To get the best out of your photovoltaic panels you need to angle them towards the sun.
Optimum angle for solar panels in new zealand.
The ideal angle will be different in summer and winter.
Orientation of the panels.
The ideal angle for your solar panels can vary depending on your solar objectives.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
However the panels can be installed anywhere between 10 to 35 deg with negligible efficiency loss.
Most new zealand homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation.
For the best results solar panels should be oriented towards the south.
The optimum angle varies throughout the year depending on the seasons and your location and this calculator shows the difference in sun height on a month by month.
For example if you are seeking to maximise solar generation during winter months be it for an off grid system or higher energy consumption levels you would ideally want to angle your panels at a greater tilt for maximum exposure to the low winter sun.
The orientation of the panels and the angle they are tilted will have a greater effect on annual energy production.
Your life would be much easier if you could just find out what angle is the optimal solar panel angle in your city or county.
This solar angle calculator tells you the optimum angle to get the best out of your system.
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.
North solar collector solar collector should face due north ideal angles for solar collectors in new zealand place latitude summer angle winter angle.
The table below features a solar panel angle by zip code for at least one city from every state.
In the above case example of a latitude of 34 the tilt angle will be 34 0 9 29 59 6.
Optimum angle differs during winter months.
Solar panel tilt angle the tilt angle is the angle of the solar panels to the ground.
While the angle of your solar panels is important a more important factor in your energy production is going to be the direction your panels face.
