Homemade solar panels/wind turbines - Page 2

Hello Everyone!

(replying to everyone not to a specific person)

As you can probably see, I just joined this forum. I have read the entirety of this thread, though because of an extremely slow Internet connection, it has taken me over an hour to log on, bring up this screen and type this up.

First off, I would like to say that all of you (or at least the vast majority) seem genuine, not try-hards who know nothing (and those of you who do not know anything seem to be interested in learning). I am addressing the first section to they guy (or girl) who said that they would like to live completely off the grid with their home powered by wind and solar power.

It is a relatively easy thing to make a solar panel, and if you would like, I can give you (for free) instructions and suggestions that should make them a lot more durable and reliable. The difficult thing is converting the raw energy (DC, anywhere from 12 to 48 Volts) into 240V AC power (or 110V AC in America-correct me if I am incorrect). And it is even more difficult to completely convert a house completely over to renewable energy sources.

*(Assuming that you know a fair amount about electronics and have good soldering and carpentry skills, then it would be well worth the effort to buy solar cells off Ebay. Just go onto Ebay and type in solar cells. Years ago I purchased ten cells as a proof of concept idea, and I received thirteen instead. Only one was chipped, though I broke most of the rest due to poor handling and dexterity, as well as youthful over-enthusiasm.)

If you want to be good to the environment, then I suggest building a relatively large array of solar panels (800W at least, preferably more) plus all associated hardware. In the case of inverters, I would suggest using a grid-tie inverter; feed energy into the grid, use only as much as you need during the day, at night draw energy from the grid. This idea is most certainly not original; it is called Virtual Energy Storage-look it up, other websites can explain it better.

Basically you use the main power grid as a virtual battery (although the energy is not actually stored, it is distributed to other homes, businesses, factories etc). As for wind power, I have very little experience in that regard. It would certainly only be worth investing in if you experience high winds for at least 20+ hours a day. Certain seaside or mountainous locations may experience conditions such as this, however.

The actual storage of power on-site with batteries is extremely expensive and the manufacture and disposal of batteries is very bad for the environment, depending on the batteries you are using. Batteries are hideously expensive and unless you are salvaging and regenerating say, banks of old car batteries, it is not worth the effort. If you are truly determined to become a little more independent, save some money, help the environment and more importantly make your objectives achievable, then I would recommend banks of home-made solar panels (again assuming that you are at least competent with electricals and carpentry-if not then buy them, do not take the risk) with a grid-tie inverter using Virtual Energy Storage.

(Another little side-note: most but not all grid-tie inverters DO NOT offer power backup; if the mains fails, and you have three staggered batteries of solar panels, they will not give you any backup power whatsoever. You will have to pay a pretty penny in order to get one that does (as a starter, go to ww.jaycar.com, and looked up SuperCombi or CombiPlus, just to get an idea of the sort of prices you will be paying if you buy your equipment commercially (remember, that is just the inverter, not counting voltage regulators ($250-$500, mounting hardware, solar cells etc)).

Please reply to this and\or ask questions, even set me straight if I have made a mistake or posted flawed data. I have done tons of research over the last three years, read hundreds of articles, trawled dozens of forums, read dozens of books and run half-a-dozen mathematical and financial simulations. And remember, keep your objective achievable.

I built a wind turbine to provide some power on the remote property. It works great, when the wind blows. However, I wanted more power, and more dependable power like Solar Power Queensland. The wind seems to blow all the time on my property, except when I really need it too.

There is one, easy DIY project for everyone who want to cut the cost of home heating. Air inside living space can be heated using DIY solar panels made of pop cans. You can easily build one and save a lot of money and also enjoy while making it...

I agree with the previous comments. I think there is enough free information out there and I would suggest that you don't neccessarily need to pay for the advice and set up. From my experience I think installing a wind turbine is probably a more easier operation of the two and I've recently done just that myself with an outbuilding down the garden, which I use a workshop. It's entirely self sufficient in it's energy and electricity needs. Perhaps you could start with a project like that to begin with. Keep your eye open too for components. There are a few suppliers like this that are springing up and even eBay isn't all that bad with some of it's sellers. It is possible and it would save you money to do it on your own. But if I had the choice I'd like a professional to do it, namely because I know it's being done right and the system is as optimal and as effective as it can be for me!

QUESTION...  Why bother with solar panels when a single plasma energy battery can power your entire house and everything in it for over a decade without a recharging and with the same radiation level as a cell phone?  No, I am not drunk.

 I agree with the above. Building your own solar panels is a fun experiment, but not as smart for everyday as buying reliable power methods in a real market. If you are confident and interesting, go ahead and have a try.

Had a look at the video for windturbines above seemed do-able but personally i'm not to sure about the concept of making your own turbines as i've never been convinced due to actual amount of wind need to generate a good sustainable amount of energy.Think a previous comment said you'd need 28mph wind to achieve good results, I mean thats ok if you live on the outer hebredies so I'm still inconvinced.But would definietly love to hear back if you went for it and had a go a building your own system and how you found it. Found a good video at the following address and it comes in

a series: http://www.youtube.com/watch?v=ZCzkDpisFLs 

Will definitely check back and see if you went for it, but if you don't I would still look in to solar as their are so many incentives still to be had read a good article recently stating how now is a better time than any to get in to solar: http://www.solarkinguk.com/blog/generate-free-electricity

But i totally understand why you are considering doing it yourself as the cost can be huge depending on the size of your house and the system you'd need

Hi,

Been exploring ways to improve on saving energy, renewable energy, cost savings when the funds aren't there to have commercial solar installation.

Seems you can rent or lease solar setups, too.  There are a number of articles submitted by home owners who found ways to reduce costs for little or no money.  Also, you will remember the expression "necessity is the mother of invention" and there are a few individuals who have worked out the problems and procedures for starting to build to of your own solar units - roof mounted or on the ground.  I found this website that lists a number of ways to improve energy use and articles submmited to Mother Earth News by families.  Take a look at http://www.greenerdiyaffordablehomeprojects.com.

SOLAR PANELS ARE FRAGILE AND SIMPLE NOT ENERGY EFFICIENT. THEY MAY BE GOOD FOR STREET LIGHTS AND REMOTE COUNTRY-SIDE

APPLICATIONS BUT THE BULK OF OUR POWER IN THE FUTURE WILL COME FROM CLEAN GREEN NUCLEAR - THORIUM.  I SUGGEST  YOU  GOOGLE

"THORIUM PLASMA BATTERY TECHNOLOGY"

AMERICAN People we have got to stop sending Billions and Billions of dollars out of the country for fossil fuel. It never comes back. We are going to be on our knees soon. We have more fossil fuel in this country than we could ever use. They say we don't have enough of the refinery's here to refine it. My God can we all pitch in and build some . Is it a conspiracy to break our Country so we will bow down.......

Do Not spend thousands on solar power. This is dead simple to build your own, with the down and dirty low prices on the right parts. All I can say Is EASY EASY  These people are saying they can drop your current electric bill down to 15% of your current bill, or even off the grid for less than $100. Watch the 100% free video It is awesome. Just awesome ..I don't mean to spam, but I am just so impressed with this plan. Thanks Tony Brazier .. htp://dmoneypump.info
