Takeaways

• 😀 **Project Setup**: Start by naming the project and providing a description, then select the location using Google Maps to get the exact coordinates for installation.
• 😀 **Using HOMER Pro**: Enter geographic coordinates and resource data (solar radiation, wind speed, temperature) into HOMER Pro to optimize the energy system design.
• 😀 **Energy Load Profile**: Define load profiles based on residential, commercial, or industrial needs, with specific peak demand times (e.g., 6:00 PM to 9:00 PM for residential).
• 😀 **System Sizing**: Choose the appropriate size for the solar power system (e.g., a 3 kW PLTS system) to meet energy demand and ensure efficient operation.
• 😀 **Cost Breakdown**: Calculate costs for different components, including solar panels (47%), inverters (13%), and installation/miscellaneous costs (40%).
• 😀 **Initial Investment Calculation**: The total cost of the system is calculated based on the component costs, with a 3 kW system estimated at **Rp 35,250,000** for solar panels and **Rp 9,750,000** for the inverter.
• 😀 **Grid Interaction**: In this simulation, the system is designed without selling power back to the grid, as indicated by setting the grid sell-back price to zero.
• 😀 **Emission Reduction**: The PLTS system reduces carbon emissions, with a calculated reduction of **3 kg of CO2 per year**.
• 😀 **Economic Analysis**: Include key economic factors like the discount rate (5.98%), inflation rate (4.04%), and the project lifetime (25 years) to assess long-term viability.
• 😀 **Simulation Results**: The system reduces the levelized cost of energy (LCOE) from **Rp 1,444/kWh** to **Rp 1,199/kWh** and achieves **50.2% renewable energy penetration**.
• 😀 **Report Generation**: A detailed engineer's report is generated, summarizing the technical, economic, and environmental results of the system simulation, available in PDF format.

Q & A

What is the main focus of the practical exercise described in the transcript?

The main focus of the practical exercise is to design and simulate a solar power system (PLTS) using Homer Pro software, with an emphasis on renewable energy systems.

How is the location for the solar panel installation determined in the simulation?

The location is determined using Google Maps. The coordinates of the desired location, in this case, Universitas Jenderal Ahmad Jani in Indonesia, are input into the Homer Pro software.

What environmental data is needed to optimize the solar system design in Homer Pro?

The environmental data required includes solar radiation, wind data, and temperature. These are selected within the Homer Pro software to optimize the solar power system design.

What is the role of load types in the simulation, and how are they defined?

Load types define the power consumption patterns of the system. In the simulation, the load types are categorized into residential, commercial, and industrial, each with specific peak power usage times, like evening for residential and daytime for commercial loads.

How is the capacity of the solar panels (PLTS) determined in the simulation?

The capacity of the solar panels is calculated using formulas provided in the practical module. In the example, the solar panel capacity is determined to be 3,000 watts (3 kW).

What is the cost breakdown for the solar panel system, and how is it calculated?

The total cost for the solar system is broken down into 47% for solar panels, 13% for inverters, and 40% for other costs like installation and cables. The cost per kW is calculated based on market prices, with the total for 3 kW reaching Rp 35,250,000.

How does the inverter's cost and replacement affect the simulation?

The inverter's cost is calculated based on the price per kW, and its replacement is scheduled every 10 years. The replacement cost is equal to the initial purchase price of the inverter, which in this case is Rp 9,750,000.

What role does the 'grid power' setting play in the simulation?

The 'grid power' setting determines the relationship with the electricity grid. In this case, the simulation assumes that no electricity is sold back to the grid, and the price for grid electricity is set to zero.

How are emission reductions from the solar power system calculated?

Emission reductions are calculated based on the reduction of CO2 emissions from using a solar power system instead of a coal-based power plant (PLTU). The reduction is estimated at approximately 3 kg of CO2 per year.

What economic parameters are configured in the Homer Pro simulation?

The economic parameters include the discount rate (5.98%), inflation rate (4.04%), and project lifetime (25 years). These parameters are used to calculate the overall economic viability of the solar power system.
