This practical guide helps beginners avoid pitfalls in PV inverter selection. It highlights inverters’ core role as PV systems’ "energy heart" and focuses on three key aspects: power matching (0.8~1.1 ratio with solar panels), four inverter types (emphasizing 2025’s mainstream string and growing energy storage ones), and brand selection (scenario-based leading brands, three red lines, no blind pursuit of imports). It also provides a minimalist process, stressing "adaptation" over "high price" for long-term stability. Read More

This article focuses on the frequent severe weather such as heavy rainfall and thunderstorms during the flood season, which pose potential safety hazards to outdoor PV systems. It elaborates on the core protection measures for PV system waterproofing and lightning protection: waterproofing protection mainly targets key seepage-prone areas such as module connections, inverters, distribution boxes, lines and junction boxes, emphasizing adequate sealing, unobstructed drainage and timely inspections; lightning protection follows the principle of "all-round protection and graded current discharge", covering external interception, internal overvoltage suppression and grounding protection. In addition, it provides emergency response methods for potential hazards during the flood season, aiming to help household and industrial/commercial PV users safeguard power generation safety, avoid equipment damage and extend service life.

PV panel quality, critical to PV systems’ efficiency, service life and benefits, often misleads consumers via "low price" and "high power" gimmicks. This article, from a PV factory’s perspective, notes quality relies on raw materials, production processes and inspection, and offers practical tips to help consumers avoid pitfalls.​ With PV technology popularized, many are misled by "low price" and "high power" when buying PV panels (core of PV systems). From a PV factory’s view, we share quick tips to avoid pitfalls and choose quality panels.​ PV factories control quality from raw materials to finished products; their practical purchase tips, more authentic than distributors’, help avoid 90% of ineffective choices.

This article addresses common questions about whether household PV panels are afraid of sun exposure and rain. It points out that due to rigorous weather resistance tests before leaving the factory, as well as their sealed structure and high-quality materials, PV panels have excellent outdoor adaptability and are not afraid of sun exposure or rain, with a normal service life of 25-30 years. The article explains that sun exposure is the basis for their power generation, and only extreme high temperatures will slightly affect efficiency; rainwater can clean the panels, and water seepage can only be caused by improper installation or external damage. At the same time, PV panels can also cope with outdoor scenarios such as snow, hail and strong winds. They can operate stably for a long time with simple maintenance such as regular sealing checks and periodic cleaning. Read More

This article focuses on the concerns of household PV users regarding "whether PV subsidies will be cancelled" and "future income trends" after 2026. It clarifies that national universal PV subsidies have basically withdrawn, marking the industry's transition to market-oriented development, while targeted local subsidies still exist and tend to be precise and differentiated. The cancellation of subsidies is an inevitable trend of industrial maturity, as the reduction in PV equipment costs and the advancement of power market reform can offset the income gap caused by subsidy withdrawal. The article points out that after 2026, household PV income will show a steady growth trend, relying on three core pillars: saving electricity bills through self-consumption (the most stable income), earning electricity bills through surplus power grid connection (more flexible with market-oriented transactions), and additional value, remaining a stable family investment option.
