A Real Step Forward in Clean Marine Mobility 

In 2024, a determined team from Goa set out to bring solar-electric boats to life, not just as a concept, but as a real, working solution for sustainable transport on water. Their intention was clear: to build a boat that wasn’t just electric, but thoughtfully designed, packed with features, and built with safety in mind. 

To make that happen, they needed a partner with the right experience and technical depth. That’s when they found Navalt—the team behind Aditya, India’s first solar ferry, and the company with the largest fleet of solar-electric boats in operation across the country. 

But this wasn’t just about sourcing a boat. The team wanted it to be built in Goa, using local capabilities, with Navalt stepping in as the technology and system provider. That’s how LRAJ GREEN was formed. And at the same time, Navalt launched Greenship, a dedicated brand to design and deliver an advanced solar-electric powertrain built for marine use. 

Now, that vision has taken shape on the waters of Panjim. Goa’s first fully operational solar-electric boat is live and performing as expected. This is especially significant because the state’s earlier attempt at launching a solar ferry didn’t succeed. That setback created a lot of doubt—but this new project has managed to turn things around and start a new chapter. 

A Launch That Made Headlines 

The vessel, named LRAJ GREEN, was officially inaugurated on July 17 at 6 PM by Dr. Pramod Sawant, Chief Minister of Goa, with Shripad Naik, Union Minister of State for Power and Renewable Energy, also in attendance. The event saw participation from local leaders, industry experts, and the media. 

The boat, which is certified by the Captain of Ports Department, will soon begin operating from the Panjim ferry ramp, offering cruise tourism services. It’s not just a launch—it’s a strong message that solar-electric boats are a viable reality. 

Built for Performance and Reliability 

The LRAJ GREEN runs on Greenship’s solar-electric powertrain, which was developed specifically for this vessel. The system was designed with performance, safety, and real-world conditions in mind. 

Here’s what powers it: 

Battery system:

Two 40 kWh RAY LFP marine-grade propulsion batteries, and a third 40 kWh auxiliary battery that supports air conditioning and other onboard electrical loads. In case of any failure in the main batteries, the auxiliary pack can seamlessly take over, offering redundancy and operational safety. 

Motors: 

Two 20 kW MAKO inboard motors built to S1 duty rating. These motors are engineered for extended use and long life, using a direct shaft drive for maximum efficiency. 

Solar panels: 

A 12 kW solar array supplies energy directly to the motors or charges the batteries, depending on available sunlight and load demand. The system smartly switches between sources to optimize energy use. 

Backup: 

A 20 kVA genset is onboard for emergency power supply, though it is expected to be rarely used. 

Control System: 

Everything is managed through a Vessel Control Unit (VCU), which balances energy flows and monitors system health. Remote monitoring and real-time dashboards allow both the onboard crew and technical teams to keep an eye on every key parameter—voltage, temperature, power output, and system alerts. 

Boat Specifications 

Why This Project Matters 

This boat is more than just a technical achievement. It reflects what’s possible when clean energy, local talent, and a clear vision come together. 

• It’s the first solar-electric boat in Goa that is fully operational 

• Goa becomes the ninth Indian state to adopt Navalt’s green propulsion technology 

• It’s also the first time a Navalt Greenship system powers a boat built by a third-party shipyard 

This collaboration with a Goan shipyard signals a meaningful shift, one where clean marine technologies are no longer limited to niche pilot projects. They’re ready for real-world use. 

Moving Toward Cleaner Waters 

This isn’t just a launch. It’s a reset. A sign that clean and quiet alternatives to diesel boats are possible and practical. It proves that solar-electric boats aren’t just experimental anymore, they’re here, and they’re working. 

And while there’s still a long way to go, projects like LRAJ GREEN show us that real change starts when people believe it’s possible and come together to make it happen.

Powering the Future of Marine Mobility

More such vessels can now be electrified with Greenship’s advanced electric propulsion systems. Greenship offers a unique combination of five energy sources—solar, wind, hydrogen, battery, and engine, customized to match the specific power and operational requirements of each vessel. Whether it’s a personal boat, cruise, passenger ferry, tug, barge, high-speed craft, or even large container ships and yachts, Greenship can deliver fully electric or hybrid solutions for low, medium, and high power-energy applications.

Greenship provides complete system design, propulsion packages, and integration/installation services tailored to each project. Battery systems can be customized up to 2 MWh capacity and 800V, available with or without IACS (DNV/IRS) class certifications.
