We swapped the four 200 W Rich Solar panels on Sophisticated Lady's side rails for four BougeRV N-Type 12V/24V 200W Solar Panels. Same rail, same 800 watts on paper. Then we watched the Victron numbers for a month. The old set averaged about 1.2 kWh a day. The new set averages almost 3, and on a bright day it peaked at 918 W, more than its own rating. The difference is shade: 24 bypass diodes per panel, N-type TOPCon cells, and a bifacial back that catches the light off the water. Three panels arrived. The fourth box held a computer desk.

WHAT WE FOUND
• Same rail position, same 800 W nameplate: 4 × 200 W Rich Solar out, 4 × 200 W BougeRV N-type in
• Daily energy: about 1.2 kWh a day from the old four (29-day average) to about 2.9 kWh from the new four (19 days, cloudy and rainy days included), nearly 2.5×
• Peak power: 363 W to 918 W, above the 800 W rating
• Best day: 1.87 kWh to 3.93 kWh
• Day one: two new panels alone peaked at 435 W and made 1.88 kWh, more than all four old panels ever did in a day
• Why: one shadow from the rigging used to drag the whole series-parallel circuit down; with 24 bypass diodes a shadow only costs the cells it covers
• Still to come: a long-term report after a few months of sun and salt, and the dinghy bimini's own output test
