The nuances is essential to know while connecting private solar power plant (SPP) to the power grids of Oblenergo

No wonder people say: "Forewarned is forearmed" as there are many obstacles that can confront private home owner who has decided to build a private SPP. We can share some of them on the basis of the experience gained.

nuances of spp connections to the power grids

OBTAINING OF THE LICENCE

The big advantage for implementation of private SPP is the lack of requirements for obtaining a license to produce electricity.

Construction of private SPP differs significantly with the lower cost and smaller scope of work required compared to construction of the industrial SPP.

DEVELOPMENT OF THE DESIGN

There are no legislative requirements regarding mandatory drafting of the SPP design.

Nevertheless development of the design provides the following advantages:

  • selection of the optimal equipment (model, quantity, cable length); determination of the SPP cardinal orientation; modelling to determine the solar activity; evaluation of the adjacent objects (buildings, trees, etc.) impact on SPP; selection of the optimal angle and best distance between the panel series. Therefore design determines the most advantageous option for SPP construction.
  • reduction of the construction works duration of and set-up of the SPP operation mode by the service company.

OBTAINING OF THE "GREEN" TARIFF

  • The difference in purchase/sale of the electricity produced by private SPP compared to industrial SPP (legal entities) is that the contract should be concluded with Oblenergo and not SE" Energorynok".

INCREASING THE CONNECTED CAPACITY

Successful obtaining of the expected value of the "green" tariff depends on the quality of performed audits of documents. Sometimes it happens so that the owner of the private house needs to increase the connected capacity, but Oblenergo could not technically provide such service. In such cases, home owners could still wait for the moment when Oblenergo would be able to ensure capacity increasing or to perform rehabilitation/construction of the power grids for his own cost.

ELECTRICITY ACCOUNTING

Oblenergo is engaged in arrangement of the metering unit, but depending on where it would be placed (on the front of the house, on a support or elsewhere) the electricity losses (in power line, transformer substation) should be considered when reporting to the limit of balance affiliation. So, the greater would be distance from the inverter to the commercial accounting unit (counter), the greater would be loss of electricity produced via SPP and the less costs Oblenergo would pay.
