SMA had 4,377 employees and generated worldwide sales of 1,904.1 million euros and an EBITDA of 311 million euros in 2023. [1] It is the largest Europe-based solar technology company by revenue. [2] The company is focused on the development and manufacture of system technology for photovoltaics, battery storage systems and energy management ...
Cut-away schematic diagram of a sodium–sulfur battery. A sodium–sulfur (NaS) battery is a type of molten-salt battery that uses liquid sodium and liquid sulfur electrodes. [1] [2] This type of battery has a similar energy density to lithium-ion batteries, [3] and is fabricated from inexpensive and low-toxicity materials.
Sodium sulfate (also known as sodium sulphate or sulfate of soda) is the inorganic compound with formula Na 2 SO 4 as well as several related hydrates.All forms are white solids that are highly soluble in water.

Sodium sulfide is a chemical compound with the formula Na 2 S, or more commonly its hydrate Na 2 S·9H 2 O.Both the anhydrous and the hydrated salts in pure crystalline form are colorless solids, although technical grades of sodium sulfide are generally yellow to brick red owing to the presence of polysulfides and commonly supplied as a crystalline mass, in flake form, or as a fused solid.
After trying amorphous silicon, he shifted to CdTe and founded Solar Cells, Inc. (SCI) in 1990. [13] In February 1999, SCI was acquired by True North Partners, which then formed First Solar, LLC. [14] [15] At the end of 2009, First Solar had surpassed an energy power production rate of 1 GW [16] and was the largest producer of PV cells in the ...
For example, when the sun is more than about 60° above the horizon (<30°) the solar intensity is about 1000 W/m 2 (from equation I.1 as shown in the above table), whereas when the sun is only 15° above the horizon (=75°) the solar intensity is still about 600 W/m 2 or 60% of its maximum level; and at only 5° above the horizon still 27% of ...
SMA was founded on August 2, 1943 in Florence by Giuseppe Salvini, Lorenzo Fernandes, Enrico Bocci. In 1948, the development of radar equipment was influenced by Nello Carrara . In 1988, the EFIM public group purchased a majority interest in the company's capital, controlling 98.8% of the shares.
