hi sir,
i based the power consumption from the panasonic website.
PV8
http://www.panasonic.com.ph/web/pid/5753/Spec
pv8 is 335watts for normal usage. also just to add, i read somewhere before that plasma consumes 800w or more for the 1st 15 minutes of use.
That's maximum power draw which is not constant in the case of plasma and LCD. Manood ka ng puro madilim sa madilim na room and at very low picture settings then lalabas pang matipid pa sa LCD ang Plasma. Ang relevance lang ng data na yan is that your electric line should be able to supply that much power with sufficient tolerance not only for your house's safety but also for the equipment's. Para ring PSU unit ng PC. Yes I think Plasma would likely consume more power during the 1st few minutes, but 800W for a PV8 for 15 minutes? Yung ganyang klaseng spike happens only for AC motors within very few milliseconds hence overcurrent or thermal overload relays are provided sa electric switchboard. Even the 65V does not reach that high. Baka yung 103V pa.
Look for "annual power consumption" because that study is based on actual usage over a fixed period of time that other Japanese makers are also following as standard. Yun ang mas madaling gauge ng babayaran mo sa Meralco or whoever is your electric utility company. It seems sa Japan lang sila nag-pu-publish ng ganon data.
Im using a 50V full HD plasma and a 37 inch LCD. Di ko makita effect ng isa't-isa sa kWh reading ko monthly. But if I use aircon or electric heater kahit sandali lang, dun ako pulbos.
