The shift to renewable energy highlights the need for efficient hybrid solar-wind systems to reduce costs and emissions while ensuring sustainability. This study focuses on optimizing such systems for Barangay Graceville by considering weather patterns, energy use, and economic factors. By using local materials and cost-effective technologies, it aims to enhance affordability, accessibility, and long-term energy resilience. 

The researchers aim to answer the following questions: 

1. What designs and optimization are necessary for the Barangay, the study focuses on, in terms of:

1.1 Weather Behavior;

1.2 Energy Consumption; and

1.3 Economic Factors?

2. How can the hybrid systems be designed to meet the specific energy demands of the community, in terms of:

2.1 Community Needs; and

2.2 Scalable Designs?

3. How can the hybrid systems be designed to withstand environmental challenges in the community, in terms of:

3.1 Structural Durability Against Typhoons, Heavy Rainfall, and Floods; and 

3.2 Designing for Minimal Environmental Impact on Local Ecosystems?

4. What cost-effective design approaches can be applied to maximize affordability and accessibility in barangay Graceville, in terms of:

4.1 Locally Available Materials and Resources;

4.2 Integrate of Low-Cost Yet Efficient Technologies; and

4.3 Simplifying the Design for Easy Installation and Maintenance?

1. Barangay Graceville exhibits strong solar energy potential, receiving 5.1 kWh/m² per day, making solar power a viable option for renewable energy integration. However, the moderate wind speed of 2.5–4.5 m/s suggests that wind energy alone would be insufficient, making a hybrid solar-wind system the most practical solution. Additionally, the barangay faces frequent power outages during typhoons (40%) and transformer overloads during extreme heat (33.3%), indicating that the existing electrical infrastructure cannot support peak energy demands. In terms of the high energy consumption of government offices and businesses, coupled with monthly electricity costs ranging from ₱40,000 to ₱50,000, adds financial strain to the barangay. Moreover, 23.3% of households earn below ₱10,000 per month, limiting their ability to invest in renewable energy solutions. Addressing these economic disparities through government subsidies or community-based energy programs is crucial to ensuring equitable energy access for all residents.
   
   

2. The energy demand of Barangay Graceville is shaped by both residential and institutional consumption, with 50% of respondents expressing willingness to adopt renewable energy, while 43.33% are open to it if made affordable. However, 53.33% cite high installation costs as the primary barrier to adoption, followed by maintenance concerns (23.33%) and lack of information (16.67%). Additionally, farmlands and open spaces (43%) were identified as the preferred installation sites for solar-wind systems, followed by public buildings (27%) and households (27%). Given that only 46.67% are willing to invest less than ₱5,000, full-scale optimization is currently unfeasible, and a phased implementation strategy is necessary. A community-led approach, starting with pilot projects in public spaces, along with financial assistance and educational initiatives, would improve acceptance and readiness for a broader transition to renewable energy.
   
   

3. Environmental challenges, particularly typhoons, heavy rainfall, and floods, necessitate structural reinforcements for the hybrid solar-wind system. The study recommends tilted solar panels and reinforced wind turbine anchors to withstand typhoon winds exceeding 150 kph, while waterproof battery enclosures and corrosion-resistant materials protect the system during heavy rains. To mitigate flood risks, elevated solar panel structures and battery housing should be installed at least 1.5–2 meters above ground level. In terms of sustainability, rooftop solar installations and the use of lithium iron phosphate (LiFePO4) batteries can minimize land-use conflicts and reduce environmental toxicity. Additionally, placing wind turbines away from residential areas prevents noise pollution and ensures community acceptance. The adoption of recyclable and sustainable materials enhances long-term feasibility while addressing concerns about the environmental impact of renewable energy deployment.
   
   

4. Cost-effective strategies are essential for the successful implementation of a hybrid solar-wind energy system in Barangay Graceville. Using locally available materials such as solar panels and wind turbines from local manufacturers can reduce costs by 20–30%, making the system more affordable. Additionally, recycled aluminum and plastic composites for battery enclosures and panel frames further lower material expenses. The integration of hybrid inverters, which optimize energy distribution and reduce energy losses by 25%, enhances system efficiency. Battery management technologies, including smart charge/discharge controllers, extend battery life, ensuring long-term cost savings. A modular plug-and-play design allows for easy installation and maintenance, while vertical axis wind turbines (VAWTs) provide a low-maintenance alternative to traditional wind turbines. By simplifying design, integrating affordable technologies, and utilizing local resources, the hybrid system can be made more accessible and sustainable for residents and businesses alike.
