The solar industry has evolved dramatically over the past few years. Today's installers, EPCs, and developers need more than simple layout tools—they need software that can design systems, analyze shading, forecast production, generate proposals, and manage projects efficiently.
Modern solar design software combines engineering precision with sales enablement, helping teams reduce design time, improve proposal accuracy, and close projects faster.
Whether you're searching for a HelioScope alternative, a PV*SOL alternative, or simply the best solar panel design software for your business, this guide compares the top platforms available in 2025.
Solar design software helps professionals model photovoltaic (PV) systems before installation. These platforms allow users to create system layouts, analyze shading, estimate energy production, and generate professional proposals.
Most modern platforms now include:
The best platforms combine these capabilities into a single workflow, reducing manual effort and improving project accuracy.
ARKA 360 is a comprehensive solar design and proposal platform that enables installers to design, sell, and manage solar projects from a single interface.
The platform combines 3D design, shading analysis, proposal generation, financial modeling, and permitting workflows, making it one of the most complete solutions for residential and commercial solar companies.
Residential and commercial solar installers looking for an end-to-end design and sales platform.
Aurora Solar has become one of the most recognized names in solar software thanks to its highly accurate remote design capabilities and premium customer experience.
Its LIDAR-powered modeling and advanced shading analysis allow installers to create accurate designs without requiring a site visit.
Residential solar companies prioritizing remote design and customer presentations.
SurgePV is a modern solar software ecosystem designed to support every phase of the solar project lifecycle—from design and engineering to proposal generation and financial analysis.
Rather than focusing on a single workflow, SurgePV connects sales, design, engineering, and project management into one platform, helping solar businesses reduce operational complexity and improve team collaboration.
Many solar companies struggle with disconnected software stacks that require multiple subscriptions and duplicate data entry. SurgePV addresses this challenge by bringing critical project workflows together, allowing teams to move from design to proposal to execution more efficiently.
Installers, EPCs, and developers looking for a unified platform that combines technical design with operational management.
HelioScope remains a favorite among commercial and industrial solar designers due to its powerful simulation engine and detailed electrical modeling capabilities.
The platform is particularly strong for performance forecasting and system optimization.
Commercial and industrial solar projects requiring detailed performance analysis.
PV*SOL is one of the most technically advanced solar simulation tools available and is widely used by engineers who require detailed performance modeling.
Engineers and consultants requiring advanced simulations.
You want a balanced solution for design, proposals, permitting, and sales workflows.
You prioritize remote design accuracy and premium customer presentations.
You want a unified platform that combines solar design, proposal generation, engineering workflows, and project management.
You focus primarily on commercial and industrial projects requiring advanced production modeling.
You need highly detailed engineering simulations and battery performance analysis.
The best solar design software depends on your business goals and project requirements.
For companies seeking a complete design-to-sales workflow, ARKA 360 and Aurora Solar remain strong choices. For organizations looking to streamline the entire solar project lifecycle, SurgePV offers one of the most comprehensive platforms available today. Meanwhile, HelioScope and PV*SOL continue to serve engineering-focused teams that require advanced simulation capabilities.
The right software can significantly improve design accuracy, proposal quality, project efficiency, and ultimately help your solar business scale faster.
