Do you know what optimal power of your photovoltaics and battery capacity should be for real operation of your company, office or factory?

Our Photomate analysis will that provide to you based on your electricity consumption time chart, not according to the size of the roof! Overall economic evaluation effectiveness of investments in the installation of PV plants and battery storage:

A) Comparison of the time chart of production and consumption of elektricity

B) Investments and revenues during operation PV and battery storage

C) Net present value, index profitability and payback period

D) Simplified economic analysis from the specified time chart of consumption

E) Detailed analysis

  • Detailed consumption analysis (detailed measurement)
  • Assessment of possible savings in cash on delivery payments elektricity
  • Economic evaluation savings in case of PV installation
  • The economic benefit of PV
  • Comparison of the time chart of production and consumption of elektricity

A - Basic

Optimization of PV + BESS + CONSUMPTION energy management design based on input data sent by the client.


DESCRIPTION
  1. optimal performance of PV plants
  2. optimal PV power and BESS capacity (taking into account the limitation of flow into the grid)
  3. optimal PV power and BESS capacity with the aim of limiting the maximum taken
  4. optimal capacity of the BESS to the specified power of the PV plant (taking into account the limitation of the overflow / reduction of the taken maximum)
  5. optimal FVE output to the specified BESS (taking into account overflow limitation / reduction of maximum consumption)

INPUT DATA conect
  1. PURCHASE price energy per 1 MWh
  2. DISTRIBUTION price (use of networks) per 1 MWh
  3. MAXIMUM of taken energy, price per 1 MW (or Amps/circuit breaker)
  4. OTHER PAYMENTS (system tax according to local legislation) per 1MWh
  5. OPERATING internal COSTS EUR/year
  6. SALES price of electricity per 1 MWh
  7. SUBSIDY for FV and BESS (% of investment costs)
  8. 15 minutes POWER values per calendar year in the defined.xls format OR 60 min POWER values per calendar year in the defined.xls format (however, lower calculation accuracy is achieved)

OUTPUT DATA conect (PDF file format)
  1. Estimated total annual power balance
  2. Estimated investment costs
  3. Net present value 20 years
  4. Profitability index for optimal solution
  5. Return of investment for optimal solution
  6. Graphical and tabular outputs of production, consumption, supply to the network, withdrawal from the network, calculation of savings by month
  7. Calculation of the possible annual savings during the implementation of the proposed measure for the option of reducing the maximum
