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.

Basic simple calculation for one entry (optimal variant for the entered consumption - 1 x calculation)

DESCRIPTION

optimal performance of PV plants
optimal PV power and BESS capacity (taking into account the limitation of flow into the grid)
optimal PV power and BESS capacity with the aim of limiting the maximum taken
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)
optimal FVE output to the specified BESS (taking into account overflow limitation / reduction of maximum consumption)

NOTE: the resulting report includes only one solution of the calculation from the list above based on the customer’s criteria

INPUT DATA conect
