    Jayrod;3512824]nasa mga naunang posts ko po kasagutan dyan sir. Pakibasa na lang po..

    Idagdag ko pa ito, kaya po sila may promo/sale at 5-yr warranty ng ganung product kasi kaunti ang bumibili.

    Good luck po!
    ah cge, di ko kasi alam kung ano specifically yung binebenta nila.. nakikita ko lang kapag pumupunta ako sa ace....

    hi guys,

    i design and install solar renewable energy anywhere in the philippines whether grid connected or off-grid. i think it's the right time that we use green energy like solar and wind considering the issue about global warming. for solar energy, the initial investment is quite expensive but you'll be your own power plant right in your backyard or at the roof. no noise, no emission, and it's a free electricity as long as there is sunshine you'll have electricity.

    sino may sabi na mas maulan sa pinas, correct me if i'm wrong pero mga 25-30% lang ang ulan dito and your solar panel will still charge kahit maulap/umuulan though not the optimum current compared with strong sunlight. western and european countries encourage their people to use solar and why not here in the philippines. we're a tropical country (init at tag-ulan lang) while these countries have 4 seasons at bakit boom na boom ang solar doon?

    with solar you can significantly reduce you electricity bills and no brownouts of course. medyo mahal nga lang ang solar but educated people knows how they can benefit with it considering the rotational brownouts that happens anywhere in the philippines so they're willing to invest. you can always start off small, say 50W solar panel good for lighting your house all day and night and can use a small wattage electric fan para sa brownout. pwede kang mag upgrade later on as your budget increases.

    thanks ............c",

    ask ko lng panu ung solar power? naiisip ko kasi bat mahal ung mga solar panel bat sa ibang lugar sa pinas meron nun
    sir correct me if im wrong.hindi po sumasabog ang nuclear power plant.mas maganda pa nga ito dahil walang matatapon na kahit anong chemical.sa studies ko po at sarili kong pagkakaintindi about this matter eh using uranium ata un eh malaki ang maitutulong nito para makapag generate tayo ng kuryente.

    kami rin magpapakabit ng electrofix and try ku kung bababa ung consumption nmin sa meralco....sir 5 yrs warranty ba ung sa inio? talaga bang ok cia gamitin?

    mga Sir marami po kc paraan ng pagtitipid ng power energy to save money or reduce electrical bill kagaya po ng paggamit ng aircon mas mainam po na bago sindihan ang aircon ay alisin muna ang init sa loob ng kuwarto sa pamamagitan ng electric fan dahil mas mababa po ang power comsumption nito sa fan ng aircon mas mapapadali po ang pagpapalamig sa maiksing oras mas mababa ang konsumo ng kuryente eto po ay puwedi gawin ng manu-manu or gumamit ng adaptive control na may kakayahan sumukat ng temperature at kontrolin ang aircon at electric fan.maraming salamat po kung makakatulong

    I'm an Electrical Engineer at marami ng kwentong kalokohan na ganyan.

    Dapat sabihin mo nalang a device that can hack the KWH meter! Pero lowering energy consumption??

    Unethical ba?

    Peace bro! Ha, just want you to be educated.

    According to Bernoulli, Energy IN = Energy OUT.



    Di lang masyadong efficient kaya mas malaki kesa rated.


    posible siguro yan kasi sa bahay 1 tym nagkabit erpats ko ng welding machine ewan ko kung anu pwed explanation pero nung nag weweld na sya pabaliktad ikot ng kuntador namin.. Ibig sabihin may way talaga na pwedng pabaliktad ang ikot ng kuntador....

    To clear things out.. There's no such thing as pampababa ng energy consumption. DOn't you wonder bakit around 0-10% lang ang kadalasang maibibigay ng mga tinatawag nilang energy saving device?? It's because they only make your energy consumption more efficient. Yes!!! It's only about the efficiency!

    Kasi ganito yun, energy savers focus on a certain factor to make your consumption more efficient. First, they consider the formula of Power. Power is computed as P=Voltage x Current x powerfactor. In electrical engineering, there are 3 types of power being considered, the True power, Apparent power and Reactive power. Consumptions falls on Apparent power, to imagine this Apparent Power thing, think of a Right Triangle, Apparent is the hypotenuse of True and Reactive. The True power is the adjacent and Reactive power is the opposite.

    Ganito dini:


    Some are using devices that takes enhancement of the power factor, or what we call it power factor correction. Power factor correction lowers the Reactive power and Apparent power, but the real deal is the Apparent power, by lowering it almost equal to the True power.

    P(watts)≈S(VA)

    Ganito kasi yun brad kunwari lang ha, if your CFL bulb wattage is 15watts, then yun ang True power nya, real consumption is higher than 15watts, at yun ang tinatawag na Apparent power. Pero ang unit ng Apparent power is VA or Volt-Ampere.
    To make things efficient, we take power factor corrections.

    Correcting the power factor is to have a unity power factor. The unity power factor is equal to 1, pero only Resistive Loads lang ang may power factor na 1, tulad ng plantsa, Incandescent Bulbs, etc. Ang magagawa lang is to make it almost 1. Kunwari if you have a 0.75 power factor, laking bagay yun! We can make it 0.85 mga ganun using a power factor correction devices like capacitor banks.

    Ganito itsura capacitor banks:


    Example: P=VxIxpf, V=220, I=0.091, P(rated)=15watts, pf=?

    Substituting to formula:

    15=220x0.091xp.f.

    pf=0.749 or 0.75

    but: S=apparent power, power being used.

    S=P(rated)/power factor = 15watts/0.75 = 20 Volt-amperes or 20VA

    Correcting,

    (kunwari nacorrect na natin using a proper capacitor banks kasi mahaba ung formula ng kupitan, )

    Assuming pf(corrected)=0.90 (Ang galing!!! 0.90 sa 15watts??!!! WTF??!!)

    .: S = 15watts/0.90 = 16.67 VA nalang!!

    Yan ang point of view ko.

    Others naman yung nakita ko sa IIEE Convention, they lower the voltage.

    Since, P is directly proportional to Sinusoidal Current, Voltage and pf. They lower the power din!

    Disadvantage, pag electric fan, mabagal din ang ikot, %slip mataas din!

    Using a transformer to lower voltage to 110 is not ideal!

    It may make your consumption bigger kasi may efficiency din ang mga transformer tsaka tumataas naman ang current kahit pababain mo ang voltage, that does not make any sense! Tapos lalaki pa ang conductors mo, kasi Surface area of conductors is directly proportial to current but inversely to voltage.

    15watts(in 110v) = 15watts(in 220v) = 15watts(in 12V) = 15watts(in any Voltage)

    Ang hirap layman's mga to.


    Hypothesis:

    Ang tanging masasabi ko lang, pag di naman mala-industrial ang bahay nyo, mas maiigi magtipid ka nalang, dagdag consumption mga electric saving devices na yan if less 10,000 pesos binabayaran sa bahay nyo.

    Electrical Engineers, correct me pag may mali.
    Oh my. . sana di mo nalang pinakita 'to-nagdugo utak ko :/
    haha, just kidding

    conver your house to 110v.

    sure na bababa ang consumo ng kuryente nyo kasi sa 110v na mababa sa 220, mas mababa ang energy loses.
    Wrong info, mas malaki ang system loss sa 110volts. The higher the Voltage the lower the resistance thus lower loss.
