Solar panel tilt angle the tilt angle is the angle of the solar panels to the ground.
Optimum angle for solar panels in new zealand.
To get the best out of your photovoltaic panels you need to angle them towards the sun.
However many home owners are unsure about what makes a roof suitable for solar energy systems and whether theirs is a good candidate.
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.
For the best results solar panels should be oriented towards the south.
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 ideal angle for your solar panels can vary depending on your solar objectives.
Interestingly the optimum roof pitch angle will depend on the latitude.
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.
In this method the optimum tilt angle for solar panels during winter is calculated by multiplying the latitude by 0 9 and then adding 29.
Optimum angle differs during winter months.
Orientation of the panels.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
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.
The table below features a solar panel angle by zip code for at least one city from every state.
This solar angle calculator tells you the optimum angle to get the best out of your system.
Most new zealand homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation.
In the above case example of a latitude of 34 the tilt angle will be 34 0 9 29 59 6.
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.
The orientation of the panels and the angle they are tilted will have a greater effect on annual energy production.
