconvenient Truth.

Here is a short speech in which, with the same humor and humanity he exuded in An Inconvenient Truth, Al Gore spells out 15 ways that you can address climate change immediately. He discusses everything from buying a hybrid to inventing a new, hotter “brand name” for global warming.

Click on the text link to watch the video that outlines the 15 ways to avert a climate crisis according to Al Gore.

… and below are the 15 ways to avert a climate crisis spelled out for you if your technology does not allow you to see the movie, or if you are in some parts of the world like China where such movies may not be able to be seen.

15 ways to avert a climate crisis

1. Reduce emissions from your home energy use (better design insulation, green electricity)

2. Reduce emissions from your home and other transportation (buy a hybrid, use light rail, carpools, biking)

3. Buy the most energy-efficient appliances and other products. Be a green consumer

4. Live a ‘carbon neutral’ life. It’s easier than you think. Reduce then offset the rest

5. To find out how, go to http://www.carboncrisis.net. Use the carbon calculator there.

6. Make your business carbon neutral. (It’s not as hard as you might think.)

7. Whether you work in the design, technology or entertainment industries, integrate climate solutions into all your innovations.

8. Invest sustainably in companies and funds that are part of the solution. (Avoid making sort-term decisions with your money.)

9. Become a catalyst of change in your community. Teach others about the climate crisis.

10. Raise awareness by promoting An Inconvenient Truth in your community

11. Send someone to Nashville who can learn how to give Al Gore’s slide show in your community

12. Become politically active – Speak Up! Contact your elected officials. Make Democracy work!

13. Urge the U.S. to join the rest of the world community in capping and trading carbon emissions.

14. Rebranding global warming, use the term, “Climate Crisis”, though the name could easily be “Planetary Emergency”.

15.  Join together to avert the climate crisis. We are one.

These 15 points are as valid today as they were back in 2006 when the speech was made. What other points would you add to the list now? I encourage you to give us your comment below.

Well, you might argue that the solar power car doesn’t have anything to do with solar power for homes, but I disagree. You can park your solar power car in the garage, cant you? (Have the garage doors open and shut with solar power for homes!)

Besides, any good development to do with solar power anywhere has a knock on beneficial effect on solar power for homes in my opinion. Everything is connected!

So, how would you like to buy a brand new solar power car for $5,500, leave it outside in the sun for a day and a half and then do a 150km road trip without ever stopping at a gas station? No petrol costs. No environmental  issues. Just the journey and the destination!

Well here is some good news. The Chinese company, Zhejiang 001 Group has just produced China’s first ever completely solar- powered automobile.

The compact efficient solar power car uses solar panels on its roof, turning sunshine into the electrical solar energy that moves the solar power car. They say that the solar panels will absorb 95 percent of the solar energy that lands on them, transforming roughly 15 percent of that into electrical current to activate the solar power car.

The solar power car is a response by the Chinese government to head off an oncoming energy crisis. So far the group has only made a few of these cars. They are set to sell for 38,000 yen, roughly US$5,500.

According to their scientists, if you give the car 30 hours of sunlight to feed off, it will give you back 150km of clean good driving, leveling out at 5km per hour of sunlight.

To have a car that will transport me to and from my work every day, while making no carbon emissions, I think US$5,560 would be very reasonable.

Think about it. Given that you would have no fuel costs, how long would it take for you to get your money back? Well, let’s work it out …

According to the AAA’s media site for retail gas prices, the average cost for a gallon of regular today (11/30/2008) is $1.825 and for a gallon of diesel the price is $2.756. (Believe it or not, in mid July 2007 those figures were $4.114 and $4.845 respectively!)

According to  fueleconomy.gov the most efficient car right now is the Toyota Prius at roughly 45 miles per gallon.

So at the very lowest costs, every 45 miles of driving would cost you $1.83. So, I’m no mathematics genius but correct me if I am wrong. You would need to drive your solar power car for just 3,005 miles to break even. After that, all your ‘fuel costs’ would be free.

Don’t know about you, but my car is already at 75,000miles, so I’m thinking that this might be a winner. (Maybe pimping up the look a bit might help though!)

Talk about making diy solar power for homes? Here is an amazing YouTube video which shows you how you can make yourself a solar shingle roof that is as cheap and easy as anything. In fact, making and fitting a solar shingle roof is so inexpensive it would cost more to have a normal traditional tile roof installed!

So watch this video as our solar shingle roof guy shows you how very quickly and easily you can make your own solar shingle roof and have it give you free energy, meanwhile solving the problem of cladding your roof. This really is a genuine way for you to make diy solar power for homes.

The guy shows you how to build the solar shingle roof from basic materials. This solar shingle roof is built in front of your very eyes so there is no mistaking how you too can create diy solar power for homes for yourself and your family.

In order to build the solar shingle roof he starts with a mock up for the roof. Starting with plywood covered with Polystick TU Plus, you can watch as your diy solar power for homes takes shape!

