1 MW Rooftop Installation in Guyana

When a major distribution center on the outskirts of Georgetown needed to cut its skyrocketing energy costs, they came to Amosolar Co; Ltd with a clear goal: maximize generation within a limited rooftop area. The solution was a 1 MW rooftop installation, built entirely with 650W solar panels—some of the most powerful modules available for commercial rooftop applications today.

The site itself is hard to miss. The warehouse features a series of distinctive red metal roofs, which turned out to be ideal for a non‑penetrating ballasted mounting system. Over the course of six weeks, our installation team covered more than 4,500 square meters of roof surface with 650W high‑efficiency bifacial modules. Despite the high output per panel, the total system footprint was kept compact, leaving plenty of roof space for future expansion.

Why 650W Panels for This Project?

The client originally considered a 500W panel solution, which would have required nearly 30% more roof space to reach the same 1 MW capacity. By switching to our 650W solar panels, we reduced the number of modules needed from over 2,000 to just over 1,500. Fewer modules meant less racking material, fewer labor hours, and a cleaner installation—all while achieving the same target output.

For a business operating in Guyana’s hot coastal climate, panel efficiency also matters for long‑term reliability. These modules are rated for high‑temperature environments, with a low temperature coefficient that keeps them producing well even on the hottest afternoons.

Installation and Grid Connection

Because the facility runs 24/7, the installation was phased to avoid disrupting operations. We started on the southern roof section, which had the least impact on loading docks and warehouse traffic, then moved to the northern sections as the project progressed. The system is connected through a grid‑tied inverter setup, allowing the client to offset daytime consumption and export surplus during weekends when the facility runs at reduced capacity.

According to the facility manager, the first month after commissioning showed a 38% reduction in electricity bills, even with the grid still providing backup power. Over the next year, the system is expected to generate roughly 1.4 GWh of clean energy, cutting carbon emissions by an estimated 550 metric tons annually.

A Few Words from the Client

“We had looked at solar before but always felt the technology wasn’t quite there for our rooftop layout,” the facility manager told us. “The 650W panels changed that calculation. We got a full megawatt without using every square inch of roof space. Amosolar handled the engineering, the permitting with GPL, and the installation without any major hiccups.”
