I’m probably doing solar in spring, and I’m paying 20 cents per kwh. It’s about a 13 year breakeven time, but that works for my circumstances. I plan to be here for awhile, my roof faces the right way, and it’s a reasonable diversification of investment.

I’ll still have some dependence on the grid, especially in winter. Might pull from the grid in some early morning hours, but net metering credits should pay for that.

I consider the rising price of electricity and the capital gains from an index funds roughly a wash. It’s not, but I also don’t want 100% of my investments in the stock market, and it’s nice to do something responsible for the world.

So make sure to do your whole installation in one year. You only get to claim the 30% federal tax credit once. So don’t go small with a plan to go bigger later. I couldn’t do this without the federal credit.
