Home Rooftop Solar Power System Installation Guide, What is the Latest Price
Summary: Nowadays the technology is so advanced that we can use solar energy to make various tools, which are widely used by people, for example, the simplest one is solar water heater. And people also developed rooftop solar panel, so do you know how much do rooftop PV panels cost and what are the sizes of rooftop PV panels? First of all, the price of rooftop photovoltaic panels is around 5-7 yuan per watt. Second, the common size is 1.5*0.8 meters, which can be customized according to needs. For specific knowledge about photovoltaic panels for energy production on roofs, let's take a closer look at the article! 1. What is the price of photovoltaic energy production panels on the roof?
If panelsSolar power generation waters are installed on the roof, solar energy resources can be effectively used to generate electricity, which can save electricity consumption. So, do you know how much photovoltaic panels on roofs cost?
At present, the market price of rooftop photovoltaic panels is about 5-7 yuan per watt (the price comes from the Internet and is for reference only. The price mainly depends on the size of the panel). system you are installing. The larger it is, the cheaper it costs per watt.
2. What are the sizes of rooftop photovoltaic power generation panels?
The main specifications of photovoltaic power generation panels are 250w, 255w, 260w, 270w, 275w, 305w, 310w, 315w, 320w. Photovoltaic solar panels generally do not have fixed specifications and are all customized by the fabricant.Too much.
Rooftop photovoltaic power generation panels are available in many sizes, the most commonly used are 1.5 x 0.8 meters and the power of a single panel is approximately 170 W. An average household costs at least 10 yuan, which can produce about 5 kilowatt hours of electricity every day. If the power is low, the size of the battery panel is relatively small; if the power is large, the battery panel size is also large.
3. How much do rooftop PV panels weigh?
In addition to component size, people often weigh the weight of rooftop PV panels. Photovoltaic panels can be heavy and lifting them onto your roof can be a challenge, especially if you're working alone. Typically a full size panel weighs between 18kg and 35kg, this varies depending on the product the manufacturer uses.
First of alld, we need to know the principles of grid-connected photovoltaic power generation systems and what equipment is needed.
1. Working principle of photovoltaic power generation system:
High-performance solar cell components are installed on the roof using brackets and are connected in series. and at the same time to form solar energy. The solar cell array absorbs sunlight and generates direct current, which is converted to alternating current for home use via the photovoltaic inverter and uploaded to the power grid.
2. System composition:
Mainly includes: photovoltaic modules, inverter, bracket, DC cable, AC cable, subsidized meter, two-way electricity meter
3. Market price:
The market price of photovoltaic systems is generally 8 to 12 yuans per watt. The cost of installing a 5 kW solar power generation system in an average household is about 40,000 to 50,000 yuan (the price of top-tier brands).
4. Income from domestic photovoltaic power generation includes three parts:
1. Earn money from subsidies: national subsidy of 0.42 yuan/kWh + province. subsidies + city and county subsidies Subsidies (slightly different depending on location), whether you use it yourself or sell it, as long as you produce electricity, you will be subsidized.
2. Save on your electricity bills: You can generate electricity for your own use without paying electricity bills, which is equivalent to saving money.
3. Earn money by selling electricity: unused electricity is sold to the state and the price of electricity is based on the price of rreference of electricity from local coal desulfurization units, about 0.56 yuan/kWh. (Electricity prices vary slightly from location to location).
5. Calculation of return on investment
Taking the Shandong category III area as an example, to install a 5KW domestic power plant, the investment will be around 40,000 yuan depending on the price of the market. It can generate an average of 20 kW/h per day and 7,300 kW/h per year. It is calculated based on 30% self-use and 70% sold to State Grid:
Subsidy income: 7,300*. 0.42 = 3,066 yuan (excluding provincial and prefecture-level subsidies)
Revenue from electricity bill savings: 7,300 * 30% * 0.52 (electricity bill 'electricity) = 1,138.8 yuan
Revenue from electricity sales: 7200*70%*0.35=1764 yuan
In total, the income of a year is: 3066+1138.8+1764=5968.8 yuan
It isIt takes almost 6 years to recover the money, and the average operating time of a photovoltaic plant is 25 years, equal to the net income of the next 19 years.
