In Philippines-2MW On Grid Solar System

The 2MW on-grid solar system in the Philippines is a highly efficient, stable, and cost-effective integrated energy solution specifically tailored to the Philippines’ tropical climate, power grid status, and growing energy demands. Using solar energy as its core energy source, the system adopts a grid-connected design to overcome the bottleneck of high traditional electricity costs and frequent power supply shortages in the local area, realizing the integrated operation of “solar power generation + grid connection + intelligent distribution.” It can meet the large-scale, continuous power needs of large industrial and commercial establishments, industrial parks, agricultural plantations, and public infrastructure in the Philippines, while simultaneously helping the Philippines reduce its dependence on fossil fuels, promote renewable energy development, and achieve national carbon emission reduction goals.

I. Core System Adaptability: Fitting the Philippines’ Regional and Energy Status Quo

The Philippines is located in a tropical maritime climate zone, with abundant sunshine resources throughout the year (average annual sunshine duration 2200-3000 hours, average daily solar intensity 4.5-6.5 kWh/m²), especially in the northern and central regions where solar potential is superior. However, the country also faces prominent problems such as insufficient power grid infrastructure, frequent power outages, high electricity prices (heavily dependent on imported fossil fuels), and a large energy supply gap. The 2MW on-grid solar system precisely addresses the aforementioned pain points: it fully utilizes the Philippines’ abundant solar resources for clean power generation, directly connects to the local power grid to realize “spontaneous self-use and surplus power grid connection,” which not only reduces the demand for grid power and lowers electricity costs, but also relies on the grid to balance the intermittency of solar power generation. It is perfectly suited to the Philippines’ energy environment, climate characteristics, and electricity needs.

II. System Core Configuration and Technical Parameters

The system adopts an integrated architecture of “photovoltaic modules + grid-tied inverters + combiner boxes + distribution cabinets + intelligent monitoring system.” All core components are selected from highly reliable products suitable for the Philippines’ tropical climate, high temperature, high humidity, and frequent typhoon weather, and comply with local electrical standards. The specific configuration is as follows:

Photovoltaic Modules (Core Power Generation Unit)

3226 sets of 620W high-efficiency monocrystalline silicon photovoltaic modules are used (total power approximately 2MW). The modules adopt anti-PID degradation technology and high-temperature resistance design, which can adapt to the Philippines’ high-temperature (30℃-40℃) and high-humidity environment, and have excellent weak-light power generation performance to cope with cloudy and rainy days in the rainy season. The surface is covered with high-transmittance, impact-resistant, and anti-reflective tempered glass, and the frame is made of high-strength corrosion-resistant aluminum alloy, which has good waterproof, dustproof, and typhoon-resistant performance. The service life is over 25 years, and the power generation attenuation rate is less than 12% in 25 years, reducing later maintenance costs.

Grid-Tied Inverters (Energy Conversion Core)

Equipped with 4 sets of 500kW centralized grid-tied inverters (or 8 sets of 250kW string inverters) that comply with Philippine grid connection standards. The inverters are mainly used to convert the DC power generated by photovoltaic modules into AC power that is synchronized with the grid’s frequency and voltage, with a conversion efficiency of up to 98% or more. They are equipped with advanced MPPT (Maximum Power Point Tracking) technology, which can real-time track the maximum power output of photovoltaic modules and improve the overall power generation efficiency. The inverters have a wide input voltage range, which can adapt to the characteristics of large voltage fluctuations in the Philippine power grid, and integrate multiple protection functions such as lightning protection, overvoltage, overcurrent, short circuit, and island protection to ensure stable and safe operation of the system and the power grid.

Combiner Boxes and Distribution Cabinets (Power Collection and Distribution Unit)

Equipped with 16-20 sets of photovoltaic combiner boxes, which collect the DC power generated by multiple groups of photovoltaic modules and transmit it to the inverters. The combiner boxes are equipped with anti-reverse connection, lightning protection, and overcurrent protection functions, which facilitate group management and fault diagnosis of photovoltaic modules. The distribution cabinets adopt IP54 protection level design, suitable for outdoor installation in the tropical climate of the Philippines. They integrate main switches, energy meters, protection relays, and other equipment, which are responsible for distributing the AC power output by the inverters to meet the local load demand, and stably connecting the surplus power to the grid. The energy meters comply with Philippine electricity metering standards, which can accurately count power generation, power consumption, and grid-connected power, providing reliable data support for electricity fee settlement and benefit calculation.

