Advisory for every decision stage
Solar programs fail when early assumptions are weak, procurement is poorly structured, implementation is not independently verified, or performance is not monitored after commissioning. Radiance Advisory supports institutions across the full decision cycle, from feasibility to long-term performance.
From field reality to investment decisions.
Field Reality
Access constraints, unreliable grids, fuel dependence, fragile infrastructure, site-level variation, maintenance gaps, and operating risks.
Technical Assessment
Load profiles, system sizing, battery autonomy, equipment specifications, lifecycle cost, implementation assumptions, and risk registers.
Decision Output
Feasibility reports, investment cases, tender packages, due diligence notes, M&E frameworks, implementation roadmaps, and scale-up strategies.
The work behind the recommendations.
Every decision note we produce is built on disciplined modeling: diurnal load curves matched against PV generation, daily energy balances, and explicit risk registers. The visuals below are representative outputs from recent feasibility and due-diligence engagements.
- 01
Feasibility Studies
We assess whether proposed solar projects are technically, financially, operationally, and socially viable. Studies are designed to support investment decisions, donor funding, procurement preparation, and program planning.
- 02
Technical Due Diligence
We review solar projects, portfolios, vendors, designs, budgets, and implementation assumptions to identify risks before funds are committed or contracts are signed.
- 03
Procurement and Tender Support
We help institutions structure solar procurement processes that are clear, competitive, technically sound, and appropriate for Sudan's field conditions.
- 04
Owner's Engineer and Technical Advisory
We represent the client's technical interests during implementation, helping ensure that solar projects are delivered according to design, quality standards, and contractual requirements.
- 05
Monitoring and Evaluation
We design and implement monitoring systems that help institutions understand whether solar projects are working, being maintained, and producing the intended public-service or humanitarian value.
- 06
Program Design
We help institutions design solar programs that can be funded, implemented, monitored, and scaled. This includes technical design, delivery models, stakeholder alignment, geographic prioritization, and implementation planning.
