Do you have information about a solar and wind generator combo?

We Answered:

You can build a system that consists of solar panels and a wind powered gererator. In this case you can use whatever windmill you like and whatever solar panels you like.

how to hook up a solar panel directly to meter without using batteries?

We Answered:

you need to purchase an Inverter which converts the DC from the panels to AC. The inverters are fairly pricey so check around. A good inverter will have a 10 year warranty. The panels have a 25 year warranty, but should last 40 years with no problem. Just make sure you clean them on a regular basis and if you live in an area with hard water, make sure you squeegee the water off, or the minerals will build up on the panels and lessen their efficiency.

where do i find information on how to build and operate a solar panel?

get the solar cells
check power and ground
When you look at the solar cell, make sure you check voltage between the positive side (the back side which is usually grey) and the negative side (which is the black side, with all the lines on it) of each cell. You can simply use a multimeter by placing its leads on the cell itself. This step is crucial, otherwise you'll connect bad cells in the middle of your link, causing the whole panel not to work.
use conductive pen if needed
You need to make sure that all the tiny little lines in the negative side of the cells are interconnected (a way to gather all the electrons from the surface). This step is not necessary for all cells, only for the ones like in this picture, which don't have any connection between the lines on the surface. you can use the conductive pen to draw a thin line which connects all of them. Once you do that, you will immediately see the voltage rising for that specific cell.
cell with conductive pen line
here's an example of a cell with the conductive pen line on it, linking between the tiny conductive leads on the negative side of the solar cell.
linking the cells
This can get a bit tricky, but once you get the hang of it, can be done fast enough. First, some technical notes: In order to get higher voltage, you need to connect two cells in series. This means that the negative part of the first connects to the positive part of the second. As you continue to add more cells in series, you will get a higher voltage from side to side on your solar strip. This is all good, but if your cells are small-ish, they won't generate much amperage. So even if you have a high voltage, you probably won't be able to give it any load (probably will hardly light an LED). In order to get higher amperage through the circuit, you need to connect cells in parallel (positive side to positive side, negative side to negative side). When you do this, make sure the positive and negative leads (copper mesh in this case) don't short themselves out.
I found that the best way to connect between two cells was to use hot glue and some conductive mesh. The mesh is good since it allows light to come through it, and we all love glue guns. So all you need to do is glue the mesh onto the solar cell surface. Its always better to have a longer strip of mesh on the surface, with a big enough shared surface space between the two. Always check with a multimeter that there is connectivity, and that there is voltage coming through. Its a bummer later to try and figure out where the problem is.
silicon coating
I highly recommend applying a silicon coating to your solar array. The cells are so fragile, and the links can easily detach or move out of place. A thin coat of silicon keeps it all in place... and also gives it a very cool effect!

Unless you have a lot of special equipment and chemicals, you can't make one yourself, you have to buy one.
