[PDF Version]In order to demonstrate the profitability of the photovoltaic installation, it was assumed that the average price of electricity (including electricity sales and distribution fee) in 2020 was 0.5622 PLN/kWh, and its year-on-year increase will be 3.5% [23, 35].
As the installation has a power of less than 10 kW, 80% of the electricity previously fed into the grid can be obtained for free from the discount system [12, 13]. For the economic analysis it was assumed that the efficiency of photovoltaic panels decreases with time and the energy production decreases by 0.8% year on year .
As prices of all sectors dropped, profit margin of the solar value chain is expected to recover. Polysilicon supply gradually picks up, potentially exceeding demand, resulting in rapid price declines and profit margins shrinking in the second half of 2023.
But a new study by researchers at MIT and the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) shows that other factors are actually more significant — suggesting that the United States could once again become cost-competitive in photovoltaic (PV) manufacturing.

In contrast, the revenues from Ag are 2–4 times the ones from the critical PV fee when the Ag concentration in PVs is 0.2% in the PV throughput range 12,000–15,000 t/yr (at PV throughput 18,000 t/yr the PV fee required to achieve 20% ROI is already negative because the recycling produces ROI higher than 20% even without PV fee).
With RC chargers and balancers, a pack is considered "grossly" out of balance if the cell voltage difference between the lowest and highest is above 0.
Therefore, you should pay attention to the brand from which you are purchasing your batteries. If there is a gap in the voltage of the battery pack, you can correct it with additional equipment, such as with a BMS, balance charging, etc. Stay tuned for Part 2 of voltage difference: How to prevent voltage difference.
If the voltage is below 2V, the internal structure of lithium battery will be damaged, and the battery life will be affected. Root cause 1: High self-discharge, which causes low voltage. Solution: Charge the bare lithium battery directly using the charger with over-voltage protection, but do not use universal charge. It could be quite dangerous.
Generally, SDR is quite low for Li-based batteries but the output impedance may differ by 10%. what is appropriate voltage difference between cells? What voltage difference could indicate that some cells are not as good as others?
