250kW Off-Grid Three-Phase Solar System for a Private Island Resort in Panama

Customer Background

Our client operates a 5-star resort with 20 rooms on a private island in Panama, dedicated to delivering a luxurious experience to their guests. As part of their energy plan, they sought to implement a green energy solution to reduce dependence on traditional power sources.

Project Requirements

The client required an off-grid solar power system with the following features:
1.Automatically activate the generator when the battery drops to 20%.
2.Switch back to battery power when the charge reaches 80%, and use solar power when available while simultaneously charging the batteries.
3.Fully automated energy management to maximize efficiency.
4.A comprehensive solution that includes installation and commissioning, as it is challenging to find solar equipment locally in Panama.

Our Solution

We provided a customized off-grid solar power system equipped with an EMS (Energy Management System) to intelligently manage energy distribution between solar panels, batteries, and the generator. Our technical team ensured that the system could seamlessly meet the client’s high standards for automation.

Additional support included:

*Dispatching a fluent English-speaking professional engineer to Panama for installation and commissioning.
*Training the resort’s electricians to operate and maintain the solar power system for long-term reliability.
*5 years free online maintenance. Our engineers regularly  check the power generation data of solar panels, the charge and discharge data of lithium batteries, and the output data of inverters.

Project Outcomes

After finalizing the order through video meetings, we successfully completed the design, production, and delivery of the system. The client appreciated our comprehensive solution, which enabled them to confidently deploy this advanced energy system. After 8 months, the entire solar system paid for itself, saving the customer the cost of diesel.

Customer Feedback

“The Tanfon team was incredibly professional. The entire process, from system design to installation, was seamless. Their engineer not only ensured smooth installation but also trained our team thoroughly. Now our resort is energy independent and provides an authentic eco-friendly experience for our guests.”
