How long does it take to install a 20KW grid tied solar system?
As a supplier of 20KW Grid Tied Solar Systems, I often get asked about the installation time for such systems. The installation duration of a 20KW grid tied solar system can vary significantly based on several factors. In this blog post, I'll break down these factors and give you a clearer idea of how long the entire process might take.
Pre - installation Phase
Before the actual installation begins, there is a crucial pre - installation phase that involves multiple steps.
Site Assessment
The first step is a comprehensive site assessment. Our team of experts visits the installation site to evaluate its suitability for the solar system. We check the orientation of the roof or ground area where the panels will be installed. South - facing locations are generally the best in the Northern Hemisphere as they receive the most sunlight throughout the day. We also measure the available space to ensure that there is enough room to accommodate the 20KW system. This assessment usually takes about 1 - 2 days, depending on the complexity of the site. For example, if the site is a large commercial building with multiple rooftops or a complex terrain, it may take longer to conduct a thorough assessment.
Permitting
Obtaining the necessary permits is another time - consuming part of the pre - installation process. The requirements for permits vary from one region to another. In some areas, you may need a building permit, an electrical permit, and a connection permit to the grid. We work closely with local authorities to ensure that all the paperwork is in order. This process can take anywhere from 2 weeks to 2 months. Some municipalities have a streamlined permitting process, while others may have a backlog of applications, which can significantly delay the process.
Design and Engineering
Once the site assessment is complete and the permits are in progress, our design and engineering team gets to work. They create a detailed design for the 20KW grid tied solar system, taking into account the site's characteristics, the customer's energy needs, and local regulations. The design includes the layout of the solar panels, the selection of the appropriate inverters, and the wiring diagram. This phase usually takes about 1 - 2 weeks, depending on the complexity of the design.
Installation Phase
After all the pre - installation steps are completed, the actual installation of the 20KW grid tied solar system begins.
Mounting Installation
The first step in the installation process is to install the mounting structure. This is where the solar panels will be attached. For rooftop installations, the mounting brackets are securely fixed to the roof. For ground - mounted systems, the structure is built on a concrete foundation. The installation of the mounting structure for a 20KW system typically takes about 2 - 3 days. This time can vary depending on the type of mounting system and the ease of access to the installation site.
Panel Installation
Once the mounting structure is in place, the solar panels are installed. A 20KW system usually consists of around 60 - 80 solar panels, depending on the wattage of each panel. Our experienced installation team carefully places and connects the panels. This process takes about 2 - 3 days. The panels need to be installed at the correct angle and orientation to maximize sunlight absorption.
Inverter and Electrical Installation
The inverter is a crucial component of the grid tied solar system as it converts the direct current (DC) produced by the solar panels into alternating current (AC) that can be used in your home or business. Installing the inverter and connecting it to the solar panels and the electrical grid is a complex task that requires a professional electrician. This part of the installation usually takes about 1 - 2 days.
Post - installation Phase
After the physical installation is complete, there are still a few important steps to ensure that the system is working properly.
System Testing
Once the system is installed, it undergoes a series of tests. We check the electrical connections, measure the power output of the solar panels, and ensure that the inverter is functioning correctly. This testing phase takes about 1 - 2 days. If any issues are detected during the testing, our team will work to resolve them as quickly as possible.
Grid Connection
The final step is to connect the solar system to the grid. This involves coordinating with the local utility company. The utility company will inspect the system to ensure that it meets their safety and technical standards. Once approved, they will connect the system to the grid. This process can take anywhere from 1 week to 1 month, depending on the utility company's schedule and the complexity of the connection.
Overall Installation Time
Taking all these factors into account, the total time to install a 20KW grid tied solar system can range from 1.5 months to 3 months. The pre - installation phase, which includes site assessment, permitting, and design, can take up to 2 months. The installation phase, including mounting, panel, and electrical installation, usually takes about 5 - 8 days. The post - installation phase, with system testing and grid connection, can take up to 1 month.
It's important to note that these are just estimates, and the actual installation time may vary depending on various factors such as weather conditions, unforeseen site issues, and the availability of materials and labor.
