Factory 2 has 20 fluorescent lighting tubes throughout the factory, which runs for 14 hours every day for operational and security purposes each day 7 days a week for 52 weeks.
The plant and equipment run 12 hours each day 5 days a week for 48 weeks.
The factory does not have solar panels on the roof.
You consult the electricity account for factory 2 and find there is a daily usage of 36 kilowatts-hours per day.
You need to complete the following tasks:
(a) Establish the cost of installing Mono Crystalline solar panels on the roof of the factory,
(b) Establish the cost of installing LED lighting to replace the 20 fluorescent lighting tubes, and
(c) Calculate the expected electricity savings benefit based on the usage mentioned above and the electricity rate for the local provider and installation cost analysis
expected electricity savings should decrease your cash outflows (assume these savings are constant across the period of the NVP analysis)
KWh to kW calculation: The power P in kilowatts (kW) is equal to the energy E in kilowatt-hours (kWh), divided by the consumption time period t in hours (hr) e.g.,:
P(kW) = E(kWh)/t(hr) = 36 kilowatts-hours/24 hours = 1.5 kilowatts
