One of the most common questions homeowners ask before investing in renewable energy is: how long does a solar battery last at night? The simple answer is that a solar battery can typically power essential loads for 8 to 12 hours, but the actual duration depends on battery capacity, household energy consumption, battery type, and system design.

Solar photovoltaic systems are exposed to outdoor environments for a long time, and their safety, service life and economic benefits are directly affected by lightning, strong wind and corrosion. Based on relevant national standards and engineering practices, this paper systematically expounds the comprehensive protection schemes of photovoltaic panels from three aspects: lightning protection, wind resistance and corrosion prevention. It clarifies the technical points of direct lightning protection, surge protection, equipotential bonding, structural wind resistance design, anti-corrosion material selection and daily maintenance, so as to provide a reliable technical reference for the safe, stable and long-term operation of photovoltaic systems.

This article corrects the misconception in PV operation and maintenance that junction box overheating equals false soldering. Actual overheating mostly stems from increased contact resistance, faulty bypass diodes or cable issues, aggravated by high current. Heating patterns vary with string current and component quality, while infrared detection performance depends on distance and resolution. A simplified on-site troubleshooting method is also provided.
