Review: Definitely good panels - I feel like I have enough experience with these panels now to write a review. I’m not going to be overly technical or anything because I don’t have that type of background or ability. I’m just going to tell you my experience and how they’ve worked. I’ve ordered these panels three times and I’m ordering another two now. My first order one of the panels was shattered. I contacted desertcart and they sent two more panels out and did not force me to send the other panels back. Meaning I got three panels that were working even when I’ve only ordered two at that point. I expanded the array by ordering more panels. And again expanded by ordering more yet again. One order was damaged out of three, not to mention the replacement that they sent which can be considered a delivery or order if you want so four deliveries with one panel damaged. In total, I have eight panels. I’ve had these set up 2 series 4 parallel, 3 series, 2 parallel, 6 series, and 4 series 2 parallel. All worked as expected and excellent. Right now I have 4 series 2 parallel, which is sitting at about 120 something volts as my new inverter requires 120 V before the MPPT makes use of PV. This is why I’m ordering two more so I can do five series 2 parallel and be well within range for my MPPT. That said eight panels is 2560 W, after inverter and light load of about 200 W I am getting about 1950 W into the batteries after load. I would say that pretty nice for the panels. When I get the two more panels, it’ll be 3200 W and based on my experience thus far I expect to get between 2400 and 2600 watts charging my batteries daily, slightly more actual wattage running inverter and light load. The connectors on the back of the panels are easy to work with and seem to be very well-made. All the seals and seems everywhere with the wires and the seal to the frame seem to be well done. I happen to be very lucky to have the extra panel that desertcart sent me when one was broken because of the wind storm that shattered a panel that was in the active array. So of 10 panels that I’ve had eight survived. One died in shipping, one died in the line of duty. I’m very happy with these panels. I wish they cost a little less, but they are reasonably priced. I get five stars because the shipping incident was taken care of and the panels have been performing very well in many different configurations. If I had to do it all over, I would have ordered all the panels in one shot instead of making multiple orders. However, it’s worked out and I am happy with the purchases panels have been working for about two years now.
Review: These panels perform - I purchased this for a van build. On the first trip, we spent 9 days off-grid. It worked awesome. Even on cloudy days we were receiving a great amount of charging power. I paired it with (3) 300Ah batteries running a 12V AC with inverter for appliances. It recharged the batteries well each day. We were never without full power when traveling due to a near full recharge daily - even with a few days of rain included.

## Questions & Answers

**Q: What do I need to complete my off-grid solar power system ?**
A: You need a solar panel, a charge controller to regulate current, and a deep-cycle battery for storage. For wiring, you will need adapter kit cables (panel to controller) and tray cables (controller to battery) to complete the system.

**Q: What does off-grid and on-grid mean ?**
A: On-grid means connected to the power grid. Off-grid means independent of the grid, storing power in batteries for later use, so you are never affected by grid blackouts.

**Q: Why is my solar panel under producing ?**
A: Solar panel performance may be hindered for a number of reasons. Most commonly environmental conditions such as indirect sunlight, temperature rise, cloudy sky, and dirt and stain build up on the top glass will cause a reduced power output.

**Q: How should I connect solar panels in my electrical circuit (series vs parallel)**
A: Connect in series to increase total voltage (current stays the same), or in parallel to increase total current (voltage stays the same). Combine both for optimum system power output.

**Q: How many solar panels do I need ?**
A: First, determine your total power load (Watts × run hours × 1.5-2 safety factor). Size your battery bank based on this capacity, and accordingly decide how many panels or how much power input is needed.

### ⭐⭐⭐⭐⭐ High quality and reliable
*by D***S on April 23, 2025*

High quality solar panels that perform well. By purchasing a package of two panels, they are a better value. I have used different Renogy solar panels for the past ten years and have found them reliable and easy to mount and install on my RV's without adding too much weight. I will be using the new 320 watt solar panels on my off-site storage building.
