This Month we have wrote a few articles in relation to solar panels, their power, and how they should be installed. This has probably lead to more confusion as it cuts though the myths and makes solar more practical for the users rather than one size fits all approach that has become a mantra of many.
Solar used to be grid tied only and therefore it was Averaged to make the most out of production year round. Unfortunately this is wildly different to what real people need solar to be. In fact it can be more than useless for most people. The actual installations should account for what system type is installed and the use cases.
When is best?
Installing solar should be fairly simple, and most will go for the easy option and then moan later. South facing on a 45 degree roof. While this approach will work for those who are abroad for winter, work from home during the day, between 10:00 and 15:00 and do nothing but sleep after and before work. ( That does sound like a lot of peoples lives, just not the holidays and short hours)…
Power demand –
This is your typical daily house hold power and south solar install usage and solar production.
As you can see the narrow peak is used up in the mid day and goes to the grid, they lose out in the morning and evening. Learn more how to not do this..
East facing, is great for those who have batteries and need to charge them from the first thing. How the angel varies ( see link above). The east face should take into account the seasonal change of the suns position at various times of the year, and the radiance. before placement. – The sun does not rise at the same time and place.
For example, Summer rise is 04:00 Winter rise is 11:00. That’s a full 95 degree H difference on the array.
To understand how solar works or not, then take a read of the the posts listed below, this will give you a better understanding of the effects and requirements of just the solar array before we move on to use cases and what needs to be viewed there.
For more information take a look thought the blog posts and here : Solar Panel installation
We looked at the following in regards to solar arrays or panel installations here is a list of the pages.
How to position solar panels
Should you use solar optimisers ( Tigos)
How the solar cycle effects solar production
How global diming effects solar
Following reading and understanding all this information, you will know how and why your solar array will be placed, the influence of weather and seasons on your solar array. Next we will work on power calculations for the inverter and your electrical usage.
