5> Techinical points of Solar Panels

• Power Tolerance

This refers to the percentage variation in the panel’s power production. A positive power tolerance means that the panel will produce at or above what it is labelled. E.g. a 200W with a 5% positive power tolerance will produce anywhere between 200W and 210W. The same panel with a negative power tolerance will produce anywhere between 190W and 200W.Solar cells with a positive power tolerance are selected by higher quality manufactures and generally indicates a higher quality panel.

• Temperature Co-efficient

As counterintuitive as it sounds; solar panels don’t work as well in higher temperatures. A measure of how much production a panels loses once it gets hotter than 40 degrees is the Temperature Co-efficient. For every 1 degree over 40 degrees, Suntech panels for example will lose 0.45% production – This is around what most panels lose so don’t be too concerned plus this is factored into the productions figures given for each city.When looking at panels, go for one with a lower percentage or temperature co-efficient as it indicates a better quality panel.