He incorporates metal shingle which is easy to find at most hardware stores. He then puts Unisolar solar film on it to make this type of roof a solar shingle roof that will produce electricity for your house in a ‘diy solar power for homes’ type of way!

By using dummy shingles with exactly the same looking frontage, making a solar shingle roof in this way means you don’t have the problem of two colors to your roof. This way the whole roof looks the same color as the whole roof is either solar shingle roof panels or dummy solar shingle roof panels.

At the top of the solar shingle roof panels run the electrical wires that are easily connected together as you fix the solar shingle roof panels to the plywood.

To make the diy solar power for homes installation even easier, the solar shingle roof panels come with a little slot that allows each of the the solar shingle roof panels to slip into the next easily. In this way, everything is made watertight.

Safe underneath a raised gable trim at the end of the solar shingle roof, the main cable takes the electric power away and feeds it into your home. Fitting a complete solar shingle roof can be done for less than the cost of a traditional tile roof.

As the man says, “If you’ve got to put a roof on your house anyway, why not make it pay your electric bill?”

Good work, solar shingle roof guy!

If you have not already installed solar power for homes, are you worrying about the price of your gas and electricity? It would be no surprise if you are.

After all, not everyone has solar power for homes fitted yet and traditional fossil fuel based energy prices are sure to be going up and up as we move into a more and more uncertain future. Now, more than ever, it’s time to install solar power for homes.

With or without solar power for homes, right now you may still be struggling financially and ‘feeling the pinch’. However, a different kind of ‘pinch’ lies ahead.

Scientists predict we will run out of oil in about 50 years. This fact is looming over us and its shadow makes our future appear bleaker and bleaker. As the oil runs out, so the prices will rise. The case for solar power for homes will improve with each passing day.

Sadly, the price of oil does not only affect car drivers. It has a direct effect on many things, not least the price of food. As the price of transportation soars, so will the price of the products being transported.

No doubt your home is already run on a strict budget. Imagine how it would be if, suddenly, everything doubled in price? Introducing a range of sensible measures, including installing solar power for homes, would seriously reduce the impact of this price hike, maybe even eliminate it from your household completely.

I hope you are beginning to see why it is essential that you start to consider installing solar power for homes. Start to plan, and start today. We need to take action to protect ourselves, to insulate our families from the impact of this future turmoil. Consider the possibility of installing solar power for homes soon.

We need to be a great deal more efficient in the way we consume and use our energy supplies. If we don’t, we can be sure that the traditional fossil fuel suppliers will continue to punish us with their massive price hikes.

We just saw the gas companies in the UK put their bills up by 30%. When wholesale prices dropped, did we see any significant drop in our gas bills? I rest my case!

With solar power for homes, you need not be tied to the grid any longer. Any surplus energy could be sold back to the grid, providing solar power for homes elsewhere.

Aside from installing solar power for homes, as individuals we can take steps to improve our energy efficiency. For starters, we need to go solar power for homes as soon as possible. For another, we need to look in all directions for alternative energy saving ideas.

The good news is that this is nowhere near as complicated or restricting as you might think. As you take action, so others will follow. As others follow, so we begin to make an impact. Right now, as you sit there reading this, you want to know that it is up to YOU.

“Be the change you want to see in the world,” said Gandhi. Spread the word about solar power for homes. Have your family talk to all their friends about solar power for homes. The more we talk about solar power for homes, the more rapid will be its introduction.

As more and more people take on solar power for homes and other energy savings, so the demand for traditional energy supplies will fall. As demand declines, so the prices will come back down. This is basic economic common sense based on the age old rules of supply and demand

So it is time to incorporate solar power for homes into our plans for living more efficiently. With good planning now, your lifestyle won’t have to be impacted hardly at all.

There are many ways to start this process. Why not begin by taking an overview of all your electrical appliances all around your home? Are they all working efficiently? Do you really need all of them? Can you replace old style bulbs with energy efficient ones? Do they have to be switched on as often as they are?

Be sure that everything that is not needed is properly switched off. Never leave anything on ’standby’. Enroll the whole family in this new game, the game of saving some money while saving the planet!

We are unlikely to get much support from the major energy companies. Their interest is in having you consume and continue to consume. You must take a stand against their frivolous ways. Did I mention installing solar power for homes?

Turn off your computer monitor, even if it is only for a few minutes. It’s a myth that it’s more expensive to switch an appliance off and on rather than have it switched off for a period of time. Rubbish! Switch it off, and the same goes for light switches … and especially for air conditioning, one of the largest energy consumers of all.

The combination of installing solar power for homes and using all appliances more efficiently will save you lots of money. You could cut your energy bill by as much as 33% or more.

I’ve just touched the surface in this short article. There are so many other ways that you could reduce your electricity bills, not least of course would be to install solar power for homes.

You can find out if solar power for homes is suitable for you while discovering lots more practical money saving tips by clicking this solar power for homes link.
