CCISM round table: Nexus Carib invited to speak on energy and building management

On July 16, the Chambre Consulaire Interprofessionnelle de Saint-Martin gathered three local energy players at its premises around a single question: what concrete solutions for businesses in the territory?

#NiceCarib was among the invited speakers, alongside Watt Sun SXM and Helios, to represent the automation and building management side.

 

A round table born of a simple observation

In Saint-Martin, electricity is still overwhelmingly carbon-based, and its cost weighs directly on business competitiveness. That’s no secret to any business leader on the island.

As part of its support program for businesses in their energy and environmental transition, the CCISM wanted to give professionals concrete reference points rather than general principles. Where to start. Which solutions actually exist in the territory. At what cost. With what measurable benefits.

The format was deliberately direct: three speakers, ninety minutes of discussion, then open networking time with the audience.

 

Producing and managing: two trades, one equation

The speakers’ complementarity was no coincidence.

Watt Sun SXM and Helios covered the production side — photovoltaics, solar solutions adapted to local constraints. #NiceCarib brought the management side — automation of shutters, lighting, air conditioning and access, plus real-time consumption metering.

It was precisely the connection between these two worlds that fueled the most interesting exchanges of the evening.

Producing your own electricity is an excellent investment at our latitude. But a solar installation doesn’t decide when your water heater kicks in, or whether your air conditioning runs in empty offices at the weekend. This gap between production hours and consumption hours remains the blind spot of many installations.

Managing your building is what allows the energy you produce to actually be used — and the energy you buy to stop being wasted.

 

The questions that kept coming back

The exchanges with the audience confirmed that the barriers to investment are clearly identified by local businesses — and that they are legitimate.

The entry cost. The budget question came up quickly, and that’s only natural. The answer lies less in a single figure than in a step-by-step logic: start with the most impactful items, measure, then expand.

Hurricane constraints. A specifically local concern that no one in Saint-Martin can wave away. It shapes equipment choices just as much as the budget.

Return on investment and financing. How long to pay it back. Which schemes can be tapped. This is arguably the topic on which businesses need the most support — and one of the roles the CCISM usefully plays through this program.

 

What we take away from it

The caliber of the questions confirmed something we’ve been observing for several months: businesses in Saint-Martin no longer wonder whether the energy transition concerns them. They are looking for applicable, quantified solutions adapted to their reality.

That’s a notable shift. And it’s precisely the ground on which #NiceCarib wants to be useful.

Thanks to the CCISM’s Engineering Unit for the organization and the quality of the setting. Thanks also to Watt Sun SXM and Helios for exchanges that showed these solutions are best designed together rather than in isolation.

You produce by day. You consume in the evening. That’s where it gets stuck.

You’ve taken the leap. Panels installed, inverter in place, production starting at sunrise.

And then you look at your numbers. Your production is great. Your habits, on the other hand, haven’t budged an inch.

This isn’t an anomaly. It’s the blind spot of most residential photovoltaic installations: solar takes care of producing. Nobody takes care of consuming at the right time.

 

The gap no one explained to you

Your solar production follows a simple curve. It starts around 7 a.m., peaks between 11 a.m. and 3 p.m., and collapses in the late afternoon.

Your consumption, on the other hand, follows exactly the opposite pattern. Low during the day when the house is empty. It explodes between 6 p.m. and 10 p.m. — air conditioning on full blast, lights everywhere, the water heater kicking back in, the kitchen in full swing.

The result is almost absurd: you produce massively at the very hours you consume least, and you consume massively at the hours you no longer produce.

All the energy you produce during the day but don’t use goes back to the grid — often sold at a rate well below what you’ll pay to buy it back in the evening. And every kilowatt-hour consumed after sunset is purchased at full price.

In the Caribbean, where electricity rates are structurally high, this gap weighs heavily on your real profitability.

 

What home automation changes in the equation

The principle is simple: instead of letting your home consume at the whim of your habits, you shift whatever can be shifted into your production hours.

This is what’s called managed self-consumption. And it’s exactly the role of the Nice Yubii ecosystem.

The water heater, moved into full sunlight
This is the most immediate lever. A water heater accounts for a significant share of your consumption, and it doesn’t care one bit what time it heats — as long as the water is hot when you need it. Scheduled to run between 11 a.m. and 3 p.m., it operates almost for free on your own production.

Air conditioning, pre-cooled before you get home
Instead of starting at full power at 6 p.m., when you’re no longer producing, your system can lower the temperature in the late afternoon while the sun is still shining. The house is cool when you arrive, and the air conditioning only has to maintain — not catch up.

Solar shading that lightens the load
Motorized shutters and blinds driven by sunlight directly reduce incoming heat. Less heat, less work for the air conditioning, fewer kilowatt-hours to cover. Your solar production then covers a far greater share of your real needs.

Heavy consumers, triggered at the right time
Washing machine, pool pump, filtration — anything that can run on a delayed schedule can be programmed into your production hours instead of your purchase hours.

 

See, so you can act

None of this works well in the dark.

That’s where connected metering modules come in. By seeing in real time what your installation produces and what each appliance consumes, you stop managing by feel.

You see the gap. You see which appliance really weighs on the bill. You see the immediate effect of every adjustment. And you can fine-tune your automations month after month, based on the seasons and your actual usage.

A solar installation without consumption monitoring is a dashboard with no speedometer. It moves forward — but you don’t know how fast.

 

Solar and home automation are not competitors

That’s the message we’d like to make clear.

Photovoltaics are an excellent investment in the Caribbean. Our sunshine is one of the greatest natural assets of our islands, and it would be absurd not to harness it.

But producing energy and using it well are two different trades. Solar answers the first question. Home automation answers the second.

Together, they form a coherent system: a home that produces intelligently and consumes at the times when it costs the least.

Apart, each leaves part of its potential untapped.

 

If you’re already equipped with solar

Good news: you don’t have to redo anything.

The Nice Yubii ecosystem adds on to your existing installation. It doesn’t replace your panels, your inverter or your production system. It manages what happens after the meter — in other words, everything your photovoltaic installer couldn’t handle.

A certified [ART]IST can analyze your production and consumption profile, then identify the automations that will have the most impact on your self-consumption.

You invested in production. Now invest in how it’s used.
