    Unreliable. Had them put some panels on the house a few years back, it went fine. Last fall I contracted with them to add a battery, EV charger, and a few more panels. It did not go fine: six months later I still don't have a functional system and nobody at Alltech will explain what's going on. Alltech has either stopped caring or lost whomever the competent employees were. The main issue is Alltech doesn't bother to check if the equipment they're bolting to your house is actually compatible w/ SDG&E's infrastructure. I (no expertise at all in this area) was able to get online and see from the

    ALLTECH SOLAR IS A Rip off, and Unscrupulous, Insulting and Demeaning to Customers: Almost a year ago I hired AllTech Solar to put 20 solar panels on the roof of my 2500 square foot property in La Mesa. …

    Overall I’m satisfied with Alltech however I’m disappointed with their lack of follow through post Solar installation. The one thing they could have done better is the finishing touches. They had to break my stucco apart in in order to install a new electrical panel. After asking Ken multiple times for them to come out and repair my stucco, it’s still not fixed. It’s been almost a year since the installation. Ken keeps just telling me how busy they are and that someone will come out to fix it. It looks pretty bad and just not professional customer service.

    The whole team was great from my initial call through the planning and the installation process. I wished I found out about Alltech sooner. After years of grinding numbers and multiple estimates, "as a X general contractor myself I even considered installing my own system" Alltech came in at a reasonable install labor/material cost. Their crew was great, clean install and efficient. I wish I had a crew like Alltech when I was a general contractor. Great Guys, Great Price, Great Job. Thank You. Dan

    We had a great experience with Alltech Solar from start to finish. They installed an Enphase solar system with battery backup at our home, and the entire process was smooth and professional. The team was knowledgeable, organized, and clearly took pride in their work. Pricing was competitive compared to other quotes we received, and there were no surprises along the way. I referred them to all my neighbors and they put in several systems on our street. Chase and his team are first class. What really stands out is their ongoing support — they’ve been very responsive whenever we’ve had follow-up

    Alltech Solar did a incredible job installing my 16.1kW solar system with 40kWh Enphase batteries. Everything was handled: on-site inspection, quote, permits, So Cal Edison, city inspection, and final sign off. It was a very smooth process. The entire Alltech team was outstanding in their work and genuinely a pleasure to work with. I would highly recommend using Alltech Solar.

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.

  • Warranty

    “service. 25 year all inclusive warranty on solar power systems. Solar system…”

  • Established

    “we have been building green since 1995. When receiving a workmanship…”

Its website also mentions licensed, but not in a sentence we can quote cleanly.

Elsewhere

  • It posts on Instagram, YouTube 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.
