How to make your own home solar. With Pictures + solar book

[duploader]

walang problema sa ref... mas maganda pa sa ref dahil regular ang tagbo nya! But I'm not sure you will save a lot by running it 15 mins every hours! Anyway just try you will see! Dapat 2 door ref kasi....it's really a money and energy saver with a 2 door ref!!

Meron kami 2 door ref kaya lang 2x na nasira ang compressor. Mahal pagawa kaya stick ako dito sa 1 door. nwei tnx po sa info

Green storage for green energy
Published, Sept. 24, 2015

Cambridge, Mass. – September 24, 2015 – A team of Harvard scientists and engineers has demonstrated a new "Flow battery", a rechargeable battery that could make storage of electricity from intermittent energy sources like solar and wind safe and cost-effective for both residential and commercial use.

At the heart of flow batteries is a sandwich of electrodes, known as a stack, separated by an ion-conducting membrane. The electrolytes are pumped through the stack during charging and discharging. In most designs, when the battery is discharged to provide power, a positively charged electrode strips electrons from molecules in one electrolyte and sends them through a circuit to charge-accepting molecules in the second electrolyte. This process produces positively charged ions in the first electrolyte that travel through the membrane into the second electrolyte, where they balance the charges coming in from the electrons. When the battery is charged, the flow of electrolytes, electrons, and ions is reversed and electrons are dumped into the first electrolyte.

The alkaline flow battery used organic compounds called quinones as the electron-storing components of one of its two electrolytes. Quinones are abundant, naturally occurring chemicals that are integral to biological processes like photosynthesis and cellular respiration. While quinones in aqueous solution formed the negative electrolyte side of the battery, the positive side relied on a non-toxic and non-corrosive ion called ferrocyanide. All told, the battery contains only compounds made from inexpensive elements (carbon, oxygen, nitrogen, hydrogen, iron and potassium) dissolved in water. The researchers point out that because the quinone-ferricyanide battery liquids are not corrosive, they could save money on battery materials for tanks or casings, because it now becomes within the realm of possibility to use inexpensive plastics.

Battery experts see its merit. “It’s scalable, it’s inherently safe” and potentially cheap, They expect it could be commercialized soon, within a decade, but it still needs more testing.

To see how a flow battery works, see the video below.

Hello! buhay pa ba tong thread?.. hehe

Gusto ko na sana magsetup ng solar panel, since no0b lang ako sa ganito, eto muna ang balak ko; Pa correct na din kung tama ba pagkakaintindi ko.

Lahat eto CDRKing since un lang nagbebenta dito ng panels;

1x 100W Solar Panel -> higher watts means higher Ah output -> faster charging ng battery, tama ba?
1x 100Ah Battery -> higher Ah means higher storage/capacity
1x 500W Power inverter -> pwede na ba to? di ko pa kase afford yung 1000w/pure sine wave inverter -> higher watts means kaya nya ang higher ac loads na < 500w diba?.. tama ba?..

Sa charge controller and di ko alam kung anu ang bibilhin ko, kase di ko alam kung alin ba sa specs nun ang titignan ko; (need ko)

What about wires? at other items na need ko?..
any suggestions?..

Thanks,

sir jhai_salvador...

Lahat eto CDRKing since un lang nagbebenta dito ng panels;

"1x 100W Solar Panel -> higher watts means higher Ah output -> faster charging ng battery, tama ba?"
Comment: dalawang klase ang solar panels... battery panel (12V & 24V) at grid-tie panel (higher wattage panels design for grid-tie setup and MPPT charge controller)

"1x 100Ah Battery -> higher Ah means higher storage/capacity"
Comment: consider only the deep cycle battery for solar use... mas mabilis bumaba ang capacity ng car battery... pwede gamitin pero hindi sulit.

"1x 500W Power inverter -> pwede na ba to? di ko pa kase afford yung 1000w/pure sine wave inverter -> higher watts means kaya nya ang higher ac loads na < 500w diba?.. tama ba?.."
Comment: correct

2. http://www.cdrking.com/index.php?mod...d=18416&main=1
Comment: mas OK ang user feedback ng no.2... consider also higher rated charge controller like the cdr king CHR-S030-LYE (CM50)... preparasyon sa future upgrades... nakaka-addict daw kasi ang solar.

"What about wires?"

"at other items na need ko?.."
karamihan sa amin dito ay gumagamit ng 12V DC led bulb, DC fan at USB car charger adapter 1A & 2.1A

 

[jhai_salvador]

@TristanWS salamat sa reply

yung sa 100w solar panel eto un eh: 12v to diba?
http://www.cdrking.com/index.php?mod=products&type=view&sid=21244&main=1

Eto naman ung battery 100Ah:
http://www.cdrking.com/index.php?mod=products&type=view&sid=21474&main=167

Anu ba ang tinitignan sa charge controller? like for this example:

CHR-S028-LYE - (LS1024R)
Solar Charger Controller

Nominal System Voltage: 12VDC/24VDC Auto work
Nominal charge/discharge current: 10A
Max. Solar Input Voltage: 50VDC
Battery Voltage Range: 6 – 36 Volts
Self-consumption: ≤6mA
Charging Circuit Voltage Drop: ≤0.26V
Discharge Circuit Voltage Drop: ≤0.15V
Terminal: Panel/Battery/Lamp(12V)

Kelangan ba nakamatch yung charge controller ko sa solar panel/battery? how?..

