The SD Nexus Platform
SD Nexus is an integrated software platform guiding renewable energy projects from initial site selection to final investment analysis. Our interconnected modules streamline technical modeling and financial forecasting for PV-BESS hybrid systems, ensuring bankable accuracy at every stage.
A Fully Integrated Decision Engine
Eliminate data silos and streamline your project lifecycle with a single source of truth.
Integrated Workflow
Outputs from one module seamlessly become inputs for the next, ensuring data consistency.
Bankable Accuracy
Leverages industry-standard data sources like NREL and applies granular loss modeling.
Investor-Ready Reports
Generates comprehensive financial metrics (NPV, IRR, ROI) to support decision-making.

Platform Modules
A Suite of Interconnected Tools
App 1: GHI Calculation
Purpose: Estimate site-specific solar irradiance to inform system sizing and location suitability.
- Pulls multi-year hourly solar data using the NREL API.
- Accounts for soiling, shading, and degradation effects.
- Outputs serve as the energy foundation for system modeling.
App 2: System Design
Purpose: Generate PV and BESS design specifications tailored to capacity and land constraints.
- Users input specs like DC/AC ratio and POI limits.
- Outputs include number of panels, inverters, and land area.
- Feeds directly into CapEx/OpEx and financial tools.
App 3: CapEx & OpEx
Purpose: Estimate capital and operational expenditures for multiple configurations.
- Computes granular CapEx for all major components.
- Annual OpEx varies by system type and location.
- Outputs are normalized for LCOE/LCOS and ROI metrics.
App 4: Energy Modeling
Purpose: Simulate hourly and yearly energy output for all supported configurations.
- Covers AC-coupled, hybrid PV+BESS, and advanced systems.
- Applies system losses at DC, inverter, and MV levels.
- Includes clipped energy tracking and loss auditing.
App 5: Financial Modeling
Purpose: Estimate revenue and calculate financial viability over project life.
- Calculates PV and BESS revenue using LMP inputs.
- Supports grid/PV charging and advanced dispatch logic.
- Outputs include NPV, IRR, ROI, and payback period.
App 6: System Comparison
Purpose: Visualize and compare financial and technical metrics across designs.
- Produces bar charts, cash flows, and investor plots.
- Normalizes metrics per MW and system size.
- Highlights performance gains over an AC baseline.
