Optimum Angle For Solar Panels In New Zealand

The ideal angle will be different in summer and winter.

Optimum angle for solar panels in new zealand.

Optimum angle differs during winter months. 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. Solar panel tilt angle the tilt angle is the angle of the solar panels to the ground. 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 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. 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. 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.

Most new zealand homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation. To get the best out of your photovoltaic panels you need to angle them towards the sun. Orientation of the panels. However the panels can be installed anywhere between 10 to 35 deg with negligible efficiency loss.

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. Interestingly the optimum roof pitch angle will depend on the latitude. For the best results solar panels should be oriented towards the south.

In the above case example of a latitude of 34 the tilt angle will be 34 0 9 29 59 6. 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. The ideal angle for your solar panels can vary depending on your solar objectives.
