And by 6 6kw what i mean is that there s 6 6kw of solar panels installed on the roof with a 5kw inverter.

A present day 5kw solar system will need about 30 40 m2 of roof space depending on the wattage of the panels. In practical terms a solar panel system with a total rated capacity of 5kw kilowatts could be made up of either 20 250 watt panels or 16 300 watt panels. Average solar panel cost. How many solar panels does a 5kw solar system have.

5kw or 5 kilowatts is 5 000 watts of dc direct current power. But solar suppliers and their customers have done the maths and worked out that going 6 6kw can be better value.
