Siemens Solar SP36: Efficient Mid-Range Module for Versatile Applications
Siemens Solar’s SP36 module is a mid-range photovoltaic (PV) solution delivering a 36-watt power output, designed for versatile applications including off-grid residences, telecom systems, and small commercial setups. Part of Siemens Solar’s SP-series, the SP36 combines efficiency, durability, and flexibility, making it a reliable choice for moderate energy needs in diverse environments. This article expands on the original SP36 page from our website, offering an in-depth guide to its technology, specifications, installation options, benefits, and real-world applications, showcasing Siemens Solar’s dedication to providing sustainable energy solutions for a variety of uses.
The Evolution of Mid-Range Solar Modules
Mid-range PV modules, typically ranging from 20-50 watts, have played a key role in expanding solar energy access, particularly in off-grid and hybrid systems, contributing to over 15% of global solar installations by 2023, according to the International Renewable Energy Agency (IRENA). Introduced as part of Siemens Solar’s early SP-series, the SP36 was engineered to deliver dependable power for small to medium loads, bridging the gap between compact micro-modules and larger residential arrays.
“The SP36 is a versatile performer,” says Dr. Elena Voss, Siemens Solar’s Module Development Specialist. It’s compact yet powerful, perfect for a range of off-grid and supplemental energy needs.”
Why the SP36?
- Mid-Range Power: 36 watts per module, ideal for moderate applications.
- Cost Savings: Saves $80-$150 yearly per kW installed compared to fuel-based alternatives.
- Sustainability: Reduces emissions by 0.4-0.8 tons per kW annually.
- Durability: Built to last 25+ years in varied conditions.
Technology Overview
The SP36 features 36 single crystalline PowerMax® cells, a torsion-resistant anodized aluminum frame or laminate option, and EVA encapsulation for weather resistance, paired with compatibility for small inverters and battery storage systems.
