Our Verdict

After the comprehensive line of portable solar products by Renogy come the larger-sized, non-portable panels. The smallest of these is the 270W, 24V polycrystalline module. With a guaranteed positive output tolerance coupled with the bypass diodes, the neatly laminated cells perform excellent in both favorable and unfavorable conditions.

The build-quality cannot be better thanks to low-iron tempered glass, water-proof components, and a light frame. The weight is in acceptable limits for a polycrystalline panel. The panel is sufficiently durable and can sustain decent amounts of wind and snow loads. The dark aluminum frame makes the panel stand out from regular panels. If you are looking for long-lasting, well-built panels to power some or all of your home appliances, this is a suitable choice. Let us discuss the above in some more depth in this Renogy 270 Watt 24 Volt Polycrystalline Solar Panel Review.

Where To Buy


In several ways, the panel is promising in the compatibility aspect. For the mounting part, it is compatible with sloping as well as flat roofs. There are pre-drilled holes on the frame for mounting brackets as well as grounding wires. Two 32-inch cables coming out of the junction box have MC4 connectors on the ends, making series or parallel connections an easy affair. The panel has an open-circuit voltage of 38.60V, which means a series connection would be required for most inverters. The standard nature makes it compatible with all sorts and brands of inverters and junction boxes.


Solar panels, especially permanently mounted ones, are subjected to an array of weather types and loads for a few decades. This panel can be labelled adequately durable. It comes with a toughened glass and a light but robust frame that is also non-corrosive. The junction box and connectors are water-proof and prevent any short-circuit possibility in rainy conditions.

Ease Of Use

Being a non-portable panel, we do not expect much in the department of ease of use, but the features such as ample cable length and MC4 connectors make setting up the panel relatively easier. There is also less maintenance involved, thanks to superior quality components used in the making of it.


This 240W, 24V polycrystalline panel does not claim any truly unique feature like some of Renogy’s other products. This, however, does not make it an average solar panel. The makers have given due importance and attention to all the necessary basics. And therefore, though you may point out the lack of monocrystalline cells or an unconventional look, you cannot spot a serious flaw in what it does offer.


The panel is almost like any other solar panel in the market, except for the black-colored frame. The frame gives it a modern look, though it does not impact the performance in any way. The dark blue polycrystalline cell matrix lies in front and a white TPT back-sheet on the rear with a centrally placed black junction box.

What We Like

The Renogy 270-watt, 24-volt panel is a perfect example of a basic product done right. It does not try to innovate in large ways but it covers all the essential features and does it well. The water-proof and rust-proof components promise durability, and the positive output tolerance and bypass diodes promises above-average performance. To conclude, this is a practical and reliable solar panel to buy.


  • Excellent quality of components
  • Guaranteed positive output tolerance
  • Bypass diodes
  • Pre-drilled holes


  • Packing quality can be better
