In the past ten years, as the most concerned new energy type, photovoltaic technology has made leaps and bounds in development, photovoltaic conversion efficiency continues to improve, KWH cost has declined rapidly, the future photovoltaic will become the most competitive form of energy, 1. Renewable energy development trend Global Energy Outlook: By 2050 renewable energy will account for 79% of the global power structure By 2050, photovoltaic will account for 33% of the global power structure, wind power will account for 29%, and fossil energy will fall to 18%.
The cost of KWH electricity has been continuously reduced, and the installed scale has continued to increase.
Over the past decade, the cost of photovoltaic power generation has fallen significantly relative to the cost of other power generation technologies, and by 2035 and 2050, the cost of power generation will be 50% and 70% lower than today.
In the past three years, the cost of photovoltaic power generation has fallen by nearly 40%, compared with only 10% for wind power, and the cost will continue to fall in the future as technology continues to improve, but the speed will gradually slow down.
Photovoltaic will become one of the most competitive forms of energy in the future.
Solar energy is the most abundant energy that human beings can use, and the energy that solar energy shines on the surface of the earth in one day is enough for human beings to use the current energy consumption for 25 years, which is inexhaustible.
Photovoltaic is a kind of clean energy, the development and utilization will not cause pollution and public hazards, but will not affect the ecological balance, is a direct application of photovoltaic, but also can repair the ecology.
The distribution of solar energy is relatively balanced, no matter where on the earth there is sunlight, can be developed and used on the spot, the future photovoltaic in most countries and regions in the world will become the cheapest local power energy.
2. Innovative application in multiple scenarios
Large ground intelligent photovoltaic
(1) By using AI BOOST intelligent tracking bracket control algorithm, actively avoid shadow occlusion in the morning and evening anti-tracking stage, digital fusion, neural network self-learning;
(2) AI BOOST intelligent IV diagnosis, one-click online full inspection, does not affect power generation, automatic collection, can identify 14 kinds of faults, greatly improve operation and maintenance efficiency, reduce operation and maintenance costs;
(3) Intelligent photovoltaic grid-connected algorithm effectively supports stable operation in the whole scene power grid environment, supports SCR=1.5 on the machine side under weak current network, and active harmonic suppression THDi < 1%.
Industrial and commercial intelligent photovoltaic
At night, when the PV module is not working, a biased DC voltage is applied between the inverter PV- and the ground, which will increase the voltage to the ground of the string PV-, and the positive voltage is between the negative electrode of the module and the border. The sodium ions that migrate into the components during the day are returned, thereby restoring some of the power generation capacity lost due to the PID effect.
Household smart photovoltaic
(1) Network intelligent analysis of arc characteristics, accurate detection, no false positives, confirm the arc 0.5s fast cut off circuit to ensure system safety.
(2) Component-level power generation unit replacement group cascade, up to increase household system power generation 30%, each component independent power generation, do not affect each other.
Energy storage systems will account for a higher proportion of the market in photovoltaic power systems in the next few years.
Through the combination of photovoltaic and pumped storage in some places with rich light resources and a gap near the sea, the industry chain model of photovoltaic manufacturing is completely driven by photovoltaic electricity.
The popularity of electric vehicles is very beneficial to the regulation and balance of electric energy. Theoretically speaking, the energy storage function of electric vehicles alone can regulate the power balance.
Renewable energy to produce hydrogen, further enhance the absorption capacity
(1) It is of great significance in terms of cost, environmental protection, emission reduction, and energy security, and the proportion is expected to reach 70% in 2050;
(2) Off-grid solution, reduce the cost of lifting/buck, rectification and grid-connected equipment, saving 40% of the system cost;
(3) Support and/off-grid multi-mode hybrid hydrogen production, photovoltaic hydrogen production during the day, night valley electricity hydrogen production.
