Engineering services backed by a public solar data reference covering Guinea, and by the tools that read it. Every deliverable cites its sources.
No recycled global averages: Guinean communes are curated series by series, NASA POWER cross-checked against SARAH-3 and CAMS. Uncertainty is quantified locality by locality and the A/B/C doctrine documented variable by variable.
Kuma Solar Bridge and the public API read the catalog directly: no irradiance retyping between projects, and every displayed value traces back to the reference dataset.
Kuma engineers co-authored two peer-reviewed papers (Energies 2025, Energy Reports 2025) on decarbonizing off-grid communities. The method is public, with stated assumptions and referenced formulas.
· WHAT WE DO
Access to our data: some twenty locally calibrated energy and climate variables, traced and versioned.
Discover the API →A sizing tool, a dashboard or a calculator that reads the catalog directly, with no irradiance retyping from one project to the next. Kuma Solar Bridge is the public demonstration. Deliverable: a deployed, documented tool powered by the API.
Scope a tool →Energy yield, LCOE and IRR computed on the site's own data: 34 Guinean communes covered, with documented P50/P90 and uncertainty. Assumptions listed, formulas referenced. Deliverable: a costed report ready for decision or financing.
Request a scoping →Received an installation quote? Independent verification of the sizing and the promised yield against your commune's actual data. No commercial ties to any equipment vendor. Deliverable: a written 2-4 page opinion with quantified points of attention.
Have a quote checked →Studies and annexes meeting the requirements of international funders (AFD, AfDB, World Bank, GIZ), backed by a public, versioned, citable reference dataset that evaluators can verify themselves. Deliverable: a complete technical file with sourced data.
Build a file →A hands-on workshop for engineers, technicians and universities: reading the catalog, understanding P50/P90 and uncertainty, producing first analyses in the site's Python workbench, nothing to install. Deliverable: a one-day session, materials and datasets included.
Organize a session →Thirty minutes by video, no commitment, to understand the need and say honestly whether the assignment is one for Kuma.
Scope, deliverable, timeline and price, sent within two working days. No assignment starts without an accepted scoping.
Short check-ins and access to the data being used, throughout the assignment.
Every figure is backed by a dated, citable release of the public reference dataset: your funders can verify it themselves, years later.
