Hi, I have trouble with financial analysis calculation with and without battery. If I calculate with battery so level of self-sufficiency is bigger but financial analysis tell me that return of assets, amortization period and revenue or saving are same like without battery. The price of both systems are same. When I don´t change price of project and I use battery then assets, amortization period and revenue or saving should be better, not same like without battery. Please tell me when I was do a mistake. Thanks Lukas
