You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 54.174.0.0/16 has been blocked (disabled) by ‪JJMC89‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 05:35, 2 May 2025.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

'''Bosch Solar Energy AG''' was a German [[solar wafer]] and [[solar cell]] manufacturer, based in [[Erfurt]], which specialized in [[crystalline silicon]]-based [[photovoltaic]] (PV) products, as well as [[thin-film solar cells|thin-film modules]] using amorphous silicon and CIGS absorber materials. The company consisted of various divisions for silicon, wafers, solar cells and modules, research and production facilities in [[Germany]] and [[France]] and plans were made to open a production line in [[Malaysia]].<ref name="bosh-exit-photon" /> It has been listed on the German stock exchange since 30 September 2005 and on 19 December 2005 its shares were admitted to the [[TecDAX]]. The enterprise was founded in 1997 as ErSol Solarstrom GmbH & Co. KG.((Citation needed|date=March 2023))

In 2013, [[Robert Bosch GmbH]] announced that it will exit from the solar business. [[SolarWorld]] took over production in [[Arnstadt]] and continued to employ about 800 workers.<ref>((Cite web |date=26 November 2013 |title=SolarWorld signs deal with Bosch to buy cell and module facilities in Germany |url=http://www.pv-tech.org/news/official_solarworld_signs_deal_with_bosch_to_buy_cell_module_facilities_in |archive-url=https://web.archive.org/web/20131129101038/http://www.pv-tech.org/news/official_solarworld_signs_deal_with_bosch_to_buy_cell_module_facilities_in |archive-date=2013-11-29))</ref>

==Structure and products==
Bosch Solar Energy is subdivided into four different divisions according to product groups. The various subsidiaries are responsible for these divisions:
*''SRS Silicon Recycling Services'' The Bosch Solar Energy subsidiary SRS Silicon Recycling Services, Inc., specializes in the recycling of silicon. The scope of the ersol Group subsidiary currently covers silicon for solar and semiconductor applications, metallurgical grade silicon and support products. All grades of silicon.
[[Image:Klassieren.jpg|thumb|monocrystalline solar cell]]
*''Bosch Solar Wafers'' Bosch Solar Wafers GmbH is a specialist manufacturer of monocrystalline ingots and wafers. The Bosch Solar Energy subsidiary currently produces the following products:
** Monocrystalline silicon ingots
:: (p- and n-type)
** Monocrystalline silicon wafers
:: (p- and n-type)
** Crystals and wafers with special twin structures.
*''Solar Cells'' produces [[solar cell]]s in the format 156&nbsp;mm x 156&nbsp;mm and is the core business sector. At a thickness of 200&nbsp;µm and less, the average efficiency of [[monocrystal]]line ersol solar cells is around 17%. The share of production dedicated to higher-grade monocrystalline cells compared to [[Polycrystal|multicrystalline]] solar cells is increasing and currently stands at about 80%. The parent company Bosch Solar Energy AG is responsible for production at its plants in Erfurt and Arnstadt.
*''Bosch Solar Modules'' is accountable for all group activities relating to the production and sale of [[Photovoltaic module|solar modules]]. The division incorporates Erfurt-based Bosch Solar Thin Film GmbH, which is devoted to the production of thin-film solar modules and achieves significant savings in the raw material silicon with the aid of thin-film technology. In addition, ersol markets crystalline solar modules from solar cells produced by ersol and other manufacturers through its Erfurt-based trading subsidiary Bosch Solar Modules GmbH. The division also has a crystalline module production line at the planning stage.

== Management board ==
The management board of Bosch Solar Energy AG consists of four members:
*Holger von Hebel, [[Chief executive officer|CEO]] (responsibilities: Corporate Development, Finance/Controlling, Human Resources, Corporate Communications, IT, Legal Affairs and Post Merger Integration)
*Dr. Volker Nadenau, [[Chief technical officer|CTO]] (responsibilities: Research & Development, Process Development and Photovoltaic Strategy)
*Jürgen Pressl, [[Chief operating officer|COO]] (responsibilities: Manufacture of Ingots, Wafers, Solar Cells, Crystalline and Thin-film Solar Modules, Purchasing/Supply Chain Management)
*Peter Schneidewind, [[Chief sales officer|CSO]] (responsibilities: Sales, Marketing and Product Management)
