# Best Solar Design Software - Page 3

  *By [Daniel Rivera](https://research.g2.com/insights/author/daniel-rivera)*

   Solar design software, also known as photovoltaic (PV) design software, is a design tool used to design, simulate, and analyze the performance of solar power systems. It is used by solar development, engineering, and consulting firms to design layouts, modify designs, and calculate materials and installation costs.

Solar design software assists users in creating simulations of different solar power system components, including solar PV modules, inverters, battery banks, cables and accessories, etc. These simulations are used for estimating the amount of power that will be consumed or produced subject to different atmospheric conditions. It assists in financial modeling and analysis to examine cost savings over a given time period and helps create sales proposals. It also offers a dashboard for users to view projects and manage requirements.

To qualify for inclusion in the Solar Design category, a product must:

- Create designs of photovoltaic or solar energy systems
- Allow users to modify the designs, such as adjustment of the placement of the components in the layout.
- Offer 3D modeling capabilities to view proposed solar panel layouts from various angles
- Offer automation capabilities to automate layout creation and workflows
- Generate 3D simulations of photovoltaic installations and conduct shading analysis to analyze shading caused by nearby objects
