I'm planning to install a solar system on my house, specifically on the southern-facing roof area which is about 48' x 14'. My energy usage peaks at about 40kWh on average days. I want to ensure I have battery backup while also being able to connect to the grid. Although I can find decent solar panels, I'm unsure about all the other components I need for a complete setup, including things like mounting brackets. Any recommendations or advice would be greatly appreciated!

I've personally used Renewable Outdoors and Portable Sun, both were great with quick shipping! What stood out to me was that they offered free shipping and no sales tax since they’re based out of state. Definitely worth checking out!
I’d suggest checking out Signature Solar or Current Connected for your system. From my research, I’ve seen a lot of positive feedback about Current Connected, but hear that Signature Solar has had some customer service issues recently. I learned a lot by watching YouTube channels like "DIY Solar with Will Prowse". Eventually, I bought from Signature because they had a good deal with free shipping at the time.
For sizing your system and understanding what parts you'll need, definitely watch tutorials from channels like 'Project with Everyday Dave.' Also, the NREL has a tool called PVWatts that can help you estimate your solar energy production based on your location. Here’s a snapshot of my parts list for reference: [link]. It helped me not miss any crucial components in my setup!
Just to clarify, do you mean 40kWh daily? The average U.S. household uses about 29kWh a day. Depending on your situation, if you go for net-metering, it can be really beneficial as the grid can act like a free battery. I'd recommend micro-inverters, like Enphase, since they work well with net-metering. If not, consider an off-grid hybrid inverter. I installed a 6kW system that cost me about $5k in parts and it’s working well. Avoid door-to-door sales and lease deals; local installers with good reviews are usually your best bet.
Before moving forward, make sure to check your local regulations regarding grid-tied setups. There could be specific permits and qualifications you need to consider which could affect your choices significantly. Also, if your utility offers net-metering, that could be beneficial.
