Solar­Cloud is the next dig­i­tal prod­uct to arise from the coop­er­a­tion between Kiwigrid and the inno­gy Group

  • Solar­Cloud makes it pos­si­ble to store the solar ener­gy gen­er­at­ed in sum­mer for use in win­ter
  • The Kiwigrid plat­form is the IoT- and soft­ware-based back­bone of this inno­va­tion


Vir­tu­al stor­age of solar pow­er – now pos­si­ble thanks to the inno­v­a­tive Solar­Cloud, which the Essen-based ener­gy com­pa­ny inno­gy pre­sent­ed at Inter­so­lar 2018. Kiwigrid’s ener­gy ser­vice plat­form serves as the IoT- and soft­ware-based back­bone of the vir­tu­al solar ener­gy stor­age. When it comes to dig­i­tal ener­gy ser­vices, the Dres­den-based com­pa­ny has been the strate­gic part­ner of inno­gy and the envi­aM Group since last year.

Today, many cus­tomers rely on ener­gy stor­age sys­tems to enable them to use their self-gen­er­at­ed solar pow­er more flex­i­bly. How­ev­er, phys­i­cal stor­age devices hit their lim­its if, for exam­ple, they are tasked with stor­ing the solar ener­gy pro­duced in sum­mer for use in win­ter. After all, the elec­tric­i­ty that’s pro­duced in sum­mer would be an ide­al sup­ple­ment to the self-gen­er­at­ed elec­tric­i­ty dur­ing the dark win­ter months when PV sys­tems pro­duce almost no solar pow­er on some days.

The heart of Solar­Cloud: the Kiwigrid plat­form

This is pre­cise­ly why LEW led the charge in devel­op­ing Solar­Cloud for inno­gy and envi­aM, which enables vir­tu­al stor­age of solar ener­gy. The Kiwigrid plat­form is the IoT- and soft­ware-based back­bone of Solar­Cloud and the home ener­gy man­age­ment sys­tem solu­tions of the entire inno­gy Group. “We com­bine the solar sys­tem, ener­gy stor­age, and Solar­Cloud into one smart and cus­tomer-cen­tered sys­tem. We will con­tin­ue to devel­op the prod­uct fur­ther in con­junc­tion with inno­gy and the envi­aM Group”, adds Tim Ulbricht, Man­ag­ing Direc­tor of Kiwigrid.

The Dres­den-based com­pa­ny spe­cial­izes in con­nect­ing and orches­trat­ing many small-scale dis­trib­uted ener­gy resources to form one sys­tem and already man­ages mil­lions of data points of con­nect­ed decen­tral­ized devices on its plat­form. This is Kiwigrid’s basis for its numer­ous ser­vices, which include sys­tem inte­gra­tion, instal­la­tion sup­port, and strate­gic con­sult­ing.

Mar­tin Her­rmann, Sales Direc­tor at inno­gy: “The sun often shines most intense­ly when the elec­tric­i­ty con­sump­tion in the house is at its low­est, name­ly at noon. Almost every sec­ond home­own­er there­fore sup­ple­ments their pho­to­volta­ic sys­tem with a bat­tery. Our vir­tu­al stor­age, which can also be used as a stor­age expan­sion option, now makes it pos­si­ble for PV sys­tem own­ers to use the elec­tric­i­ty gen­er­at­ed on their own roof more effec­tive­ly.”

Open sys­tem for easy inte­gra­tion of new devices

Solar­Cloud takes the solar prod­ucts from inno­gy, envi­aM, and LEW to the next lev­el. Kiwigrid advised on the devel­op­ment of Solar­Cloud and imple­ment­ed the appro­pri­ate busi­ness log­ic. All com­po­nents are inte­grat­ed and con­trolled via KiwiCloud and the KiwiOS ener­gy man­ag­er. Since the Kiwigrid plat­form is an open sys­tem, inte­gra­tion of addi­tion­al devices is pos­si­ble at any time.


About inno­gy SE

inno­gy SE is a lead­ing Ger­man ener­gy com­pa­ny with a turnover of around 43 bil­lion euros (2017), more than 42,000 employ­ees, and oper­a­tions in 16 Euro­pean coun­tries. With its three divi­sions (Renew­able Ener­gies, Net­work and Infra­struc­ture, and Sales), inno­gy address­es the require­ments of a mod­ern ener­gy world that is decar­bonized, decen­tral­ized, and dig­i­tal. Innogy’s oper­a­tions are cen­tered on our more than 22 mil­lion cus­tomers. Our goal is to offer them inno­v­a­tive and sus­tain­able prod­ucts and ser­vices that enable them to use ener­gy more effi­cient­ly while improv­ing their qual­i­ty of life. Our key mar­kets are Ger­many, Great Britain, the Nether­lands, Bel­gium as well as sev­er­al coun­tries in Cen­tral East­ern and South­east Europe, espe­cial­ly the Czech Repub­lic, Hun­gary, and Poland. With a total capac­i­ty of 3.9 gigawatts, inno­gy also gen­er­ates pow­er from renew­able ener­gies out­side of these regions (e.g. Spain, Italy, and the U.S.). Being an inno­va­tion leader in for­ward-look­ing top­ics such as eMo­bil­i­ty, we are rep­re­sent­ed at the tech­nol­o­gy industry’s inter­na­tion­al hotspots such as Sil­i­con Val­ley, Tel Aviv, or Berlin. We com­bine the broad know-how of our ener­gy tech­ni­cians and engi­neers with dig­i­tal tech­nol­o­gy part­ners – from start-ups to large cor­po­ra­tions.
