OFF-GRID

Off-grid photovoltaic systems, ideal for boats, mountain huts, campers or Garage where you always need to have a voltage of 230 Vacs (batteries are excluded from the supply)

How to calculate the Watt power of 1 monochristalline solar panel with 20% yield ??
It is simple, just multiply the votal voltage V for the maximum employment current AMP,
that is p = vxi, if 18v for 5.30 amp, it will be 95 watts, or if 36v x 11 amp, it will be 396 watts
Many shop  online scene as 100 or 200w solar panels of solar panels only 40W, at very low prices,
Do not trust superlative or science fiction titles, calculate the power of the panel yourself.
If you don't know the tension and current of the panel,
Another way to calculate the coarsely power is: side x height in cm then divided 50
Example 100 cm x 50 cm divided 50 = 100W
In this way, you are sure of what you go to buy
