What we install
Solar built for island properties.
Off-grid and battery storage first, because on this island the question is not only what the system saves you, it is whether the lights stay on.
Solar for Villas, Guesthouses and Eco Resorts
Purpose-built systems for Tobago's vacation rentals, eco retreats and tourism properties.

Scalable arrays for hotels, restaurants, warehouses, shops, offices and factories across Trinidad.
EV Charging and Solar Car Parks
Charge an electric vehicle free from your own roof, or shade your car park with panels.
Smart Monitoring and After-Sales Support
Watch your system from your phone, with full warranty cover and tech support behind it.
Energy Efficiency Audits and LED Upgrades
Cut the load before you size the array, with an efficiency audit and LED upgrades.
Building Integrated Photovoltaics
Panels built into the structure itself, for designs where a bolt-on array will not do.
How the system fits together
Follow the power from the roof to the kettle.
Tap any part of the system to see what it does, then switch between sun, after dark and a grid outage to see where the power is actually coming from.
Solar panels
Tier 1 panels, bolted to rails anchored through the roof and sealed. They carry a 12 to 30 year product warranty and are guaranteed to still make at least 85 percent of their rated power after 25 years.
Canadian Solar, Jinko, JA Solar, Q-Cells, REC, Silfab, Trina, Longi
Power optimisers
One per panel. Each panel is managed on its own, so a shaded or dirty panel drags down only itself instead of the whole string. On a Tobago roof with palms and afternoon cloud, that is not a luxury.
Also available as micro inverters
Hybrid inverter
The brain. It turns DC from the roof into the AC your property runs on, decides moment to moment whether to feed the house, charge the battery or send the surplus out, and switches you over when the grid drops.
SMA, Fronius, Enphase, APsystems, Solis, Sol-Ark
Battery storage
Where the afternoon goes so you can spend it at night. This is the part that decides your ride-out time, and it is the reason a property can carry on through an outage instead of waiting on the grid.
FranklinWH, Sol-Ark hybrid, Tesla Powerwall, APstorage
Your loads
Lights, fans, fridges, freezers, the water pump, the internet and the air conditioning. We measure what you actually run before sizing anything, because the load list sets the array and the battery, not the other way round.
Ask about an efficiency audit and LED upgrade first
Zero-export meter
Required for grid-tied systems in Trinidad and Tobago, and its whole job is to stop your system pushing power back onto the T&TEC network. That is why the diagram shows nothing leaving on a sunny day: surplus goes into the battery, and when the battery is full the inverter throttles back instead of exporting.
Supplied and configured as part of the install
The T&TEC grid
Still connected, still there as a backstop on a grid-tied system. The difference is that it stops being the thing your property depends on and becomes the thing your property falls back on.
Off-grid designs leave it out entirely
Monitoring on your phone
Production, consumption and battery state of charge, live, from anywhere. For a villa owner who is off-island for months at a time, this is how you know the property is fine without calling anyone.
Included, with warranty cover and tech support behind it
Sunny: the roof runs the property and charges the battery. Nothing goes back out to T&TEC, because that is exactly what the zero-export meter is there to prevent. Once the battery is full, the inverter simply makes less.
After dark: the battery runs the property. The grid only makes up the difference if the battery gets low.
Grid outage: the inverter disconnects from T&TEC and your property keeps running on the battery, and on the roof again in the morning. This is the part your neighbours do not have.
Tap any box in the diagram to read what it does.

The Ride-Out Planner
How long do you stay up when the grid goes down?
Pick your property, then compare a standard system against one built to carry the extras. Nothing here is about the bill. It is about time.
