🌞 How to Calculate the ROI of a Solar Power Plant? 🌞 Investing in solar power is not only good for the environment but can also be a highly rewarding financial decision. Here's a step-by-step guide to determine the Return on Investment (ROI) for your solar project: 1️⃣ Understand the Costs 🔹 Capital Costs: Equipment (panels, inverters), installation, and permits. 🔹 O&M Costs: Annual expenses for maintenance, insurance, and repairs. 2️⃣ Estimate Annual Revenue or Savings 🔹 For Self-Use: Savings from reduced electricity bills. 🔹 For Commercial Projects: Income from selling electricity (PPA or tariffs). 💡 Formula: Annual Revenue (₹) = Energy Produced (kWh) × Electricity Rate (₹/kWh) 3️⃣ Factor in Degradation Solar panels lose efficiency over time (typically 0.5%-1% per year). Adjust your revenue estimates accordingly: Adjusted Revenue (Year t) = Annual Revenue × (1 - Degradation Rate)^(t-1) 4️⃣ Calculate Lifetime Benefits Add up the revenues over the plant’s life (usually 25 years), minus costs. Don’t forget subsidies or incentives! 5️⃣ ROI Formula ROI (%) = [(Lifetime Benefits - Capital Costs) / Capital Costs] × 100 6️⃣ Payback Period Determine how long it takes to recover your initial investment: Payback Period (years) = Capital Costs / Net Annual Revenue Example For a plant costing ₹50,00,000, generating 100,000 kWh annually at ₹6/kWh: ✅ Payback Period: ~9 years ✅ ROI: ~150% over 25 years 💡Let’s harness the power of the sun for a sustainable and profitable future! 🌍☀️ #SolarEnergy #RenewableEnergy #SolarROI #Sustainability #CleanEnergy #GreenInvestments

Alhamdulillah satu jurnal lagi terbit : Energy Performance and Financial Assessment of a Rooftop Photovoltaic System for the Physics Laboratory at Universitas Negeri Jakarta Abstract: The integration of renewable energy within educational institutions plays a strategic role in promoting sustainable development goals. This study provides a comprehensive techno-economic assessment of a 5.46 kWp rooftop photovoltaic (PV) system designed for a physics instrumentation laboratory at Universitas Negeri Jakarta, Indonesia. The study aims to evaluate the system’s capability in meeting the laboratory’s specific electricity demand of 20.616 kWh/day (7.422 MWh/year) while analyzing its financial feasibility under Indonesia’s subsidized electricity tariff structure. Using PVSyst software and meteorological data, a system comprising 12 monocrystalline modules (455 Wp each) and a 5 kW off-grid inverter was simulated. Results indicate an annual energy production of 7.876 MWh, with an excellent specific yield of 1,443 kWh/kWp/year and a Performance Ratio (PR) of 71.42%. The PV system demonstrates the ability to supply nearly all of the laboratory’s annual energy needs and reduce approximately 6.0 tons of CO₂ emissions per year. Financial analysis, however, reveals significant constraints: Levelized Cost of Electricity (LCOE): IDR 1,468/kWh Payback period: 17 years Return on Investment (ROI): 9.1% over 20 years The findings conclude that, while technically feasible and environmentally beneficial, the economic attractiveness of such PV systems is heavily limited by subsidized electricity tariffs for educational institutions in Indonesia. ------- We are pleased to let you know that the final version of record of your article has now been published to IOPscience and can be found online at https://lnkd.in/gZ8Ba4pQ.
