When I purchased a new home in 2016, I had two choices: buy a solar panel or lease it. I was stupid enough to purchase it. Now all microinventors failed due to the power outrage, and Sunpower refused to warranty all these. I have to pay $2000 to repair them. Also, they claimed to add a surge protector which protected the power surge during the power restore. HOWEVER, Sunpower still refuses to warranty even if the surge protector is in place. As you know, the power interruption will be occurred by SCE frequently. The microinverters under the solar panel will go out every time it happens. You will have to pay more than $2000 constantly. DO NOT GO WITH SOLAR PANEL.

One our panels stopped producing after 4 years and we turned in a claim to Canadian Solar. They came back and told us they would give us $76 instead of a replacement panel. In the fine print, they state they can do that instead of a replacement panel. They still brag about their great warranty coverage. Don’t believe it! Go with a better company that will back up their warranty!

We got a bad batch of panels (installed in 2013-2014). Getting Trina to send new panels took 1.5 years. I'm not sure if the breakdown was our solar service company (solar service help), or installers (Verengo - now bankrupt and sold assets Crius) or Trina but there's no reason it should have taken 1.5 years to get new panels.

It seems sleek, fits our roof and style well with the dark black/navy blue appearance and has been making clean energy as expected.

I installed 33 AXIPREMIUM X HC 400 watt panels after doing much research on quality, performance, warranty, and price and the Axitec panels stood out. Also, the German engineering was a factor. I've had them for almost a year and they have performed better than expected with ZERO issues-which is what you want. The customer service at Axitec is great too---I had questions and they were more than willing to help. If I buy more panels, they will be Axitec.

Mission panels rock,
over 1 month
In operation in N. Ft. Worth, TX almost 2-yr. Operational data exceeded design expectations by a wide margin. The system (panels, inverters & the physical plant) has been stable & reliable with only one inverter replacement early on (an infantile failure). On the financial side; the monthly note came in 20% lower than utility averaging. So the money worked out too.

A recurring point we make on SolarReviews is that solar panels last a long, long time; 25-30 years to be exact. This makes it important to buy solar panels with the following qualities:
They are the least likely to fail.
This third point is very important in practical terms, and a good reason why it is not always wise to buy solar from the cheapest company.

The concept of an elite list of Tier 1 solar panel manufacturers was first used by Bloomberg New Energy in a report on the "bankability" of different solar panel brands.
They chose brands that had been financed on a non-recourse basis by several banks, over several different projects greater than 1.5 megawatts in size.
While Bloombeg’s definition of Tier 1 is somewhat useful, in our view it’s insufficient as a guide for consumers. It only judges the solar panels based on past performance, and doesn’t attempt to predict the future reliability of each manufacturer.
Given that solar panels last 25-30 years, we think much more weight should be given to the future prospects of the brand, as well as the manufacturer’s future economic viability.
The editorial committee of solar industry experts here at SolarReviews came up with our own definition of a Tier 1 solar panel brand.
We used six criteria, and we encourage you to use them when evaluating any solar panel brand. Here they are:
Many second- and third-tier solar panel manufacturers that are based overseas — usually in China — do not honour their warranties.
They sign up a few dealers in America over the internet by offering cheap panels, but if there are any warranty issues they pin the blame on an "installation error" or a "cosmetic defect" that isn’t covered by warranty. As these companies invest little to nothing in their brand in the US, they have nothing to lose. Often they will simply start selling panels under a different brand.
Among these companies are also those that buy B-grade cells and wafers, and build panels out of them for cheap sale. Many of these smaller overseas companies also outsource large parts of their production to the cheapest contractor in China, and so it is impossible to get a gauge on real manufacturing quality.
There are now very few US solar panel manufacturers.
Leading US manufacturers SolarWorld, Suniva and Silicon Energy have all gone broke, while market leader SunPower has moved most of its panel manufacturing to Malaysia, the Philippines and Mexico. Tesla has also closed their planned solar panel manufacturing plant in Buffalo, New York.
Ironically, the only well-known solar company with large-scale manufacturing in the USA is the Chinese solar giant Jinko Solar, who have a factory in Jacksonville, Florida.
We do know of two smaller brands that still make their panels in America: Mission Solar in Texas, and Washington-based Itek Energy (now owned by Canadian company Silfab). However, they are small manufacturers and we are unsure of their current production arrangements or volumes.
Although the Trump administration attempted to boost US manufacturing of solar panels by imposing tariffs on Chinese modules in 2018-2019, American-made panels have unfortunately been unable to compete with the low cost and high quality of Chinese and other imports.
It can be useful to sort manufacturers into groups that share common traits:
This is a group of mainly Chinese solar panel manufacturers that are dominating the global solar panel market. They have not had the same success in the residential US solar market, although they are steadily growing their market share.
This category includes manufacturers like LONGi Solar, Canadian Solar (actually a Chinese company), Trina Solar, Jinko Solar, GCL Group, Risen Energy.
Their best panels are currently 1-2% less efficient than SunPower, but this looks set to change. Both Trina and LONGi have announced cell technology improvements for Fall 2020 that offer equivalent efficiency to the premium manufacturers, but at a lower price point.
While we have concerns about the lack of financial transparency from some of these Chinese companies, their lower price point, improving technology and massive manufacturing scale may make them as reliable as the premium brands.
SolarReviews takeaway:
You are very unlikely to have any problems with the solar panels from either the premium brands or these Tier 1 Chinese manufacturers. The decision is
probably whether you want to support a Chinese company to save money on your solar system. We can see many good moral
arguments why one may not wish to do this.
There are many other smaller brands of Chinese solar panels — we recommend that you avoid them.
The reason is that the high quality Tier 1 Chinese brands above are already quite low cost, come with some transparency, and place some value in their brand. As such, they offer good value to homeowners.
With the smaller Chinese brands, by contrast, there is no transparency. We’ve seen several of these companies simply shut their presence in a country when faced with warranty claims.
SolarReviews takeaway:
Buying from these manufacturers means lower chances of getting quality panels or seeing
your warranty claims honored. The small upfront savings you can get from these panels simply isn’t worth it.
