The short answer
Short answer: solid panels have no louvres at all, so they close to a near blackout and add the most insulation of any shutter, but you lose the tilt. Raised panel versions add a moulded profile that suits period rooms, cottages and panelled hallways.

What you gain
A solid panel closes to a flat face, so there are no louvre gaps for light or draught to work through. In a bedroom that means genuine darkness. On a cold north-facing window it means a solid layer of material sitting across the glass.
Visually, they read as joinery rather than as a window dressing, which is why they work in cottages, panelled hallways and period front rooms.
What you give up
The tilt. With louvres you can have daylight and privacy at once. With solid panels the choice is open or closed, so in a front-facing living room they can feel restrictive during the day.
The middle ground: tier-on-tier
Solid on the bottom, louvred on top is a common answer. You get privacy at street level, daylight above, and the panelled look where it is seen. Café style with solid lower panels does a similar job in a kitchen.
Cost
Plain solid panels sit close to a standard louvred panel of the same size. Raised and moulded profiles cost more because of the machining, and the finish quality matters more because there are no louvres to distract the eye.
Common questions
Do solid shutters block all light?
Close to it. There is a small line around the frame, but they are the darkest shutter we fit and far darker than a louvred panel.
Are they good for listed buildings?
They are frequently the more sympathetic choice in period property, particularly in a room that historically had panelled internal shutters.
Can I mix solid and louvred in one window?
Yes, that is exactly what tier-on-tier does, and it is a very common specification for us.
Do they warp more?
A larger unbroken face needs a stable material, which is why we would usually specify hardwood on tall solid panels.
