What reviewers said

I visited the GreenTech Renewable Hyvard office on Monday, December 29. There were four people waiting in line and not a single employee at the counter. It was freezing inside, and nobody was working. This is not a one-time issue — it happens all the time. You always end up waiting, and then incompetent salespeople who don’t really know what they’re talking about try to sell you something. For comparison, the San Jose office is like night and day. There is always staff at the counter, everyone greets you, and they genuinely try to help and solve your issues. Fast, professional, and respectful

The worst Greentech I have been to. Even when I will call the day before, I always have to wait at least an hour and half for the material. Also their employees there don’t care at all. And this happens to me always so I decided to never will call this location.

While driving out of my neighborhood in San Jose, THIS vehicle made a left turn into the street and parked, blocking my way. The driver excited laughing and said “it’s not my fault it’s a small street.” He then told me he didn’t care if I called his company because he would not get in any trouble. I am a disabled person and would NEVER hire a company that uses such horrible staff!

Park your truck outside the facility and the check-in has a big sign “Will Call”. Nice employees and very fast loading/unloading. They can take your load even before the appointment date and time but make sure to call them beforehand. To dock, you need to reverse all the way in the company and then dock.

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

What the company says about itself

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

Its website also mentions 24/7 availability, but not in a sentence we can quote cleanly.

Elsewhere

It is also reviewed on Yelp. Worth reading before you sign anything: those are a different crowd, and the complaints that reach the Better Business Bureau rarely reach Google.
It posts on LinkedIn, Instagram, YouTube, X and Facebook. A page that stopped posting years ago tells you something a listing will not.

As Google published them when we last read the listing, not a live check. Ring before you drive anywhere.

Who Google shows alongside them

Google’s own “people also viewed” set, in Google’s order. It is Google’s comparison, not ours.

The ones without a link have no page here, either because Google does not categorise them as solar businesses or because we could not match the name to a listing with confidence.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

What we don't know

The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
