Why your 100 watt solar panel will only generate A 70 watts.

If you purchased a 100 watt solar kit to be taken from your battery believe that it will give 100 watts. Well, I am sorry to say it will probably only be produce approximately 70 watts of output power. If you conned? No, you have to understand the 3 important facts on solar cells.

Solar panel should be at its peak power (GPP) power generation. Most solar panels will be operated far from their MP, depending on configuration. The maximum power is generated when the load resistance is correct for the correct voltage level and current. The load is the technical term for everything that uses the power generated by the solar panel.
In an ideal system, only the device you want to be able to is the load, e.g. battery you want to reload, but in practice all the components that make the system, such as connections and wiring devices voltage, use some of this power and contribute to the total load on the system.When the system load away from the optimum load tension then the PV module amps will be away from the MEP and the solar module becomes less effective, so produced less energy. Solar panel must be entirely bathed in sunlight direct.
Most of the time that solar panel will be facing directly into the Sun, there may be clouds or shadows darken the Sun, and it can be any debris on the solar panel obstruction in the light of the Sun. In a 100% efficient solar module, the Sun fall on an area of one square metre of solar panel would produce 1000 watts (1 kW), but average PV Panel is approximately 15% efficient and produces approximately 150 watts (15% of 1000) per square metre of surface. Solar cell temperatures should not exceed 25?C. Excessive heat has the greatest effect on the voltage generated by the cells. Do not be fooled by the ambient temperature, because when the air is on 10?C, the solar cell will be on 40?C. Solar cells don't like heat, when the temperature rises, then the cell produces less tension.A cell is producing voltage of 10% less than the etc. 25?C a typical day of summer, the cell can be 65?C to 40?C .and 80 watts rather than 100 watt output.

Conclusion. All these factors add total loss of the system energy solar generation.Use thicker rather than of the fine to reduce losses of power and surchauffe.Les controllers solar MPPT will receive most of your solar panel power. Deep stacks are better than car storage batteries and the use of electricity.
