Choosing Installation Site:
The best site for installing household PV is rooftop or open ground. What needs to be considered includes coverage, housing structure and bearing weight, ground condition and weather change. For example, the bearing weight of rooftop should be over 20kg/㎡. While the wooden beam should be excluded for its life span may be less than that of solar system, say 25 years.
Specific Rooftop Style
“人”Style Rooftop
When installing PV station on this rooftop, the tilt angle don’t need to be perfect and the shadowing must be considered. Usually, the bracket will be flattened facing the south and linked with the rooftop by using klip lok. Finally, the panels are installed on bracket. It will maximize the using coverage of rooftop and keep elaborate.
Flat Rooftop
Installing on flat rooftop need to take both the best tilt angle and panel distance under consideration.
Household Open Ground
When installing on household open ground, clients could choose ground screw or concreted bar as base depending on the earth condition and cost control, and designing the strength of bracket based on the weather condition.
Most importantly, the panel size may alter micro when temperature changes, so there should be 3 cm between panels.
