All About Solar PV Design Software

What is it?

Solar PV system design software is a helpful tool that helps design and execute residential and commercial solar construction plans. Although SAM technology (system asset management) is a newer device for solar PV installation, they are now an industry norm, if not a necessity, because they make the process of designing and installing solar panels easier and more efficient.

Many of these systems also incorporate other features that help with the installation process. For example, they can help determine installation price, energy production, and more. This allows you to maximize the efficiency and use of your PV solar panels.

Helpful For Both The Consumer And Installer

Solar PV design software is beneficial from both the consumer’s and the installer’s perspective. As the consumer, you will have a better idea of exactly how much energy you can create and save through your solar panels. This will allow you to better budget and know what to expect from your system.

From the installer’s perspective, PV software helps track business management, maximize solar PV system placement, and ensure to the customer that they are spending their money on the best installation and system possible.  

Factors To Consider

Since most PV solar software technology is backed by the National Renewable Energy Laboratory, you don’t so much need to consider be effectiveness or functionality of the software; you can assume that most software is efficient and helpful. Instead, you more so need to focus on specific capabilities that may be helpful for your individual needs.

Your Needs

When choosing a SAM technology, you need to know exactly what you need from it. Do you want the software to manage the sales proposal? Or do you just want it to aid the customer in terms of layout and expectations? Your needs are the top decision makers for which system to get.

If you do not know exactly what you need or are not the person in charge of the photovoltaic PV installation, then it will be difficult to select a software that is actually beneficial for your company and installations.

On the other hand, being in charge of the installation process or having a clear idea of your exact needs will help you select software based on its capabilities. All of the options on this review are great choices regardless of your needs because they’re grid-connected and will boost PV solar energy options


Know exactly how you want to use your SAM technology and integrate it into your PV design system. If you do not have a clear idea of how the system can or will integrate into your design process, you may waste a lot of money on something that does not function properly.

This is especially true if you work with a third party PV system. Make sure that the software you are selecting actually works with the third party system to ensure efficiency, functionality, and a good purchase.  

Cloud Storage Accessibility

Almost all of the SAM apps, including those associated with solar PVinstallation, are cloud based. This means that you will be able to access your software, solar power designs, and renewable energy options wherever you need it. Make sure that your company has access to a reliable and user-friendly cloud system so this does not cause you any problems in the future.

Although cloud accessibility is relatively easy today, make sure that you do your research before on cloud storage with your ideal software to save you time and trouble down the line.


With climate change getting progressively worse, it is important to transition to renewable energy. Solar power and solar energy are the best ways to fight climate change, resulting in the increased use of PV systems.

Solar PV design software is a necessity for solar installation. With the software, you’ll be able to effectively plan PV solar layout, show consumers that you are a professional installation company, and know the exact energy output of the installation.

Of the systems we looked at on this list, the is by far the best since it offers options beyond layout and design. With that being said, it is more expensive and may offer more features than you actually need.

To decide exactly which SAM technology to get for your company, simply assess and evaluate how you will integrate this system into your plan and what your exact needs are. If you are able to pinpoint those issues, you will easily be able to find a highly functional and efficient design system for your solar panel installation.