Intelligent Monitoring System (Operation and Maintenance Core)

Equipped with an industrial-grade intelligent monitoring system, supporting local touch-screen monitoring and remote monitoring via mobile APP and computer client. The system can real-time collect key data such as photovoltaic module power generation, inverter operation status, grid parameters, and equipment temperature, and generate visual reports and curves. It has automatic fault diagnosis and hierarchical alarm functions, which can push equipment fault information (such as module shading, inverter abnormality, grid power failure, etc.) in the first time to facilitate maintenance personnel to respond quickly. It also supports functions such as power generation data statistics, benefit calculation, and maintenance record management, realizing full-life-cycle intelligent management of the system.

Auxiliary Equipment

Includes photovoltaic mounting systems, lightning protection and grounding systems, special photovoltaic cables, and cable trays. The photovoltaic mounting systems adopt hot-dip galvanized steel structures, supporting rooftop distributed installation and ground centralized installation. Rooftop installation does not occupy additional land resources, which is suitable for factory workshops and commercial building rooftops; ground installation adopts a fixed-angle design adapted to the Philippines’ latitude to maximize solar energy reception, and the bracket structure is designed to resist typhoons (wind resistance level ≥13), which can withstand the impact of local frequent typhoons. The lightning protection and grounding system strictly complies with Philippine grid lightning protection standards to effectively avoid equipment damage caused by thunderstorms. The cables are special photovoltaic cables with high and low temperature resistance and anti-aging performance to ensure safe and stable power transmission.

III. Typical Application Scenarios

Large industrial and commercial establishments: Such as manufacturing factories, large shopping malls, high-end hotels, and logistics parks. These scenarios have large and stable power loads, with a high proportion of “spontaneous self-use,” which can significantly reduce electricity costs, avoid production interruptions and business losses caused by grid power outages, and improve operational profitability.

Industrial parks and economic development zones: As a distributed energy project in the park, the 2MW on-grid solar system can centrally supply power to multiple enterprises in the park, realize centralized energy supply and unified management, improve the park’s energy utilization efficiency, reduce the overall electricity cost of the park, and help build a green and low-carbon industrial park.

Large-scale agricultural plantations: The Philippines has abundant agricultural resources. Large-scale plantations, aquaculture bases, and agricultural product processing parks have large power demands for irrigation equipment, breeding equipment, and processing machinery. The system can meet their outdoor and indoor power needs, replace traditional high-cost grid power or diesel power generation, and reduce agricultural production energy costs.

Public infrastructure: Such as large hospitals, universities, government office buildings, and municipal facilities. It can ensure the continuous power supply of medical equipment, teaching equipment, office equipment, and municipal operation equipment, reduce the energy expenditure of public services, and practice the concept of green public services.

IV. System Installation and Maintenance

For installation, rooftop or ground installation can be chosen according to site conditions and local land use regulations: rooftop installation adopts a distributed layout, which does not occupy additional land resources and is suitable for urban industrial and commercial buildings; ground installation adopts a centralized layout, which is suitable for areas with sufficient land such as plantations and industrial parks. The installation process strictly complies with Philippine construction and electrical safety standards, and the installation cycle is about 45-60 days. A professional team can provide one-stop services from on-site survey, customized design, environmental assessment, construction, commissioning to grid connection (including handling local grid connection approval procedures).

For maintenance, the system has a high degree of intelligence and low maintenance difficulty. It is necessary to regularly clean the dust, dirt and bird droppings on the photovoltaic modules (especially in the rainy season and typhoon season); check the operation status of inverters, combiner boxes and other equipment monthly; conduct a comprehensive inspection and maintenance every six months, including bracket tightness, wiring status, lightning protection system and grounding performance. The core components have long quality assurance periods, and local professional maintenance teams can provide timely after-sales services to ensure long-term stable operation of the system.
