Designing and sizing a system properly is a critical first step, we will look at all aspects of a customer's needs. Each installation is different. You've got to customise it for the available roof space. You've got to customise it for the client's particular lifestyle, and that's not always their current lifestyle, it could be their growing lifestyle. If you're a family that's growing and you've got to choose a product that you feel comfortable with, that fits in with your budget, but also makes sense as a good investment.

It's important to size the system correctly and design it correctly. We want to size the system so it's appropriate and it's going to give the correct return on investment. If you undersize a system, the customer's not going to be able to get the return on investment that it needs. Basically, it's going to consume all of that solar power very quickly, and it's then going to have to use power from the grid. That's not going to be a good investment. By the same token, we don't want to oversize systems for customers. We don't want to have them over-invest and never be able to use that power. They're going to be feeding everything into the grid at a lower rate. That is not a good investment. When we see that a customer is going to be using in the future, potentially using in the future, they can elect on our advice to basically put in a larger system. Or alternatively with our systems, they are infinitely expandable, so we can make a much better, more informed decision a year or two down the track after they've got some solar PV performance data coming into the system. We can advise them there. Do they put extra panels on, has battery technology become affordable enough to make it a good investment?

We look at things holistically as well. So we might look at things like your hot water consumption. What are you using for your hot water? And we will often recommend things like heat pumps that will operate with very little electricity consumption, but it's using that power during the day, and effectively that's like a big battery because it's storing your hot water, but you're utilising low energy consumption and any of that energy consumption is coming during the day from your solar PV panels. When we get on site as well and you're up on the roof, there are some changes you need to make. You need to possibly reconsider the way things are done. We will pivot, if needed, on a job where necessary. If somebody has a last minute change and they want to add something, or they want to sort of delete something or change something around, we can accommodate those needs.
