Solar DIY Panels - Why You Should Start Using Solar Power Today!

Although saving electricity is not convenient Tyranny Liberator Review and it involves some cost, it can become really easy when you do it everyday and form a habit. It saves more of your money and it save the environment. This is just a small introduction to soldering solar cells together.

You may already know, but before we begin, it is good to remind you that there are both tabbed and un-tabbed solar cells on the market. Tabbed cells are a little more expensive, but if you are intend to build more that one panel, they will save you a heap of time, broken cells and frustration. Solar cells are very fragile, and the more you handle or mis-handle them, the greater are the chances of breaking them. Soldering solar cells requires care, and because untabbed cells effectively requires not only soldering right across a cell, there is twice the work and - well, chances are you will break some.

Tabbed cells come with the metal connector strips already attached to the front sunny side face of the cells, this strip has a free end long enough to lay across the following cell. These tab strips will connect the front of one cell to the contact points on the back of the next, and so on. Most cells are negative on the front and positive on the back and so allow the current to flow between the cells in your panel.

Why are tabbed cells good. Well, Like I said, there is a lot of work involved in soldering untabbed cells. Basically you have to solder a new metal tab strip to the front of each cell BEFORE you even look at connecting your cells together. In other words, you do a double job and that adds up to hours of fiddly work with fragile solar cells.
