Roof Pitch For Solar Panels Nz

Fixed panels are stationary and remain at the same pitch throughout the day and year.

Roof pitch for solar panels nz.

Tracking panels live up to their name they track the sun as it moves through the sky each day. Fixed or tracking solar panels. To get the best payback from solar pv you need to use as much of the solar power as possible as it is generated. 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.

Most new zealand homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation. 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. It is interesting to note however that a 7 in 12 west roof only outperforms a 3 in 12 north roof by 3 9. The bulk of solar generation is between 11am and 3pm.

There are two types of solar panel mounting options. The sun provides more than enough energy in just one hour to supply our planet s energy needs for an entire year. 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.

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. 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. Optimal electricity production occurs when solar panels face south at a tilt equal to 30. Solar pv isn t much help with winter power peaks.

Depending on the pitch of your roof tracking. The orientation of the panels and the angle they are tilted will have a greater effect on annual energy production. However the panels can be installed anywhere between 10 to 35 deg with negligible efficiency loss. Solar panels for any roof type.

Solar panels also generate considerably more power in the summer when the days are longer and the sun is higher in the sky. The angle of your roof actually has less impact on solar panel performance than the direction your solar energy system faces. It is not completely unreasonable to put solar panels on a north facing roof if the pitch is very shallow. Interestingly the optimum roof pitch angle will depend on.
