If you're a homeowner looking to design and permit your own system, you can use SolarDesignTool to help with your installation, however, please note that the app is primarily geared towards professional solar installers who are already familiar with the details of PV systems design. While we're happy to make it possible for homeowners to create their own permit packages we're not able to offer PV training, advice on how to build your system, or permitting guidance. We do not provide account managers and ongoing live support for homeowners and DIY users, please refer to our FAQ and Tutorial pages if you have any questions.
