Which type of solar panel is the most effective, polycrystalline or monocrystalline?
1074724
If you do a little research you will find that the monocrystalline panel is more effective. The last few years polycrystalline panels have become a lot more effective. For the size and application a 95 watt panel you will not see much difference. I have the go power system installed on my 5thwheel rv and love it. Keeps my batteries charged while not in use and allows us to go for a solid week with no power with out a problem. With 4 people in the trailer on one battery that is pretty good. Going to a 2 battery system this year using the panel to charge the battery not in use. Should be able to go 2 weeks easy. Good luck!

This site: http://www.earthtechproducts.com/solar-power-panels.html (scroll to bottom) has a good description of the different cell types, advantages and disadvantages. In general, mono- is more efficient but also more expensive than poly-. However, efficiency for mono- cells falls off more with increasing temperature than poly- cells. In higher temp setting (e.g., southwest desert), the poly- cells may yeild higher efficiency.

I have the mono which seems the most popular....Full sun keeps batteries at full power and always charged when I hook up.I like this one and Go Power was easy to install.

yes, 5-17 voltsMine is working great and i have placed it between the solar panel and the voltage regulator.MPP

You need to fully charged your Deep Cycle Battery. Connect your HQRP 30W Flexible Solar Panel and face it towards the sun where you have approx 8 to 10 hrs of sunlight daily . Also I have a Sunright 7 amp Solar Charge Controller for double protection of overcharging. I use it for my Battery Portable Solar Generator, and My RV's House Batteries (trickle charging)

They have a pane of glass in front of the solar cells which could break, especially if hit by something. I think all panels of this type do. You might be able to take the frame apart and replace it with plexiglass. If you want the toughest, the roll-up flexible panels from Unisolar are less efficient and more expensive but appear to be nearly indestructible.

This is the one I recommend to those who have solar panels as it is least likely to damage the glass.

For one panel I use a 7 amp in line charge controller.The Sun Force 7 amp controller, which is available on Amazon for $14.01, has worked well for me.It also contains a diode to prevent the battery from discharging at night.The max output of the panel is about 3 amps.

The R15-300 is a 5w panel in full sun. PowerFilm offers rollable panels up to 60w for sale on Amazon.

The solar panel is plenty strong. There are no weakness issues in the design I can see. It's really been useful camping since it also will charge cell phones!

Hi Raymond. The solar panel details are such: 2.5Wp, 7.8V polycrystalline solar module. I would suggest staying at our below these levels.

Plate looks stainless, body hard plastic and some of edges rubberized to prevent slippage. Well engineered. Picks up stations well including weather. Good battery life with solar help but also can be 110 volt charged. Have only cranked when on boat where no power available. Would buy again but not probable as still working great after two years.

Seems like Mamdogtag has no idea one comment he says it's Mono and the other he says Crystalline. To me they look like they are Polycrystalline Silicon Solar Cells

Mppt would work better because it does peak power tracking of the solar panels. This provides a significant efficiency increase in the power output of the solar panels. There is more information about it here: http://www.morningstarcorp.com/en/support/library/Trad-PWM-vs-TrakStar-MPPT-April-2013.pdf

Light weight solar film mounted on a piece of plexiglass. There are some marine panels that are even more flexible, see West Marine. I thought the price on this was pretty good. Hope this helps.

This is a solar panel. Mistakenly, they are describing a different product.

The solar panel is on top. The only one I found with the panel integeral to the unit.I have it installed on the West wall about 10 feet up. This is a two-story brick home with a big tree in front, overlapping this aide.I'd estimate that it only see's direct sun for ~3 hrs per sunny day.It worked immediatly. I've been showing my neoghbor, and he bought two for the West wall of his house.NO complaints.... Well made...You'll be very plesased !

Yes, but you want to face the solar panels towards the sun so it gets the most direct sunlight.

Hello JDT,The Renogy 40 Amp MPPT Charge controller can support up to 3 of the Renogy 250 Watts 24V Monocrystalline panels at 24V
