Background analysis of household energy storage projects in Myanmar
一、 Project Background
As one of the countries in Southeast Asia with relatively backward power infrastructure, Myanmar has low coverage of the power grid in rural and suburban areas, and the existing power grid supply is extremely unstable, with frequent power outages being a serious problem. Many households rely on temporary lighting methods such as diesel generators or candles, which not only have high costs but also pose safety and environmental pollution issues.
With the advancement of photovoltaic and energy storage technologies, as well as the increasing demand for household electricity, the off grid/microgrid solution of "photovoltaic+energy storage" has become an important direction for Myanmar's household energy upgrade. This project is a 10kW (power)+40kWh (capacity) stacked energy storage system that provides stable, economical, and sustainable power supply for households in Myanmar.
二、 Current situation and challenges of hospital power supply
1. Insufficient power grid coverage and unstable power supply
The national electrification rate in Myanmar is about 50%, and it is even lower in rural areas. Many households have no electricity available or rely on unstable power grids.
The suburbs of cities also face the problem of 4-8 hours of power outages every day, which affects daily life and the use of household appliances. Realize seamless switching.
2. Diesel generators are highly dependent, but expensive in cost
The cost of diesel power generation is about 0.35-0.50 US dollars/kWh, much higher than the 0.15-0.25 US dollars/kWh of energy storage+photovoltaics.
Diesel engines have loud noise, serious pollution, and fuel supply is affected by international oil prices and transportation.
3. Abundant solar energy resources, but lacking energy storage facilities
Myanmar has an average annual sunshine of 2000-2500 hours, which is suitable for the development of household photovoltaics.
However, photovoltaic power generation has intermittency and cannot meet the electricity demand at night or on cloudy days without energy storage.
4. Growth in household electricity demand
With the popularization of household appliances such as television, refrigerator, washing machine, induction cooker, electric fan, air conditioner, etc., the electricity load of households has increased, and traditional small solar lights (such as 10W LED) can no longer meet the needs of daily high-quality life.
三、 10kW/40kWh Stackable Energy Storage Solution
1. System architecture
Photovoltaic power generation: 5-10kW rooftop photovoltaic array, with a daily power generation of 20-40kWh (under visual lighting conditions).
Energy storage system:
40kWh lithium iron phosphate battery, supporting modular stacking (such as 4 10kWh battery packs).
10kW pure off grid inverter, supporting photovoltaic+energy storage+diesel generator multi energy management.
Intelligent control automatically switches between photovoltaic/energy storage/grid/diesel engine, prioritizing photovoltaic energy. Mobile app for monitoring battery level and remote control.
2. Core functions
Function, technical implementation, user value
1.24-hour power supply, daytime photovoltaic charging, nighttime energy storage power supply, bidding farewell to power outages, ensuring continuous operation of refrigerators, air conditioners, etc., while reducing electricity costs, decreasing diesel engine usage, saving more than 50% of fuel costs, and lowering long-term usage costs.
2. Emergency backup power, automatic switching in case of power outage, seamless power supply, capable of responding to frequent power outages in Myanmar
3. Future expansion, supporting battery expansion (up to 80kWh+) to meet the growing demand for household electricity consumption
3. Economic analysis
Typical household electricity consumption: 10-20kWh per day (for lighting, TV, refrigerator, fan, etc.).
Investment cost: approximately 4000-8000 US dollars (including photovoltaic+energy storage+installation).
-Compared to diesel engines:
-The cost of diesel power generation is approximately 0.4 USD/kWh, and the annual electricity bill is approximately 1500-2000 USD.
-The lifespan of the energy storage system is 10 years, with an average annual cost of approximately $400-800 and a payback period of 2-3 years.
四、Project necessity analysis
1. Improving people's livelihoods: providing stable electricity and enhancing the quality of family life (such as night lighting, food refrigeration, and summer cooling).
2. Economically feasible: More cost-effective than diesel generators, with high long-term returns.
3. Environmental protection and carbon reduction: Reduce diesel pollution and help Myanmar's energy transition.
4. Scalability: In the future, it can be connected to microgrids or participate in community power sharing.
五、 Purpose
This project provides stable, economical, and sustainable power solutions for Myanmar households through a 10kW/40kWh stacked energy storage system, with significant social, economic, and environmental benefits. This model can be extended to regions with similar power shortages such as Southeast Asia and Africa, promoting the popularization of clean energy for households worldwide.
Next suggestion:
-Select pilot areas (such as suburban Yangon and rural Mandalay) for demonstration installation.
-Combining local distributors and financial institutions to lower the purchasing threshold for users.
-Monitor system operation data and optimize subsequent product design.
