In order to evaluate the financial feasibility of integrating energy storage systems with solar PV system in detached houses, economic indicators able to compare the costs of the different storage scenarios with one another are needed.
While the costs of all energy storage systems remain too high to be considered financially attractive without further support mechanisms, LIB storage is clearly the best storage alternative in all scenarios with a LCC 1000–7500 € higher and a LCOE 0.005–0.04 €/kWh higher than the costs of a 13.5 kW stand-alone solar PV system.
Hence, the optimal capacity of all the energy storage systems is zero, whereas the feasible solar PV size is limited to below 20 % when using the 2019 electricity prices as comparison.
For the battery storage system, a 90 % round-trip efficiency was used, representing the use of a generic LIB , . For the H 2 energy storage system, a 30 % round-trip efficiency was used, a value that could also be lower for small-scale energy storage applications.
Solar PV systems without selling surplus electricity to the grid were profitable up to a renewable fraction of 10 % with 2019 market prices and up to 35 % with the 2021 unusually high market prices.
While LIB storage clearly remains the most feasible energy storage technology with a LCOS of 3–5 times higher than the LCOE of grid electricity, the LCOS of the discharged energy from the H 2 storage and TES system is between 5 and 20 times higher than that of grid electricity.

Sephu plant will serve as an addition to the 180 kW grid-connected ground-mounted solar photovoltaic power station in Rubesa (near ), which became operational in October 2021. The Sephu plant is currently under construction over an area of 65 acres in Yongtru village, situated in the . Upon its completion, the overall installed capacity of the facility will reach 22.38 megawatts and is expected to be complete by March 2025. It was initially planned a. [pdf]
The Chairperson of the National Council of Bhutan, Lyonpo Tashi Dorji, inaugurated the 180kW grid-tied ground mounted Solar Photo-Voltaic Power Plant at Rubesa, Wangdue Phodrang on October 4, 2021.
The commissioning and inauguration of the 180kW grid-tied ground mounted solar photo-voltaic power plant marks the start of Bhutan’s investment in grid-tied solar energy as a viable alternative energy source in the face of soaring domestic demand and climate change.
Minister of Energy and Natural Resources, Loknath Sharma said, “Sephu solar plant is the first medium solar farm in the country.” The minister said that Sephu solar plant marked the beginning of achieving a 500-megawatt energy target through solar power in the next three years. He said that the plant project is undertaken by the ministry.
When Shingkhar solar power plant was dropped the ADB couldn’t fund the wind farm as it became economically non-viable. As per the Renewable Energy Management Master Plan 2016, it is estimated that Bhutan has the potential to produce 12 gigawatts of solar and 760 megawatts of wind energy.

Large scale renewable projects are becoming a point of interest for investment in Mozambique, specifically solar and hydro. Mozambique’s main body to promote renewable energy access, FUNAE, expects that the capacity of on-grid renewable energy from independent power producers (IPP) will increase to 575. . Mozambique has an abundant and unexploited solar resource which could be harnessed for utility scale as well as residential PV for both on/off grid electrification. The. . As of 2020, Mozambique has one of the highest hydropower potential in Africa, estimated at more than 12,000 MW, especially in the Tete province, at the Zambezi River, where the. .

The PV power potential map developed by the World Bank shows the potential for PV power projects in Mozambique on a scale of a yearly total specific PV power output of 1,534 to 1,753 kWh/kWp. The zones marked in the darkest shade show the highest potential .
In a new monthly column for <b>pv magazine</b>, SolarPower Europe describes how Mozambique may take full advantage of its huge solar potential by implementing its recently launched Renewable Energy Auctions Programme for large-scale projects, while also pushing for more off-grid renewables in remote areas.
The zones marked in the darkest shade show the highest potential . By the end of 2022, there is a total of 125 MW of solar power plants (under a public-private partnership (PPP)) developed in Mozambique, of which 60 MW are already connected to the national grid: Projects Mocuba and Metoro.
Future tenders are expected to be announced in Q4 of 2023, including the selection of two independent power producers for two 30 MW solar photovoltaic power plants and one 50 MW wind power plant. But Mozambique has an enormous challenge that spreads far beyond where the national grid ends.
