18.47 ~ 19.72m. According to the official website of Huinong.com, the ground height of the photovoltaic piles of the fish pond is 18.47-19.72 m. Photovoltaics, short for Solar Power System, is a photovoltaic effect that uses solar cell semiconductor materials.
Depending on your problem description, the number of guide holes cannot be determined. Normally, the number of pilot holes depends on factors such as ground conditions, the type and size of the designed support structure, etc. Therefore, you should consult a professional photovoltaic power generation system installation company or engineer to carry out site survey and design to determine the number of pilot holes and size details.
As for the price of photovoltaic supports, prices may vary depending on different regions, different manufacturers and different models of supphotovoltaic orts. Generally speaking, the price of photovoltaic supports is calculated on the basis of the price per watt. The price is generally between 0.6 yuan and 1.5 yuan. At the same time, construction costs, material costs, labor costs and other factors also need to be considered. .
In short, the installation of photovoltaic power generation systems requires professional design and construction to ensure the safe and stable operation of the system. If you want to know more about photovoltaic power generation systems, you can consult relevant professional organizations or engineers.
