Wiring solar panels straight to breaker panel?

"Renogy Tracer 4210" So, no remote battery voltage monitoring. You may lose a couple percent in power by mounting it remote from the battery, but things will still work fine. There's a lot of dogma out there from the days when panels cost 4 times what they do now, and people were anal retentive about efficiency. Don't be that guy. If a couple of percent makes a real difference, you'd want another panel anyway.
