How To Tell Solar Panels Apart From Each Other

You could use a voltmeter or a multimeter setup to measure voltage.

How to tell solar panels apart from each other.

Photo voltaic basics impinging sunlight creates a potential difference between the two sides of a solar cell and when you connect these sides with a conducting wire a current will flow. As a general rule thin film panels look more uniform and some feel these look best although they take up much more space due to their lower conversion efficiencies and aren t widely installed in australia nowadays. To have an excellent performance from our solar power system it s important that the panels do not shade each other that they have the same angle and that they are positioned away from possible causes of shading such as trees poles or various protrusions. Monocrystalline solar panels have solar cells made from a single crystal of silicon while polycrystalline solar panels have solar cells made from many silicon fragments melted together.

The main difference between the two technologies is the type of silicon solar cell they use. If you live below twenty five degrees latitude your solar panels will need to be tilted towards the sun in the amount of latitude number. The diy solar set up. Make a remote 120v dc stack of solar cells and use switch mode power supplies to get lower voltage dc.

Of course in case of shading due to climatic conditions there s not much that can be done. To convert the solar cells power to ac so you can have batteries near the cabin then back to 12 or 24v dc then back to ac to use appliances introduces more inefficiency. But be careful as solar panels output a large direct current even for 24v. Some people choose the look of certain types of solar panels to others this is just down to personal preference.

These different stringing configurations have different effects on the electrical current and voltage in the circuit. Typically solar panels perform best on south facing roofs with a slope between 15 and 40 degrees though other roofs may be suitable too. In my mind better to convert once. One of the key differences to understand is stringing solar panels in series versus stringing solar panels in parallel.

If you re someone new to the idea of installing solar panels this should be a great read for you. The size shape and slope of your roof are also important factors to consider. If you live at twenty five degrees latitude you will tilt your panels by twenty five degrees. After twenty five latitude add five degrees for each additional five degrees of latitude up to forty degrees.

But this tutorial takes some of the fear out of creating your own solar panels. There are multiple ways to approach solar panel wiring. The emphasis here is on efficiency. Other things being equal that would cause losses on 24v to be half those on 12v.
