Building Solar

I RECOMMEND THAT YOU HIT THE "CAPS LOCK" KEY.

Yes, capitol letters are SHOUTING! How rude!

sorry, new at this

sorry

Kenn,

I agree with bhankiii. Don't use all caps in your posts. It's difficult on the eyes.

I couldn't find a question in your post. I suppose you're asking for an opinion then.

That's a nice idea. There are a lot of converters in the market and you'll find one easily by googling for it. Globalspec also has a search engine that's better for this since the results of your search would be more filtered.

You could buy a small converter and add more as your system grows or you could buy a big one and just plug in your equipment depending on your capacity. In the long run, it's cheaper to buy big. I always say that but buying smaller is sometimes what you can afford. You'll be the best judge of that.

Thanks for the advice. This was my first attempted at useing this service.

I know of the small converters ,but can you put them in line like the p.v.panels?

I do not know in which area of world you live in? There is another way too to benifit from solar, You can heat up your house, cool your house, and fulfill hot water requirements too, by solar direct heat radiation, by installing vacuum tube solar water heaters of aproprate size.

Solar energy is still costy up till now, as compared with conventional energy sources, but this is free, long life, no operational cost and return back is 2 years.

When it comes to solar heating there is basically nothing you can do wrong.Just some things work better than others. Use a ratio of one sq.ft. of solar collecter for each ten sq.ft of house. I live in Wisconsin and that ratio worked very well for me. The design for solar hot air and hot water heaters are as varried as the do it yourselfers that have built them. Solar electrical is still the most expensive, by far.

HI ALL !

The new thin film solar collectors can go for 2 dollars a watt. now if they could increase the output of the collectors from 135 watts for a 20 foot section to 270 watts per 20 foot section. this increase is essential for the continued consideration of this product in all solar projects.

thanks

You made the right remark: these thin film is not good for wide usage. 7 to 8% efficacy is way to low.

Only in applications where you need the folding/thing forms it can be handy.

HI Gwen !

I AM glad you agree that thin film just is not efficient enough for general usage but some day they will improve the efficiency and they will be good candidates for solar projects.

THANKS

I was wondering whether it isn't possible to work with layer deposition on a PC or COC substrate.

You could make a car body form out of these polymers, they are tranclucent and widely used for optical components. On the back ot the part you can make a solar PV cell over the complete car surface, a loss in efficiency would be gained back in extra surface and the car battery is replenished while it awaits for your return after a hard day's work.

Just thinking out of the blue: is the car industry working on these paths?

HI Gwen !

GREAT IDEA ! it looks as though you are on your way to another patent, good luck on that, it may be a outer shell for an electric car.

thanks

OK, if anyone is interested in this I would gladly lead the feasability project. Just contact me.

Gwen

ROI two years? Which one?

I have also growing solar systems round my house, but we call them threes.

Try to split your text in sentences and paragraphs.

Strange style of formatting, one long line with everything in it, is it Chinese or so? (we see it often from Chinese people that post)

The recommendation I can make is to list the power usage in your house. look to which needs AC and the sum will be the power you need for the inverter.

An inverter will adapt the output current and voltage to the load.

The next investment for me would be to couple sun heat direct to the hot water supply.

Gwen

Thanks for the advice and why do you call them threes?

While I'm at how do you delet your question and replys

Kenn

You should start creating an account so you can be recognised, it makes the world smaller.

There are no way's to delet a responce, althow I have the possibility to alter the responce, even after it has been send.

The tree is a joke, you are growing a solar system, I found it a funny way of telling us that you install panel by panel.

gwen

Hello everyone,

While we're on the subject of misspellings. there's a spell checker on the tool-bar. It'll be a good idea to click it before you send your response. It's that check mark with ABC on top. I use it, well, most of the time. Sometimes I forget .

Unfortunately, it won't correct grammar, just spelling. Also, it won't correct wrong usage. If you say, "I dribbled the bell (instead of ball)", it will accept that as correct.

However, such things are easier to figure out than misspellings.

Good job Mr. V.

So we have seen erupted Phil....'s Vulcan

Again, thank you for a lesson for all of US.

I love your style!

By the way Does your "solar system" called trees delivers something more then just a shodow? I was in Belgium but I had not seen any sources of liquids from a tree that can be used e.g. to a gum production. AS you may see in South America.

What is the average full sunshine hours per day (annual avg #) in your city? Here we have 4 to 6 hrs/day all year long +/- 1.5 hr so we thing it is sufficient to instal PV panels.

Gretings from the East Coast of the USA

A few things need to be taken into account when thinking about any solar power system. Does it have to power any vital equipment? If so add some battery storage so when the sun is not available (night time or cloudy day) you can still draw power.

The inverter should be chosen with care there are some very dodgy units out there.

Size it to give at least 50% more than you think you will want.

The batteries must be deep discharge types not standard lead acid auto bat.

Then you require a charger control unit so the batteries are charged but not over charged. The solar panels must also give out sufficient so as to be able to fully charge the batteries even in poor light. A small back up generator will make the whole thing self sufficient and complete the work. The only fly in the ointment is the cost of all this, in the UK it is reckoned that it takes twenty years to pay back compared with using normal grid power.

HI GROUPE !

THE many replys are good but the visitor should pick up SOLAR HOME Magazine, they explain the many ways to use solar and they explain with drawings the power needed and connections to other items needed. there are past issues that can explain further with stories & photos, you'll get a good set of instructions with this magazine. by the way they have a web site where you can ask questions to the experts & get great explanations of how it works & how to assemble the project.

Right. Do not invent a wheel.

Or hot water

HI southern123 !

a new wheel has been invented it's called thin film solar ! you should look up some new companies that have come on to the solar Sean. the sun conversion is improving now and in a year or so it may be comparable to regular chip solar. oh one thing the weight is one tenth that of chip solar, so take a look you may be shocked at what you find.

thanks

goldrushnugget999

HI !

THE new wheel i talked about above is a flywheel that is levitated to preserve it's power & it can store power and run for several hours putting out that power to stabilize power companies flow of power and be used as a generator to produce backup power for factories & now the price has lowered to put in homes to do the same thing. HO ! by the way there is no need for batteries with flywheels they can maintain there flow of power for several hours, and be recharged by engine to run several hours again, over and over.

thanks

Thanks for info.

Do you know producers (addresses etc.) of the solar panels that use thin film technology?

HI southern123 !

you asked about a thin film company ! well here is one of them. POWERFILM solar

contact them at www.flexsolarcells.com/Rollable_Series.php check out the info and you'll see the 1 lb cells 20 feet long can sit on your roof or sun tracker and help you run your home and small business. ( Rollable_Series.php ) I hope this fills the bill.

thanks

Anybody knows manufacturers of Solar Panels that cost less than $4/W (four USD per Watt of its nominal output power)?
