Mobile sun: portable panels for self-generated power supply
Alternative Energy Projects (AEP) developed a portable solar power plant Solar Box, which is a 12.5 tons container holding 168 generation modules 560 Watt each. The aggregated capacity of the unit in its standard configuration makes 94 KW, which is sufficient for supplying energy to ten cottages.

In addition to solar generation modules, the standard configuration with EUR 125 thou cost includes an inverter (the device converting the direct current into alternate current), an AD marshalling box and an energy storage unit. The installation, i.e., placing the panels on a solid surface at an angle of 15 degrees, will take 30-45 minutes. The portable power plant may be used not only for self-generation of energy, but may be connected with a low-voltage or medium-voltage system. The advantages of this novelty also include the easiness of transportation and the scalability: the customised configuration for industrial users its total capacity may achieve 5 MW, allowing for using it to supply energy to big construction sites and manufacturing sites.

The possibility of using the portable power plant for supplying energy to industrial site may facilitate its commercial distribution in the countries having energy shortage. Ethiopia is an example, where 24 industrial parks are operating, each of them consisting of hangars with the footage of 6 thou and 11 thou square metres. “Just give me the chance to install solar panels on the roofs of those hangars, and I will provide for energy generation in the volumes exceeding the needs of the industrial parks”, Mikael Alemu, the co-founder and CEO of 10 Green Gigawatt for Ethiopia, stated at the conference “Regional to Global: Africa” organised by the Global Energy Association in February 2023.

Mobile solar units may be of demand to supply energy to remote territories. Rosseti company is using the combined solar and diesel generating units for these purposes: diesel generators cover the demand for electricity during the peak hours in the mornings and in the evenings, and photovoltaic panels – during the daytime accumulating excessive energy in the batteries, which provide electricity during the nighttime.

Gas-fired power plants account for 60% of Africa’s generating capacity growth

The capacity of all types of power plants in Africa grew by 145 GW between 2000 and 2021, which is comparable to the capacity of the available wind generators in the United States (141 GW). According to the Ember research centre estimates, gas-fired thermal power plants (TPPs) provided 60% of the growth, coal-fired TPPs, fuel oil and diesel generators – 17%, whereas all renewable sources (RES) accounted for 23%.

Distributed generation capacity in Brazil exceeded that of gas-fired power plants

The number of distributed generation systems in Brazil reached 1.8 million units in the first quarter of 2023; their total capacity is 19 GW, which exceeds the capacity of all gas-fired power plants operating in the country (14.5 GW). Such data are provided by the Energy Information Administration (EIA) of the US Department of Energy with reference to the Brazilian Electricity Regulatory Agency (Agência Nacional de Energia Elétrica, ANEEL).
