Installer profile
Alternative Energy Systems
The history here is real. The exact CSLB entity is Alternative Energy Systems Inc, license 853351, a current and active corporation with C-10 Electrical and C-46 Solar classifications, issued January 21, 2005 and expiring January 31, 2027, based at 13620 Hwy 99 in Chico. The company timeline starts with founders Lance Mc Clung and Tim Hamor installing their first solar system over Thanksgiving weekend in November 2003; both men remain the license's qualifying individuals and 10 percent or more owners. AES became a SunPower residential Master Dealer in 2013, one of three, won SunPower dealer awards in 2015, 2018, and 2019, and in March 2018 became the North Valley's first locally owned Tesla Powerwall Certified Installer. No publicly disclosable CSLB action appeared on the record when it was read.
One complaint drags the grade down, and it is how the company handled it that matters. BBB rates AES B-, and its stated reason is failure to respond to one complaint. The March 12, 2024 complaint alleges that during a mid-December install a worker sliced through the wire connecting the customer's hot tub, the cut cord sat in pooled water and short-circuited the house, the customer lost a standing freezer and an outside fridge of food, AES workers acknowledged fault after two outlet replacements failed to fix the garage power, and compensation promised by upper management never arrived after almost two months. The status is Unanswered, meaning the business never responded to the dispute. This is a consumer allegation, not an adjudicated finding. But one property damage complaint in three years is survivable; ignoring it is a choice, and BBB priced that choice at a B-.
The remaining evidence is thinner than the 22-year history suggests. A company blog post claims "an exceptional 25-year warranty that covers not only the solar panels but also the components and installation," but no obligor or exclusions appear on that page, and blog copy is not a warranty document. AES appears in none of the three Solar Power World lists reviewed, so volume rests on its own timeline: a Fall 2015 partnership with All Solar Electric of Yuba City to expand into the northern Sacramento area, and a 2022 public works contract covering five Tehama County sites. Worth a quote if you are in the North Valley. Bring two demands to the table: the actual 25-year warranty document, and a written answer on how they handle damage claims, because the one public test of that went unanswered.
The evidence
The company timeline dates its first solar install to November 2003, BBB records a business start of October 1, 2003 and incorporation on September 29, 2004, and CSLB issued license 853351 on January 21, 2005, a tight, consistent progression from first job to state license that supports the two-decade history.

No complaint disclosure link displayed on license 853351 when read on August 26, 2026, and no government enforcement was found in the searches run, but BBB rates the company B- with the stated reason of failure to respond to one complaint: a March 12, 2024 filing, status Unanswered, alleging a sliced hot tub wire during a mid-December install, a short circuit that cost the customer a freezer and fridge of food, acknowledged fault, and promised compensation that never arrived, a consumer allegation the business did not answer rather than an adjudicated finding.

AES is absent from the populated 2026 Top Solar Contractors, 2025 Top California Solar Contractors, and 2026 Top Solar Installers tables, and while the company timeline cites a 2015 Yuba City expansion partnership and a 2022 five-site Tehama County public works contract, no independent install count or megawatt total verifies scale in this evidence set.
CSLB lists Alternative Energy Systems Inc as a current and active corporation with C-10 Electrical and C-46 Solar classifications under license 853351 expiring January 31, 2027, backed by a $25,000 Western Surety contractor bond and Midwest Employers Casualty workers comp running May 1, 2026 to May 1, 2027, with qualifying individuals Robert Lance Mc Clung and Timothy James Hamor each certifying 10 percent or more ownership.

A company blog post says AES offers an exceptional 25-year warranty covering the solar panels, components, and installation, but the obligor and exclusions are not stated on that page, so ask for the actual warranty document with named coverage before signing.

How to read this
This grade weighs a long clean state record against a short ugly service record. The license side would support a B on its own; the unanswered 2024 complaint pulls it down because non-response is the one part of that story the company fully controlled. The grade does not mean AES does bad installs, and it does not mean the complaint's allegations were proven. It means that when the one public test of accountability arrived, the company went silent, so get every promise, warranty, damage handling, and timeline, on paper. Our full rubric, including how our own installation business gets graded on the same scale, is on the methodology page. We are a solar installer and we partner with other solar companies. Grading is structurally separated from revenue; see disclosures.
