Appliance Kilo Watt Hour Calculator

The problem today is that everyone can conveniently argue that there are cost savings by using solar electricity as an alternative energy source. However, there are few or no established models to determine the price paid to enjoy such savings. This leaves homeowners nervous about whether or not they can afford to go solar. As a result, many who may be able to afford solar do not complete the Free Quote Form because they don’t want to be on a list and embarrassed when the price is too high. But there is a way to minimizing the surprisingly high cost of solar PV. Perhaps, one of the first approaches is to estimate appliances energy consumption by using manual method or a kilo watt hour calculator (kWh).

Kilo Watt hour (kWh) Estimation: The First Prerequisite

Thus, the first step required to estimating the price to be paid for a solar PV kWh is by looking inwards to determine the appliance energy consumption. This is the same position by many scholars who at various times stated that the most important and complex stage in sizing an off-grid PV system is providing the daily electricity consumption in a carefully worked out and breakdown format (James, 2008: p. 317; Falk, et al, 2010: p. 185).

Therefore, our Appliance kWh Calculator will help would-be solar PV owners to easily estimate the energy consumption of all the appliances to be hooked to the solar system. It also helps them have an insight about the energy consumption of each appliance before taking the next step of selecting a solar battery that will provide the required energy for such appliance. Note that the battery is the energy store-house of the solar system and it is often not practical for any battery to supply more energy than it is rated for.
