Düsseldorf/ Müns­ter — NRW.BANK is parti­ci­pa­ting in the capi­tal increase of paXos Solar GmbH from Langen­feld as part of its NRW.SeedCap program. The fresh capi­tal will flow into the expan­sion of sales and produc­tion as well as the further deve­lo­p­ment of the next gene­ra­tion of the inno­va­tive multi-energy roof, which gene­ra­tes elec­tri­city and heat directly from the buil­ding enve­lope. The capi­tal increase of paXos Solar GmbH was supported by 15 equity inves­tors, inclu­ding two insti­tu­tio­nal inves­tors — one of which is NRW.BANK.

“Inno­va­tions for climate-friendly energy gene­ra­tion such as paXos Solar show how tech­no­lo­gi­cal progress and sophisti­ca­ted archi­tec­ture go hand in hand in our cities,” says Johanna Anto­nie Tjaden-Schulte, Member of the Mana­ging Board of NRW.BANK.“With our parti­ci­pa­tion through the NRW.SeedCap program, we are speci­fi­cally support­ing the deve­lo­p­ment of sustainable solu­ti­ons from North Rhine-West­­pha­­lia that contri­bute to the successful trans­for­ma­tion of our state.” 

“With NRW.BANK, we have gained a part­ner who belie­ves in the energy of the future — decen­tra­li­zed, aesthe­tic and sustainable. Toge­ther, we are taking the multi-energy roof from NRW to the next level,” explains Kars­ten Birk­holz, Mana­ging Direc­tor of paXos Solar GmbH.

Successful finan­cing round for more growth

The capi­tal increase of paXos Solar GmbH was supported by 15 equity inves­tors, inclu­ding two insti­tu­tio­nal inves­tors — one of which is NRW.BANK. The aim of the capi­tal measure is to further acce­le­rate the growth of the company, which was foun­ded in 2020. The funds will be used to expand sales, increase effi­ci­ency in produc­tion and invest in rese­arch and deve­lo­p­ment for the next gene­ra­tion of products. With the fresh capi­tal, the company is setting the course for the scaling of its sustainable energy solutions. 

Inte­gra­ted energy system for the buil­dings of the future

paXos Solar GmbH deve­lops, produ­ces and distri­bu­tes the so-called multi-energy roof, an inte­gra­ted roof system that combi­nes photo­vol­taics and solar ther­mal energy in an archi­tec­tu­rally appe­al­ing way. This gene­ra­tes both elec­tri­city and heat directly via the roof surface — a space-saving and aesthe­tic solu­tion that meets the growing demands for sustainable, subsi­dizable and high-quality energy concepts for new buil­dings and renovations.
