DIY Solar Panel System Cost

http://www.solardave.com/index.php/cost-of-a-partital-diy-solar-panel-system-video/
SolarDave: Please tell me about your solar panel system and how you saved some money?

Adam Stevenson: The total of the system and materials was $22K. I ended up spending about another $1,800 in permit fees and a structural engineer and $400 for an electrician, several hundred dollars for a guy to come help me out for the two afternoons he spent with me.

Xcel (Energy) gave me $16,538 rebate. Fix cost based on the number of kilowatts you are installing and has nothing to do with how much you pay the permit office or the electrician.

My final cost after rebate was $7,237. (SolarDave note: that is cheap!)

I started my research in solar probably about a year before I actually installed it went and got a couple of bids from some of the local solar people both from contractors that my friends have used as well as just searching the internet and while talking to one of the guys I find of developed a good feeling from him, and I asked the question “Would it be possible to do some of the work myself” and kind of learn along the way he said “Sure I absolutely support the do-it-yourself-er (DIY) so I said why don’t you throw me bids, what it would cost just come home and have solar one day and what it would cost to have it done where I do some or all the work myself. And throw them both to me and I said let’s try the second one.

The guys name is Steve Cross from Sun Spot Solar.

I gave him my electric bills and said this is how much I think I need to generate and he said I agree and lets do these types of panels 180 watts each, you will need some where around 19 to 22 we figured out 21 fit pretty well.

So I went and got all the permit information from Golden (Colorado), filled it out. He came by 1/2 hour one day he type all the Xcel application on the internet and I kind of ran the process and when I had a question I would just send him an email and he helped me out.

I think in parallel we order the equipment – he dropped off in my driveway. Then one of his installers came out and helped me for two afternoons and I pretty much myself put in the whole rack system on the roof and the installer came out and helped me kind of a two man job carrying the panels up, putting the panels down and bracketing them down.

I think we sketch out on the side of one of the solar panel boxes how they are all going to wire together so that we get three rows of series – 7 series strings so the amperage works out.

I let his installer run the conduit because that is pretty much a one person job and then I paid an electrician to plug it all in for me.

i live around there, no tall buildings around or anything. i was wondering if anybody has a house that has solar panels and if it works well and how much power it gives off. specs like that.

The amount of electricity your house could produce depends on the roof square footage thats facing the sun or that can have stands to angle the panels. Many people go for a system that gives them about half of their total usage. The actual amount per square foot can vary slightly depending on the pannels you get there are amorphous and crystaline as well as different formulations of the solar material. The best bet would be to contact a solar installer in your area for a free evaluation or for a quick look you can check out manufacturers websites like sharpsolar, bpsolar and I believe home depot also installs solar now.

How does wind power relate to life science?

I have a science fair coming up and I need to know how wind power relate to life science.

wind is related to life science because wind power creates energy and energy is what makes the world work now days. Also the wind helps life by moving spores which come from some plants, and if the spores fly then land it will grow a new plant life. also oxygen and wind to keep us cool when it is humid or hot. wind helps nature, human kind, animals and different types of life. so i guess since it helps life it’s a part of life. oh! a clouds too.
P.S. i at least sould get some credit if you us this info.

I am thinking of installing a solar trickle charger in my car. Most of them have a cigarette lighter plug-in for easy installation.

But I am not sure they will actually charge the battery. I cannot get power to the cigarette lighter plug-ins without having the key turned to "accessory". If I were to plug in a solar charger, I am afraid that it would not work, simply because no complete circuit to the battery exists while the key is not in the ignition.

There are chargers that connect to the battery using alligator clips. But these mean running a separate line to the battery. Is there a solution to this seemingly simple problem?

If your cigarette lighter works when the key if off, then yes, the solar charger will work. That will confirm you have popwer to the lighter when the key is off, thus the necessary connection to the battery.

Im doing a science fair project on windmills; how do you make the propellars and the actual windmill?

well i just made a windmill for my history project-
i made it out of a
cardboard box
paper towel roll and a
straw

P.S hoped this helped
