  2. Cost of electricity by source - Wikipedia

    en.wikipedia.org/wiki/Cost_of_electricity_by_source

    The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...

    en.wikipedia.org/wiki/Engine–generator

    A wattage chart can be used to calculate the estimated power usage for different types of equipment to determine how many watts are necessary for a portable generator. Trailer-mounted generators or mobile generators, diesel generators are also used for emergencies or backup where either a redundant system is required or no generator is on-site.

  4. Panel generation factor - Wikipedia

    en.wikipedia.org/wiki/Panel_generation_factor

    "Total Watt-Hours per Day" = "Total Watt-hours per day needed by appliances" Multiplied by "1.3 times" (the energy lost in the system). Now, to calculate "size of PV cells" OR "number of PV cells" just divide the above obtained "Total Watt-Peak Rating" by "Watt-Peak of each cell OR Watt-Peak of each square meter size", whichever is convenient.

  5. Net metering - Wikipedia

    en.wikipedia.org/wiki/Net_metering

    Net metering enables small systems to result in zero annual net cost to the consumer provided that the consumer is able to shift demand loads to a lower price time, such as by chilling water at a low cost time for later use in air conditioning, or by charging a battery electric vehicle during off-peak times, while the electricity generated at ...

  6. Capacity factor - Wikipedia

    en.wikipedia.org/wiki/Capacity_factor

    The net capacity factor is the unitless ratio of actual electrical energy output over a given period of time to the theoretical maximum electrical energy output over that period. [1] The theoretical maximum energy output of a given installation is defined as that due to its continuous operation at full nameplate capacity over the relevant period.

  7. Kilowatt-hour - Wikipedia

    en.wikipedia.org/wiki/Kilowatt-hour

    All the SI prefixes are commonly applied to the watt-hour: a kilowatt-hour (kWh) is 1,000 Wh; a megawatt-hour (MWh) is 1 million Wh; a milliwatt-hour (mWh) is 1/1,000 Wh and so on. The kilowatt-hour is commonly used by electrical energy providers for purposes of billing, since the monthly energy consumption of a typical residential customer ...
