China's photovoltaic export model is undergoing a structural reset in 2026. The old playbook—shipping low-cost panels to every market under one spec—is dead. In its place, a country-by-country framework is taking hold, where N-type modules, solar-plus-storage bundles, carbon-footprint paperwork and

If you have solar panels on your roof—or plan to get them—you’ll likely hear contractors mention “grid connection points” and “tie-in points.” They sound similar, but they’re not the same. Mix them up, and you could end up with confusing electric bills or delays in getting paid for your surplus powe

As distributed photovoltaic (PV) capacity surges worldwide, engineers are shifting attention from panel layouts to the less visible but decisive layer: low-voltage electrical design. In a typical 380V grid-tied project, the system follows a “self-use first, surplus to grid”model, yet the real story

Rooftop solar is booming, but a photovoltaic (PV) module is not a passive slab—it is a live DC generator the moment light hits it. New safety pushes stress five non-negotiable field rules.First, kill the voltage before touching wires. Crews must lay an opaque cover (cloth, cardboard, dedicated shiel

Industry calculations show a rooftop PV system’s theoretical combined efficiency lands near 82% after stacking standard loss factors, but a wave of flat-laid arrays on color-steel warehouses and factory roofs has pulled actual performance ratio (PR) under 75% in recent installations. Three dominant

On concrete flat roofs, distributed rooftop solar arrays often use precast concrete ballast blocks instead of roof penetrations. These blocks resist wind through gravity: their dead weight creates a restoring moment against uplift and sliding forces acting on the modules and rails. Wind performance

Distributed rooftop PV is no longer just about mounting panels; safe and inspectable electrical work decides 20-year uptime. Based on 2026 residential and C&I field practice, eight rules stand out. PVC conduits must run straight and level, fixed with stainless clamps spaced within 1.5 m. Exposed cab

On flat concrete rooftops, site survey quality directly determines PV layout, annual yield, and O&M safety. Field measurement exposes shading risks that satellite maps and drawings often miss. Among all collected data, the heights of five vertical obstacles must be recorded one by one: parapet walls

As cities grow denser, rooftops are shifting from forgotten concrete planes to core nodes of urban energy systems.The so-called solar forest is not about planting trees. It is about arranging PV arrays so densely that they form an artificial green canopy over the city. They take no farmland, cut no
