LONGi Solar Panels Range Review
LONGi are one of the fastest growing solar manufacturers in the industry, but how do their panels perform?
We’ve collected all the info you need right here to make your solar decisions as easy as pie.
LONGi offers Hi-MO 5m and Hi-MO 4m panels for residential customers.
NOTE: Don’t get these confused with the Hi-MO 5 and Hi-MO 4 series (notice the lack of the ‘m’) as these panels are more intended for commercial solar farms and grid scale projects.
Ready? Let’s learn about LONGi solar panels…
Hi-MO 4m Series
The Hi-MO 4m series is all about being modular and comes in 3 different size options. Their 60-cell, 66-cell, and 72-cell format panels are all the same width, allowing them to be mixed and matched.
This flexibility can help maximise install capacity by making full use of your roof, so they are a good option if you have limited roof space.
Gallium doped silicon helps reduce performance degradation across the panel’s lifetime. And a half-cut design helps if your roof is shaded for part of the day (although there are other options, like quarter cut panels and inverters specially designed to address shading issues also).

Hi-MO 5m Series
Everything the Hi-Mo 4m does the Hi-MO 5m does that little bit better.
While LONGi neglected to make the jump to using N-type cells for this more performance focussed range of panels, efficiency is still boosted to a pretty decent max of 21.8%.
All black options are available, but what’s really worth your attention is the 25 year product warranty that the Hi-MO 5m flaunts.
That’s a strong warranty.

How much do LONGi Solar Panels Cost?
LONGi story short (see what we did there) LONGi solar panels are going to appeal to Aussies who are after a mid-budget panel. They offer solid, reliable panels at a fair price.
If you’re after bottom dollar panels look elsewhere, but, at the same time, you shouldn’t need to take out a second mortgage to afford a LONGi system.
Remember, you might save upfront with cheaper panels, but they may not deliver you the long term savings a higher quality panel can.

*Approximate price only, AUD retail incl. GST. Assumes pairing with a comparable quality inverter. Quoted price will vary depending on multiple factors, including your location, your home and its roof, available supply, installers etc. We recommend comparing quotes form 3 installers to get an accurate price for your individual situation.
LONGi solar panels have received great reviews from customers who praise them for striking a great balance between features and affordability.
Their 12 year product warranty on the Hi-MO 4m Series is definitely not top tier, so if that’s important to you, take a look at other options, or opt for the LONGi Hi-MO 5m Series instead.

LONGi Solar Panel Warranty
There are two main things you want to ask yourself when it comes to warranties…
Can I trust my solar installer will resolve my claim?
Consider the following factors when evaluating warranties:
- The dependability of your solar professional should be a top priority. Check their reputation for after-sales assistance and customer care, just in case you need their help in the future.
- Investigate additional warranties they might offer, such as workmanship guarantees
- Ensure that your solar provider has an Australian customer support team with an easy-to-follow claims process.
- Check your inverter and panel manufacturers (they will likely be different companies) have a legitimate office in Australia with people on the ground here.
- For better service, choose a company with a longer history in Australia.
