I spent 90,000 to install a solar photovoltaic rooftop power station, a total of 297 kilowatts, the power generation was too poor on a rainy day yesterday, only 99 degrees. When I woke up this morning, the sky outside the window was still dark, so I wasn't in the mood to go upstairs to check the power of the inverter. Today's Valentine's Day, I went shopping with my wife in the evening, I glanced at the power generation on the app, and I was shocked, today I actually sent more than 30 kilowatt-hours of electricity.
I looked at the time-sharing chart of the power generation, and the peak power generated today was only 9894 watts, which is very clear that the sun is not coming out. And today is a rainy and foggy day, drizzle for a while, and fog for a while. I estimate that it is just 11:00 p.m. to 13:00 p.m., when the sun is directly above, the clouds are a little thinner, so that the photovoltaic panels have half the power of full load on a sunny day, so they can emit 33 kilowatt-hours of electricity on a rainy day.
However, at that time, I happened to be in bed and fell asleep, and I don't know if the weather was exactly the same as my analysis based on the charts. After all, I thought that today, like yesterday, might have to send single-digit electricity.
Today's article answers a few questions raised by netizens in the past few days. Because, the one two days ago was popular, with 150,000 reads and more than 600 comments, I replied one by one, and there may be more replies, and some comments are not displayed.
The first question is how much does a PV power plant cost?
Many netizens think that the more than 3 yuan a watt I said is the ** of photovoltaic panels, but if you add other expenses, you think it is very expensive. In fact, more than 3 yuan per watt includes all the costs of photovoltaic panels, brackets, inverters, construction, and labor. Quoting the total price according to the number of watts is a common way in the field of photovoltaic construction. Therefore, I spent a total of 90,000 yuan to refer to all the costs of the entire project, and there are no other expenses. I don't know if I explain it like this, do you think the photovoltaic power station I installed is expensive or cheap?
The second question is how much money was paid back in total last year?
Some netizens think that the 8300 I wrote is 8300 kWh of electricity, and the power saving 1440 is 1440 kWh of electricity. Actually, the units of 8300 and 1440 are yuan.
Last year, my family's photovoltaic power station generated a total of more than 25,000 kilowatt-hours of electricity, of which more than 3,200 kilowatt-hours of electricity were used by my family itself, and more than 21,000 kilowatt-hours of electricity were sold to the power grid, and the settlement rate was 038 yuan, and the final settlement income is 8,300 yuan more than one loss. This part of the electricity for self-use is just the price of the third gradient, and the cost of using it is equivalent to 3 cents 8, if the electricity price of the third gradient of the power grid is 8 cents 3, the difference in this price is the income of saving electricity, 3200 (83-3.8) = 1440, which is about 1440 yuan.
Therefore, last year's comprehensive income, tax deduction is about 9,500, everyone thinks that the investment of 90,000 yuan, 10 months of electricity, back 9,500 yuan, this income is reasonable?
Also, we are photovoltaic players, not photovoltaic companies. The main thing is to spend some spare money to invest in a rooftop power station, send a video game to play, help everyone try, how long does it take to invest in photovoltaics, and what pitfalls may be encountered, as a reference for everyone. After all, a power station is tens of thousands to hundreds of thousands, which is a big investment and needs to be cautious. I'm happy to answer your questions, offer my experience, and help with the staff. However, those friends in the background who want me to help install photovoltaics, I'm sorry, I don't have this business.
Conscientious bloggers, the real power generation status is updated every day, and everyone should come and visit often when you have time!
