I got solar panels installed this fall. 700 watts on the pilothouse roof.
I bought the four 175 watt flexible panels from Renogy and installed a Victron Smartsolar 50/100 controller. This connects via bluetooth to my phone to a slick app.
I put a Victron Smartshunt on the house bank as well. Ran the boat on just solar for a week or two and no problems running the fridge, lights etc.
To mount the panels I used VHB tape, the thickest available. I ran strips parallel to allow some air flow for cooling.
I’m very pleased with the result. The panels are very unobtrusive, and will allow me to live at a mooring comfortably.
Total cost was about $2,000.
