Weize Solar Panel 100 Watt 12 Volt, Single 12V 100W High Efficiency Monocrystalline PV Module Power Charger for Home, Camping, Boat, Caravan, RV and Other Off Grid Applications

I added this 100 watt panel to my 2 panel Renogy 200 watt string because it was priced cheaper. It is working great and seems sturdy. I now have a 300 watt setup and It's charging my batteries good. This panel is a little smaller then the Renogy's so it may be a better fit to save space on an RV or camper. I'm happy with it and would buy again.

works great on my rooftop, generating almost 100W at noon, even I didn't place it at the best angle.

Got it for a couple of weeks and it's up and runs pretty well. We use it to power our DC well pump that is used for watering our garden. Free water + free electricity = smiling face. Hope it could last for 10-15 years.

This is a very good panel. It puts out what it says it puts out. Having said that, I own a number of solar panels and a couple like this one in the 100 Watt range. While this panel is a well made panel that lives up to its specs, its no better(or worse) than the two other brand name 100 watt panels that I own. The only difference is normal asking price. I bought this panel for about $79 I think? But it normally goes for $99 minus a $10 coupon so $89. The normal price for the other two 100 watt panels I own are between $75 and $79 each. In fact, the only reason that I bought this panel was that it went on sale for $79 so I thought Id try it. Like I said, its a good panel and Im glad to own it but I feel its a little over priced at its normal asking price. I give it 5 stars at the price that I paid for it but if I had paid more, I woulda considered it a 4 star because of being over priced.

I bought this 12vdc panel to drive my 12vdc variable speed pump motor that circulates water through my roof top hotwater heat exchanger. The old panel would drive the speed of the pump based on the voltage sup upplied by the PV panel. This worked when hooked directly to my pump but after and hour the pump quite running. It smelled hot and I feared it had burned out. I still worked onm my 12vdc power supply so good news. next I added two buck modules in series. The first set to limit the output to 18vdc and the second set to a limit of 12vdc. The pump has been working as expected and draws 60mA of power from the panel. The buck modules are rated 2 amps so I hope this setup continues to work. Full sun in south Florida produced a high of 22 vdc from the panel.

Installed 2 panels to the roof of our van, they keep 1 battery charged (which runs our fridge). I ordered a 3rd panel to add just to keep my wife from worrying about not being able to run her little fan. As of right now, we don't run much more than our fridge or her fan but son-in-law says we have plenty of power. The panels came in good sturdy boxes with styro-foam cushioning, no damage and they hooked right up. Do not hesitate to purchase these!

Recently, I purchased four of these panels. Three arrived in a few days with Free Shipping, but the fourth unit never arrived. Amazon gave me the option for a refund or re-order within a few days of being overdue. I opted to wait and see if it would eventually arrive, which it did not. Amazon then automatically refunded my purchase on the fourth unit after about a week. In regard to the panels in operation, I am very happy with the quality. I hooked a 300 watt dump resister to each unit upon arrival for testing. I am pleased to say that my reading (volts x amps) showed 108 watts when the panel was pointed exactly at the sun. Otherwise, the panels give an average output of about 80 watts in full sun with a clear sky. This is expected and certainly acceptable. Please note, these panels cannot tolerate any shading whatsoever. If there is any small or slight shadow blocking the sun, it will greatly lower the output to almost nothing.

Solar panels keep dropping in price, I decided to do a small setup for fun at my house ive got two of these panels. They are sturdy and have mounts on the frame that fit the universal mounts im using. I cant say how well they will stand up to weather over time, but they do have silicone sealant and the wiring has a weatherproof box.
