Our expertise

End-to-end service

Our long-term experience, modern technological solutions, and proved standards enable us to carry out the entire photovoltaic system assembly process efficiently.

The technical audit performed by Caldoris Polska specialists permits preparation of recommendations on the selection of optimum equipment parameters and professional preparation and execution of the photovoltaic system assembly.

We support our Customer in the decision-making process by preparing an energy analysis. It consists in examining the energy profile and checking the costs related to electrical energy purchase and distribution. This enables us to propose a photovoltaic installation that is tailored to individual Customer requirements and will ensure the highest rate of return on investment.

We attach great importance to the process of equipment component configuration, which consists in selecting appropriate panels and the inverter, which are suited to the installation capacity. We optimise parameters and select a proper photovoltaic panel wiring and assembly system.

Innovative funding

An innovative model of photovoltaic installation funding permits our Customers to use a modern economically and environmentally efficient energy source without the need to invest considerable own funds:

  • they do not waste their time on seeking funding sources on their own – the purchase is funded by Caldoris,
  • the investment does not require creditworthiness verification by a bank,
  • the purchase does not encumber the Company’s balance sheet,
  • the monthly subscription fee is not subject to indexation,
  • after contract termination, the ownership of the equipment is transferred to the Customer at no extra charge

If the Customer decides to commission Caldoris to deal with utilities supply, we will prepare reliable and comprehensive economic analyses presenting an economic balance for the investment and real future benefits.

Depending on needs, we support also the fundraising process. We monitor the market for the purpose of updating the information about new governmental and EU sources of funding.
