Raigam Solar · Solar Panels
Engineered to Capture
Every Ray.
At the heart of every Raigam Solar system is a high-performance PV module — built to deliver more energy, for longer, in Sri Lanka's demanding tropical climate. Guaranteed to perform for 25 years.
Premium PV Modules
A Panel Is Only as Good as the Years It Keeps Working
That's why we install premium framed modules engineered for high efficiency, low degradation, and mechanical resilience — the same modules trusted in our megawatt-scale industrial projects, now available for every roof.
Panel Technologies
Not All Panels Are Equal
Here's the technology that makes the difference — the engineering behind every module we install.
Monocrystalline Cells
Made from single-crystal silicon, monocrystalline cells deliver the highest efficiency and the best performance in limited roof space — the ideal choice when you want maximum output per square metre.
PERC Technology
Passivated Emitter and Rear Cell design adds a reflective layer behind each cell, capturing light that ordinary panels waste — delivering more energy in low-light and early-morning conditions.
Half-Cut Cell Design
Each cell is split in two, reducing internal resistance and energy loss. Higher output, better heat tolerance, and stronger performance in partial shade — a real advantage on complex rooftops.
Framed & Frameless Options
Robust anodised-aluminium framing for standard installs, plus frameless modules for large-scale projects — a field where Raigam Solar has built the country's largest installations.

Technical Specifications
Panel at a Glance
Our flagship module — the Trina Solar Vertex 595W Mono PERC N-Type — sets the benchmark for efficiency and durability in Sri Lanka's climate.
Specifications apply to the Trina Solar Vertex 595W Mono PERC N-Type module measured under Standard Test Conditions (STC). Actual output may vary depending on installation angle, shading, and ambient temperature.
Why Raigam Panels
What Makes a Raigam Panel Different
High Efficiency
More power from every panel, every hour of daylight — optimised cell design maximises output per m².
Tropical-Ready
Built to withstand Sri Lanka's heat, humidity, and monsoon conditions without performance loss.
Low Degradation
Less than 1% output loss in year one, and only 0.4% per year after — guaranteed in writing.
Premium Build
Quality DC connectors and cables, framed for structural integrity on every install.
Built to Last
30 Years of Backed Performance
Every Raigam Solar panel is protected by two layers of manufacturer-backed international warranty — covering both build quality and long-term power output.
Product Warranty — Trina Solar
12 Years
Covers material and workmanship defects in the module, DC connectors, and cables — your assurance of build quality from day one.
Normal wear and tear excluded. REC Group panels carry a 25-year product warranty as a premium upgrade.
Linear Power Warranty — Trina Solar
30 Years
A guarantee of performance, not just parts. Trina Solar Vertex panels degrade no more than 1% in the first year, and no more than 0.4% per year after — maintaining at least 87.4% of rated output at year 30.
Measured under STC
To keep your performance guarantee valid, annual maintenance must be carried out exclusively by Raigam Solar Pvt. Ltd. Opting for REC Group panels as a premium upgrade extends the product warranty to 25 years with a matching 25-year power warranty.
