Review: Panel arrived in good shape with no scratches, frame damage or hairline chip cracks. Output in full late afternoon sun was as specified. Small enough for the smaller needs while still providing decent output. Panel supplied with bare wire ends, which was fine as I was installing PowerPoles, anyway. Wire lead length was about 2-3 feet long. This worked well for my use, as I didn’t need longer leads, and it’s less voltage drop with the shorter wires. I plan to use the panel to charge various 20Ah and 35Ah batteries for use with an inverter during short power outages. Also have a 110Ah AGM deep cycle battery and 100W panel that when used with a 2000W inverter will run the fridge plus some extras for about 10 hours. The smaller batteries work for backup while the larger battery is charging. Plus the 30W panel can be paralleled with the 100W panel for better output in less than full sun. In the last 20 years we’ve never had power outages longer than 5-6 hours, so the planned system will handle expected needs. Less expensive than a generator (about half the cost or less of a Honda 2000 and no maintenance). I realize that there may be cloudy days during a power outage, but fuel supplies also run low, generators break/need maintenance, and stored fuel needs to be cycled through to prevent spoilage. Still may get a generator in the future. Also use the solar panels/batteries as backup and portable power for my ham radios. The smaller batteries and panel work best for this, as the 110Ah AGM deep cycle battery is a bit heavy. This panel works great for what I bought it for. Before buying a solar panel would recommend researching what’s required for your planned use (power needs, battery size, length of your wire run, panel sizes, whether a 24V/48V system with a step down controller may be better than 12V if using longer wire runs, portable or permanent use, etc.) so you don’t spend unneeded extra cash or end up with a cheap panel that doesn’t work well for what you need. Review: I can't say enough how impressed I am with the quality of this panel. Currently its been very overcast and I've only had it installed 2 days, but its putting out plenty of power for what I'm using it for. I have it hooked to 4 computer fans to vent the garage. At 10:30 AM with totally cloudy skies it was putting out 0.43amps and 15.3 volts to the fans. I will probably put higher amperage fans on to drop the voltage some. Update: I installed higher speed fans to use more of the power at 12:20PM with mostly sunny skies the panel is putting out 19.5 volts DC at 1.05 amps to the fans. This equals 20.5 watts at a voltage higher than the max power is rated at so needless to say I'm very impressed. These fans are rated at 121CFM at 24volts and I would guess at 19.5 they put out roughly 100CFM. I have four of them connected so I now have ~400CFM of high static pressure air flow for free :). It was packed perfectly my only warning is the taped side of the inner box had the glass towards the seam which I wouldn't have expected. I was very careful when cutting the tape, but if you were careless you could scratch the glass. The panel frame is very sturdy I made 2 notches in each in so I could mount it using hose clamps to a clothes line and this worked perfectly. The ends are double walled aluminum so you don't want to drill any closer than 1/4" from the end which I found out the hard way on my first hole drilling into the out double wall. The wires and sealing on the panel were all well done as well. There is a little slide door that lets you see the wire connections. Currently I'm not using a solar controller but used ultra plugs on all my cable connections so it would be easy to plug one in. Online it said power output drops to 10-25% of max on cloudy days I'm seeing 24.7% of max power under cloudy conditions at 10:30 AM so I'm quite happy with that. There is no sun visible through these clouds so its very cloudy and darned humid on top of it. The panel wires don't have any plug ends which I wouldn't have used anyway as I installed ultra plugs (Deans plugs). They are perfect for small projects and can handle up to 30amps which in this case is way overkill. https://www.desertcart.com/Connectors-Battery-Female-Shrink-Tubing/dp/B01CWYFS4Y/ref=sr_1_10?keywords=ultra+plug&qid=1565546276&s=gateway&sr=8-10 So all I can say is super impressed overall. The poly solar crystals look so nice when you hold it sideways to the light I hated to mount in outside its practically a work of art lol. ## Features - 【New Design】High-performance 166mm mono cells encapsulated in EVA ensure excellent conversion rate up to 21-23%.

Factors affecting the performance of solar panels: Peak Sun Hours， Sunlight Angle， Operating Temperature， Installation Angle， Panel Shading, Etc... **Q: How to test a solar panel?** A: The ideal conditions: Noon, clear sky, 25° tilt to the sun, battery is less than 40% SOCC. Disconnect the solar panel from any other loads, using a multimeter to test the panel's current and voltage. **Q: How does temperature affect solar panel efficiency?** A: Solar Panel Efficiency & Temperature: -Test Temp: 77°F/25°C; -Peak Efficiency Range: 59°F/15°C to 95°F/35°C; -​Temp Impact: Efficiency decreases with temperature rise. ​-Example: Temp coefficient of -0.5% → Power reduces by 0.5% per 50°F/10°C rise. **Q: How to install our solar panels using different brackets?** A: There are mounting holes on the panel frame for easy installation using a variety of brackets. Most compatible with Newpowa's Z-mount, tilt-adjustable mount, and pole/wall mount, making panel mounting suitable for a variety of applications. **Q: Can I connect different solar panels together?** A: Though mixing different solar panels is not recommended, the mismatch can be achievable as long as each panel’s electrical parameters (voltage, current, wattage) are carefully considered. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***E on 17 December 2021* Panel arrived in good shape with no scratches, frame damage or hairline chip cracks.

Update: This thing works!!!! My battery has maintained a full charge since the original installation back in mid-May. The Newpowa panel has performed flawlessly! This was one great investment. I was a bit apprehensive about using a solar panel to charge my trolling motor battery--even though my boat is tied to a dock and sits in the sun daily. I was so wrong! The Newpowa 30w 12v solar panel works daily to keep my battery charged. I installed the solar panel along with an ALLPOWERS 20A Solar Charger Controller Solar Panel Battery Intelligent Regulator with USB Port Display 12V/24V in mid May and have not had to remove the battery or put it on a normal battery charger! And the trolling motor is my only means of getting around the small lake where I live and fish almost daily! All I can say is WOW! The Newpowa Poly Solar Panel has exceeded my expectations! Sooooo happy with this purchase! ## Frequently Bought Together - Newpowa 9BB 30W 12V Solar Panel High-Efficiency Monocrystalline PV Module Designed for Off Grid System, Charge Your Battery of RV, Boat, Camper, Trailer, Gate Opener - Newpowa Universal Angle Adjustable Mounting Bracket Single Arm Pole, Wall and Ground Mounts Up to 35W Solar Panel - Renogy 10 Amp 12V/24V PWM Negative Ground Solar Charge Controller Compact Design w/LCD Display for AGM, Gel, Flooded and Lithium Battery, Wanderer 10A --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/375195710-9bb-30w-12v-solar-panel-high-efficiency-monocrystalline-12v-pv](https://www.desertcart.sg/products/375195710-9bb-30w-12v-solar-panel-high-efficiency-monocrystalline-12v-pv) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-05-18*
