Between a cheap panel and a decent panel on a commercial property, can be a very short payback period, so six months 12 months extra. You've got a panel that's going to last 25 years, compared to a panel that's going to last 10 years. So they get drawn in by the initial price, when should they should really be looking at the overall long-term investment and payback. Commercial clients really need to look at the quality. Adding a higher efficiency panel, where you can fit more panels on your roof. So it's allowing you to squeeze the biggest system possible onto that roof space. So you're reducing your costs and helping the environment at the same time, which is a win-win for everyone.

They should be looking at the return on investment of the system over the 25 year period of the warranty. Which if you're changing the panels after 10 years, there goes all your return on investment. So look at the panel you're putting in, make sure it's quality because in the long run you'll be the one that's paying for it. Design and sizing is very important, especially on a commercial job, if we're looking at peak loads and trying to minimise their energy consumption. So we spend a lot of time analysing these bills to get the right outcome. Getting the interval data from the retailer. Looking at the, their loads. Putting data loggers in prior to the installation, to work out the loads that they're using and what times of day. Looking at their operation hours to maximise their system performance, and minimise their electricity bills.

With the return on, we've got a return on investment calculations, we add each bill, we'd analyse and put into our system and we calculate their return on investment for each project. The biggest driver for commercial customers is to reduce their operating costs. It's a considerable cost to their business, for their outgoings. We've had customers who've had multiple commercial properties upwards of $50,000 which are now only paying under a $1,000 to $2,000 a year. So their return on investment has been two and a half years. It's not hard to do the numbers, and financially it makes sense for commercial customers to put solar in.
