Solar Panel Angle Melbourne

The tilt involves primarily the angle that the panels are facing up into the sky.

Solar panel angle melbourne.

The solar radiation that the panels receive is almost the same. Well it depends based on the orientation and angle of the panels. To get the best out of your photovoltaic panels you need to angle them towards the sun. However if the panels are turned at an angle greater than 45 compared to true south production begins to decrease significantly.

As indicated in the above diagram an angle of approximately 32 is the best but anywhere between 20 and 40 is optimal for around a 90 efficiency. Generally speaking unless your roof is flat the pitch of your home s roof is going to be the angle your solar panels are mounted at. Ideally solar panels would be positioned at an angle of 38 in melbourne equal to the latitude angle of the city 37 81. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49.

In australia common roof pitches are 15 or 22 5 so your modules will most likely be mounted at one of those angles. On a flat roof the tilt is 0 whereas if the angles were to be facing a wall it would be 90. The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer. The summer optimum tilt angle on the other hand will be 34 15 19.

Solar output losses when the panel angle is not ideal. Many federation style houses in inner city melbourne have roof pitches of 45 that are ideal for capturing maximum sunshine during the less productive winter months. The table below features a solar panel angle by zip code for at least one city from every state. Panel angle the optimum panel angle in melbourne is 37 8 the same angle as the latitude of the city.

2 this seems like a reasonable way to maximise solar electricity output but because days are longer in summer it usually helps to tilt them a few degrees lower to take advantage of this. 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. Solar panel angle by zip code 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. Solar panels tilted at an angle equal to the latitude will face exactly midway between the sun s highest point in the sky in summer and its lowest point in winter.
