Interesting poll results! Sol Ark VS Signature Solar

[Will Prowse]

Yesterday I ran a few polls to see what the customer support satisfaction was between Sol Ark and Signature Solar. I was expecting Sol Ark to have zero complaints, but more people had issues with them than with signature solar!


To sum up the results:

Signature Solar-
19% of voters had an issue resolved or fantastic service.
And 3% had an issue and will never buy from them again.
So 15.78% were not satisfied.

Sol Ark-
5% of voters had an issue resolved or fantastic service.
And 2% had an issue and will never buy from them again.
So 40% were not satisfied.

I am still letting the votes come in but usually it doesn't change much after the first thousand. Pretty wild results!

I wish it could give us more decimal points to increase accuracy, but these were not the results I was expecting at all.

Historically, much of signature solars equipment that is discussed here has been pretty basic compared to Sol-Arks inverter offerings. There was a lot more stuff that could go wrong or be harder to configure with Sol-Ark in regards to AC coupling, Export limiting, etc.. The newer inverter being offered by Signature Solar under the EG4 branding should be interesting, as they have relative feature parity to a Sol-Ark and might start getting hammered with those types of support issues.

One big difference is Sol-Ark holds the warranty on their inverters and ancillary products, but Signature Solar does not, at least according to the Signature Solar website.

It would be nice to know if Signature Solar holds the warranty for EG4 brand, because it seems like Signature Solar provides most of the business operations for EG4 but are separate companies.

In my opinion, this survey should be specific to EG4 inverters rather than Signature Solar because one is the actual product, and the other is a material distributor that sells 3rd party equipment.

We usually reference Solar Reviews, which verifies their reviews.

… I don’t understand statistics displayed.

Where is it displayed that the 40% are not satisfied? I'm not following the interpretation of the data here... Are these the wrong screenshots?

Have to remove all the "I don't have it" votes, and then recalculate percentages.

I didn't run the numbers to check.

This is like polling my town for a national vote.

No, it's the same company. Eg4 and signature solar. I figured that was common knowledge but maybe I should mention that more.

Is signature solar on energy sage? If so, can you post it here so we can compare them?

I did not see the SolArk poll so I did not reply as a user. Got a link? Couln't find it with simple search?

I did it on YouTube community so I could get more votes and a broader audience to poll from. Total vote count on the forum was pretty low.

An option should be:
"I had an issue and figured it out via help from DIYSolar.com"

"I had an issue and figured it out via help from DIYSolar.com"

Actually it was the user base of SolArk users on DIYSolar that influenced my purchase of a SolArk to replace my Outback inverter with a SolArk. Plus a few other features that the SolArk had.

I'm in the same boat, I purchased a SolArk because of the basis of people on this forum, as well as my installer talked so highly of them, being the only Energy Storage inverter they will ever install.

On another note, I keep seeing people telling Will to change the poll, add this, or take that out, but he can't just change the poll after its been posted and people have voted on it. It would just skew the results. Stop asking to change it.

This makes a lot of sense to me. Sol-Ark only produces inverters, whereas Sig Solar sells almost all things Solar related.

I have just found out that I may qualify for SGIP funding. If I go that route I would like to continue using a SolArk but upgrade my batteries to UL approved batteries. I see you also have DIY batteries. Did you have any issues getting inspected? I never tried because it seemed like too much hassle but I would like to get a building permit in the long run.

Who are the known players for UL listed batteries?

I did not install my batteries until after inspection ?

Only downside to this is that it is now essentially not inspected and if anything bad happens, your homeowners insurance might not cover it. At least if they think they can get away with blaming it in any way on the addition of the batteries and related hookup equipment.

I figure you are probably aware of this, but best that other people new to this stuff understand this.

This is correct. If something were to happen, then the insurance company is more likely to not cover it. Because of this, I'm trying to take extra steps to prevent damage, if in the unlikely chance something were to happen.

I wonder if insurance would deny coverage if something else that wasn't "to code", burnt the house down? Like a non-UL Listed alarm clock (not that exactly, just an example). Would the insurance company say, "Oh that wasn't up to code, you're SOL". It's kind of the same situation?

I have heard variouas opinions on that subject and some brokers I know say it is not necessarily true if an external fire envelopes the home the insurance will still cover the loss even though there may have been unpermitted installations as long as they did not cause the fire. My biggest fire risk is from wildfires sweeping down the canyons and sending embers into my attic. I am more concerned about adequate attic vents and defensible space.

I've read an answer on here or somewhere else that they cover that stuff. It's something different about hooking up non end user type equipment to your electrical wiring that does it. If it's something store bought that just plugs into a wall, it's pretty much all covered.

Basically if it's anything that would have required a permit to hook it up, and you have no permit, no coverage. At least that's how I generally understand it.

I imagine they have to prove it was somehow related to it. Hopefully they can't do so, they are certainly financially motivated to. It might not be up to them though, and entirely up to the fire inspector's report.

The resolution of your data would be much higher if you eliminated the "I have not/do not own" option, thereby limiting the poll to participation only by those with valuable information to share. It is all the "I have not/do not own" votes that are dropping your resolution on the other answers to single-digits, to where you're needing a decimal place. Something to think about in future polls!

@Techie007

Did he not just drop those from the result calcuations? If they are dropped, and the total adjusted down accordingly, wouldn't it be a non factor?
