Zambia’s Solar Boom: The Best Inverters for Reliable Power!

1.Zambia’s Power Structure

Zambia’s power generation structure is primarily based on hydropower, supplemented by other forms of energy generation. With abundant water resources, hydropower is the country’s main source of electricity, accounting for approximately 80% of Zambia’s total power generation. According to data provided by CEIC, Zambia’s total electricity generation in 2022 was 19,399 GWh, which slightly decreased to 19,373 GWh in 2023. The country’s heavy reliance on hydropower makes it vulnerable to extreme weather conditions, especially during dry seasons when insufficient rainfall leads to lower water levels in hydropower stations, significantly affecting electricity supply.

2.Severe Power Shortage in Zambia

Zambia is currently facing a severe power shortage. As of the latest update on August 15, 2024, the water levels in the reservoir of Zambia’s largest hydropower station have been continuously declining, leaving only about 10% of usable water for power generation. As a result, the power deficit is expected to increase by 300 MW.

Zambia’s total installed capacity stands at 3,777 MW, while the country’s average peak electricity demand remains at 2,400 MW. However, the available power generation capacity averages only 890 MW, leading to a power shortfall of 1,510 MW. Zambia’s national power utility, along with other power traders, is importing 496 MW of electricity from the Southern African region, but the total power shortage still exceeds 1,000 MW.

Due to insufficient rainfall during the 2023-2024 rainy season, which caused a decline in reservoir water levels, Zambia’s power utility announced an 8-hour daily load-shedding schedule in March 2024. This schedule was gradually extended, and starting from September 1, the daily power cuts will increase from 14 hours to 17 hours. In response to the ongoing power crisis, the Zambia government is encouraging investment in alternative energy sources, particularly solar energy.

3.Rising Electricity Prices in Zambia

Zambia’s electricity prices have traditionally been relatively low. However, due to recent drought conditions affecting hydropower generation, the Zambia Electricity Supply Corporation (ZESCO) has adjusted its electricity pricing structure. According to a report from Zambia

media on August 18, 2024, ZESCO has expanded its existing pricing tiers and introduced different adjustment plans for residential and commercial electricity users.

For residential electricity consumers:

The electricity price for the first 100 kWh (lifeline tariff) will remain unchanged.
The proposed tariff increase will range from 50% to 156%, affecting approximately 44% of Zambia households (417,365 households).
The tariff for the first and second consumption tiers will remain unchanged to prevent additional financial burdens on low-income households.

For commercial electricity consumers:

For electricity usage below 500 kWh, the price will remain unchanged.
For electricity consumption above 500 kWh, tariffs will increase, with a proposed adjustment of approximately 39%.
For low-income families, the lifeline tariff remaining unchanged ensures that their electricity costs will not increase. However, for households consuming beyond this limit, electricity expenses may rise significantly.

The increase in electricity prices will also raise operational costs for businesses in Zambia, especially for industries with high electricity consumption, potentially impacting their operations. However, on the other hand, rising electricity prices and power shortages may accelerate the growth of Zambia’s solar energy market. These factors are expected to drive the development of residential solar photovoltaic (PV) projects and increase demand for solar-related products such as solar inverters, solar power generation systems, and solar PV panels.

Recommended Solar Storage Capacity for Zambia Homes

Based on household power consumption, the following storage capacities are recommended:

• Small Households (1-3 people)
  – Daily consumption: 5kWh – 7kWh
  – Recommended storage: 5kWh – 10kWh
• Medium Households (4-6 people)
  – Daily consumption: 8kWh – 12kWh
  – Recommended storage: 10kWh – 15kWh
• Large Households (6+ people)
  – Daily consumption: 12kWh – 20kWh
  – Recommended storage: 15kWh – 20kWh+ (expandable modules)

Off-grid solar power generation system suitable for Zambia

Zambia has a total population of 20.72 million (2023). Currently, the electricity coverage rate among the Zambia population is 25%, while the electricity coverage level in rural areas is less than 5%. Electricity is the foundation of industrial development. Without reliable power supply, there can be no stable industrial production and economic development. Electricity is related to the daily life of the people. If there is a long power outage every day, the quality of life of the local people will inevitably decline significantly. In the current situation of energy shortage in Zambia, how to effectively improve the problem of electricity consumption? Then the solar power generation system is a good solution, and the off-grid solar power generation system is a solar energy solution that is very suitable for many families and businesses in Zambia.

Solar power generation systems are divided into off-grid solar power generation systems, grid-connected solar power generation systems, and hybrid solar power generation systems.

The off-grid solar power generation system is an independent power generation system that does not rely on the public power grid. It can independently supply power to households or small communities, solving the problem of lack of power grid coverage. The system uses solar panels to convert solar energy into electrical energy and store electrical energy for use at night. When using household appliances, the DC power generated by solar panels or stored in batteries is converted into AC power by solar inverters for use by equipment loads.

Off-grid solar power generation systems require energy storage batteries. The biggest advantage is that they can generate electricity independently and will not be affected by grid failures or power outages. This makes off-grid solar power generation systems very practical in remote areas or places where there is a lack of grid coverage, such as rural areas or mountainous areas. For people in Zambia who often suffer from power outages, off-grid solar power generation systems are a rigid and very suitable choice, especially in a country with abundant solar energy. It can bring stable and reliable electricity to Zambians, improve electricity conditions, and improve the quality of life without worrying about power outages.

Grid-connected solar power generation systems are a system that converts the DC power generated by solar panels into AC power that meets the requirements of the grid through a grid-connected inverter and then connects to the public grid to achieve power sharing and allocation. This system can sell electricity to grid companies and obtain electricity from the grid when needed. The biggest advantage of the grid-connected solar power generation system is that it can interact with the power grid and there is the possibility of power complementarity. The grid-connected solar power generation system does not require additional energy storage equipment. It is suitable for cities and industrial areas with good grid coverage and large power demand. It is suitable for large-scale national photovoltaic power generation projects, but not suitable for Zambian households. The grid-connected system needs to be connected to the public power grid to operate. In the case of a power outage, the system will stop working and cannot provide electricity to the family. The grid connection depends on sunlight, and the grid-connected type is usually not equipped with batteries. Once the power outage, the system cannot supply power, and it cannot be used on cloudy days or at night.

The hybrid solar power generation system combines the advantages of the off-grid system and the grid-connected system. It can sell excess electricity to the power company, and when the power grid is out of power, it can provide electricity to the family through the photovoltaic energy storage battery. The grid and solar energy can charge the battery at the same time. It is highly flexible and can achieve the purpose of self-generation and self-use, and the purpose of surplus electricity to the grid, so as to maximize the utilization of photovoltaic power generation and improve the efficiency of photovoltaic energy utilization.
