solar recommendations

Looking for good solar panels. Recommendations?

It is for a Bristol 24. It has space on the hatch, transom outboard well, and forward hatch.

Energy Plan
- Two Batteries: 120 amp hrs (total for both batteries)
1. Tiller Pilot (TP22)
2. Depth Sounder
3. Knot Meter
4. iPad
5. Garmin Glo (Blue tooth GPS feed to ipad)
6. Radio w/AIS (Standard Horizon GX 2150)
7. Navigation lights
8. Interior LED's

I currently have one portable, foldable 25 watt panel.

Re: solar recommendations

What region do you sail in, what times of year do you sail, and how often do you want to plug into shore power?

A 50w panel with a good controller (like the Genasun MPPT) would probably be more than enough.

Re: solar recommendations

SF Bay Area. Want it to be offshore capable. Say SF to Hawaii. Will look up Genasun MPPT. Any recommendations on the 50W panel brand and vendor?

I agree on the Genasun - you won't find a better small panel controller.

Which batteries are you using that only have 60 AH each?

Re: solar recommendations

Haven't bought the batteries yet. Thought I would throw in some specifications or it would be pretty vague question. Am leaning towards two 27 batteries which are 90A each. I am guessing that they will take on and release charge when going from 80 to 50% and then charged back up to 80.

Still interested in a manufacturer/vendor for the panels.

Re: solar recommendations

With solar they will charge past 80%. 100% if enough sun with little DC use.

Lots of good brands of panels. I would avoid E Bay and buy from a reputable solar retailer in your area.

Re: solar recommendations

I have heard that some retailers can be as little as $1/watt. Also, wondering about the other specs: weight/height etc. Are the ones for marine use different?

Re: solar recommendations

There is no specific marine solar panel really. They are all designed and built to withstand the elements.

Buying at $1 a watt leads you to the bottom of the barrel in quality in most cases. $2 to $3 a watt is more normal I think, maybe $4 a watt for flexible panels like those from Go Power.

The other issue is panel size. The price per watt drops as the panel gets larger but you probably want a small panel - somewhere under 100 watts.

Re: solar recommendations

Sunforce seems to have 80, 100, and 150W for 12volt systems. No other options at this site. Sunforce 100 Watt Crystalline Solar Panel
