This one is cool, father and son :D.
Sirs Jeff Ng and his father Wilson Ng, attended a solar seminar. Well the patriarch Sir Wilson accompanied his youngest son he did not participated in the solar panel DIY hands on though and just let Jeff do the task of finishing both projects.. Electronics is not their line, but they are interested in learning how solar energy works and how to conserve electricity using this kind of system.
Lecture and hands on of wiring system.
DIY hands on training, 5 watts solar panel.
Sir Jeff proud of his very own solar panel.. It was a good day for all of us. The family invited us to visit their bread store in Manila, to which we did :D.
Thank you po for coming over. Hope we shared something valuable to both of you. More power!
Yes you can do this.. and save more on your electricity bills during the holidays.
Use LED Christmas lights instead of the usual Christmas lights that you see at the malls/stores.
Here’s what you need
10 watts solar panel (or 5 watts)
5 watts 100 LED bulbs Christmas lights
50 watts inverter (or lower)
When daytime the solar panel will charge the battery. At night time the battery will power the Christmas lights, it’s that simple and the installation/wirings are very easy to do.
Here’s another guide on solar panel installation.
Solar Charge Controller - how important is this product to your solar power system.
A charge controller or solar charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and the current coming from the solar panels going to the battery. Most “12 volt” solar panels give out about 16 to 20 volts, so if there is no regulation the batteries will be overcharged and that in turn will damage your battery. Most batteries need around 14 to 14.5 volts to get fully charged.
There are times that solar charge controller are not needed if you have a small maintenance solar power system or solar panels, example are the 1 watt to 5 watts solar panels. A rough rule is that if the panel puts out about 2 watts or less for each 50… Continue reading
Believe it or not, these 2 guys are best buddies..
Sir Victor (or lolo Victor) came first about a week before the scheduled seminar to inquire, then on the day of sem he was accompanied with his best bud Sir Noriel.. wow.. Even with their huge age gap they understand each other and are good friends. They said they both wanted to learn what solar energy is all about and how it works. They prefer to do things together.
Lecture, computation and hands on wiring system…
At the hands on part, they both worked on 1 solar panel tabbing each cells alternately all the way to framing it.
Sharing the tabbing of cells…
Framing the tabbed cells…
Finished project and testing for voltage output under the sun… Their project is perfect! They didn’t even broke even a single cell :D.
Thank you, we… Continue reading
I made this one last September. I had a scrap of polycarbonate sheet left from the 200 watts solar panel I made that I hate to throw away, so I decided to use it, making a one column 5 watts solar panel.
36 pcs 52x19mm solar cells
scrap polycarbonate sheet
scrap acrylic – for backing
high temp clear spray paint
aluminum tape to seal the sides
I used the high temp clear gloss spray paint for encapsulation. The one I am using says it never fades, and whenever I redo my project i can always untab one or a few cells with no problem at all, unlike if i had used a resin or EVA to encapsulate it which is impossible to make changes on the cells.
I have been using this for my seminar during demo. Can be used to charge a gadgets,… Continue reading
Sir Lou Wright owner of Mountain Crest Elderly Care Homes in Langkaan Dasmarinas Cavite was not able to attend the scheduled seminar last October 28, due to unforeseen events. By our day available we had scheduled a seminar just for him and his two companions as he is planning on converting his place to use solar energy.
Sir Joel Codotco from Laguna who also is a busy man cannot attend the scheduled seminar, and came on the said date also to join sir Lou and his team, this was held last November 1.
Sir Lou Wright with his team Dennis and Marlon and Sir Joel Codotco
The seminar started with sir Joel first who came in very early for the set time :), so he started with the hands on as he has other plans that day but really wanted to learn how to make solar panels, when sir Lou Wright… Continue reading
Here’s one tip we’d like to share in solar panel DIY.
We’ve been getting inquiries on how to correctly tab solar cells, as they say they are having a hard time tabbing them and the cells get broken.
For a start your soldering iron should be 40 watts to 60 watts, I have both.
The tip of your soldering iron should be flat like this (click pics to view larger).
The most common soldering iron that we can buy are those with pointed tips. Flat tip is what is best to use on tabbing solar cells. Here’s a pic, comparison of the pointed tip and flat tip soldering irons.
If you cannot find a soldering iron with a flat tip, what I did to mine is I used a metal grinder to flatten the tip of my soldering iron like the one above. If you don’t have a metal grinder,… Continue reading
Another seminar was conducted last October 28, same venue at the Multipurpose Hall of Tsarina Grand Villas in Gen. Trias, Cavite.
We’ve made a few changes on the seminar, from this time on framing the project will be included in the hands on, up to the last part, installing the junction box at the back of the frame.
Sir Lito Sarmiento from Las Piñas who just dropped by to take a look attended the seminar, he had another appointment somewhere else but decided to drop by. Sir Lemuel Batrina from Antipolo reserved for the seminar 1 week before. The other attendees who reserved for their slots were not able to attend because of conflict of their schedules.
Level 1 – Lecture…
Lecture – demo and hands on of wiring (solar system)
Level 2 – Hands on…
Framing the project…
Finished projects,… Continue reading
Ever wonder how you can save gas on cooking?
Well, we’ve been using this one for more than 2 years now. Our solar powered wood/charcoal stove. We’ve been redesigning this for the nth time.. lol. Trying to make it easier on cleaning. The stove works perfectly fine using either wood or charcoal, and can cook real fast. What we are trying to do with the design of the stove is to make it look better and cleaning (removing of ashes) easier.
The stove has a blower that can be adjusted to how high or low you want the fire. The blower is powered by solar panel during daytime and solar charged deep cycle battery in the evening.
The model is our recent design, and will be changed next week :D. Pics were taken during a demo at a construction site.
Solar panel used – 5 watts only.
We used scrap… Continue reading
We conducted another one on one, this time it was with Eric Chua from Dasma who requested it, as he was not able to attend the last seminar schedule we had.
Venue of one on one is at TGV Gen. Trias, Cavite. Conducted last Oct 16, 2012.
The lecture went quick as expected since he was the only one being taught and the only one asking questions :D.
The hands on started before lunch. Before lunch he had to solder 9 solar cells first :D.
Eric has a background in electronics already and is making his own coin slot operated machines for Play Stations and cellphone charging machine, teaching him went smoothly.
Testing his finished project before framing, and adding the junction box at the back.
Sir Eric Chua with his finished project – 5 watts solar panel framed temporarily and all good to use. He is planning on making bigger… Continue reading
