It wasn't that difficult to dig a well in Harbin, as the system screen showed that water resources were abundant about forty meters underground at this house.
So, Chen Lan decided it would be better to dig a deep well at her own home. Firstly, the water quality from a deep well was cleaner and less prone to environmental pollution. Secondly, deep well water generally contained more essential minerals for the human body. Thirdly, the water from deep wells was usually very clear and tasted exceptionally sweet and refreshing. Fourthly, the water from deep layers maintained a constant temperature year-round, being cool in the summer and warm in the winter. Most importantly, there would be no worry about the waterworks suddenly shutting off and leaving the household without water.
Most importantly, digging a deep well was more discreet and didn't take up much space, nor would it damage the original layout of the house and yard. Since the outlet of a deep well was not large, a diameter of only ten to thirty centimeters was sufficient for the wellhead. Moreover, the construction requirements were not high; Jia Yao and the other two could handle this task entirely, and then a booster pump could be used to lift the water. This way, water would be available as soon as the tap was turned on.
If, by any chance, the Harbin city area were to be fully equipped with tap water pipelines, allowing every household to use tap water supplied by the waterworks, then they would address it then.
When Chen Lan thought about using a booster pump, she immediately thought about electricity. She wondered if the voltage in Harbin at this time was 220 volts. Given the current electricity situation, it was unlikely that the voltage could support many household appliances.
Chen Lan recalled that when she was little, the light bulbs used at home were only 15 to 20 watts. Even so, the light emitted by these bulbs was only slightly brighter than an oil lamp. Despite this, the home's light bulbs would frequently fail to light up because the wiring couldn't handle the load.
Therefore, Chen Lan decided to build a photovoltaic power station at home using solar panels for electricity generation.
Furthermore, regarding photovoltaic power generation, it received strong national support in her previous life. It was a new industry, energy-saving, and environmentally friendly. Throughout the entire power generation process, there was no pollution or radiation. Solar energy was also a clean energy source that was inexhaustible.
The most crucial aspect was that photovoltaic power generation was relatively simple to install. It did not require the erection of transmission lines; all that was needed was a location with sufficient sunshine.
In the entire photovoltaic power generation system, the most important component was the photovoltaic panels. The quality of the photovoltaic panels determined the power generation capacity and the lifespan of the photovoltaic power generation system.
With this in mind, Chen Lan decided to generate her own electricity herself. She then turned her head and called Jia Hui, who was watching the well-digging with great interest by the well. Mother and daughter then went up to the roof of the third floor together.
Jia Hui, following her mother to the rooftop, was completely bewildered. She asked with great confusion, "Mom, what are we doing on the rooftop? Do we need to clean the rooftop too? I'll go downstairs and get the broom and dustpan."
Chen Lan didn't keep her in suspense. She praised, "Daughter, you're so clever. Your dad and Jia Yao are busy, so let's have you and I clean up the rooftop first, and then we'll do something big."
Upon hearing Chen Lan's words, Jia Hui felt that she could contribute to the family. She immediately became interested and asked excitedly, "Mom, tell me, after we finish cleaning, what else do we need to do?"
Chen Lan said with a smile, "First, let's clean up the top. Then, we'll lay down solar power generation panels, and we'll have our own photovoltaic power generation at home, so we can generate our own electricity for our own use. What do you think?"
Jia Hui was immediately eager to try. Then, she asked with some concern, "Mom, can we really do this, just the two of us?"
Chen Lan replied very calmly, "We two will do the preliminary preparations first. After your brother and your two younger brothers finish digging the well, we can call them up to install the power generation equipment!"
Jia Hui still asked with some unease, "Mom, this seems different from the power generation in the valley. Can the three of them really do it?"
Chen Lan looked at the area of the rooftop, calculating in her mind, and replied casually, "What's so difficult about it? They've learned and done this kind of work many times in the valley with your uncle and Teacher Zhou. This simple solar power generation is even easier. Besides, there are installation manuals. I think this should be no trouble for them at all."
Hearing Chen Lan say this, and seeing her confident demeanor, Jia Hui no longer dwelled on the question of whether they could do it. She immediately said, "Okay then! Mom, you just wait up there and rest. Leave the cleaning to your daughter. I'll go downstairs to get the broom and dustpan."
Before she finished speaking, she had already run downstairs.
The children had all grown up now, and Chen Lan felt it was time to let them learn to do things. So, she went along with Jia Hui's arrangement and would just assist her.
In fact, photovoltaic power generation is the process of converting solar energy into electrical energy. In the entire photovoltaic power generation process, the most important component is the photovoltaic panel module. In addition, brackets, inverters, and other related system accessories are also needed.
Finally, during installation, it is essential to operate strictly in accordance with the steps and requirements specified in the manual.
Therefore, Chen Lan did not hesitate. She used her mind to search for the words "photovoltaic power generation" on the system screen. After careful selection and comparison of advantages and disadvantages.
Finally, Chen Lan decided to support domestic products and chose Chinese-manufactured Tianhe photovoltaic panels. These are monocrystalline silicon solar panels, which have a high photoelectric conversion rate and are currently the most efficient in terms of photovoltaic conversion efficiency among all types of solar panel cells.
However, due to the high manufacturing cost of these photovoltaic panels, they have not yet been widely used. But this type of photovoltaic panel is very sturdy and durable, with a long service life, typically at least fifteen years, and some can even last up to twenty-five years.
Chen Lan ultimately decided to install photovoltaic panels from this manufacturer. She chose Tianhe's latest product, the second-generation Tianhe 600 photovoltaic panel, to assemble the photovoltaic power station for her home.
Because this second-generation photovoltaic panel is an upgraded version, its quality is much better than the first generation. Its frame is made of aluminum alloy, the material is very thick, and it is extremely sturdy and durable. Moreover, the component efficiency is high, and the overall cost is lower.
Chen Lan also estimated the area of the roof and planned to invest a total of 100,000 yuan to purchase 108 photovoltaic panels at once, along with various supporting facilities.
