Newpowa 35W 24V High-Efficiency Monocrystalline Solar Panel - Designed for Off Grid Systems, Charges 24V Batteries of RV, Boat, Camper, Trailer, Gate Opener

24v small form factor for the occasional light maintenance charge of 24v battery(1.5KWh) and big power station (2KWh). It's not enough to recharge those in a heavy drain situation due to long power outage. That's the job for larger panels. High enough voltage to meet the MPPT charge voltage requirements for my systems.

**Update 3/2024**Never got a chance to put these 60W panels to the true test in the desert, had not yet figured out how to fit them in the already overpacked car for Boondocking. The 2x50W version of these I made into a suitcase performed extremely well. Placed rocks under stands to prevent desert winds from blowing them over. Finally got these 60W panels out of storage to add stands to in the same way, and found one junction box damaged. Hadn’t noticed it when I first did testing. Contacted Newpowa support and they have stellar customer service. They were unable to help with parts for this older 5 busbar model, but shipped a new replacement 9-busbar panel. All 3 panel types are in the latest picture. Tested very well in SC sun. Have new car storage setup for more panels. Will attempt a desert trip soon. Great panels and support.**Original Review**I really like these solar panels. These 2 60-Watt 24V panels are going to be my second DIY suitcase. 28” x 20” 11 lbs each high quality mono panel was my decision maker for me. My first 2 panels are the 50-watt 12V version of these from a year ago 23” x 20” 9 lbs each original decision maker to fit in car. I use those in series for higher voltage to a EPEver Tracer 30A (see Will Prowse YouTube videos for more info). Those are great little panels, and I regularly get 90% or greater power in good direct sunlight, New York summer or Carolinas winter. These new 24V panels Vmp-33.54V is equal to the 2 x 12V panels in series, so they should parallel with that suitcase just fine. I have been testing great for a few tests, 115watts from 2 60-watt 24V panels parallel via MPPT into LiFePo4 12V 100ah battery nearly topped off. I will try to update after extensive testing and use.

Bought it for my electric gate opener. It worked great

A good panel. Make sure you tighten all connections before putting it outside. Wasn’t too happy they don’t have anymore in stock. I hate mixing and matching panels and would like the same one.Panel is solid and puts out good power on a sunny day in upstate NY.

4 Panels - put out around 115-125 V on an average day - 3.9A / .5 KW / 4.3 KWH / ... Using a Sungold Inverter on a bank of 16 6v golf cart batteries - to put out 48V.Yea - I started the project 5 years ago and at some point will rid myself of the golf cart batteries when they start going bad.My Rivian R1T electric truck - if I use the slow L1 charger - says it's charging at 1.2kW - - - so..... Starting a day at full charge on the 48v batteries - running the inverter - and as the Solar Panels continue to add juice to the batteries - - - - On a sunny day will drain the batteries after about 8 hours - and I have to unplug my truck and let the batteries charge back up.30 miles +/- will be added to my truck for the day - 200 miles a week sort of.... from the sun.Goofy thing I did was doubled the wires from the 50 foot run from the inverter to the panels - I saw a change from 1.9A to 3.9A / .3KW to .5KW - yea that's not code - whatever.... I did it to test it - and now will order a thicker wire and replace that run.Will it ever pay for itself NO - I probably spent $5k on the setup could have paid my light bill for a year with that - but that was never the point.Hurricane season? - I'm good - tied the system into my one room in the house I use as an office - and my battery bank runs my outlets / computer / tv / internet etc - 24 + hours with zero sun.What did I learn? - don't waste time on 100 watt panels - or 12/24 volts - go 200 / 48 v and buy a nice inverter up front so you don't throw away the one you tried to save money on..... and run the thickest wires you can. Buy the new good batteries for sure.

Great value and excellent build for a budget. Using a MPPT charge controller I can output double the amps of a similar sized 12v panel. I use this to keep the house and starting batteries on my Pontoon charged while moored at the lake. Only critique would be the frame construction being single walled makes it flex more than I’d like going down the freeway on the trailer.***Update: I’ve had this panel in operation for about a year now. Second two images are after a year being mounted to the boat. It stays on all year in all weather. It has been flawless in operation while moored at the lake and while parked in the driveway. After a day on the lake just anchored and listening to the stereo (6ch 600w MBQuart system,) running the chart plotter/ fish finder, and charging cell phones and I pads for 4-6 hours, this solar panel recharges the house battery in less than 12 hours, about 30ah at 12v. We’ve never left the dock with anything less than a 100% charged battery each day. In some cases on a bright sunny day it will run the chart plotter and charge devices while still adding charge to the house batt. No issues at all with this brand or it’s performance. It’s also handled multiple freeway trips at 65+ mph for several hours with zero issues.Highly recommend!

The original panel was delivered without flaw. However the product did not function as described. Plenty of volt capability, no current (watts. 0.0). Returned with shipping a replacement panel, however this panel was performing weak again plenty of voltage 7 watts of current.. However panel failed again soon after no watts plenty of voltage! Long and short- the panel has one bad diode. 15v 45a. 15vSQ045 pair of diodes. Panel produces good voltage up to 41 volts I am returning the product again asking for a refund!
