RENTAL AND SERVICE PLANTS

Rental and service plants model enables the client to earn profit from electricity created by the solar power plant without making an initial investment. All that is needed is a suitable plot of land — Solar Wheel takes care of everything else.

At first, the owner of the property has to decide if they (a) want to earn rental income from renting the necessary plot of land for constructing the solar power plant, or (b) order the construction and operation service with the objective of becoming a solar power plant owner in the future. The following graph presents the main differences of a service station vs a rental station.

Service contract

Fixed service fee
(Solar Wheel makes the initial investment and operates the SPP; the customer is billed by a fixed periodic fee)
Fixed periodic fee
(the service period is usually 6-10 years, after that the end client assumes ownership of the SPP)
Connection contract with a network company on behalf of the client
(received profit covers both service fees and renewable energy charge)

End client

Landowner who owns the property where the solar power plant (SPP) will be built
Solar power plant (SPP)
Produces electrical energy (kWh)
Energy sale (market price, ca 0.05€ / kWh).
Received by the owner of the network company contract
Renewable energy charge (0.0537€ / kWh).
Received by the owner of the production equipment

Solar Wheel

  • Invests in building the SPP, takes the solar plants in it’s balance;

MAINTENANCE

Structure maintenance
  • Check-up for the mounting structure’s, foundation, frames, screws and bolts.
Production data analysis (constantly)
  • Production data is compared to plants of the same type constructed in Estonia at the same time, this will help identify anomalies. The client also has access to production data.
Regular handling and maintenance of the electrical installation
  • Electrical connection check-up - once a year - all electrical connections (DC and AC) will be checked.
  • Panel check-up (degradation and hotspot analysis) - once a year.
  • Visual check-up of the condition of panels (cracks, changes in color).

T1
12 year plan - 50 kW ground plant

Premises

  • Your connection contract enables consumption current of 80A or it is possible to increase the main fuse
  • The productivity of the solar power plant is 55 000 kWh / year
  • The solar power plant produces only for the grid, meaning there is no self-consumption.
