The disadvantages of cement pile single-pile photovoltaics are as follows.
1. Low energy density: Although the total energy that the sun projects onto the earth is extremely enormous, because the earth's surface is also very large and most of the earth's surface is covered by oceans, the Solar energy that can actually reach the earth's surface cannot reach the earth. The range of solar radiation energy is about 10%, resulting in less solar energy obtainable directly per unit area of land.
2. Large area: Due to the low energy density of solar energy, the photovoltaic power generation system occupies a large area.
Commonly used supports for the installation of photovoltaic power generation equipment include
Jining Xinyao Machinery Co., Ltd., Tangshan Baofeng Pipe Pile Co., Ltd. and Chengdu Hengruitai Construction Engineering Co., Ltd. Jining Xinyao Machinery Co., Ltd. was established in 2017 and deals and sells engineering machinery and accessories; electrical machinery, mining equipment and accessories, auto parts, plastic products, rubber products, standard parts, electrical equipment, steel, hardware products, office products. Sales of supplies. Power generation micro pile pile heads from Jining Xinyao Machinery Co., Ltd. are of the best quality and most cost effective. Chengdu Hengruitai Construction Engineering Co., Ltd. focuses on: developing hot spring geothermal wells; hydrogeological and geophysical studies; exploration and development of geothermal resources; and full use; development and utilization of geothermal resources; new investments in geothermal energy; exploration, designption and construction of geothermal resources, etc. Tangshan Baofeng Pipe Pile Co., Ltd. was jointly invested and established in November 2009 by Tianjin Baofeng Concrete Pile Co., Ltd. and Hong Kong Baofeng International Investment Co., Ltd.
Cast-in-place bored pile foundation, steel spiral foundation, etc. Photovoltaic mounts can improve the system's ability to withstand wind and snow loads. Proper use of the charging characteristics of the photovoltaic rack system can further optimize its size parameters, save materials, and help to further reduce the cost of the photovoltaic system. installed supports There are eight types, namely: cast-in-place bored pile foundation, steel spiral foundation, independent foundation, reinforced concrete strip foundation, precast pile foundation, drilled cast-in-place foundation, spiral pile foundation in steel and flat roofdation of photovoltaic support.
