Ideal Solar Panel Angle Nz

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.

Ideal solar panel angle nz. This decline is due to the fact that solar panels during most of the day are exposed to weak and not perpendicular sunlight. In order to collect energy more efficiently solar panels should be angled to face as close to the sun as possible. The authority on sustainable building. At 90 from true south therefore east and west production can drop to 30.

It s important to select the solar panel that is best suited to your budget and electrical needs. To get the best out of your photovoltaic panels you need to angle them towards the sun. The vertical tilt of your panels. Let s start with two key terms.

A highly efficient solar panel comes at a premium price. The efficiency of most solar panels available in new zealand range between 15 to 21. The ideal angle will be different in summer and winter. Today we re going to explain how to mount your solar panels to get the most energy from them.

Most new zealand homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation. Photovoltaics produce power when the angle at which the sun s rays hit the panel surface the angle of incidence is small or when light strikes the panel as close to perpendicular as possible. Use one of these formulas to find the best angle from the horizontal at which the panel should be tilted. Elevation angle and azimuth angle commonly shortened to angle and azimuth for brevity.

If it s standing upright perpendicular to the ground it is at a 90 angle. The solar radiation that the panels receive is almost the same. Solar panel angle is another way of describing the vertical tilt of your pv system. A panel covered in snow produces little or no power.

Calculating the ideal angle for your solar panels is not that difficult. However if the panels are turned at an angle greater than 45 compared to true south production begins to decrease significantly. Latitude and the season. It just depends on where you live.

If your latitude is between 25 and 50 use the latitude times 0 76 plus 3 1 degrees. As new zealand is in the southern hemisphere the solar panels produce most power when they are pointed directly at the sun i e. If your latitude is below 25 use the latitude times 0 87. As a general rule of thumb keep in mind that the panels need to be more vertical during winter to face the lower sun directly and more tilted towards the ground during summer to face the higher sun.

Angle of latitude angle of solar collector in winter angle of solar collector in summer 15 in winter 10 in summer north solar collector solar collector should face due north ideal angles for solar collectors in new zealand place latitude summer angle winter angle whangarei. Solar panel tilt angle the tilt angle is the angle of the solar panels to the ground. This solar angle calculator tells you the optimum angle to get the best out of your system.
