However even if you lower the tilt of your roof all the way down to 5 production only decreases by about 10 percent.
Roof pitch for solar panels nz.
The orientation of the panels and the angle they are tilted will have a greater effect on annual energy production.
Your home can capture this free abundant energy source through rooftop solar tiles turning sunlight into electricity for immediate use or storage in a powerwall battery.
However the panels can be installed anywhere between 10 to 35 deg with negligible efficiency loss.
At the end of the day if you really want to install a solar panel array on your roof there will always be a way.
Most new zealand homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation.
If the natural structure and materials of the roof are not suitable for an efficient system there are many ways in which you can adopt a roof to meet the requirements.
It is interesting to note however that a 7 in 12 west roof only outperforms a 3 in 12 north roof by 3 9.
In a sunny country like new zealand having solar panels is a great way to become more self sufficient and to reduce your energy bills.
The bulk of solar generation is between 11am and 3pm.
There are two types of solar panel mounting options.
Fixed or tracking solar panels.
Optimal electricity production occurs when solar panels face south at a tilt equal to 30.
The angle of your roof actually has less impact on solar panel performance than the direction your solar energy system faces.
Interestingly the optimum roof pitch angle will depend on.
Solar panels for any roof type.
The amount of customization.
However many home owners are unsure about what makes a roof suitable for solar energy systems and whether theirs is a good candidate.
Fixed or tracking solar panels.
Solar panels also generate considerably more power in the summer when the days are longer and the sun is higher in the sky.
Tracking panels live up to their name they track the sun as it moves through the sky each day.
Depending on the pitch of your roof tracking.
The sun provides more than enough energy in just one hour to supply our planet s energy needs for an entire year.
Solar energy production drops off quickly especially as the roof pitch increases.
Solar pv isn t much help with winter power peaks.