Thanks,

You understood well... and Tristan already answered you but I just want to add:

What do you plan to run on solar? because all the components you are going to buy depend on what appliances you want to run... It's different if you want to use solar just for few bubs or for a tv + fan + laptop + lights... Of course you can always upgrade but the best is to have the maximum first and to try to plan in advance.
The inverter wattage will depend on the appliance you will run... if it's for lights or fan only is better to have them in 12 volts and avoid the inverter
The controller will depend on the wattage of the panel... for a 100 watt panel, a 10 amp controller is ok
The battery is the main component and the most expensive, don't hesitate to over calculate its Ah... for example if you plan to use 50 Ah per day you must have a 100 Ah bat minimum and better pa 150 Ah!
The wiring should be minimum #10 or 8
don't forget that you need to have your panel grounded
you need a dc breaker or fuse
you should have also a digital multimeter

Did you consider not using a controller? It's possible and cheaper if you can check time to time, with a digital multimeter the charge of the battery

... eto ang specs na need mo sa solar panel:
Optimum Operating Voltage (Vmp): 18.5v
Short-circuit current(Isc): 6.20A
Optimum Operating Current (Imp): 5.40A

... eto naman sa CHR-S028-LYE - (LS1024R) Solar Charger Controller
Nominal System Voltage: 12VDC/24VDC Auto work
Nominal charge/discharge current: 10A

... meaning, magpro-produce ang panel ng 5.4A to 6.2A... therefore you need a charge controller with a rated current of more than 6.2A... pwede na ang CHR-S028-LYE - (LS1024R) kasi 10A sya... however kung mag-a-add ka ng panel for more power, need mo ulit ng mas mataas na charge controller, kaya mas maige kung preparasyon ka na para hindi ka na bibili ulit.

Di rin biro expenses, kelangan talaga ng pundo para rito..

Di rin biro expenses, kelangan talaga ng pundo para rito..

under 15K may 100w panel at 100Ah battery kana. pwede for backup power yan or kahit pambawas lang sa bill ng kuryente mu.. hehe..

 

[awinahe]

Thanks, so ung 'for a 100 watt panel, a 10 amp controller is ok' san nyo po binase ung 10am controller?

10 amps is a minimum, actually bigger is better especially if you plan to add more panels
here is a small pdf file "How to Size a Solar Charge Controllers" to help you... also, if you can afford it, a MPPT controller is better than a PMW one.

okay na ako sa sizing ng charge controller.

Panu naman po ung fuse? or maybe breaker..? (di ako sigurado)

 

[josepepe]

ano pong example ng set up mabuting gamitin ang PMW o MPPT. ang ibig ko pong sabihin ay ilang solar panel at anong watts ang bagay sa PMW O MPPT.

maganda ang pagka-explain dito... https://www.windynation.com/jzv/inf/how-properly-fuse-solar-pv-system

ano pong example ng set up mabuting gamitin ang PMW o MPPT. ang ibig ko pong sabihin ay ilang solar panel at anong watts ang bagay sa PMW O MPPT.

basing on experience at sabi rin dito... http://solarcraft.net/articles/comparing-pwm-and-mppt-charge-controllers/ ... kapag 200W pataas na ang total watts ng setup, pansin na ang benefit ng MPPT scc... kapag maliit lang ang setup, hindi sulit ang MPPT... for grid-tie panels obligado na MPPT scc ang gamitin.

Real world test result here, dated 2/19/2015: http://www.solarpaneltalk.com/showthread.php?19863-is-mppt-worth-it

120W panel, Optimum Operating Voltage (Vmp): 21v
when connected to PWM = 7A
when connected to MPPT =6A

240W panel, Optimum Operating Voltage (Vmp): 34v
when connected to PWM = 7A
when connected to MPPT =12A

Conclusion: "MPPT needs high voltage panels"... (example of high voltage panels are those being used for Grid-tied setup with Optimum Operating Voltage (Vmp) of more than 36v.

Nice share. I'm wondering, why did they only use a 1W solar panel for the 12V battery? I think it will take ages to charge the battery.

 

[TristanWS]

Nice share. I'm wondering, why did they only use a 1W solar panel for the 12V battery? I think it will take ages to charge the battery.

here is my computation:

6 white 5mm LEDs in series= 2V x 6 x 20mA = 0.3 watts x 12 hrs used = 3.6 watt-hr

recharging time (sun hour) = 3.6 w-hr / 1watt panel / 0.67 losses = 5.3 hours is needed to recharge the 7.2AH battery

conclusion: i think it will work... and basing on the pictures from the link, the light generated is comparable to a small flashlight.

Nice share. I'm wondering, why did they only use a 1W solar panel for the 12V battery? I think it will take ages to charge the battery.

It will work because they don't use controller but a 2 or 3 watt panel, I think, is better to be sure that the bat will be charged in rainy season!

here is my computation:

6 white 5mm LEDs in series= 2V x 6 x 20mA = 0.3 watts x 12 hrs used = 3.6 watt-hr

recharging time (sun hour) = 3.6 w-hr / 1watt panel / 0.67 losses = 5.3 hours is needed to recharge the 7.2AH battery

conclusion: i think it will work... and basing on the pictures from the link, the light generated is comparable to a small flashlight.

I think the light generated is a lot more than a small flashlight because of the water in the bottle. On the pic, the bottle is on a table so you cannot see how really bright it is... I already made a similar experiment last year and even with a very small bulb, the light is bright talaga when it passes thru the water as the water acts like a magnifying glass.
