Renogy 200W 12V Monocrystalline Solar Panel: specs, loads and fit

The Renogy 200 Watt 12 Volt solar panel is a rigid monocrystalline module designed for RVs, boats, cabins and other off-grid battery systems. It is a single building block: you can use one panel, or wire several together for a larger array.

What 200 watts and 12 volts mean

The 200 W figure is the panel's output under standard test conditions. Real output depends on sun angle, temperature, shading and season, so it is usually lower. The "12 volt" label is the nominal system class, meaning the panel is intended for 12 V battery systems, normally through a charge controller that regulates power going into the battery.

Monocrystalline cells are cut from single-crystal silicon. They are generally more efficient than polycrystalline cells, which means more power from a given area.

Construction

Renogy says the panel uses multi-layered laminations and a TPT back sheet to protect the cells and give it a long service life. It is EL-tested, which is an imaging method used to look for cracks and defects in cells, and Renogy says this guards against hot-spot heating. Bypass diodes help limit power loss when part of the panel is shaded: instead of the whole panel dropping out, the shaded section is bypassed.

Wind and snow loads

Renogy lists a wind load of 2400 Pa and a snow load of 5400 Pa. These are standard mechanical test figures for panels, and they describe the pressure the panel is rated to withstand. The anti-reflective, low-iron tempered glass adds stiffness and impact resistance, and the corrosion-resistant aluminium frame is made for long outdoor use. The junction box is rated IP65, which covers protection against dust and low-pressure water jets.

The panel's output tolerance is guaranteed positive, at 0 to 3%, meaning a panel rated 200 W should not produce less than that under test conditions.

Mounting and compatibility

Pre-drilled holes on the back let you secure the panel quickly, and grounding holes are provided. Renogy says it works with its Z-Bracket, Pole Mount and Tilt Mount systems, and the listing mentions ground mounting. It is described as compatible with both on-grid and off-grid inverters. For electrical work, follow the manual and local codes, and consider a qualified installer for anything beyond a simple setup.

Size

The panel measures about 58.7 x 27.5 x 1.4 inches (roughly 149 x 70 x 3.6 cm). Check your roof or mounting area against that size, with room around the panel for airflow and for cables.

Warranty

Renogy lists a 10-year workmanship warranty and says the panel keeps over 80% of its output at 25 years. Read the warranty terms for the specifics.

Who it suits

It suits RV and marine owners with a 12 V battery, cabin owners building an off-grid system, and anyone adding capacity one panel at a time.

What to check before you buy

• Charge controller: a panel needs a controller matched to its voltage and current.
• Wiring: plan the series or parallel layout, cable gauge and fusing, and follow the manual.
• Roof space and weight: measure and check what the roof or mount can carry.
• Brackets and cables: mounting hardware and cabling aren't described as included, so check what you'll need.
• Shading: even small shadows reduce output, so choose the position carefully.
• Local rules: check codes that apply to your install.
