Renesola solar panels review
Overall Rating From 70 Reviews:
Renesola is a Chinese producer of tier one solar panels with 10 year product and 25 year performance warranties. Their panels are corrosion resistant which makes them suitable for installation by the sea. Renesola has offices in both Sydney and Melbourne.
In addition to solar panels, Renesola also produces string inverters, microinverters, and LED lighting. They are also heavily involved in the development and construction of solar farms and large scale rooftop solar projects.
Renesola is a medium sized producer of solar panels. They had approximately 1.2 gigawatts of solar panel production capacity in 2015 and while it's not on their website, Renesola has informed me by email their production capacity is now 1.5 gigawatts.
In comparison, the world’s largest producer of solar panels in 2016 was Jinko Solar with a production of approximately 6.5 to 6.6 gigawatts of panels.
Renesola claims to have sold 12 gigawatts of “solar products” over the lifetime of their company, but they don’t specify what they count as a solar product.
Renesola was founded in 2005. The company rapidly expanded and claims that in 2013 and 2014 more Renesola panels were installed in Australia than any other brand. Unfortunately, like many companies that expand rapidly, they ran into severe financial difficulty which has limited their expansion over the past several years.
They currently employ around 5,600 people, mostly in China. I don’t know how many are employed producing solar panels and how many in other parts of the business such as LED light manufacture.
Renasola produces a variety of different series of solar panels, including a number of standard sized, 60 cell panels, which are the type most commonly installed on Australian roofs. They range from 250 to 285 watts and have efficiencies from 15.4% to 17.5%.
Renesola’s Double Glass Panel
Renesola produces a standard sized, 60 cell, double glass module with a 10 year product warranty and a 30 year performance warranty. But as it is a 1,500 volt panel it is not suitable for normal household installation and is made for large commercial rooftop solar installations.
In March 2016 Sinovoltaics gave Renesola an Altman Z-score of 0.23. This is a measure of the financial health of a company and their low score led me to conclude they were in dire financial straits. Renesolar has confirmed this by pointing me towards this article by Macroaxis which, on the 16th of February 2017, gave Renesola's chance of bankruptcy over the next two financial years as 40%. But Renesola would like me to point out the analysis gives many other solar manufacturers an even greater chance of bankruptcy.
On the bright side, Macroaxis defines bankruptcy as:
"Financial Distress as an operational condition where a company is having difficulty to meet its current financial obligations towards its creditors or to deliver on the expectations of its investors."
Which is a situation a company can survive, although it does make me wonder why they just didn't just call it financial distress in the first place.
Renesola produces tier one panels and so I would expect them to be reliable and unlikely to fail over the next two to three decades. While it is possible Renesola won't be around in the future to honor their warranties because of its current financial difficulties, because their panels are reliable the chance of a household needing to make a warranty claim in the first place should be small.

|The panels are rated at 3.6 kw and deliver at peak about 3.2 kw which is what I expected.
I have no issue with the panels and expect the perfomance to continue.

|We are happy with them. We have a single storey property with all 16 panels facing north with uninterrupted sun access, therefore the perfect aspect.
I have read that Samil is not the best inverter. We paid $4k for our system which is super-cheap and so far had no issues. Our last bill (May '16) was $156 for 123 days, pretty cheap. My husband wants to install batteries (acid not lithium) but I am not convinced we need it, its too early to say if we might never do it.

|Seem to be doing what they are supposed to do so far
Bought From: Solargain Southwest Review Date: 13 May 2015
|I check the Inverter readout regularly as to how much power is being produced and the amount is often at 2.5Kw plus for a 3Kw system and this seems to be acceptable according to the installer. When the system was brand new , production was often nudging 3Kw and a couple of times actually slightly exceeded it which surprised me. The supplier recommends cleaning the panels once a year, when I asked the installer the best way to do this he said he doubted the effectiveness of doing it and that he doesn't clean his own. I went ahead and did it anyway and will probably keep doing it annually but it has raised a question mark., yes

|What can I say, it is the joining of the panels and the inverter that make the system. On a good day I produce 19 kWh with a 3 kW inverter.

|Have only seen max 5KW output on a few occasions on perfectly clear days in summer. Possibly due to westerly aspect. Very low output on current cloudy winter days. Have nothing to compare with so performance may be consistent with most panels.

|Panels are fine but the installation wasn't right as one of the panels wasn't installed flat inline with the rest.
Calls to he Mark Group weren't returned.
Had to sort it myself.

|Manufacturer: Renesola Jiangsu ltd.
model: RENESOLA JC250M-24/Bb-b (60 Polycells)
Number of panels installed: 20 in two arrays of 10
I would not hesitate to recommend them to anyone to be used in conjunction with an SMA inverter.
Wish I had installed a 10KW system. (Maximum allowed under small generation systems).

|They survived a hail storm that put holes in my laser lite roofing.
Bought From: Mark Group Review Date: 2 June 2014
|12 panels facing north and 8 panels facing east - perfect array as gives a nice smooth curve of production over the day. Being in a urban/rural environment have aligned the use of power through the day to maximise use of solar generation for water pumps, garden watering reticulation system, jacuzzi heating and washing. Once batteries become affordable we believe we will nearly be self sufficient and hardly need the grid except in overcast days when the solar output falls below our requirements.
