Two panels, 200 watts total — 8% lighter and 11% smaller than comparable p-PERC panels, with next-generation N-Type cells that hold up better in heat and low light.
The Renogy 2-Piece 100 Watt 16BB N-Type Monocrystalline Solar Panel set (SKU: RSP100DCx2-US) gives you a ready-to-expand 200W solar foundation built around Renogy's latest N-Type TOPCon cell technology. Each rigid panel delivers up to 100W of output with a module efficiency rating of 20% and N-Type cell efficiency up to 25%, housed in a corrosion-resistant anodized aluminum alloy frame rated for the harshest rooftop and off-grid conditions. Compatible with 99% of MPPT and PWM charge controllers thanks to a sub-25V open-circuit voltage, these panels are the smart upgrade for RV rooftops, van builds, tiny homes, cabins, and any system where roof space is limited.
N-Type cells, a 16-busbar design, and a reinforced aluminum frame combine to make these panels a reliable, long-term performer across RV rooftops, off-grid cabins, and mobile power setups.
N-Type monocrystalline cells achieve up to 25% cell efficiency, delivering up to 20W more power than a comparably sized p-PERC panel — a meaningful gain when your roof space is fixed.
Sixteen busbars reduce internal electrical resistance and distribute mechanical stress across the cell, increasing power density while minimizing the risk of microcracks over years of vibration and thermal cycling.
A temperature coefficient of −0.29%/°C means these panels lose significantly less output on hot summer days compared to standard p-PERC panels — an important advantage for desert RVers and rooftop installs with minimal airflow.
With an open-circuit voltage of just 22.79V — well under 25V — these panels are compatible with the vast majority of MPPT and PWM charge controllers on the market, so you can drop them into your existing system without worrying about input voltage limits.
Each panel weighs just 13 lbs (5.9 kg) and is 11% smaller in footprint than an equivalent p-PERC 100W panel — making installation easier and leaving more roof real estate open for additional panels down the road.
An IP65-rated junction box and IP67-rated solar connectors keep moisture out in rain, humidity, and wash-downs. The aluminum alloy frame (over 1.1 mm thick) is engineered to handle snow loads up to 5,400 Pa and wind loads up to 2,400 Pa.
Each panel is constructed with low-iron tempered glass, a POE (polyolefin elastomer) encapsulant film, a TPT backsheet, and an anodized aluminum alloy frame over 1.1 mm thick — a noticeably heavier-gauge frame than many competing panels in this wattage range. The pre-drilled mounting holes on the back accept Renogy Z-brackets, corner mounts, and tilt mounts (all sold separately), making rooftop and ground-mount installations straightforward.

N-Type silicon has fewer impurities than p-type PERC silicon, which results in higher cell efficiency, a lower temperature coefficient (less output lost on hot days), better low-light performance, and a longer useful lifespan due to reduced light-induced degradation (LID). In practical terms, you get more usable energy per square foot over the life of the panel.
Both are accurate but measure different things. The 25% figure is the N-Type cell efficiency — how efficiently the solar cells themselves convert sunlight. The 20% figure is the module efficiency — the power output relative to the total panel area, including the frame and gaps. Module efficiency is always lower than cell efficiency because the frame takes up space that produces no power. Both numbers are verified from manufacturer and dealer sources.
Almost certainly yes. With an open-circuit voltage (Voc) of 22.79V, these panels are compatible with 99% of MPPT and PWM charge controllers on the market. Before connecting, verify that your controller's maximum PV input voltage exceeds 22.79V for a single panel (or a multiple of 22.79V if you plan to wire panels in series).
Yes to both. Wiring in series doubles the voltage (approximately 45.58V combined Voc) while keeping current the same — useful for longer wire runs or 24V systems. Wiring in parallel doubles the current while keeping voltage the same — useful for 12V systems or when your charge controller has a lower maximum input voltage. Always confirm your charge controller's maximum input voltage and current ratings before choosing a wiring configuration.
Each panel is optimized for use in 12V systems, with a maximum system voltage of 600V DC. This means you can connect multiple panels in series for higher-voltage (24V, 48V) systems as well, up to that 600V DC ceiling.
Mounting hardware is not included. The panels have pre-drilled holes on the back that are compatible with Renogy Z-brackets, corner mounts, and tilt mounts, all of which are available separately. If you are mounting these on a flat RV roof, Z-brackets are the most common choice. Tilt mounts can improve output on fixed installations by angling the panels toward the sun.
N-Type cells generally outperform p-PERC cells in low-light and overcast conditions, producing a higher percentage of their rated output when sunlight is diffuse. However, like all standard (non-bypass-diode-optimized) panels, output can drop significantly when part of the panel is shaded. If partial shading is a consistent issue for your installation, consider a panel with individual cell-level optimization or a microinverter setup.
For two panels wired in parallel into a 12V battery system, the combined short-circuit current (Isc) is approximately 10.62A. A 20A MPPT charge controller provides comfortable headroom. For a 24V battery system with the panels in series, a 10A MPPT controller is sufficient. Always size your controller to handle at least 25% more than the calculated maximum panel current to account for real-world conditions.
Real-world daily output depends on your location, season, panel orientation, and shading. As a general estimate, in an area with 4–5 peak sun hours per day, two 100W panels (200W total) can produce roughly 600–800 Wh (0.6–0.8 kWh) of usable energy per day after accounting for system losses. In high-sun areas with optimal tilt, output can be higher; in northern or overcast climates it will be lower.
Yes. The IP65-rated junction box and IP67-rated connectors seal out moisture in rain and wash-downs. The anodized aluminum alloy frame (over 1.1 mm thick) is rated for snow loads up to 5,400 Pa and wind loads up to 2,400 Pa, making these panels suitable for rooftop use in most North American climates, including areas with heavy snowfall.
The panels use industry-standard IP67-rated solar (MC4-compatible) connectors. Extension cables and adapter kits are not included and are sold separately. When purchasing cables, ensure they are rated for outdoor solar use and sized appropriately for your run length to minimize voltage drop.
Renogy provides a 10-year material and workmanship warranty and a 25-year output warranty. Because TrueStead Supply is an authorized Renogy dealer, the full manufacturer warranty applies to panels purchased here.
Yes. The RSP100DC panels are part of Renogy's wider N-Type solar panel ecosystem and can be connected in series or parallel with additional RSP100DC panels (or other panels with matching electrical characteristics). Be sure your charge controller's input voltage and current limits support your expanded array before adding more panels.
According to Renogy, the N-Type RSP100DC delivers up to 20W more power than a comparably sized p-PERC 100W panel, is approximately 8% lighter, and occupies about 11% less footprint — meaning you can fit more power in less space. The lower temperature coefficient (−0.29%/°C vs. typically −0.35%/°C or more for p-PERC) also means less power loss on hot days. The trade-off is a higher upfront cost per panel relative to older p-PERC options.
