Chapter 808: Chapter 807: A Set of Storage Batteries
The old lady gave him a sidelong glance: “Eat if you want, don’t if you don’t. You’re all grown up and still acting like a child, jealous of Zhiyuan. Zhiyuan is going to Xiangcheng, taking trains and planes. How can he manage without eating well? You just stay home every day; be content if there’s something to eat, let alone pure meat-filled pancakes.”
“Fine, I can’t win with you. I’ll shut up and eat, alright?” Jiang Changhai ‘viciously’ took a bite of the pancake, chewing with his cheeks puffed up.
Zhang Guihua won the banter and gave her son a proud glance.
She suddenly thought of her dad’s upcoming birthday and, looking at Jiang Mianmian who was enjoying her meal, said: “Mianmian, in a few days it’s your great-grandfather’s birthday. Go with me to celebrate it at Great Grandma’s house.”
Upon hearing this, Jiang Mianmian looked a bit troubled as she said to the old lady: “Grandma, I can’t. I’m really busy studying now. The high school entrance exams are coming up, and I need to study at home, so I can’t go to Great Grandma’s house with you.”
Even though the family had visitors and the New Year was being celebrated, she maximized her study time every day, learning solar energy technology, and at night, she would study in the system until she was too tired and fell asleep.
With so much effort over this extended period, she had reached the final stage of her studies, and at this crucial moment, she didn’t want to waste a minute.
A trip to Great Grandma’s would cost her at least two days.
Once Zhang Guihua heard that Jiang Mianmian needed to study and didn’t have time, she didn’t insist. After all, academics should be prioritized.
“Yes, Mianmian, you’re in your third year of junior high, and at this stage, academics should come first. You stay home and study well, and I’ll take Zhiwen and Zhiwu instead.”
“Alright, Grandma, you’re the best. I’ll go with you next time.” Jiang Mianmian cheerfully coaxed the old lady. ᴛʜɪs ᴄʜᴀᴘᴛᴇʀ ɪs ᴜᴘᴅᴀᴛᴇ ʙʏ 𝗻𝗼𝘃𝗲𝗹✶𝗳𝗶𝗿𝗲✶𝗻𝗲𝘁
“Okay, then I’ll be looking forward to that.” The old lady was never really upset with Jiang Mianmian. Seeing her granddaughter coaxing her like that, she immediately beamed.
Before they knew it, Old Master Zhang’s birthday had arrived. That morning, the old lady, carrying high-end gifts and with her two grandsons in tow, happily returned to her maternal home.
And that very evening, Jiang Mianmian finally finished studying all the materials the system provided and could open the laboratory to begin experimenting with making solar panels.
The system was well-prepared, with all the necessary materials and tools available. She followed the notes in her notebook, exploring and experimenting step by step.
Once she entered the system, the first thing she made was a set of batteries.
Since solar panels need to convert sunlight into electricity, she needed a set of batteries to store the converted energy.
She had previously made rechargeable lithium batteries, so making a battery now wasn’t difficult for her.
After spending half the night, she produced a battery with enough capacity, then began making the components needed for the solar panel.
These included tempered glass with a light transmittance of over ninety-one percent, EVA, battery cells, back plates, junction boxes, and so on.
After a sleep in the system, she woke up and continued experimenting.
In reality, she had tinkered for almost the entire night, equivalent to over twenty system hours, and had barely made two items.
And even with these two items, she was unsure whether they were suitable for solar charging panels.
Emerging from the system, daylight had already broken. She dressed and sat on the kang, letting out a soft sigh.
It seemed that not only was solar energy technology complicated and obscure to learn, but even making it was incredibly complex and challenging.
