I find it interesting the way the residential solar power marketing is positioned at the moment I can basically guarantee that by the time I speak with a homeowner or business owner, provide them with a quote, give them some information about what I think would be a good solution for them after asking them a few questions, they’ve usually already spoken to two or three or four other solar power companies offering a similar similar service.
Sometimes this can cause confusion because there’s conflicting ideas from competitors. So I thought with this particular install we just completed it was really important that we just looked at things from a logical point of view. Because at the end of the day, like ninety nine percent of Australian homeowners, you’re installing solar to see a financial return. And then of course the environmental benefits are a secondary thought, we will get to feel good about helping the environment with solar.
But at the end of the day, if the figures don’t work for you. You’re probably not going install solar power.
Now with this particular job, the homeowner had spoken to some large electricity retailers in Australia. And everybody was talking about micro inverters being best suited for the job. The reason microinverters were suggested it is because there were some slight shading issues. And if you take a look at the images below, you’ll see what I mean from the photos of the job. Of course shade is not ideal for solar. But it’s important that we look at the facts to determine the best solution. Thankfully through some software we use. It allowed us to do a desktop evaluation so that we were able to look at the shade at different times of the year and different times of the day to see exactly how far the shade from her large trees overshadowed her home to see how much of an effect that would actually have on the solar PV install.
So rather than just saying microinverters are the solution for all shading issues with solar. Although they would certainly not be a bad idea. It doesn’t mean it’s going to be the best thing. So we looked at it from both options. String inverter or micro inverters.
In the end I didn’t think it was going to be the best thing for the client. Especially when you consider the fact that the cost of the micro inverters would’ve increased the cost of the investment just on the Solar Inverter components by over 100%. So rather than your standard string inverter, the solarX inverters that we often use, which you can see in the images below. I mean to increase the cost by a hundred percent is by going with micro inverters thinking that it was going to solve you’re sharing issues. Well I wasn’t completely sold on that. So we use the software, did the desktop evaluations with her and concluded she would obviously get a little bit of a reduction from the solar power because of the shade. Around 12% is what we calculated. So when we weighed it up with the position their power bill and the price of electricity Solar still stacks up nicely. The homeowners should be looking at returns of around 17% pa.
So rather than spending big money on microinverters thinking that was going to be the holy grail that fixed the problem as everyone had been telling them. We installed a great sting inverter with the understanding their may be slight reduction in the performance from the shade. But who cares when the numbers stack up because the investment cost less. We can see the install is producing plenty of electricity. It’s switching on nice and early in the morning and running late in the afternoon. So the moral to this blog post is that microinverters are fantastic. There’s no doubt there’s a place for them, but at the end of the day, most of you are purchasing solar for the return on the investment and when you stack it up and look at things logically, it doesn’t always mean that the most expensive product in town, is going to give you what you’re looking for.
