The Lumen Grade

We evaluate software using an authoritative, transparent algorithm. No generic marketing fluff—just the technical "Why" behind the score.

1. The Three Pillars

Every tool is audited against three core technical vectors. These inputs form the baseline of the Lumen Grade.

Operational Depth

We evaluate the tool's ability to solve complex, solar-specific problems rather than generic workflows. We look for technical substance: LIDAR accuracy, bankable production modeling, VPP telemetry, and utility-grade structural engineering.

Scalability

We assess the infrastructure's capacity for enterprise volume. This involves auditing API maturity, bidirectional endpoints, multi-team workflow automation, and the openness of the platform's architecture.

Industry Consensus

A normalized meta-score derived from high-volume user data (G2, Capterra) to ensure market validation. We verify that a tool's technical excellence actually translates to ease-of-use and reliability in the field.

2. The Lens Pivot Logic

Not all software should be judged by the same rubric. We re-weight our three pillars based on the "DNA" of the tool—what we call its Lens.

Specialist Lens

Evaluates Deep Tech innovators building highly technical, single-pillar solutions.

50% Depth 25% Scale 25% Consensus

Strategic Core

Evaluates the foundational operating systems and connective tissue of a solar business.

45% Scale 30% Depth 25% Consensus

Utility Lens

Evaluates point solutions designed for speed, low-friction adoption, and immediate ROI.

3. Math in Action

Absolute traceability. See exactly how a typical score is calculated.

Example: Calculating a Specialist Tool

For a Deep Tech design tool scoring an 8.5 in Depth, 7.0 in Scale, and 9.0 in Consensus:

(0.50 × 8.5) + (0.25 × 7.0) + (0.25 × 9.0) = 8.25

Depth Contribution: 4.25 Scale Contribution: 1.75 Consensus Contribution: 2.25

Final Lumen Grade Value: 8.25

4. Performance Tiers

Absolute classification. We map technical authority to three clinical tiers to simplify high-stakes decision making.

Elite Tier

Grade: 8.5 – 10.0

Institutional leaders distinguished by deep technical moats, NREL-validated physics engines, and enterprise-grade API maturity.

High Perf

Grade: 7.6 – 8.4

Advanced systems designed for scaling SMBs. Characterized by stable interoperability, field-proven reliability, and high structural consensus.

Standard

Grade: ≤ 7.5

Foundational tools focused on speed, rapid adoption, and low-friction operational entry for emerging solar teams.
