Soloof House Energy Solution (SHES) for Apartment Buildings

  • Do you want your ten­ants to ben­e­fit direct­ly from elec­tric­i­ty gen­er­at­ed by the building’s roof?
  • Do you want to be able to offer elec­tric­i­ty to your ten­ants, increas­ing your rev­enue while allow­ing them to ben­e­fit from afford­able pow­er?
  • Do you already have a pho­to­volta­ic sys­tem installed but lack a solu­tion for dis­trib­ut­ing the elec­tric­i­ty to dif­fer­ent ten­ants?
Then the SHES is your solu­tion. SHES offers an inno­v­a­tive, legal­ly com­pli­ant, and cost-effec­tive solu­tion for the dynam­ic sup­ply of var­i­ous ten­ants. You and your ten­ants ben­e­fit direct­ly from the gen­er­at­ed elec­tric­i­ty – with­out detours through the pub­lic grid.

⚙️ System Setup

The set­up is out­lined in the image above:

  • A pho­to­volta­ic sys­tem is locat­ed on the roof. Its dimen­sions are deter­mined sole­ly by the roof’s size, not by the poten­tial con­sump­tion of indi­vid­ual ten­ants.
  • A cen­tral con­trol unit directs the elec­tric­i­ty either to the house­holds or charges a bat­tery.
  • Each house­hold has its own elec­tric­i­ty meter and an invert­er which con­verts the direct cur­rent from the rooftop sys­tem into alter­nat­ing cur­rent.
  • The invert­er ensures that no elec­tric­i­ty flows from the grid towards the bat­tery and also that no more elec­tric­i­ty flows than the house­hold is cur­rent­ly con­sum­ing. This so-called zero feed-in legal­ly ensures that the sys­tem oper­ates com­plete­ly inde­pen­dent­ly of the pub­lic pow­er grid.
  • The elec­tric­i­ty meter is MID-com­pli­ant. Its read­ings are there­fore rec­og­nized as cal­i­brat­ed by the tax office. Legally, the sys­tem oper­a­tor sells the com­mod­i­ty of elec­tric­i­ty to the ten­ant. Consequently, the tax­es for the sale of elec­tric­i­ty apply. We offer the ser­vice of han­dling the account­ing for both the tax office and the ten­ant.
  • You have the choice of whether you wish to own, build, or oper­ate the sys­tem your­self.

📈 Benefits for Property Owners

  • Cost-Effectiveness: You achieve high­er rev­enue. SHES sys­tems pay for them­selves for most build­ings with­in 4–7 years.
  • Value Appreciation: Properties with their own ener­gy gen­er­a­tion will be val­ued high­er in the long term com­pared to those with­out.
  • Attractiveness: You can offer your ten­ants cheap­er elec­tric­i­ty. Your ten­ants start sav­ing direct­ly from the first month.
  • Legal Security: SHES sys­tems are designed for self-con­sump­tion. Since no ener­gy is fed into the pub­lic grid, they are not sub­ject to EU rules for pub­lic net­works.
  • Future-Proof: SHES sys­tems can be built using com­po­nents (bat­tery stor­age, invert­ers, etc.) from var­i­ous man­u­fac­tur­ers. Therefore, if com­po­nents fail, they can be reli­ably replaced. Furthermore, the sys­tem can be expand­ed or adapt­ed at any time.

✅ Benefits for Tenant

  • Lower Electricity Price: Direct pur­chase of solar pow­er with­out grid fees and mar­ket fluc­tu­a­tions.
  • Freedom of Choice: The exist­ing elec­tric­i­ty sup­ply con­tract is main­tained. Tenants can con­tin­ue to buy elec­tric­i­ty from the sup­pli­er of their choice. A ten­ant is not required to par­tic­i­pate in the SHES, but legal­ly, par­tic­i­pa­tion must be offered to them.
  • Transparency: Each house­hold can see the avail­abil­i­ty of elec­tric­i­ty from the roof and adjust its con­sump­tion behav­ior accord­ing­ly.
  • Sustainability: Also as a ten­ant, one can con­tribute to a bet­ter cli­mate.

💡 Conclusions

With the SHES, a mul­ti-unit res­i­den­tial build­ing becomes an ener­gy-effi­cient build­ing. Owners ben­e­fit from a secure invest­ment, ten­ants ben­e­fit from afford­able and sus­tain­able ener­gy – and every­one con­tributes to the ener­gy tran­si­tion.
