Can I trust a report that does not even have the units right?! Price should be proportional to energy (i.e., Joules or Watt-seconds) not power (Watts).
- acchow 11y agoBoth are relevant. The government and companies probably build capacity in watts (power), but consumers purchase actual joules (energy).
- smac8 11y agoHuh? What's wrong with measuring in price/watt? Price/watt is actually the standard for comparing electricity generation due to not having to create arbitrary units of time to compare with
- _fizz_buzz_ 11y agoNo, it shouldn't be Ws. It's the ratio of the manufacturing cost per rated power of PV-modules.
- ScottBurson 11y agoYou're mistaken. Fuel is sold by price/energy, effectively, but generating capacity is sold by price/power. Since in the case of solar PV, the "fuel" is free, the only cost worth mentioning is the capacity cost.
- gozur88 11y agoInstalled capacity is normally measured in watts. It's really only valuable for trending within the same technology, though, unless you include the capacity factor.
