We do quite a bit of work up in the hills, with the hills comes a lot of trees. So we do have a lot of partly shaded sites that we designed, so use of power optimisers with the panels worked very well. So we can have a partially saving site that still produces, where a string inverter wouldn't. Power optimisers is a good solution for these partly shaded sites. With older houses and different roof angles, the power optimisers or the micro inverters really come into effect because they open up the design for the property. We can make it work with the use of the either the power optimisers or micro inverters.

The designer at the end of the day will make a decision on what sized system, what inverter, what panels, to suit the customer. So if you get that wrong, you could have a system that is is not right or fit for purpose. With design it really comes down to spending time with the customer and going through all of the time of day which they're using the electricity. Spending that time with the customer, to get the best outcome for them. If you're not spending time with the customer and going through this, it's quite difficult to come up with an outcome that's going to be beneficial.
