Most new zealand homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation.
Solar panel angle calculator nz.
This calculator estimates the solar energy that can be collected by a solar capture device solar panel at a given address panel direction and roof slope within new zealand.
If your solar panels will have a fixed tilt angle and you want to get the most energy over the whole year then this section is for you.
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 basis.
Similarly you can calculate the angle for winter by adding 15.
Therefore the best angle for your solar panels is the one that allows the panels to get the most direct perpendicular light.
Whatever your latitude is you can subtract 15 from it to calculate the angle for summer.
This is typically more than 10 years of sunlight hours data.
This solar angle calculator tells you the optimum angle to get the best out of your system.
For fall or spring you can just subtract 2 5 from the latitude.
What does solarview do.
Welcome to spcnz the leading solar power installation company in new zealand.
Select the pitch which best represents your roof the most common pitch for nz roofs is around 30 so select this option if you are unsure.
However the panels can be installed anywhere between 10 to 35 deg with negligible efficiency loss.
To get the best out of your photovoltaic panels you need to angle them towards the sun.
Today we re going to explain how to mount your solar panels to get the most energy from them.
Let s start with two key terms.
The orientation of the panels and the angle they are tilted will have a greater effect on annual energy production.
Solarview gives an estimate of the available solar energy at a particular location for people considering installing a solar energy system.
Both of these angles require latitude degrees.
While the sun is in a higher position in the sky during the summer and lower position during the winter it has an average position right in between the two seasons.
The program combines an image of the local landscape with irradiance data from the nearest climate station.
There are two methods for calculating the tilt angle for solar panels.
Elevation angle and azimuth angle commonly shortened to angle and azimuth for brevity.
The violet line is the solar energy per day if the panel is fixed at the winter angle discussed below these figures are calculated for 40 latitude.
The vertical tilt of your panels.
This information gives us a better idea of how much sun your panels will get.
Solar panels are generally installed at an angle so if you have a flat roof select 30.
