Solar Advisory Services
Accelerating solar adoption through strategic advisory and technical excellence
OUR VISION
Why Choose us
We deliver end-to-end strategic support to accelerate solar deployment with technical rigour and financial clarity. We enable clients to navigate feasibility, design optimisation, regulatory compliance, and execution oversight with a data-driven, bankable approach. Our expertise ensures reliable project outcomes, mitigated risks, and long-term asset performance across diverse solar applications.
Feasibility Studies & DPRs
Our team conducts detailed site assessments, energy yield analysis, and techno-commercial feasibility to ensure every project is bankable and optimised.
Solar Design & Engineering
We deliver electrical, structural, and civil designs for rooftop, ground-mounted, and floating solar systems, aligned with IEC and CEA standards.
Owner’s Engineering & PMC
Acting as your technical representative, we oversee project execution, quality assurance, and commissioning — ensuring performance.
Tariff & Regulatory Advisory
We support developers, DISCOMs, and regulators in tariff benchmarking, power purchase agreements, and open-access policy development.
Performance Audits
Our performance audits identify technical bottlenecks, ensure efficient operation, and maximise solar generation throughout the asset life cycle.
Hybrid & Floating Solar
Combining hydro and solar expertise, we design floating and hybrid solar systems to enhance generation while optimising land and water use.
