Solar Panels

Typically when we say "solar panel" on a boat we mean a photovoltaic module (PV module). A PV module is a packaged, connected assembly of solar cells in an array which can provide an output voltage (typically in the 12 - 24 volt range).

The main types of PV modules in use on boats include:

• Polycrystalline modules packaged under glass
• Monocrystalline modules packaged under glass
• Thin film modules on a steel or flexible substrate, without a glass coating

Wind Generators

Tow Generators

Charge Controllers

MPPT Controllers

Personal Notes

• Delatbabel -- I have 4 solar panels aboard my boat:
  • 2 x flat 80W panels, "Lensun" brand, on top of the doghouse roof. I purchased these via eBay. These run in parallel into a 15A MPPT controller.
  • 1 x monocrystalline panel, 75W Kyocera, This runs in parallel with a wind generator and a tow generator and goes into a 15A MPPT controller.
  • 1 x polycrystalline panel, 200W Solraiser. This runs into a into a "Morningstar" brand PWM controller.

The panels generally give pretty good output. I'm impressed by the Lensun panels, I walk on these a lot because I need to get up on the doghouse roof to set and unset the main sail, and they still produce quite a lot of power. I'm less happy with the Solraiser panel, the peak output from it appears to be about 4A and it is a lower voltage panel (peak output at 12V compared to say 15V for some other panels) meaning that it's less easy to run its full output via an MPPT controller into a 12V system. 2 of these in series might have been a better option. IT seems to do much better running into a PWM controller but really only gets up to full power when the battery voltage is quite low.
