Top 9 Best Solar Power Software of 2026

Also Energy centers on energy yield simulation driven by configurable site and resource assumptions, with results structured for decision-making and engineering review. The workflow links solar site assessment inputs to downstream reporting outputs used during design and delivery. Automation reduces repeat manual rework for repeated roof or ground-mount configurations by reusing modeled assumptions and standardized calculations.

A tradeoff is that detailed electrical design artifacts like single-line diagram drafting and full BOM generation depend more on external design tools than on Also Energy alone. Best fit appears when an installation design process already has layout and electrical outputs, while energy modeling, loss reasoning, and performance expectations need stronger control and consistency.

Aurora Solar fits teams that design many residential and commercial projects and need repeatable layouts, proposal artifacts, and electrical design outputs that do not drift across revisions. The software workflow emphasizes guided design inputs, roof geometry and layout generation, shading and energy modeling, and bill-of-material style outputs that align with proposal packages. It is also used by sales and design teams that need faster iteration cycles when customers request changes to system size, module selection, or placement.

A tradeoff is that Aurora Solar depth can depend on how the team structures its design standards and component library, because unstructured revisions increase review time. Aurora Solar works best when a team runs design reviews using consistent assumptions and then exports deliverables into downstream processes like permit filing and utility interconnection packages. It is less ideal when a design team requires highly bespoke electrical engineering workflows that go beyond Aurora Solar’s standard export formats.

SolarEdge Designer centers on an end-to-end design workflow that starts with site and layout inputs and ends with exportable deliverables used on project closeout. Layout steps are guided toward common PV deliverable sets such as electrical single-line outputs and bill of materials that match SolarEdge component expectations. Design iteration is built around the SolarEdge product catalog so teams can keep string and inverter decisions aligned with what will be installed.

A tradeoff is that the workflow depth is strongest when SolarEdge inverters and power optimizers are the target hardware, and mixed-vendor projects often require extra manual checking. SolarEdge Designer fits projects where design teams need consistent outputs across multiple rooftops while maintaining fewer mismatches between design and commissioning. It is also a practical choice when handoff to monitoring and asset operations should follow the same equipment assumptions used during design.

OpenSolar is solar power software built for installers that need end-to-end proposal generation, design document output, and project tracking in one workflow. Its configuration focus centers on mounting and electrical system components used in real installer projects, with tools that produce customer-ready drawings and exportable deliverables.

The platform also supports production-style calculations used during sales handoff so drawings and bills of materials stay consistent across revisions. OpenSolar’s distinct value is how quickly a design workflow turns into a project deliverable tied to ongoing operations tasks rather than stopping at the drawing stage.

Solargis runs solar site assessment and PV system design workflows that connect geospatial irradiance modeling with plant configuration outputs for design handoff. Its process supports shading analysis and energy yield simulation to generate bankable-style deliverables like loss diagrams and production modeling inputs.

Solargis also supports operations workflows by tying production monitoring and asset performance management to ongoing performance checks. Integration paths emphasize exchanging design and model outputs with downstream engineering and monitoring systems.

Solar-Log is a solar power software stack focused on site monitoring and operational workflow for PV assets, not only design output. It centers on inverter telemetry and plant-level production tracking through Solar-Log devices and integrations that feed monitoring views and reporting.

Teams can use it to manage ongoing site performance, track alarms, and route corrective maintenance work tied to real generation behavior. For installers and designers, it fills the post-design loop where electrical design intent meets field data.

Sunnova Sunnova360 differentiates with portfolio-oriented solar operations tools that connect design data to ongoing production workflows. The core capabilities focus on asset tracking, site-level reporting, and operational task handling tied to specific PV installations.

Sunnova360 supports integration into monitoring and field workflows so installers and operators can move from build records into day-to-day performance oversight. The system is designed for governance across many sites rather than standalone one-off design export.

PVcase is a solar power design and sales workflow tool that turns a site input into a reviewable design package. Its core strengths center on rooftop and ground-mount PV system design generation, automated drawings and outputs for proposal use, and configuration workflows that reduce rework between design, BOM, and customer-facing materials.

PVcase also supports energy yield and performance-oriented outputs used during solar site assessment, including shading and loss-oriented reasoning represented in its design artifacts. The product focuses on installer and designer throughput rather than deep engineering-level electrical engineering control compared with tools that expose more low-level electrical and interconnection modeling steps.

Scanifly generates solar project documents from structured inputs, with an emphasis on workflow for installers and designers. The core work centers on PV system design deliverables such as rooftop layout outputs and electrical package artifacts that can be prepared for downstream sharing.

Scanifly also supports irradiance and performance modeling workflows used to estimate energy yield for proposed systems. Administrative control and integrations depend on how design work is managed across a team and what export formats are used for handoff into other tools.
