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.
Solar panel angle calculator nz.
Solar panels are generally installed at an angle so if you have a flat roof select 30.
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.
This is typically more than 10 years of sunlight hours data.
Let s start with two key terms.
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.
Whatever your latitude is you can subtract 15 from it to calculate the angle for summer.
Welcome to spcnz the leading solar power installation company in new zealand.
The orientation of the panels and the angle they are tilted will have a greater effect on annual energy production.
Both of these angles require latitude degrees.
The program combines an image of the local landscape with irradiance data from the nearest climate station.

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.
Therefore the best angle for your solar panels is the one that allows the panels to get the most direct perpendicular light.
This solar angle calculator tells you the optimum angle to get the best out of your system.
Welcome to another entry in our ongoing solar 101 series.
However the panels can be installed anywhere between 10 to 35 deg with negligible efficiency loss.
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.
What does solarview do.
The vertical tilt of your panels.
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.
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.
Similarly you can calculate the angle for winter by adding 15.
Most new zealand homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation.
There are two methods for calculating the tilt angle for solar panels.
Solarview gives an estimate of the available solar energy at a particular location for people considering installing a solar energy system.
This information gives us a better idea of how much sun your panels will get.
