  1. For example: Photovoltaic power generation project of a farm 80KWP The project scale is 80.2kwp The annual average power generation capacity is 104,200 KWH, The average annual earnings are 148,000 yuan Total revenue in 25 years: 3.7 million yuan Return on investment time: 3.5 years Save 34.4 tons of standard coal annually The annual carbon dioxide reduction is 89.5 tons
  2. Six benefits of installing solar PHOTOVOLTAIC power generation: Solar energy is inexhaustible. The solar radiation received on the earth's surface can meet the global energy demand by 10,000 times. Installing solar photovoltaic systems on just 4% of the world's deserts could generate enough electricity to meet global demand! Solar power is safe and secure from energy crises or instability in fuel markets; Solar energy can be everywhere, power supply can be nearby, no long distance transmission, avoid the loss of long distance transmission lines; Solar energy without fuel, low operating cost; Solar power generation without moving parts, not easy to damage, simple maintenance, especially suitable for unattended use; Solar power generation will not produce any pollution, noise and other public hazards, no adverse impact on the environment, is the ideal clean energy; ◆ Solar power generation system construction cycle is short, convenient and flexible, and according to the increase and decrease of load, arbitrarily add or reduce the solar array capacity, avoid waste. Eight advantages of Industrial rooftop PV power generation: Make use of idle roofs and floors to revitalize fixed assets and increase enterprise income. industrial commercial rooftop solar pv grid system[/caption] ◆ For enterprises to save peak electricity charges (peak power generation in the daytime), surplus electricity can be sold online. Reduce the internal temperature of the factory, increase the cost of working comfort and cooling in summer. ◆ Can better fulfill the energy conservation and emission reduction targets stipulated by the government. ◆ Not limited by the distribution of resources, using the advantages of building roof safe and reliable, no noise, no pollution. ◆ Use the nearest user side access, without long-distance transportation, to avoid the loss of long-distance transmission lines. ◆ Solar power generation system construction cycle is short, energy acquisition time is short, convenient and flexible, according to the increase and decrease of load, arbitrarily add or reduce solar array, avoid waste. ◆ Good investment returns, can run for at least 25  years. No fuel, low operating cost, power generation process is not easy to produce pollution waste, is the ideal clean energy.  
  3. A solar panel has two warranties: a performance and equipment guarantee. A solar panel’s performance warranty will typically guarantee 90% production at 10 years and 80% at 25-30 years. An equipment warranty will typically guarantee 10-12 years without failing. A solar panel’s product warranty insurance covers the integrity of the panel itself and protects you against problems such as manufacturing defects, environmental issues, premature wear and tear etc. As with most warranties, a longer period is generally more advantageous to you, if you own your solar system When evaluating a solar panel warranty and its manufacturer, the two most important factors on which you should focus on are: 1. Product (or materials) warranty 2. The performance warranty As to Lingtechsolar, the warranty policy is strict and completely. Buyers can ask warranty policy paper from the sales person. And the warranty clause are along with order contract.
  4. Eliminate cell gap to increase module efficiency significantly. Comparing with 5BB, Lingtechsolar  series module uses circular ribbon, which is developed by Lingtechsoalr R&D independently to achieve the reutilization of light absorption and increase energy generation. Lets see explanation as below:
  5. Bifacial Module with Transparent Backsheet technology Up to 20% power gain depending on albedo and PV system design.
  6. The PERC cell has a passivated rear side and a laser grooving process, which significantly improves the cell efficiency. PERC: passivated Emitter and Rell Cell.
  7. Amount of electrical current,By using half-cells, the electrical current ( i ) flowing in each busbar is halved. Therefore, the amount of internal losses in a half-cut module is 1/4 of a full sized cell module. Lets see the instruction by chart as below:    
  8. The power per unit area is decided by the power of solar panel itself. For example, if a 1.6x1m solar panel is made of 240W, the average power per square meter is 150W. A 220W solar panel of the same size would average only 137.5W. As for the generating capacity per unit area, it is not only related to its own power, but also related to geographical location (illumination), installation Angle and other conditions Introduction Household solar panel is the core part of solar power generation system, the role of solar panel is to convert the sun's light energy into electric energy, output direct current into storage battery. Solar panel is one of the most important components in household solar power generation. Its conversion rate and service life are important factors to determine whether solar cell is useful or not. Module design: designed according to IEC:1215:1993 standard, 36 or 72 polycrystalline silicon solar cells are connected in series to form 12V and 24V modules. The module can be used in various household PHOTOVOLTAIC systems, independent photovoltaic power stations and grid-connected photovoltaic power stations, etc. Design principles The design of solar power supply system requires cooperation between users and professional solar technology companies. First of all, users need to provide exact usage requirements, including: (1) Electricity voltage and power to be solved; (2) Daily working hours, continuous rainy days guarantee time; (3) Whether there is backup mains power supply; (4) Regional and climatic data used in the system; (5) If it is to supply power to the equipment, it is best to provide the name, specification or technical parameters of the equipment. Due to the high one-time investment cost of solar power supply, the design should be based on the principle of economic and practical, as far as possible to reduce the investment, while some key components as far as possible to choose high-quality products, in order to prolong the working life of the whole system and improve the reliability of the system, reduce the failure rate. Principle Factors to consider in the design of domestic solar power generation: (1) Where is domestic solar power used? Solar radiation in the area; (2) the load power of the system; (3) What is the output voltage of the system, DC or AC? (4) The system needs working hours every day; (5) How much continuous power supply the system needs in rainy weather without sunlight; (6) load, pure resistance, capacitive or inductive, starting current size; (7) The number of system requirements.
