- Determined under standard test conditions (STC): Irradiance = 1000w/m² cell temperature = 25 °C; solar spectral irradiance per ASTM E892 (Air Mass = 1.5).
- Determined under nominal operating conditions (NOC): Irradiance = 800 w/m² ambient temperature = 20 °C; wind speed = 1m/s.
- Qualification Tests performed as per CEC 503 Test Specification, to ensure durability and performance in outdoor conditions.
- Diagonal lifting of module corner with three corners fixed.
- To original consumer purchaser. See full Limited Warranty for all conditions.
- * If the designer chooses to use the 6-volt version in a high voltage array configuration, the designer must install custom large bypass diodes and heat sinks around every 6-volt parallel string.
Siemens Solar SR100/SR90: High-Performance Modules for Off-Grid Excellence
Siemens Solar’s SR100 and SR90 modules are high-performance photovoltaic (PV) solutions delivering 100 watts and 90 watts, respectively, engineered for off-grid applications such as telecom stations, remote residences, and industrial systems. Part of Siemens Solar’s SR-series, these single crystalline modules offer outstanding power output, durability, and a 25-year warranty, making them a trusted choice for mission-critical energy needs. This article expands on the original SR100/SR90 page from our website, providing a detailed guide to their technology, specifications, installation options, benefits, and real-world applications, showcasing Siemens Solar’s expertise in delivering reliable off-grid power solutions.
The Rise of Off-Grid Solar Power
Off-grid solar systems have grown essential for remote energy access, with over 770 million people still unelectrified by 2023, per IEA data. The SR100 and SR90, introduced in Siemens Solar’s SR-series, were designed to meet these demands with silent, fuel-free operation and no waste, supporting applications where reliability is paramount.
“The SR100 and SR90 are off-grid champions,” says Dr. Maria Stein, Siemens Solar’s Off-Grid Lead. They deliver power where grids can’t reach.”
Why SR100/SR90?
- High Output: 90-100 watts per module for robust needs.
- Cost Savings: Saves $200-$400 yearly per kW versus diesel.
- Sustainability: Reduces emissions by 1-2 tons per kW annually.
- Reliability: 25-year power warranty.
Technology Overview
The SR100/SR90 feature 36 single crystalline cells, a rugged anodized aluminum frame, and EVA encapsulation, ensuring durability and efficiency.
Module Specifications
| Specification | SR100 | SR90 |
|---|---|---|
| Power Output | 100 watts | 90 watts |
| Efficiency | 15-16% | 14-15% |
| Size | 48” x 26” | 47” x 25” |
