rafal

Let's say I produce 10 000 kWh/a and I need 4 000, but in my country I have no net metering. I want to count the profit as = 4 000 kWh * price I would have to pay to purchase energy from grid distributor + 6 000 kWh * price I will obtain for selling the energy How can I make a custom tariff like this? I tried a bit in the program but calculations didn't go as expected (I got bigger profit that I should have)
