  • FANTASIC DEAL***** 150W SOLAR PANEL
    August 23, 2014 03:41 pm
  • @Xizang:  A panel that I don't recommend is the Renogy 100 watt mono crystalline.  I  bought eight of them for my 2nd array. They do function,  charge and are well made but, on the best days they are charging around 15 to 16 volts while at the same time the the eight  Ramsond 100 watt panels in array #1 are charging at 19.7 volts. The Ramsond's  cost more, but they really are work horses.  Both  panels charge  about the same in low light conditions,  dawn, dusk and when it's cloudy.

  • Look for panels with MC4 connectors for starters. They are water tight and that will prevent that problem. Rest of the panel itself should be well sealed if quality. There are spray sealers that could be used on the backs of the panels too.   Those eco worthy panels are Chinese, who handles warranty claims inside the USA?  If you have to ship it to China what warranty? Shipping will be more than the cost of a new panel. One reason I went with Solar Cynergy. They have a CA office for warranty claims and I don't care what brand of panel you get it is possible to get a bad panel with a cell that has a hairline crack that later fails, or a bad solder connection inside the panel....

  • The last sailboat I owned had a solar setup on board.  Simple, actually.  A panel mounted aft hanging outboard on a railing.  The 12 volt output ran down below to a deep cycle battery, which was the 'house' battery supplying 12 volts DC throughout the boat to run radios, lights, etc.  There was a small inverter that also drew off the 12 volt battery, and supplied a 120-volt AC electric outlet in the galley for small appliances like a blender or whatever.   The mountain cabin was much larger and with two inverters, which provided 120 volts AC, as well as 240 volts AC for the 240-volt water well pump.   She also had a standby gasoline powered generator, in case the solar system took a dump.

  • @Xizang: Oop,  forgot what to recommend.  I would recommend these very panels we've been discussing. The Eco-Worthy 150 watt mono crystalline panel for 140$ from their website. http://www.eco-worthy.com/catalog/130w-150w-solar-panel-c-129_89.html     QUITE A GOOD DEAL

  • @Mary_B: I  found Solar Boulevard,com . The do indeed have good deal for poly crystalline panels. A 140 watt is  154$ for 1 panel or 144$ if one buys a 2 panels bundle, not bad.  Eco-Worthy does have a slightly better price of 140$ for a 150 Watt mono crystalline, a saving of 14$ and 10 extra watts.  I clicked on their 150 watt poly crystalline for 121$ and found they no longer sell them, sorry about that. @Xizang: I really don't know about marine solar systems but, all solar panels should be impervious to weather.  Be sure the panels have the MC4 connection cables, not the regular connector wires found in some panels " like what they sell @ Harbor Freight" There are special marine power inverters made to a higher standard for dealing with salt air environments.

  • From what you guys know, are there any you would especially recommend for heavy use outdoors, in LOTS of water?   I'm asking because I am around large boats, marinas, and an environment where there is not only water from the skies, but sea water splashing up big time.   Live aboard boaters are always looking for better solar panels that won't crap out in salt water spray or too much sun.

  • Okay anything I add a link to is not showing as part of the discussion, Solar Boulevard has the 140 watt panels I use. I have 16 of them and the company that produces them is US based(some panels come from china but are built to better specs). Solar Synergy is the brand name

  • Testing .... for some reason my posts are not showing I have 16 of these, US based company so better warranty service http://www.solarblvd.com/Solar-Panels-&-Systems-12-Volt-Solar-Panels/c1_269/p2668/Solar-Cynergy-140-Watt-12-Volt-Solar-Panel/product_info.html

  • " Decent price, never heard of the brand, but made in China. I use these, little higher in price but a USA manufacturer who also has a plant in China so it likely is chinese made but to a higher specification http://www.solarblvd.com/Solar-Panels-&-Systems-12-Volt-Solar-Panels/c1_269/p2711/Two-...

  • www.solarblvd.com has reasonably priced smaller panels. And the company that builds/imports them is US based for warranty issues http://www.solarblvd.com/Solar-Panels-&-Systems-12-Volt-Solar-Panels/c1_269/p2668/Solar-Cynergy-140-Watt-12-Volt-Solar-Panel/product_info.html are the panels I use. I have 16 of them with 8 in use and 8 waiting to go up as soon as I have cash for the framing.

  • @Xizang: They all do pretty well and are rated for about 25 years. A typical 12v panel doesn't really produce 12 volts. They run at about 20 volts, the watts/amps  are a little higher too. They do this knowing that they need extra so they can continue working for 25 years.  Also they want to make sure that they can charge a battery when less than ideal conditions are present, I.E. perfect sunlight. This is why one needs a charge controller with their panels. So that during good conditions one doesn't over charge your battery/batteries.  I use 50 amp/800 watt charge controllers which is why I mentioned 800 watt arrays. That is just how I set my system up to run.  You may want a different configuration. That's the beauty of solar, there are so many ways to customize a system that's just right for you and it's easy.

  • I married a gal who had a cabin deep in the mountains of Colorado.  Her previous husband had set up a shed/well house/battery room with solar panels on the roof.  With two invertors and a battery bank, they powered her water well submersible pump as well as lighting and electrical outlets in the cabin.   I had a problem with her system running low on juice in the evening, and thought of improving capacity.   Do any of you know which type of solar panels produce the highest wattage as they age?  It seems that as they get older, many solar panels drop way off in output.   Of course, you need to maintain/replace as necessary your storage batteries.  (She had a bunch of electric golf cart batteries)

  • RRG  I see the benefits We have no outside ground to place panels.   We have 2 balconies and live at 7000 ft, 310 sunny says a year even in winter  so the panels would be space limited as we are in a mountainside condo complex   But 400-600 watts is decent    charging a set of deep cycle batteries with an converter would power small appliances  lights and other stuff  Thi s is a good deal

  • I know Mary_B uses solar, but I haven't seen her in a few days. As I have been building my generator a little at a time I have learned a thing or two about them  and can honestly say this is a really good deal.  Normally 800 watts will cost about 1100$ to 1200$ for bargain priced panels, 5 of these would be 750 watts for 700$ a saving of around 500 bucks! That's almost enough to build a second array.  The poly @121$ would build 2 arrays for the price of one.  I prefer the mono because they are  better in low light. Where I live we get a lot of cloudy days so mono is the better choice.
