It’s been a while since I considered solar energy. Then it was becoming competitive. Now it surely is competitive with oil companies investing in it just to hedge their bets. Thanks to global markets, Chinese industry and some other factors, prices have plunged.
Think of it. Here, we often have cold windy winters but lots of sunshine. If I had a south-facing roof full of these things, I could easily get ~10KW of power during a few hours most days, enough to heat my house. When it’s -30-40C and 40km/h winds, that’s a valuable aid to the budget. Say, 40kwh daily at 10 cents per kwh, that’s $4/d. These things would easily pay for themselves in 10 years and last 25 years. I could even spring for some NiFe batteries or something else to store energy for the rest of the day. It’s all good. I could add some wind to this as well. I sense a project for next year, another reason to keep on living. Imagine if I lived in a tiny shack in the bush… I could easily be self-sufficient.
