I spent the last few months sourcing panels, inverters, and batteries for a DIY home solar kit business, and the biggest thing I learned is that most people overbuy.

You don't need a 20-panel whole-home system to start seeing real savings. A 4-panel starter setup with a hybrid inverter and one battery can offset a big chunk of daytime load — dishwasher, AC, fridge, chargers — and it pays for itself way faster than people expect because you're not trying to zero out your bill on day one, you're just cutting the peak-usage hours that cost the most.

The other thing: mounting hardware quality matters way more than panel wattage. Cheap rails and flashing are where DIY installs actually fail — not the panels themselves. Spend the extra $40 on proper flashing.

Built Helios Hardware around that idea — starter kits sized for real usage, not sales-pitch numbers. Happy to answer questions if anyone's looking into going solar.
