Panels are a most always connected in serries for really high DC voltage when used with grid tie.
For my first solar power install I was going to run panels in serries for about 572 volts DC open current making about 400 to 450 volts DC under load.
Grid tie inverters cost about 10 cents per watt of capacity.
No need to reinvent the wheel.
If one cell in the serries gets shaded the array output will just about be cut in half.
If the panels are in parallel, say running to a 48v inverter one or 2 panels getting shade won't effect the entire array much.
But the cost per watt of 48v inverters is much higher than 100 to 600 volt inverters.
