Learning about Solar Panels?

We Answered:

Magazines homepower and solar today are good sources and for building homemade solar the last site listed

Beverly Said:

I want to use radiant under my driveway. will a homemade solar panel work?

We Answered:

Depends on where you are. In Colorado, they tend to have a lot of sun, even right after a storm, so using solar water heating collectors to heat the water/glycol mix can work. But most snowy places don't get enough sunshine during snowy times to practically work.

But if you are asking if using a homemade solar electric panel, absolutely not, regardless of where you are.

Homemade Solar Panel Question - What Ebook to buy?

We Answered:

I had researched this vary same idea for several months on how to build my own solar power because my local home improvement stores wanted several thousand's of dollars to install their systems. I personally purchased 4 different books and most of them were hard to follow..I did find one that actually helped me create my own solar panels but it ended up costing me about $150 more than stated in the book because I wanted to make it look more professional since I plan on selling my house in a year...here is the link I used to find the book. Good luck!

it was the editors first choice, I think it was called greenDIY

Daes anyone know how to charge a device like an iPod or rechargeable batteries with a homemade solar panel?

We Answered:

You need enough solar cells connected in series and parallel to provide enough power (in strong sunlight) to charge the batteries.

Each small solar cell will put out a little over 0.7 volts in strong sunlight. It doesn't matter how big (area) the single cell is -- it will still only produce 0.7 volts. BUT... the larger the area, the more current you will get.

So, lets say your battery pack is 3.6 volts (pretty standard for Lithium ion packs). That means you will need at least; 3.6 divided by 0.7 = 5.1 cells in series. 5 cells will not produce quite enough voltage, so you need at least 6 cells in series to produce voltage to even start to charge the batteries (it is good to have a slightly higher charging voltage anyway). If your battery is only 1.2 volts, then you need 2 cells in series (for 1.4 volts total). If your battery pack is some other voltage, then you need to add up 0.7 volt cells until it is over the voltage of the battery pack.

Now, it becomes a matter of how much current do you want, to charge the batteries. The higher the current, the faster the charge time.

You could get one huge solar Panel that is 5 feet by 2 feet, produces 200 Watts, and you could charge your little 3.6V battery pack about 1 minute. I don't think you were thinking of that. LOL

You need to figure out how many individual cells you want to use in groups of 6 (in series), and connect those groups of 6 in series all in parallel to increase the charging current.

Then it is just a matter of connecting the positive output of the solar cells to the positive terminal of the battery, and negative to negative. Then let the sun do the rest of the work.

Since your voltage *is* slightly higher than the battery pack you must carefully watch the temperature of the batteries. When they get very warm, it's time to pull the plug on the charger.

how to make a homemade solar panel?

We Answered:

solar panels are made in large factories with exotic materials and clean rooms. No way you can make one by hand.

They put out low voltage, incapable of creating a spark.

Homemade Solar Panel - How Much Does It Cost To Build A Homemade Solar Panel

We Answered:

A solar panel with 12V electric output costs between $100-250 in the market. You can easily build your own homemade solar panel for $100 with parts you can get from the local hardware store. (The same applies to homemade wind power as well)
