What do you think of when you hear "mini solar power generation at home"?The general image is to put the panels on the roof, veranda, and windows and use the generated electricity for lighting and home appliances.However, the panel of the mini solar power generation system is characterized by a portable size.For example, you can use it outdoors, such as camping and picnics.

The CO-BA-sponsored workshop "CO-BA Solar Picnic" is not only assembling a mini-solar power generation system, but also "How do you enjoy it with electricity generated?"Masahiro Nakamura, the representative director of Tsukuruba Co., Ltd., which runs Co-BA, seems to have tried a 100W mini-solar power generation system and tried variously how to use electricity generated by himself.is.

Meanwhile, he wanted various people to experience the pleasure of generating power and planned this workshop.The partner of the workshop is Fujino Electric Power, which regains electricity into his hands through the assembly workshop of the mini -solar power generation system and supports independence from large systems.On September 29, when the workshop was held, it was a refreshing autumn sunny day, and it was just a day.

A solar panel with casters created by Mr. Nakamura of Tsukuruba.It seems that the casters purchased online were remodeled.Now you can carry it smoothly.

The venue for the workshop is the CO-BA Library "CO-BA Library" in Shibuya in Shibuya operated by Tsukuruba.Books and magazines are lined up on bookshelves installed all over the wall, making it a wonderful space like a book cafe.

CO-BA Library at the venue

The instructor of Co-BA solar picnic is Naoki Yoshioka of Fujino Electric Power.We support this workshop.

Mr. Yoshioka of Fujino Electric Power

Yoshioka's profession, the instructor of the day, is a designer.He is a representative and art director of a joint company amprag, which mainly supports the power to improve society, such as NPO / NGO, with the power of design.Before he was involved in Fujino Electric Power, he was aiming for an independent way of life from a large energy system.In fact, Mr. Yoshioka made the handbook of "We Electric Power".

Against this background, Fujino Electric Power's business trip workshops nationwide were counted 109 times on September 23 this year, and the cumulative output of solar panels provided has reached about 37,000 watts.On this day, Fujino Electric Power's activities have been featured in various media, with the BS11 news program "Insideout" in this day.

Now, let's assemble!

The assembly workshop has a mini solar power generation system and a set of tools used for work, so you can go to the venue empty -handed.In addition, the instructor will carefully follow the work while explaining the roles and assembly procedures of each equipment from lectures on electricity such as "What is a voltage?"So even those who have no prior knowledge or are not confident in assembling.As the participants work while enjoying the work, they are completed.

First, let's look at the contents of the assembly kit.

・ 50W solar panel charge controller (prevention of charging and overcharging to batteries. Prevents current backflow from the battery) ・ 300W inverter (converted DC electricity into exchange so that home appliances can be used.Equipment) ・ Cigar socket distributor (with a USB terminal, can charge smartphones, etc.) ・ Battery (slowly put in electricity and take out slowly, a deep cycle battery with a deep cycle suitable for mini solar power generation. 12V 32AH/20HR)・ Connected cable

Mini solar power generation kit

The kit price is 42,800 yen.The battery needs to be replaced every 5 to 6 years ( * depends on how it is used), but the solar panel is a long -life product that has a lifespan for about 20 years.

The finished solar panel is about 30 hours for 6W LED lamps and smartphones, 12 hours for tablets, and 4 hours for small laptops.If this much electricity can be generated, it seems that it can be used in various ways.

We will assemble while helping each other

In this workshop, there are five assembly people and 12 visitors, and there are various participants, such as fathers, couples, and friends with children.The small children also participated in the assembly work, and the assembly work began in a lively atmosphere.

The assembly procedure is very simple.All you have to do is peel off the film at the tip of the cable required for the connection, or attach a metal terminal to the connection to connect the equipment.

The rough assembly procedure is as follows.

(1) Connect the solar panel and the charge controller.(2) Connect the charge controller and the battery.(3) Connect the charge controller and the cigar socket.(4) Connect the inverter and the battery.(5) Completed!

If you listen to the instructor's explanation and work while looking at the distributed instructions, even those who are not used to work can assemble in 2-3 hours.

Mr. Yoshioka, the instructor, reflects the assembly procedure to the projector, explains slowly, and checks the work status of the person who is assembled one by one.Fujino Electric Power's Tsuchiya will also follow the work of the participants carefully, so as long as it is reliable.

It will teach you carefully while showing the example of the work

There are two tools used for assembly: electric pressure pliers and electric drivers that have been prepared for electric shock.An electric pressure pliers are special pliers that can cut cables, peel off the cable, and crush metal terminals.The point of assembly work is whether this electric pressure plastic pliers can be used well.

