Exhibit 99.1

Polar

Power Receives Trial Order for 50 Propane-Fueled DC Generators from Major Southeast Asian Telecom Operator

Initial

order potential first step to a multi-year deployment program.

GARDENA,

Calif. - September 29, 2026 - Polar Power, Inc. (Nasdaq: POLA) (“Polar” or the “Company”), a designer and

manufacturer of high-efficiency DC power systems for telecom and other mission-critical applications, today announced it has received

a trial order for 50 propane-fueled DC generators from a major Tier 1 telecom operator in Southeast Asia. The generators will power off-grid

and bad-grid cell sites.

The

trial is the first phase of a potential five-year program that could cover approximately 2,500 of the customer’s sites. Discussions

between the Company and this customer have begun on the next phase of 200 propane generators. The customer has not committed to broader

deployment. If it proceeds, and based on current estimated system pricing, the opportunity could represent up to approximately $60 million

in revenue over five years. Polar’s DC Generator ranges from $19,000 to $27,000 each depending on accessories and service options.

The

order follows the Company’s more than five years of work with telecom operators in the Asia-Pacific region, including vendor qualification,

multiple rounds of technical evaluation, field testing, and operational reviews.

According

to the TowerXchange’s Q2 2024 Asia Guide there are 426,967 telecom towers/sites across the eight Southeast Asian markets.

“This

order is an important step toward modernizing telecom power with LPG and DC systems,” said Arthur D. Sams, Chief Executive Officer

of Polar. “We believe the combination of economic and environmental benefits will attract other operators and LPG distributors,

whose participation could help accelerate our sales. Our expectation is that orders from other Telecom companies in this region will

take months to close as opposed to years due to the large energy savings especially with the rising cost and theft of diesel fuel.”

Product

and expected benefits

Polar’s

DC generator combines its Supra™ system controls and a high-efficiency permanent magnet alternator with Toyota 1KS prime

power engines. Based on field experience, the Company estimates that:

●

Fuel:

The system uses approximately 40% less fuel than diesel AC generator solutions without solar. Paired with solar, savings have been

demonstrated at 59% and higher.

●

Maintenance:

The oil change interval is approximately 4,500 hours, versus approximately 250 hours for standard diesel AC gensets, which reduces

the cost of site visits.

●

Operating

cost: Because fuel is a large share of operating expense at off-grid and bad-grid sites, fuel savings has a meaningfully impact

on lowering total site OPEX.

Supply

readiness

Given

long engine lead times, Polar has purchased approximately 2,000 Toyota 1KS engines to support potential volume growth. The Company previously

wrote down approximately $4 million of usable engine inventory, and expects that using this inventory may support improved margins as

volumes ramp. Polar’s large inventory of Toyota 1KS engines should help facilitate a rapid delivery of generators into emerging

markets.

The

economics is driving the sale

Fuel

Savings. During the field trails Polar demonstrated 40% fuel savings. From field observation, diesel cost per site ranges from

$960 to $2,400 per month. The estimated diesel cost does not include theft in the region of 15% to 25%. The net savings at 40% is

$384 to $960 a month. Assuming a deployment of 2,500 sites, the annual saving ranges from $11M to $28M with Polar DC generators.

Maintenance

savings. Scheduled maintenance service for a Diesel AC generator is 200 to 250 hours; so, running 12 to 24 hours a day will require

18 to 36 service trips a year. The Polar DC generator with the Toyota engine has a scheduled service maintenance of 4,500 hours requiring

a maximum of 2 visits a year running 24 hours a year. The Company estimates that the cost is $100 to $150 per site visit for a Diesel

AC generator, totaling between $1,800 to $5,400 per year per site, while maintaining a Polar DC generator costs $600 per year running

24/7. Assuming a deployment of 2,500 sites, the annual saving ranges from $3M to $12M with Polar DC generator.

Broader

LPG opportunity

addition, a major local LPG distributor expects to receive a contract from its customer to fuel each site for 6 years. Our telecom customer

was concerned with getting propane to each site and the participation of a major LPG distributor was essential to the program success.

The LPG distributor will benefit with a substantial increase in revenues as new wave of opportunity opens with power generation using

LPG in place of diesel.
