Renogy 50W Portable Solar Panel Charger Review

0 186

The Renogy 50W Solar Panel is a 12V compatible unit that can generate up to 200Wh on a sunny day. It is the perfect size to hold or adjust effortlessly. You can use this panel to power small batteries and you can install it in small spaces near your tent or motor home. It comes with tempered glass and a lightweight, rust-free aluminum frame. The cables have the default MC4 connectors, which makes the setup process easy.


Among the important features of this Renogy 50W Solar Panel is its monocrystalline cells. They are more efficient than polycrystalline cells and reduce the size and weight of the board to obtain the same power rating. The aluminum frame and tempered glass are standard but basic features. There is a diode on the side that can bypass the shaded cells to conserve voltage. In simpler words: partial shade does not affect power generation. Since most Renogy products are described as portable, the board should have a mounting bracket, preferably built into the frame.


50 watts may seem negligible for electrical appliances like refrigerators and televisions, but as long as small and basic power requirements are in question, they don’t fail. It can power small to medium size batteries such as 150 Wh batteries, DC lamps, and fans. For more power, multiple panels can be connected in series or parallel, depending on the voltage requirement. Connecting up to 3 panels can generate more than 500 Wh per day, which is a significant amount. The panels are fully compatible with Renogy’s range of battery terminals and can even be purchased as a package.

The Renogy 50W 12V panel comes with the cell array sandwiched between the TPT back sheet and the tempered glass. This makes the unit strong enough to withstand winds, snow loads, and even minor bumps. The body is made of non-corrosive aluminum, which reduces weight and the chances of rust. The body of the unit is waterproof and can withstand even the strongest rain because the junction box comes with an IP65 rating.

Easy to Use

Positive and negative cables have been precisely connected to this board with pressure suitable MC4 connectors as standard. These connections are easy to connect and no wire cutters or wire strippers are required. This improves water resistance and reduces energy loss. MC4 connectors can be connected in seconds to the charge controller or other patch panels.


Renogy decided to keep doing the basics perfectly rather than working on the look of this palette. The laser-cut black cells are carefully placed together, and the gray frame and white back panel give them the look of a typical solar panel. However, it has an excellent fit and finish. There are no broken or misplaced sealing parts and the frame parts are precisely fitted.

With technology offerings, it’s often more important to get the essential features completely right than to invent new ones. Renogy 50W Solar Panel does the same here with tempered glass, Al frame, and bypass diode. 25-year guaranteed power generation makes the board a reliable product. If you are looking for a practical and lightweight board that can run small to medium devices, the Renogy 30W 12V board is a perfect choice.
