Las Vegas, 12-14 September 2023. RE+ is North America's largest renewable energy show, and the buyers who stopped at our booth were not browsing. They arrived with project schedules and a compliance checklist.

What US Buyers Asked First

1. Which standards apply to the complete fixture? Not just the LED driver, but the housing, wiring and battery enclosure. Buyers wanted the certificate scope to match the product they would install.
2. Is the lithium battery safe under abuse? They asked about cell chemistry, BMS protection and what happens in a short-circuit or overcharge event.
3. How does the lamp perform in cold winters? Northern states need a charging profile that protects the battery below freezing, not a generic operating range.
4. What does after-sales look like from 12 time zones away? Spare parts, response time and who pays freight on a warranty claim.
5. Can the fixture be serviced without replacing the whole head? Maintainability is part of total cost of ownership, and US contractors calculate it.

Products on Display

We showed integrated solar street lights, split solar street lamps, solar garden lights and solar camera lights. The camera-integrated units drew interest from buyers working on commercial sites and residential communities where lighting and security are budgeted together.

Visitors tested real brightness, motion-sensor modes, dusk-to-dawn settings and adjustable panel brackets. The questions that followed were about aluminium housing quality, heat dissipation and harsh-weather adaptability — cold winters, strong sun and heavy rain in the same project portfolio.

Cold Weather, Specifically

The cold-weather question deserves its own note. Lithium cells charge slowly below freezing, and a charge controller that ignores temperature will either refuse to charge or, worse, damage the pack. We explained the low-temperature cut-off and the charging window our BMS allows, then offered a test report from a northern installation.

The buyer's response was practical: he wanted the same report in a format his electrical inspector would accept. That is the level of detail US projects demand, and it is easier to provide before the order than after.

Beyond the US

We also took inquiries from Latin America, Europe and Oceania, which suggests the same five questions are becoming global. Compliance is no longer a regional hurdle; it is the entry ticket to serious projects.

Follow-up conversations are now focused on two municipal trials and one commercial campus where lighting and camera coverage will be specified together.
