This allows the user to quickly draw the roof outline, define obstacles, and place solar panels efficiently. The ability to adjust panel tilt and azimuth is also vital for optimising energy production.

2. Accurate Shading Analysis & Solar Simulation

Shading analysis is paramount in Australia, where trees, neighbouring buildings, or even chimneys can significantly impact a solar array's performance. A good solar simulation software should offer detailed near field shading calculations, allowing you to identify shaded areas throughout the day and year. This data is critical for accurate energy simulation and ensuring your pv systems deliver expected yields.

3. Energy Production Estimates

What's the point of a design if you don't know how much power it will generate? Effective solar panel design software free options will provide estimated annual and monthly energy production figures. These calculations should consider local weather data, panel efficiency, inverter losses, and the results of the shading analysis. This helps you provide realistic expectations to your customers and craft compelling proposals.

4. System Components & Electrical Design

The best tools allow you to specify different system components – various solar panel models, inverters (string, micro-inverters, optimisers), and even solar battery storage options. Some advanced design software might even offer basic electrical design functionalities, helping you to plan wiring and connections.

5. Financial Analysis (Even Basic) & Sales Proposals

While comprehensive financial analysis might be reserved for paid platforms, some free solar design software offers basic payback period calculations or estimated savings. The ability to generate simple, professional sales proposals directly from your design is a huge plus, streamlining the sales process for your solar business.
