(1)The price of 10 kilowatt photovoltaic power generation varies depending on the region, between 40,000 and 70,000 per unit. Based on the bulk quantity, the higher the quantity required, the lower the price will be. Typically, if it's a 10 kilowatt solar panel, it can theoretically generate 10 kilowatt hours of electricity per hour. But many factors actually influence it.
(2) During the day, when the sun is shining, the electricity from the solar panels must be converted by the inverter into 200V household electricity before it can be used. There will be losses in the middle, usually 25%. at 30% loss. The average illumination in southern China is 3.5, so a 10 kW solar panel can produce 26 kilowatt hours of electricity per day. If there are 7 to 8 hours of sunlight that day, there will effectively be 60 kilowatt hours of electricity.Infodetailed information:
Advantages of photovoltaic energy production< /strong>
Use idle resources without manual labor p>
Distributed house is using your own idle resources on your roof to install photovoltaic power plants to to convert solar energy into electrical energy. As long as it is installed and connected to the grid, you can immediately earn income and benefit from national and local PV subsidies.

How to choose a home solar photovoltaic power generation system? What is the latest price for photovoltaic energy production?
100W home solar power generation system costs 1780 yuan/set. With TV, fan, lighting, mobile phone charging.
The p system150W home solar power production costs 1950 yuan/set. With TV, fan, computer, lighting, mobile phone charging.
The 300W home solar power generation system costs 3,780 yuan/set, with a TV, fan, computer and small refrigerator.
A 450W home solar power generation system costs 5,650 yuan/set, with a refrigerator, washing machine, TV, computer and fan.
The investment cost of large solar energy production systems is higher. Basically, the above types of electricity are sufficient. This is the price of an off-grid solar energy system.

When choosing a photovoltaic power generation system, you should consider the input-output ratio.
In fact, the current photovoltaic system is very unprofitable without subsidiesgovernment provisions.
Let's do a simple calculation.
Let's take the example of a 5 kW photovoltaic system. If connected to the grid, the current list price is 10 yuan/W.
The installation cost of 5KW is 50,000.00 yuan.
Based on a daily electricity production of 20 KW/h, the annual electricity production is 7,300 KW/h.
If the system has a normal lifespan of 10 years, the total electricity production is therefore approximately 73,000 kW/h.
Based on the calculation of 0.52 yuan per kilowatt hour of electricity, the total income is only 37,000.00 yuan.
In other words, the cost cannot be said for ten years.
It’s too uneconomical.
If the government subsidizes electricity by 0.40 yuan per kilowatt hour, your income over ten years will be 64,000.00 yuan.
The ten-year return is only 24%, which is too misleading.
Therefore, it is not recommendedndeed to install a solar home system.
If the government purchases electricity at a price of 1 yuan per kilowatt hour, the total income over a ten-year period is 73,000 yuan.
The total return over the ten year period is 46%.
If you insist on using it, there's nothing anyone can do.
It will be clear in about ten years if you look at how much electricity your home uses, what the average cost of that electricity is, and how much it costs you to buy electricity from the city.
