Tom Posted May 9, 2018 Report Share Posted May 9, 2018 Hi How does PV Sol calculate the Energy savings line in the cashflow? What is the formula used? thanks Quote Link to comment Share on other sites More sharing options...
developer_mm Posted May 14, 2018 Report Share Posted May 14, 2018 Hi Tom, Basically, the "Electricity Savings" are calculated as follows: (From-Grid Tariff Energy Price) * (Inflation Rate for Energy Price) * (Degradation of Modules) * (Total Consumption covered by PV power) However, this may differ from the selected feed-in concept. Note, that the savings values are calculated monthly, so that the values can differ from the calculation with annual values.

Tom Posted May 14, 2018 Author Report Share Posted May 14, 2018 Thanks, Marcel for the reply. I have a feed in concept. Can I please find out what the formula will be? Do I just add the feed in sales proceeds? best regards Toim Quote Link to comment Share on other sites More sharing options...
developer_mm Posted May 15, 2018 Report Share Posted May 15, 2018 Hi Tom, the formula would be, as I have shown you, in addition you have to take into account the "annual average return on the capital employed", savings = (From-Grid Tariff Energy Price) * (Inflation Rate for Energy Price) * (Degradation of Modules) * (Total Consumption covered by PV power) / (annual average return on capital employed). savings(Year) = EnergyPrice * (1 + InflationRate)^Year + Degradation * ConsumptionCoveredByPV / (1+ReturnOnCapital)^(Year+1) For example, Energy Price = 0.20 $/kWh Inflation Rate for Energy Price = 2 % / year Degradation of Modules = 100 % (no degradation ) Total Consumption covered by PV power = 500 kWh annual average return on capital employed = 1% savings(Year) = 0.20 $/kWh * (1 + 0.02/year)^Year * 1 * 500 kWh / ( 1 + 0.01)^(Year+1) for year 0 (first year) = $ 99.01 for year 1 = $ 99.99 Kind regards, Marcel Quote Link to comment Share on other sites More sharing options...
