Installing two separate solar systems with different meters for the first and second floor-- 3KW and 6KW respectively.
Specification
– Solar panel: 15 panels of 635W (high efficiency, large capacity)
– Inverter: Three Korean 3.5kW units
– Composition: 1st floor meter (3kW), 2nd floor meter (6kW)
Installation Analysis
– The installation type is a gable roof attachment, with modules placed optimally along the roof slope to maximize solar radiation. Structural stability is secured by using dedicated rails and fixing brackets. The slope and direction of the gable roof are ideal for local solar radiation conditions. Aadditionally, construction is conducted considering drainage and waterproofing.
Estimated power generation
– Solar radiation standard: Annual average approximately 1,200kWh/kW
– Total expected power generation:
9kW × 1,200kWh = 10,800kWh/year
– Average monthly power generation: Approximately 900kWh/month
Structure specifications
– Material: Aluminum alloy (corrosion resistant) Excellent)
– Fixing method: Bolt-nut fastening and waterproofing
– Size: Module 2465 × 1134mm, considering the entire roof area when arranging
Standard installation angle
– Optimal angle for average solar radiation: Approximately 30 degrees, slope has been adjusted to efficiently receive solar radiation according to seasonal changes in solar altitude
Installation Process
– The installation process begins with a preliminary site survey, followed by the design of meter separation to ensure accurate energy monitoring. Next, a thorough review and design of the roof structure are conducted to ensure stability and compatibility. This is followed by the installation of the solar modules and inverter. Afterward, electrical wiring and connection are completed to integrate the system. Finally, a comprehensive system inspection is carried out, concluding with the connection to Meralco for official grid integration.


This allows for efficient power management and greatly helps reduce household electricity bills.
Reduction of carbon emissions through use of eco-friendly energy
Energy independence for households[Examples of available electronic products]3kW equipment (1st floor): Refrigerator, washing machine, lighting, TV, air conditioner (small), etc.
6kW equipment (2nd floor): Large air conditioner, electric oven, electric rice cooker, vacuum cleaner, etc. High-power home appliances[Electricity bill savings]Based on 10,800kWh/year of power generation, monthly savings of approximately 6,480 peso to 7,400 peso are expected (based on average household usage)[Future of solar power]In the future, solar power is expected to continue to receive attention due to rising energy costs and carbon neutrality policies, and household and commercial installations will increase due to shorter installation cost recovery periods and improved efficiency.
