Thumba Solar Agriculture Pumpsets

Thumba solar pumpsets are built on two deep areas of expertise: submersible motor design (our core business since 2003) and solar power system engineering. Because we design both the motor and the solar system in-house, both are optimised together — delivering more than 27% solar efficiency and 55% pumping efficiency, significantly above standard off-the-shelf solar pumps. Our stainless steel fabricated pumpsets are also built for long-term agricultural field conditions, not just for spec-sheet performance.

It depends on your location's sunlight pattern and your priorities. Mono Crystalline panels work well in low-light or partially shaded areas. Polycrystalline panels suit areas with consistent strong sunlight. CIGS Thin panels offer exceptional lifespan — our 2014 installations are still running in 2026. Bifacial panels (2026 current standard) give 25%+ efficiency by generating from both front and back surfaces, and need 40% less space than older panel types. Our team will recommend the right option after assessing your site.

CIGS stands for Copper Indium Gallium Selenide — rare metals used as semiconductor materials in thin-film solar panels. This semiconductor composition gives CIGS panels exceptional longevity: the systems we installed in 2014 are still fully operational 13 years later. Their thin-film construction also makes them more resilient to microcracks caused by temperature cycling in outdoor agricultural environments.

We supply solar pumpsets from 1HP to 100HP, handling depths from 30 feet to 1600 feet — covering shallow open wells through to very deep borewells. All pumpsets use stainless steel fabricated submersibles. The right HP and stage configuration is determined by your well depth, required discharge volume, and the crop or use case. Our team does a free assessment before recommending.

Yes — that is one of the main advantages. A solar pumpset runs entirely on energy from the solar panels, with no grid electricity required. This makes it ideal for farms in remote locations, areas with unreliable grid supply, or farmers who want to eliminate recurring electricity costs for irrigation. For 24-hour water availability, a battery bank can be added to store surplus daytime solar energy for use at night.
