Solar Powered Home

[NightRock]

Anyone have done this on thier own house?? I saw in the news that SM North is now powered by SOLAR..(Anak ni Loren Legarda yung Founder)..

I'll been dreaming of this business to start more than a decade ago in Philippines, when I was incharged of installing thousands of solar panel in our Oil Wells in middle east for powering our data communication and transmission. During that time most of my staff are pinoys and they explain it to me how good it is but it needs a huge investment. Now I don't know where they are. I'm thinking to power my house thru Solar. I have 125 sqm garden and I'am planning to install Solar Panel on that area to cover the whole garden and it can also served as a roof (rather than putting the solar panel in the house roof).

Any one have tried this in philippines I have seen a lot of this in UK. Any one knows a good contracting company that can do this Job.

Meron sa cavite, i forgot the name.

I think it's better if you find out more about which type you really like. Do you want it on-grid or off-grid?

Sayang, sa ibang countries like australia, pag may excess electricity ka from solar array mo, pwede mo sha isauli sa power companies (distributors) - they either pay you like they do power producers, or at least give you a rebate sa electric bill mo.

Yung renewable energy law natin meron nang provisions for that - wala lang talaga kwenta implementation ng executive department natin.

Imagine kung lahat ng bahay sa mga first class subdivision or village i required na mag installed ng Solar malaking tulong sa goverment yon nama bawas ng load sa power grid.

On my requirements I think it is better to have options on/off grid so during rainy days na mahina ang sikat ng araw I can still use normal power from Meralco.

Mahal kasi sir ang gumawa ng solar array eh. And usually talaga pag residence on-grid gamit.

Eto sir mahahalikan moko sa matutunan mo dito:

maraming episode yan.

Nagresearch na rin ako jan dati - pinakamura yung gawang china. In a few years pakiramdam ko magmumura cost ng solar energy system components. lalo na't nagkikick in na mass production.

[crosswind]

di na kailangan niyan
sabi nga diba ni Pnoy
Pano pag walang araw?

[NightRock]

nag kalat na nga ang mga Solar panel na made in China.. I think in few years time mag boom na din yan at marami na mag kaka interest na pasukin ang business na yan like CCT installer nag kalat na so pag dami ng demand and supply mag mumura din yan.. But for now I am considering investing on it but I prefered off grid nag research pa ko magkano ang preso ng mga good quality battery.. If only I can take those battery I have from my contractor hehehe kaya lang ayoko mawalan ng work better pay it on my hard earned money rather than stealing it from the company and lossing my job.

Hehe... pero shempre sir you want to start it right. Morality is a slippery slope. If we allow ourselves do small bad things, it would lead to us doing more.

Malamang magmumura talaga yan sir. Im also planning a business set-up like this but for transport operations. Shempre di ko pwede idetalye. hehe.

China brands of course not good as their US counterparts, pero the decrease in efficiency is offset by the price.

In terms of battery, malaki talaga energy waste jan sir. Pinakaefficient as of the moment mga lithium-iron-phosphate batteries.

Consider mo sir kung more of DC or AC mga appliances/loads na gagamitin mo. Pag nagcoconvert kasi from DC (which is the current created by the solar panel, unless may microinverter sha) to AC, may losses ulit. On the average, a solar array set up with AC loads and a battery set-up (para may kuryente ka kahit gabi) has around 30-60% energy waste. So important na you decrease your need and plan your loads.

Pag saktuhan lang kasi yung set-up mo, magdagdag ka lang ng electric fan magugulo na agad yun. lol. kinocompute pa yang load kasi.

[yebo]

pwede mo naman ihiwalay yung loads sa bahay, like pwede mo gawin na yung solar power system mo only supplies power to lights and TV. just install a double throw transfer switch so you have an option pag walang charge ang battery.

Anybody who can give me a rough investment figure if I want to 'solarize' my home datacenter? It is currently averaging 150W (210W peak) running 24x7. I'm actually spending somewhere in the neighborhood of P1.5k a month on electricity bills to run it.

