Even at 40 cents a kilowatt/hour, how can $1000/kilowatt ($1/W) solar panel compete?
Is the $1/W price the one time purchase price or the marginal cost of output over its lifespan?
Most of my electricity bill is transmission fees and depreciated liabilities, that alone has me watching solar very closely.
- Retric 12y agoSolar is priced at the peak output. So 1w solar produces ~8h * 365d * 15 = ~43.8kwh over 15 years. Note, solar lasts longer that than 15 years, but has reduced output as it ages. Also, a major advantage over traditional investments is your saving money which is untaxed and it keeps up with inflation. Generally making it a much better investment than most bonds. A 15 year home loan at 6% is a net win even on a ~5$/w solar system vs 10c/kwh electricity in most of the US. PS: Though for real savings your better going for solar hot water / home heating that generally pays for it's self in under 3 years.
