Consider three questions about your rooftop and get better returns from your solar system:

When you walk into your nearest mobile store to get your mobile handset repaired, imagine yourself being asked questions about your solar panel instead of about the real problem associated with your phone (Avoid your correspondent’s reference to solar power even in an example slightly off track from the solar industry)! I would classify you as a normal person if you were bewildered and thought the salesperson was insane. That clearly defines the idea that few things are extremely basic and require no cross-examination. So if and when you’re dealing with solar power, the only thing that should concern you is your roof. And there exist three questions central to your roof in the discussion of solar power which I shall now move on to..

Question 1:  What is the ideal direction?

Solar power

To many of you this question may sound trivial. But there is much to say about choosing the correct direction for your roof. (Sorry for those who cannot help it!) To all those of you who have been promised systems by installers on south-facing roofs, I suggest you research more thoroughly or reconsider the proposal. South, south-east or south-west aren’t the suited for solar power systems. If you were to choose between East and West, I suggest you chose the latter, given that maximum electricity is consumed during the later half of the day. But the most optimum direction, which you may have guessed by now, is north. It is best suited for Australia. So having assured that, you move on to the next consideration.

Question 2: Does the angle of your roof matter?

Ensure your roof isn’t flat. If it is not, read on! Panels installed on angled roofs perform certainly better than flat roofs. But variation in the angle shouldn’t bother you much. So if your roof is angled at 15 degrees compared to your friend’s 22 degree angled roof, you needn’t bother much. As long as your roof is angled as flat roofs absorb roughly 9% less energy than pitched ones. If your installer does not recommend installing angled panels on your flat roofs, I suggest you switch to the next best alternative!

Question 3: Will a shaded roof affect your solar output?

One of the major hurdles to solar power is having a shade above your roof. All clouds, directions and the pitch become trivial if there’s shade above your roof. Don’t take your correspondent for an anti-environmentalist but the trees above your roof are the biggest devil when it comes to harnessing solar power. So next time your installer fools you for “shade-tolerant panels”, do not get fooled. These are only designed to pull light in areas exposed to less sunlight. They are no alternative, whatsoever!

Shady trees:

Now for most households, there ought to be some shade in the form of trees, multi-storey buildings or poles. The first thing you do is get an authentic installer to check it up and accordingly advise you. One of the most viable alternatives in the market is the comprehensive system called SunEye.

Investment in the drains:

And yet, if you are made into believing that there exists a better alternative than the above mentioned, your million-dollar investments is just, in the most blatant words, falling into the drains!
