I'm considering solar power for my home, but I'm torn between going for a DIY approach or hiring a professional. I have zero experience with solar setups or electrical work, and my energy use is around 70kW a day—yes, I know that's high, but it's accurate from my power bill. I'm looking to offset a portion of this usage, maybe around 8-10kW.
I'm thinking about getting quotes for a system installation, which I estimate will cost about $30-40k. However, I'm tempted to try a DIY route since I wouldn't need battery storage, as I plan to have it grid-tied to use all the power produced immediately. I've heard mixed opinions about this approach, with some saying solar without storage is a no-go. Also, I'm planning to mount the panels on a standalone awning as my roof was just replaced last year, and I live in an area with storms in Texas. I'd really appreciate any advice, especially regarding the Tesla Powerwall or alternatives!

If you're new to solar, I'd definitely recommend against starting with a grid-tied system yourself. It’s really important to prioritize safety, both financially and physically, so hiring a qualified contractor might be the best route. If you're purely looking to offset costs, a pro can help ensure everything is done correctly. But if you're keen to learn about solar, starting small with a DIY project like a simple standalone system could be a fun way to dive in without risking too much money. Just steer clear of the solar rental or lease agreements—they can be a trap!
I started out by installing 4 x 400W solar panels directly connected to a mini split system last year—great way to learn! It now offsets about 25% of my heating/cooling usage. I’m also adding a limited battery system for nighttime use. Small projects like this are a great way to get hands-on experience and build your skills before diving into a bigger system.
Was it really hard? What kind of issues did you face?
Not too many major issues, just some minor ones. My roof wasn't suitable, so I built a patio cover for mounting. I crafted my brackets from aluminum, figured out cable running techniques, and learned about solar cutoff switches. I even discovered MC4 connectors and how to splice them correctly. It was super rewarding to finally get it all working! Remember, my setup isn't grid-tied, which made things simpler too. This forum was super helpful for advice when I got stuck.
Awesome! Any YouTubers you recommend for learning more?
Good point! If I do go DIY, I'll definitely hire a certified electrician for the grid hookup.
