The battery pack is the core energy storage unit of photovoltaic power stations, whose operating status directly affects the stability, reliability and service life of the power station. Due to the complex operating environment and long-term charge-discharge cycle, the battery pack is prone to performance degradation and faults. This article combines the operating characteristics of battery packs in photovoltaic power stations and industry operation and maintenance standards, systematically elaborates on the key maintenance and management measures from six aspects: basic environmental and installation maintenance, daily and regular inspections, safety management, operation status control, fault handling and replacement specifications, and concludes with the importance of establishing a scientific maintenance system. It provides technical reference for the efficient, safe and long-term operation of battery packs in photovoltaic power stations. Read More

This article focuses on the daily inspection and maintenance of storage batteries (battery banks), adhering to the principle of "prevention first, combination of prevention and treatment". It elaborates on the core specifications and key points of environmental maintenance, safety protection, daily patrol inspection, operation parameter monitoring, maintenance taboos and special maintenance, aiming to ensure the reliable operation of storage batteries, extend their service life, and provide professional guidance for on-site maintenance work.

This article focuses on the reasonable design of PV arrays' tilt and azimuth angles in distributed PV power stations, emphasizing that their selection must combine building forms (reinforced concrete, steel structure color steel plate, etc.) and installation forms (fixed foundation, counterweight, etc.). It elaborates on tilt angle design points, azimuth angle principles, and core influencing factors, aiming to balance power generation efficiency and structural safety, and provide professional reference for engineering design.

The dream of true energy independence is more achievable today than ever before. Read More

Since early 2026, the Philippines has introduced strict renewable energy policies, including a 25GW new capacity target by 2035 and a mandatory 20% energy storage ratio for RE projects above 10MW. Plagued by a fragmented island grid, high fuel import dependence and climate pressures, the country is accelerating its energy transition, with PV+storage emerging as a core solution for grid stability. As a fast-expanding Southeast Asian market, the Philippines has drawn growing attention from global new energy firms, particularly Chinese companies, despite remaining challenges in auction mechanisms, grid connection and project execution.

In 2025, China’s residential PV installations grew strongly. The traditional rooftop leasing model offers farmers only low fixed rent with no property rights over the power station, resulting in meager long-term benefits. Tongyuan New Energy’s “10-Year Power Station Transfer” model allows farmers to join with zero cost, gain rent or free electricity in the first decade, and take full ownership of the station later. This model delivers much higher returns, provides reliable operation and maintenance, and turns farmers from landlords into shareholders, helping turn solar energy into stable income for rural revitalization.
