Equation with Theoretical Numbers (none / 0)
If I get 2 KiloWattHours (KWH) per hour then in North Little Rock (where I live) I  get 11,700 of sun a year so I would get 23,400 KWH of energy minus obstructions.  The price for electricity is around 10 cents per KWH(A little over 11 right now, but the average is SUPPOSED to be 9.7 so I'll go with the easy number a little over it.)  This means I have to divide by 10 if I want to get dollars.  So it's obviously $2,340 a year where I am minus cost of obstructions.(If it doesn't move then time of shade, If I don't clean it then dirtiness, I can't stop the clouds, and any form of partial eclipse... I'm sure there are more and will keep trying to figure them in.)

If we could find a way to buy in bulk it's a lot cheaper I'm sure.  I'm going to call these guys
http://sunelec.com/index.ph p?main_page=index&cPath =32 tomorrow to see what I can talk out.

If we use the prices of $0.61 per watt, (I heard $0.85 was supposed to be good) then we could get an idea of what it should begin to cost when it all comes together.

It takes 1000 watts to make a kilowatt.  So it takes 1000 watts activated for an hour to make a kilowatt hour or KWH.  To get 2 KWH per hour you would need 2000 watts of solar paneling. You can find the cells cost by multiplying by it's price per cell.  Since 2000 x .61 is 1220 you know it's precisely $1220.00 to buy the solar cells (Not full panels yet) to get 2KWH per hour.

So add that with other costs and obstructions subtract from $2,340 to find out precisely how much ground you'll cover in the first year.  (Of course I know some of these things like the weather can't be predetermined, but we can resort to the almanac and meteorology to ball park it.)

So far I've got $2,340 - 1220.00 + $165.00 for inverter and ? for all other costs and obstructions, lets try to figure out and or delete as many of these as possible

If anybody knows why this wouldn't work for solar from battery to house please tell me.

here we go. (none / 0)
this is where i bought my systems. they use a grid intertie system which is pretty easy to set up. basically plug and play. the grid intertie bypasses the need for a battery. the energy you get goes directly into your box and the grid. so if on the off chance you make more electricity then you use the power company has to PAY you at THEIR rates. basically anytime you produce power it sends that power into the grid, since the elec company has to pay you for that power they just deduct it from your bill, penny for penny. as for the inverter i just used the one they sent with most packages tho they do have some options there.

now for the angle of the sun this is a good diagram you can use. to figure out the angles on different day's of the sun you just need to realize it goes around the sun and the sun's rays always come in horizontal (in accordance with that diagram). now note the angel of the earth's tilt is, 23 and a half degree's, that diagram is at summe solstice, so for winters solstice the earth would be 23 and a half tilt to the left, instead of the right. which means across the year the total degree of change is 57 degree's you divide 57 degrees by 365, and that's how many degrees worth of change you get per day. from there you just use some trig and your location on latitude(or was it longitude, i always mix those up) to figure out the angle of the sun.

dude i suck today. (none / 1)
the first link there is to the place where i got my own solar and wind systems. i forgot to paste the link for the sun diagram duh.

THANK YOU! (none / 0)
Now we are really getting some where.  I haven't slept in a little over a day, so I should probably give my brain some sort of rest before I do so much.  Though from what I see it looks very promising!  I will get on that as soon as I have any free time.  Thank you again.

You know what. (none / 0)
This is a very good example of supply and demand coming into effect for time to buy.  If you look at the most expensive solar paneling at http://sunelec.com/ will end up being about 3/4s the price.  I'm not an expert on this or anything, but I'm pretty sure these guys are betting on changing the market.  I want to make sure they do it.

ea those guys. (none / 0)
i had tried to buy from them originally i almost forgot. but back when i bought my stuff they had issues with shipping to canada so i wasn't able to purchase from them. as you can see in canada solar power is even MORE expensive. sad really. might also be because our energy companies dont use solar at all because of how north we are. i know enmax (energy company where i'm from) uses a decent percentage of wind power but no solar as of yet. and if no energy company has any demands for solar panels then production of them would be low.
