High-efficiency 180Wp TOPCon monofacial solar panel with half-cut cells, excellent weak-light performance, PID resistance, and long-term durability. Ideal for small rooftops, off-grid systems, and battery-based solar setups.
The Okaya 180Wp TOPCon Monofacial Solar Panel is designed for reliable power generation in compact and off-grid solar applications. Built with advanced TOPCon cell technology and a 36 half-cut cell configuration, this panel delivers high power density with improved efficiency and reduced energy losses.
Its PID-resistant construction, linear degradation profile, and minimal hot-spot risk ensure consistent performance over time. High-transmission advanced glass allows better light penetration, improving output even in weak or cloudy conditions. With controlled current flow and EL-tested output, the panel offers dependable performance across diverse environments.
Compatible with 12V battery-based off-grid inverters, SMUs, and solar charge controllers, this 180Wp panel is ideal for homes, shops, mobility solutions, and outdoor applications like RVs and camper vans.
Backed by a 5-year product warranty and 15-year performance warranty, it’s a compact, durable, and efficient solar solution for everyday energy needs.

With a 180Wp output on a 12V system, this panel is designed for compact off-grid applications such as battery charging systems, RVs, camper vans, cabins, outdoor lighting, and other small solar setups. It is ideal for charging a 12V battery bank efficiently but is not intended to power an entire home solar installation on its own.
Yes. The panel uses advanced TOPCon cell technology along with high-transmission solar glass, enabling excellent performance under low-light and overcast conditions. Compared with older panel technologies, it continues producing higher energy output even when sunlight intensity is reduced.
With a module efficiency of over 21%, the panel converts a greater percentage of sunlight into usable electricity than older polycrystalline panels. However, your actual daily energy generation depends on factors such as available sunlight, installation angle, seasonal weather conditions, and any shading on the panel—not the efficiency rating alone.
No. A solar panel should never be connected directly to a battery. A PWM or MPPT charge controller must be installed between the panel and the battery to regulate the charging current, prevent overcharging, and protect the battery. In many off-grid solar systems, this function is integrated into the solar PCU or inverter.
Yes. The panel is engineered for long-term outdoor durability. It features PID-resistant construction to minimize performance degradation, follows a linear degradation curve for predictable long-term output, and is designed to operate reliably in temperatures ranging from -40°C to +85°C, making it suitable for demanding weather conditions.
The panel includes two separate warranty protections. A 5-year product warranty covers manufacturing defects and workmanship issues, while a 15-year performance warranty guarantees that the panel will continue producing electricity at or above a specified minimum performance level over time. Together, these warranties provide both product reliability and long-term performance assurance.