First of all, in the assembly work, use the electric pressure pliers to remove the coating of the cable of different thickness and expose the core wire.In accordance with the thickness of the cable, the cable is inserted into the millimeting holes that are multiple in the blade of the electric pressure pliers, and the coat is removed, but at first it is not used to it, so the power is adjusted.Some people are stiff.However, as I did a few times, I got used to it and became able to make it smooth.

I think that this kind of work is better for men, and the couple of the participants handle pliers dexterously, and the wife gives instructions to her husband while listening to the explanation.There are also scenes where women lead the work.In addition, a small child helped her father to assemble, and a smiling sight was seen from beginning to end.

Looking at the assembly work, I remember somehow the class of elementary school work.I was excited and enjoyed making it myself.The fact that the participants' faces seem to be fun because they feel the joy of making something with their own hands.

Let's brew coffee with electricity generated

Take a break when the work has settled down.In order to demonstrate that the theme of the day, "If you take out the solar panel, you can do this, you can do this kind of picnic."

It is sunny on this day and the light of the sun is enough.Connect to a coffee maker and switch on.While everyone's gaze is concentrated, drip starts with the sound of a push!I stopped suddenly, but suddenly stopped.Unfortunately, the power consumption of a coffee maker was 550W, which seemed to be the cause.But this kind of happening is also a fun thing because it is electricity that we make ourselves.You will be aware of how much electric appliances you use everyday will consume, and you will notice a lot.

Unfortunately, the drip of solar power generation is here

With a coffee or soft drink in one hand, a break while eating sweets, you can look back on the first half of the work and exchange information, and you can hear chatting here and there, and it has a better atmosphere.Some of the participants want to name the solar panel, and become "Yoko -chan" as a child of the sun!

Meanwhile, in the revenge I mentioned earlier, I switched on smartphones, laptops, lighting equipment, and mini -components using electricity generated by Nakamura's solar panel.It is reliable to use such appliances at once!Expectations are expanding in the second half of the work.

In solar power generation, lighting equipment, notebook PCs, smartphones, and mini -components are turned on!

With the electricity made, it is finally lit!

Participants seemed to be used to work, and in the second half, each work was smooth.While cooperating with each other, we connect cables one after another to equipment.

If you connect the charge controller and the DC socket, it will finally light up.When the DC LED bulb is connected to the DC socket, it lights up!Seeing the LED lamp on the solar panel that the solar panel was generated by the solar panel, everyone seemed to be impressed.The cheers and applause saying "I did it!"The assembly has been successfully completed, and everyone seems to be very satisfied.Because it is a mini -solar power generation system that I made myself, I am also happy.

Depending on the idea, there are various uses!

When you ask everyone who participated how to use it ..."I want to use it for Christmas illuminations to decorate outdoors," "I want to take it to the camp," "I put it on the roof of the car and use it outdoors," "I usually use it, but use it for an emergency power supply in the event of a power outage or disaster.There are various ideas, such as "I want to bring each solar panel with my friends, call a band or DJ to do a festival", "I'm thinking about trying it out at home before using it at home."

If you bring solar panels to the office and increase the number of employees who are solar power generation, you may have a solar panel subsidy system in -house.Also, those who brought a small child said, "I think it's good for child education. I think children will be aware of electricity by using them at home."Everyone seems to be thinking a lot, and here I was excited.

The mini -solar power generation system has a slightly heavy battery, but it is a very compact device, so it is easy to carry by using casters for transportation.This is the good thing about the mini solar power generation system.Because it is small, if you devise it, you can use it in various ways and it is fun.

Mr. Nakamura of Tsukuruba wants to cover the CO-BA power supply in the future with solar power generation, and in order for CO-BA members to create a mini solar panel.I wonder if I will put a solar panel on the BA floor and get the members be interested. "The day when Co-BA electricity rises may be near.

Finally, the question corner from the participants.In the future, there was a question about how to increase the capacity.In response to this question, "Think carefully about what to use before increasing. The larger scale is after reviewing your life.Yoshioka says, if you try to use it as a self -sufficiency, use solar power to use the power you use, use solar power, or use it that matches your height, "says Yoshioka.

Use the electricity to "Jibun Goto" and use it happily while devising

Mr. Yoshioka ended this way.

How do you enjoy it after making it?The mini -solar power generation system is also a tool to enjoy life.How to use depends on your idea.Why don't you create a mini -solar power generation system and start a fun power generation life with your friends?
