RICH SOLAR 200 Watt 24 Volt Moncrystalline Solar Panel High Efficiency Solar Module for RV Trailer Camper Marine Off Grid

I've been using these panels for 3 years. They give great performance, and in accord with their specifications. Many of the reviews here complain about voltage being higher than 24V. They are suitable for charging 24V systems. That is an entirely different thing than saying these panels will always put out 24V. Here are the specifications for this panel from Rich Solar's web site. Voltage at max power: 36.3V Open circuit voltage: 43.5V (a.k.a. Voc). Temperature Coefficient of VOC -0.28%/°C (This means Voc will increase when it gets cold). Yes you will see 43.5V when it's sunny, your battery is full, and your charge controller stops flow of current into the battery. If it is cold you will see even higher voltage, specified by the temperature coefficient value in the specifications. I routinely see 72V during charging when I connect two of these panels in series. While this won't work well for a Bluetti unit with an input voltage limit of 60V (as one reviewer here described), it works great with any of the MPPT controllers on the market that can take 100V or more, as it has for me for more than 3 years now. If you want lower voltage, check out the specifications for Rich Solar's "12V panels".

I purchased this item almost 2 years ago and decided it was time to do a review on it. Most of the time items that I buy seldom meet the advertised specifications. In this case it is quite the opposite. I just took a reading on the voltage output of the solar panel and to my amazement It was putting out 41 volts with an advertise maximum of 37 1/2 volts. I am completely happy with this solar panel and plan on buying more in the future.

Works great doubled my solar output only had 400 watts before.

These are decent, I’m pulling a little over 500w with four of them. At around $200 a piece you can get more bang for your buck elsewhere. I bought 4 all together and would have returned two but I didn’t want to deal with odd sizes from a different brand.

Looking for Rich Solar M-200D panel. In the description it says"RS M-200D" however an RS M-200P (or Pro) came. I called Rich Solar and they confirmed it is just an upgraded panel and is compatible. However, it does not look like the M-200D in appearance, close, but not exact so they will not match if that is an issue for you.
