Many photovoltaic prosumers on net-billing are considering expanding their system with an energy storage. The transition to hourly billing at RCE rates on the one hand, and the Mój Prąd 6.0 subsidy on the other, encourage adding a storage to the existing photovoltaic system. Especially since many prosumers have already partially prepared for such a step and their set is equipped with a hybrid inverter. In this video, I perform hourly calculations for a real photovoltaic system and show how installing a storage would translate into savings on electricity bills and profits from selling energy to the grid. By relating this to the value of the investment and the amount of the subsidy, I calculate the return on such an investment. For a more complete picture, I compare storages with two different capacities. I consider both the case in which the prosumer would receive the Mój Prąd subsidy and the case in which he would not receive it. 00:00 Expansion of the PV installation with an energy storage 00:45 Assumptions for calculations and input data 03:54 Results of hourly analysis with medium and larger energy storage 07:12 Adding a storage vs. staying with PV only 10:43 What if there is no subsidy? 15:59 Your case is different This is just one analysis. Over the past months of performing various simulations, as well as checking real prosumer bills on net-billing, I have drawn many conclusions that I would like to share with you in the Photovoltaics 2024 course. Net-billing from A to Z. Visit the website: www.kurs-netbilling.pl and learn more. I also invite you to join the webinar, in which I will show you what you will find in the course itself. But before we get to that, we will calculate, perhaps on the assumptions given in the chat, whether photovoltaics is still profitable. https://czy-pv-sie-nadal-oplaca.grweb...
