Good luck. Also, at least in the US you’re looking at 30% federal and possibly state incentives plus again savings being tax free.
And don’t forget about inflation when doing your ROI and invest returns calculation. US electricity prices averaged 16.04c/kWh March 2023 to March 2024, but 15.50c/kWh March 2022 to March 2023. https://www.eia.gov/electricity/monthly/epm_table_grapher.ph...
As to liquidity, the stock market may be a better long term investment but it’s quite risky even over surprisingly long periods.