If I were to put up some solar panels to at least support 50-75% of that load, how much would that system cost and what will be its lifespan? I can compute for the ROI but if it can be provided as well, it would save me the trouble.

Korek po si sir

In my limited knowledge, my answers:

1. there are a number of installers in RP who could answer you on this one.
2. If you wish to power only a part of your load, you need to segregate them. Meaning, choose which of your loads would be powered from your solar array and which would come from the grid. So assuming your example of 150KW is made up of 10 appliances taking up 10KW each, then choose the 5 loads that you would power with a solar array that delivers 75KW (place some allowance.)
3.Residence-grade solar system set-ups are not that flexible, meaning kapag ang need mo ay somewhere around 150kw-210kw, you need a set up that could deliver the 210kw (with allowance) and the rest of the energy is either stored or wasted.
4. There is a lot of wasted power depending on your set up.
5. Mejo mahal na ang 150KW set up sa palagay ko. According to my readings, it takes about 10-14 years para sa ROI ng solar array mo. However those figures are based in the US and our difference with them are as follows:
a. Their solar panels cost more (ung ginamit sa nabasa ko, sorry nakalimutan ko kung saan), while China brands are so much cheaper and are GETTING even cheaper. Pero isang component pa lang ang solar panel, marami pang iba.
b. Lifespan ng US made panels are guaranteed to be longer. China brands are relatively new and have not yet proven lifespan
c. Mas Mataas ang solar radiation received ng Philippines per capita. Meaning kung same panel, mas malaki production natin kesa per capita ng US
d. Mas mainit sa atin - decrease ng efficiency ng solar panel from 10-30% kung kasama pa dust, etc.

In short, hindi ko alam sagot. Sorry for wasting your time. LOL

seriously, meron naman sa pinas. per it pays to understand it para hindi ka maovercharge.=)

^ I just need to power up the datacenter... It uses around 110kW-h a month on average (150W for 24 hrs x 30 days)... not the whole house.

[NightRock]

I contacted 3 contractor they will give me the quotation as per my requirements I gave. Hopefully mag work out yung plan ko gawing green energy source yung garden area ko. And I will use solar panel as a roof para hindi na masira ang house roof tamang tama to sa Summer kahit naka bukas lahat ng AC

[rollyic]

last time i went to raon, daming nag ooffer ng solar power.

[crosswind]

Magkano naba solar panel ngayon
correct me if I'm wrong 600k
pwede na sa isang bahay with appliances
tapos battery life is 2-5yrs
guarranteed lifetime is 25yrs
and maintenance linis-linis

on that range nga ang qoute sakin ng contractor pero may mga additional pa ko kaya di pa kami nakaka pag final deal

What I meant sir was kung yung datacenter mo yung gusto mo ipower sir and just a % of it, it really needs your time in that you need to identify which appliances/loads (eg .computer, etc). ang gagamit ng solar panel. Ang pinaka cost effective way kasi jan talaga sir, decrease mo yung load requirements mo. Then plan out yung usage times nila. May araw ba during that time? Kasi kung gabi, sa batteries ka mag depend. Ang mga pinakamahal na components kasi sir yung panels and yung batteries. Tapos yung batteries ang maiksi ang lifespan. a few thousand charge and discharge cycles if they're good quality.

[sbayhon]

I suggest that the guys you pick are conscientious in that they really measure your load needs, etc. and not just rely on you saying you need this x amount of power.

Tama si sir crosswind, yung batteries ang maiksi ang life sa mga yan kasi maswerte ka na kung may 1000+ yung charge discharge cycle ng batteries mo. I suggest yung mga lithium iron batteries, pricier pero mas sulit lalo na sa lifespan nya and sa % loss ng power/ charge.

[yebo]

meron company na sila magsho-shoulder ng installation cost tapos ibebenta nila sa iyo yung electricity, then after 25 years sa iyo na yung system. pero may minimum roof area sila para sulit bayad, di ko lang sure ilan.
