I think it’s due to there being more fog/mist and other debris in the air in the mornings and by the afternoon it has all cleared.And west facing panels will continue to power the aircon on hot summer afternoons, after the sun has slid off the north facing array. What I mean is I’ll give you them in the form of a circle’s 360 degrees where north is 0 degrees, east is 90 degrees, and west is 270 degrees. In technical terms, this measure is called the Azimuth angle. In Summer both systems maximum production is 33.2 – 33.4 kw per day.
I live in the metro area of northern Perth. (Although the people who operate the grid don’t like it, as they’d prefer you to use more electricity when the sun is shining. While this is not a bad direction, it is often possible to get a very small boost by having them face slightly away from due north. A household can increase their self consumption of solar electricity by positioning panels so they’ll produce less energy overall, but more during periods when electricity use is high. A breakdown of solar PPAs, including how they work, how much you save - and if a PPA is the right choice for you.Learn how microinverters work, how much they cost, and how to determine if they're right for your solar system.The information on our website is general in nature and is not intended as a substitute for competent legal, financial or electrical engineering advice.

The results for both of these roof slopes will be very close to the figures below:In a typical capital you can expect solar panels facing the worst direction to produce around 28% less energy than those facing the best. So you do in fact want your panels somewhat higher than your latitude to optimize for winter and somewhat lower than your latitude to optimize for summer.You state the following and I have to wonder why tilting less in the winter would produce more electric. If you do have to pay a considerable amount to get connected to the grid then you could instead consider if it would be cheaper to increase your solar capacity.


In this post, we’ll discuss what the answer has commonly been and the logic behind it. By doing this, you are setting up your panels to perform more efficiently in the winter because they will more directly face the sun as it shines from a lower point in the sky.

The power produced by your solar system will be used by your home first and then any excess will be sent into the grid for a feed-in tariff.These charts showing panels facing various angles generating lots of electricity are fine however I am concerned that my NW facing main roof won’t start generating much electricity until after I have eaten my breakfast.When I eat breakfast I like to use high energy consuming devices like a kettle, toaster and microwave. )What is possible will depend on your roof and your wind zone — requirements are stricter in cyclone areas — but unless you live in a toadstool pretty much every roof can have more than 1 kilowatt installed on it. I’m in the process of getting solar and because I have limited roof space, the largest north-facing system I have been quoted is 4kw (13x315w panels), which would put a dent in my electricity bills but not as much as i’d ideally like.I asked the question about using the south facing side of my roof and they came back with a new quote adding 8 of the same panels for an additional $900, and going from a 4kw system to a 6.6kw.We average about 20kWh usage per day and night usage varies from very little to either a split or a couple of column heaters during the really hot/cold nights.So my question is, does the additional $900 warrant the benefits i’ll gain from adding the south facing panels?
