And that would feel like working for CSIRO again. In principle, this seems simple enough, but how far should you space them?If you set them up in Winter, you don’t want to need to relocate them in Summer, right? You chose the *Basic version of the Solar Panel Shadow Calculator.So, you’re setting up a solar panel array. I’ve got a flat roof verandah on 2 sides of my house, and both have a slight slope that is barely discernable to the naked eye.Dunno about ground mounted panels. Great idea!

It would take all the fun out of it. Shadow Analyzer expresses in graphs and tables the daily, monthly, and yearly profiles of many useful energy characteristics of the solar equipment from the daily energy losses associated with shading of individual solar panels to the annual energy yield of the entire solar installation. I pause it just before the shadow hits the panels at 6pm.You can see that the shadow cast by the new house starts to hit the panels at 6pm. We’ll send you an email report with contact information each time your calculator is used.Gain valuable insights with real-time statistics and analytics for your calculator. Its well worth putting in the analysis effort up-front, you’ll get a much better idea of what will occur as you change things.Sue.. Do the research on Finn’s site.. A wonderful wealth of information and support… . Next, Shadow from obstacles (buildings, vegetation, other (roof) installations) has its effect on the Global radiation at the solar module and so more shadow from obstacles leads to a higher PR? Shadow from one row of solar panels on the next row(s) has its effect on the expected generated PV energy and so more shadow from panels on other panels leads to a lower expected PR? Simply enter:And our calculator will tell you, in feet, how long the shadow cast by your panels will be. Depends on how much vacant space you have left on your block. I couldn’t bear the thought of an expertly-installed LG solar system being compromised – so I promised to whack together a rudimentary analysis over the weekend. Shading analysis is a very crucial step in finalizing panel locations in distributed Photo Voltaic (PV) solar installation. I can imagine Chris would be most relieved with that result. Your neighbours will not be happy if, during a cyclone, a row of 12 ground mounted panels gets ripped out of the ground due to the force of wind hitting it from the rear, and it lands on their roof or hits the side of their house traveling edge-on at a speed of 150 kph. Also – different sections of the flat roof may well slope in another direction ( you don’t want ALL of the water that lands on the roof to only flow to a set of down-pipes on only 1 side of the house.) I haven’t worried about any other detail. Fill-in your panel details (see your solar panel data sheet).Click on the surface on your model where you want the panels to go.

He may be sceptical of my calculations. We did a trade off and decided to maximise our number of panels to cater for any loses and it was the right decision….. Colin from Melbourne.If you have 3D imagery in your part of Australia – the shading engine can give you a good estimate of when shade will hit your roof:I am doing a very similar analysis right now because a (gigantic) childcare centre is being proposed to the north of our house.

I want to install panels but we have a 2 story house going up behind (to the north). But I’m getting distracted… What Chris needed was a ‘shade analysis’ or ‘shadow study’.
