Just finished the solar
panel install on our Jeanneau
49 and it's working great. We have six 100 watt semi-flexible panels
mounted on the bimini
in a series parallel configuration feeding through a DC circuit breaker into a Victron Blue Solar MPPT
controller into the house bank. The Victron controller has a bluetooth interface and app so we can monitor
system performance on a smart phone
I bought the panels
on Amazon. 100 ETFE fiberglass
backed semi-flexible panels by GeeSonic. They were $184 each. I think the price
now is a little higher but substantially cheaper than Solbian. I think they work
You'll note we have a really big bimini
. In retrospect we could have fit the larger 150 watt panels in the front two sections of the bimini.
I'm amazed that this setup generates power from pretty much sunrise to sunset - even on cloudy and overcast days. I had 5 amps coming into the batteries
at 8am this morning. This is exactly what we wanted - now we can leave the fridge and freezer
running while the boat's sitting at it's mooring
I thought I'd share pictures of the install and answer any questions you guys might have. While planning this system I picked the brains of numerous experts on this list. They were incredibly helpful.
Here's are some pictures of the panels mounted on the bimini. The panels are fiberglass
backed so our canvas
shop was able to sew zippers on the sides matched to zippers on the bimini with UV covers to protect the zippers. I also had the canvas
shop create raceways for the cables
. The raceway flaps close with velcro. The raceways are a little tight. I didn't figure on the diameter of the MC4 connectors. But they do close and it makes for a neat installation
- no wires flopping around.
If you look closely you'll see all connections are numbered and the panels are labelled so everything goes together properly when assembled on the boat
. The panels were installed and wiring
connected in stages as the bimini was being put up for the season. Definitely a two person job. Three would have been better.
We have the three panels on each side running in series and then the two sides come together in parallel. The thinking was that each side would be at a different angle to the sun but between the two we'd maximize power during the day. Each panel is rated to generates 20 volts and a max of 5 amps. The Victron app says we're getting pretty close to the expected 60 volts and so far we see a maximum of 7.5 amps - or 435 watts to the controller and house batteries
