Model S-245-60-1 | Polycrystalline Silicon | 60 Full-Cell Polycrystalline | Monofacial | 1000V System Voltage
The Solar Power Technology S-245-60-1 245W polycrystalline solar panel is designed for reliable energy production in residential and commercial systems. This SPOT S-245-60-1 module uses high quality 60 cell polycrystalline silicon technology for stable performance in a wide range of climates. With a rated maximum power of 245 watts and panel efficiency of 15.06 percent, it helps rooftops and ground mount arrays use available space efficiently. The robust anodized aluminum frame and tempered glass provide strength in tough outdoor conditions. A maximum system voltage of 1000 volts supports flexible string design for grid tied or stand alone setups. The panel is engineered for durability, with EVA encapsulation and a weather resistant junction box that protect the cells from moisture and UV exposure. Manufactured by Solar Power Technology Co., Ltd. in Thailand, the S-245-60-1 panel offers dependable performance for long term solar investments. Its balanced electrical characteristics simplify system design, while the moderate weight supports straightforward handling during installation. This module suits village power, solar home systems, telecommunications backup, lighting, and many other off grid or grid connected applications.
Balanced 245W power rating: A maximum power output of 245 watts offers an effective balance between size and production. It supports efficient string layouts for homes, businesses, and small commercial arrays.
Proven polycrystalline cell technology: High efficiency polycrystalline cells deliver consistent performance under real world operating conditions. The 60 cell layout follows a widely used industry format that simplifies design and replacement.
Durable construction for long life: Tempered low iron glass, EVA encapsulant, and a composite backsheet protect cells from humidity and mechanical stress. The anodized aluminum frame offers corrosion resistance in coastal and high humidity environments.
Flexible system integration: A 1000 volt maximum system voltage allows longer strings and lower balance of system costs. The 20 amp series fuse rating fits a wide range of inverters and charge controllers for grid tied and off grid systems.
Reliable performance in varying temperatures: Optimized temperature coefficients limit power losses as cell temperatures rise. Stable output over hot afternoons and cooler mornings supports predictable energy yields across the year.
Suitable for many applications: The module has been tested for grid connected and stand alone systems, including village power, security lighting, electric fencing, and telecommunications. Installers can use one product family across multiple project types.
The SPOT S-245-60-1 solar panel converts sunlight into usable DC electricity through high efficiency polycrystalline silicon cells. When sunlight strikes the 60 cell matrix, photons are absorbed and create an electric field across each cell. This effect causes electrons to flow, generating direct current that is collected by the panel’s busbars and output cables. The tempered glass and EVA encapsulation protect the cells while still allowing strong light transmission. A weather resistant junction box with built in bypass diodes manages current flow and helps maintain energy production under partial shading. The panel can feed a grid tied inverter, a charge controller, or a hybrid system that includes battery storage. By wiring multiple S-245-60-1 modules in series or parallel, system designers can reach the desired array voltage and current. Once connected to the broader system, the panel operates quietly and automatically whenever sufficient sunlight is available.
Light capture and DC generation: Low iron tempered glass allows high solar transmittance to the polycrystalline cells. These cells convert incoming light into direct current through the photovoltaic effect, delivering up to 245 watts at standard test conditions.
Cell protection and electrical isolation: Sheets of EVA encapsulant and a durable composite backsheet surround the cell strings. This structure seals out moisture, provides UV stability, and offers electrical insulation up to 1000 volts for safe operation over time.
Power management and system connection: The rear junction box houses three bypass diodes that help reduce power loss when some cells are shaded. From the junction box, 4 mm² solar cables carry the DC output to inverters, charge controllers, or batteries as part of the overall system.
