They can cover a part of a household’s consumption and thus reduce electricity bills, especially if the self-generated electricity is self-consumed close to real time. </p><p>Such systems can help make solar energy more accessible, enabling people to become self-consumers even if they do not own a roof or are unable to install solar PV on their roofs. </p><p>Because of their capital needs, they are also more accessible to vulnerable customers due to their low price, especially in Member States that promote their deployment through specific support schemes.”</p><p><a href="https://freiburg.social/tags/Europe" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Europe</span></a> <a href="https://freiburg.social/tags/Solar" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Solar</span></a> <a href="https://freiburg.social/tags/PV" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PV</span></a></p>

balkonsolar<p>Will new <a href="https://freiburg.social/tags/IEC" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>IEC</span></a> Norms kill Plug-in-Pv?</p><p>A new global standard for low-voltage generating sets is currently being discussed by the International Electrotechnical Commission, and somehow in this standard we find section 751.550.101.1, which states:<br>"A generating set shall not be connected to a final circuit."</p><p>The supplementary paragraph 751.550.101.2 is also cause for concern. It states:<br>"The connection of the generating set to the electrical installation shall be made by one of the following methods: […] a dedicated coupling system which is not compatible with any configurations belonging to national systems based on IEC 60884-1.</p><p>This wording directly targets the exclusion of Schuko-compatible plugs. Thus would not allow you to simply connect to the grid.</p><p>The IEC standards are not directly the standards that are in power, but national norming committees use these to draft their rules. So putting something into them that disallows feed in via a standard plug and socket, can make <a href="https://freiburg.social/tags/pluginpv" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>pluginpv</span></a> illegal in many places. </p><p>Any such attempt would grossly underminde the encouragement given to member states in the EU Electricity Market Directive 2024/1711 to allow or promote plug-in solar technology.<br>The comment period ends on June 16th, and not just any citizen is allowed to comment, but only the experts from the national committees.<br>If this becomes a reality, plug-in solar will be a thing of the past for the next few years.</p><p>More Info <a href="https://balkon.solar/news/2025/06/02/will-new-iec-norms-kill-plug-in-pv/" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">balkon.solar/news/2025/06/02/w</span><span class="invisible">ill-new-iec-norms-kill-plug-in-pv/</span></a></p>

On @Grist Akielly Hu asks:

#Balconysolar took off in Germany. Why not the US? - our chair @sbamueller explains: "The 800W threshold is considered low enough that even in the country’s oldest homes, the wiring can withstand (...) even the worst of worst-case scenarios"

The article explains very well what are the next steps the US would have to take to make #pluginpv feasible:

Develop a standard accepted by Underwriters Laboratories and complies with the National Electrical Code. And a compatible ground fault circuit interrupter.

Pictures: Some German Houses with Plugin PV systems on the balcony and elsewhere.

Good news about our #pluginpv project in #Ukraine: “Yesterday we completed the installation of the panel: my husband fixed all the elements and ran the cables to the balcony.”

Our project partners from #EcoClubRivne are checking out how to install #solar on the #balcony. How to set ups such a system with a small battery, because there are lots of #blackouts in Ukraine, due to the destruction of the #powergrid by Russia.

Of course we also try to explore what landlords and gridoperators think and if they try to block small #pv.
