Lesson(s) in which students create and (mostly) finalize a plan for their system, incorporating work done in battery charging, panel building, and inverter lessons, as well as thinking about site and mounting specifics.
Brianna's Quick Notes: N-DEPTH SYSTEM DESIGN So far, we've looked at everything individually but really, it's all connected What are the parts? How do they connect? OK, DESIGN PROCESS what are the specifications we need: - this might be cost, functionality, security, size, locatability, etc. - Size each piece of the system: panels must be able to generate enough power batteries must be able to store enough inverter must be able to handle enough whole thing must cost little enough What else do we need to consider: site
what are the options for these evaluate how they are on all the different fronts
At the moment I am not sure of what the structure of this lesson should be. Maybe start each category with some constructed questions (how much power is lost with this size cable?) Then ask students what they could do to change that, then have them figure out what their project requires. Any ideas of how to make this more creative would be appreciated.

Discussion
Seems like, as you say, this should be a lot of connecting stuff? Like - okay, we know we need this much power, of this type, at this time of day…what does that mean for batteries? What about inverters (do we need one?) Etc etc.
Maybe you could just brainstorm all the things we need to think about and then if there's any ones that seem to need a lot of explanation at this stage, put them as a previous lesson? (for example: fuses and grounding. Could this be introduced in a “basic wiring and electronics” lesson? or is it something to mention now and go into in depth afterwards?
