ELECTRICAL QUESTION

want to install in a robust stream. it's about 10'feet wide and has good flow.
when they say 1000watts, what does that mean? I just want to know how much power this stupid thing is going to generate running 24/7/365. Anybody here with enough elcrical to tell me
1000w per second
1000w per minute
1000w per hour
1000w per day
1000w per month

You seem to be confusing Watts, a unit of power (energy/time) with Watt-Hr, a unit of energy (literally 1 Watt for 1 Hr).

So 1000W is exactly that. If it runs at nameplate rating for 1 Hr, it will generate 1000 Watt-Hrs, i.e. 1 kWh.

Making use of such a generator is tricky. The power straight out of the generator may not be very smooth, or it may not be 60 Hz (if it's a simple generator where the output frequency varies with the rotor speed). So it may need to go through a rectifier/inverter. Then if it's a standalone system, you'd need storage (batteries) and a mechanism to instantaneously balance supply and demand. If it's grid-tied, you'd need a grid-tie inverter and the usual permission from the power company, just like a solar installation.

Cheers, Wayne

so if a 1000w generator runs for 1 hour, it will produce 1kwh
so 24kwh hour per day
8760kwh per year
and the power company will credit me .13 per kilowatt hour
so the little hydro-generator in the creek would potentially generate $1138 per year

so I would be better off installing a 5kw hydro generator with a grid-tie inverter

so is it reasonable to conclude that a 10KW will produce approx. $11,380/year
we have a fairly robust creek
