I'm considering buying a solar kit for a DIY installation. I'm planning to get help from some family members who are electricians and friends who have experience with this. However, I have some questions I hope you all can help with:
1. Is anyone from Kansas City? What has your experience been with the permitting process there?
2. Is it very different if you decide not to sell back energy versus selling back? I'm interested in net metering, but I'm mainly focusing on understanding the permitting and what I need for compliance with codes.
3. My roof is 15 years old, and I think it might be better to install ground mounts since there are fewer trees on my garage roof. Does anyone have affordable solutions for ground mounts? Has anyone successfully combined both ground and roof mounts?
I'm also looking at hybrid solar kits, like the ones from Sungold Power, and I'm eager to find out if there are better options within the same price range (around $10-11k) that would fit my usage of about 7kW of panels according to PV Watts.
What specific code compliance considerations do I need to be aware of? I understand I need a system shutoff, grounded metal equipment, and UL certified panels and inverters, but what else?
Lastly, what would the practical implications of using parallel versus series connections be? I might have some shading during the day in certain spots, especially in the morning and evening, and I want shading not to impact the whole system. From what I've read, I might need a parallel combiner box. Would the lower voltage of parallel connections create an issue since the panels will be about 50-75 feet away from the house's electrical system?

Also, if you want to make a career out of solar, keep in mind you'll need to be a licensed electrician. And yes, ground mounted systems typically have to be UL listed. If you're looking to build something that meets those standards, it's worth talking to a professional about the best materials and methods. Don’t skimp on safety!
For shading issues, parallel connections can actually handle it better than series connections, so you're on the right track with considering that. Make sure your combiner box is set up right to manage the shading. And yeah, I’d be cautious about voltage drop over long distances, but as long as you size your wires correctly, it shouldn’t be a huge issue. Just keep those considerations in mind!
Absolutely, sizing matters a lot for performance. Glad I could help!
Hey! I recommend checking out Solar Energy International; they have a free course on renewable energy that could help you out a lot! Regarding permits, they really do vary based on your local regulations, so make sure to do a bit of research on what’s required in Kansas City. Your roof’s age might be a concern, and you might get recommended to replace it before going solar. As for ground mounts, they can be pricey—just make sure to weigh your options and look into affordable alternatives! Good luck!
Thanks for the course link! I appreciate the help. Any tips on low-cost ground mounting options?
Yeah, I don't know much about KC either. I'm in a similar boat trying to find solid info. Those Sungold kits have mixed reviews, so it’s good you're doing your homework!
Thanks for the insight! I'll definitely look into wire sizing more closely.
