- Best for
- Roofs with uniform, unshaded orientation and owners who want a single, centrally serviceable inverter.
- Tradeoff
- The central inverter is a single component that, if it fails, affects the whole string until serviced.
- Durability & upkeep
- Power optimizers at each panel mitigate shading and mismatch losses while keeping conversion centralized.
- What drives the cost
- Inverter capacity, number of optimizers, and overall system size.
- Choose it when
- The roof has consistent sun exposure and centralized servicing is preferred.
