Limitations of solar photovoltaic systems

Solar photovoltaic systems, also known as photovoltaics, referred to as photovoltaics (photovoltaics; “photo-” light, “voltaics” volts), refer to the use of photovoltaic semiconductor materials to convert solar energy into direct current electrical energy. The core of photovoltaic facilities is solar panels. At present, semiconductor materials used for power generation mainly include: single crystal silicon, polycrystalline silicon, amorphous silicon, and cadmium telluride. Since countries have been actively promoting the application of renewable energy¬†c purlin manufacturer in recent years, the development of the photovoltaic industry is very rapid.

Limitations of solar photovoltaic systems:

1.production process

The raw materials of solar panels are the same as those of computer chips. A large amount of energy, toxic and hazardous chemicals are required in mass production. Chemical substances are mainly controlled by laws and regulations at the location of the factory. Some solar plants have installed solar systems that produce solar panels using clean energy from solar systems.

2.Impact on the grid

As of December 2017, more than 31% of residents in Queensland, Australia, have rooftop solar systems with an average installed power of more than 3.5 kW (the world’s number one). However, the high solar system penetration rate also causes problems in the grid voltage. Residential areas have low electricity consumption at noon, mainly to sell electricity to power companies. Traditional power grids do not consider two-way power delivery. When the electricity in the residential area is transmitted back to the grid, the voltage will gradually rise and may exceed the range of electrical equipment. There are ways to solve this problem in scientific research, but there are various cost considerations, for example, an additional voltage control device in the medium voltage grid.

3.Impact on energy investment and electricity fee management

The problems in real life are often complicated and varied, and the reasons are complicated. The same is true for energy investment and electricity tariff management, and there is no universal use for every solution. Investment in solar energy systems may be a good option. If the local sunshine is sufficient, electricity prices are high and prices continue to rise, the government supports it financially or financially, and electricity can be sold back to power companies (Australia and Germany). Return on investment is often the main consideration for energy investment. But systematic inspection, evaluation and analysis may reveal that a comprehensive package Steel Profile Suppliers is the most appropriate under current market conditions. For example, improvements in energy efficiency through building construction, improvements in equipment operations, and investment in solar systems may provide the best return on investment for homeowners.
