How much electricity can be generated per day by 150 square meters of photovoltaics

First of all, you need to know what your installation address is**? What does the installed roof look like. Let's take Texas as an example to give you a brief introduction.

About 60-80 watts per square meter are installed on flat roofs, and about 120-140 watts per square meter are installed on sloped roofs. Depending on your area, the installed capacity is around 9,000-21,000 watts. So according to the annual average power generation per kilowatt-kilowatt-hour of electricity in the three types of areas in the country, your 150 square meters of electricity generation per day is about 40,500-94,500 kilowatt-hours.

150 flat-mounted photovoltaic is about 20kw, and the annual power generation in Zhejiang should be about 10,000 kWh.

Each region has different hours of sunshine and different amounts of electricity.

It's not about the area, it's about how big a kilowatt you are.

In general, the photovoltaic industry does not use the square to calculate many data of the photovoltaic power plant. Generally, it is calculated according to the installed capacity of the photovoltaic power station, and the amount of electricity generated per square hour can be determined according to the installed capacity.

Taking the commonly used monocrystalline silicon photovoltaic panels as an example, 100 square meters of roof can be installed about 10-13kw, if 10kw is installed, taking the light resource area in Zhejiang as an example, the annual power generation is about 10 * average power generation coefficient) = 11500 degrees.

The above calculations are taken as the lower threshold of the average value, and the actual power generation will be higher than this figure. From the above calculations, it can be seen that the annual effective light duration is 1500 hours. So we can draw the first conclusion that each square hour can generate about the degree of electricity.

Large-scale ground-mounted photovoltaic power station.

Since the adjustment of the subsidy for photovoltaic power plants, the cost of photovoltaic power generation has begun to decline, and the average of the current photovoltaic power station in the industry is Yuan W.

In fact, how much electricity can be generated per square meter per hour depends entirely on how much capacity photovoltaic power station can be installed per square meter.

From this, we can calculate the cost of each square meter of photovoltaic power station, taking 10kw as an example, the system price of the full package installation is about 50,000 yuan, and the installation of 10kw photovoltaic power station requires at least a roof area of about 70 square meters, so the cost of photovoltaic power station per square meter is about 50,000 70 = yuan.

Note: The cost required for different regions, different installation difficulties, different roofs, and different installation methods is slightly different. The above is a common installation method calculation.

In 10 hours, one square meter of solar panels can generate kilowatt-hours of electricity.

The power of one square meter of solar panels is 140-150W, but the power generation of solar energy is greatly affected by the sunshine, the stronger the sunshine, the longer the sunshine time, the greater the power generation, such as morning, noon, night, cloudy, rainy, etc., a day can probably produce electricity.

There are many kinds of solar panels, one is crystalline silicon material, there are two kinds of monocrystalline silicon and polycrystalline silicon, and the other is amorphous silicon power generation, that is, it is not crystalline silicon, there are thin-film solar energy, flexible solar power generation Due to the low conversion rate of amorphous, crystalline silicon solar power generation is now more widely used.

First of all, solar photovoltaic panels are not measured by square meters, and the current standard of a 500W photovoltaic panel is about 2 square meters. Secondly, how much electricity can be generated, it depends on what area you are in. Areas with good sunlight exposure have more than 2,000 hours per year, while areas with poor sunlight have more than 1,200 hours a year, so it is not surprising that the same photovoltaic power generation panel, installed in different regions, has a double power generation capacity.

Now the efficiency of photovoltaic panels in the industry is about 20%, so the power of 1 square is 200 watts.

There is a professional term in the industry: equivalent power generation time (that is, the equivalent power generation time is converted into 1000w m of irradiation), the equivalent power generation time is less than 1h on rainy days, and 7-8h on sunny days. According to the average conventional 4h calculation, 1 square photovoltaic panel generates 200W * 4H = 800Wh = kWh of electricity a day.

Generally, the power generation power of one square meter photovoltaic panel is between 100 and 120 watt-hours. That is, kilowatt-hours per hour. Then it depends on the time and intensity of the local sunshine, in the central region, in the summer, if you meet 8 hours of light, you can generate one kilowatt-hour of electricity.

1 square meter can be about 140 watts, and the power generation capacity for 4 hours a day is the kilowatt-hour of electricity.

Summary. One square photovoltaic panel can theoretically generate 200 watts per hour, and 200 5 = 1000 watts of electricity can be generated for 5 hours of sunshine a day. However, due to the weather and altitude, the power generation of each region is different, especially the power generation of high altitude and long day is higher than that of low altitude and short day.

Can you elaborate on that a little bit more?

One square photovoltaic panel can theoretically generate 200 watts per hour, and 200 5 = 1000 watts of electricity can be generated for 5 hours of sunshine a day. However, due to the weather and altitude, the power generation of each region is different, especially the power generation of high altitude and long sunshine is higher than that of Ye Ze and low altitude and short sunshine.

Summary. Under normal circumstances, each kilowatt generates about 3-4 kilowatts per day on average in North China, which is about 1 square meter of electricity per day, which is about 110 146 kilowatts a year.

Wait a minute. Under normal circumstances, the average daily power generation per kilowatt in North China is about 3-4 kWh, which is about 1 square meter of average pure letter per day, and about 110 146 kWh of electricity in a year.

How much does it cost to buy photovoltaic panels per square meter.

Buy photovoltaic panels per square meter at 150 yuan.

How much does it cost per kilowatt-hour sold to the national grid?

This ** is not sure, the State Grid has a special manufacturer, and will not find other businesses casually.

Summary. 1 square photovoltaic power panel, ***, the maximum power of 140 watts, per hour, calculated according to 8 hours of sunlight a day, about a day of power generation.

1 square photovoltaic suspect Huifa ant electric panel, ***, the maximum response rate of 140 watts, per hour, calculated according to 8 hours of sunlight a day, about a day of power generation.

How much does 100 square meters buy a year.

100 square meters can produce 40,150 kilowatt-hours of electricity a year.

An area of 60 roof, can be installed about 8kw photovoltaic modules, according to the installation plan of the carbon silver imitation Min large company, the current power station terminal sales ** 4 yuan w (including photovoltaic modules, inverters, distribution boxes, brackets and other equipment), a 60 power station investment needs 10,000 yuan. (It is emphasized here that this cost calculation is calculated according to the average market price of photovoltaic modules in 2020), that is, 533 yuan for Nachang.

The benchmark electricity price for power generation is yuan for one year (Zhejiang Province as an example in 2020), and the state subsidy for 20 years is 8 cents per kWh. The comprehensive income of one year is 5,898 yuan, and it takes years for the power station to recover the cost. This income is calculated according to the model of "self-consumption and surplus electricity on the grid".

40% for self-use, 60% on the Chang network. In other words, the installation of an 8kw power station requires an annual recovery of costs. After the cost is recovered, the income of the power station will be there, and all of them will be owned by the owner, and the service life of the power station will be about 25 years.

The yield of the power plant can reach 13%-18%. Specifically, depending on the proportion of self-consumption of power generation, the higher the proportion of self-use, the higher the comprehensive rate of return.
