The Electricity Saving Thread

Meralco has FINALLY come up with a Net Metering scheme. Anybody interested in pursuing such an implementation?

Lighting for my house has been offgrid for 10 months now, saving more or less 1k a month with just 240w of solar panel and battery.

Since legal na ang net metering, iplan to upgrade the rest of the house to a 1kw on grid system. Low consumption lang naman ako pag umaga bihira aircon and para mag negative ang metro ko, and just use meralco at night. Been scouting the green power exhibit at smx, madaming option don.

kung nag pro-produce ka din ng electricity pwede ito, kung meron kang wind turbine or solar panels,

ung ROI nga lang hindi attractive kasi malaki ang investment mo compared sa returns.

How about maintenance? How often would you clean your panels? You did anything to manage heat? Thanks.

whats a NET metering scheme? I have one of their Time of Use meters (where they charge less at night but more during daylight hours) . My bill went from 20k month to about 13k a month so far.

It's an arrangement wherein establishments install mechanism(s) like solar panels, windmills, etc. to produce electricity that is fed directly into the grid. No need for storage like batteries that is susceptible to energy loss and adds to the traditionally high costs of such implementations.

Electricity produced is then is credited to your periodical electric usage.

In other words, with those in place, and you're not using any electricity, your meter will actually go backwards.

thanks for the info! Didnt know that. Not sure though if the infrastructure is in place for subdivisions and such. Maybe in industrial areas this would be more applicable. But it would be nice to have it in residential areas.

I have heard of prepaid electric meters but meters actually going backwards? this is something new.

How much is 240w of panels nowadays, if you don't have to buy storage?
