Over the next 10 years, 2021 more solar energy will be installed in the US than in all previous years of 2021. Considering that solar roof installations have achieved records in recent years, this rapid expansion should come as no surprise. .
Although a lot of people go to the sun, it can be a long process. Before you sign a contract, you need to make sure your home is in good condition, find a good solar company and gather and compare some quotes. After that, others will be responsible for authorizing, installing, and final approval of your solar panels.

While waiting may seem like a nuisance, it can affect your overall savings as quickly as your solar panels are up and running. The federal solar tax credit is slashed by the end of the year and clean metering plans are being reconsidered across the county. When you are faced with one of these deadlines, understanding how long the entire installation process takes can help you make decisions. Here’s what you need to know.
Supply chain issues and personal research
There are a couple of points that are difficult to organize in the process of buying the sun. See the article : Sparkwing solar panels selected to power Aerospacelab’s first Very High Resolution satellite.
One variable is that the current supply chain problems have not skipped the solar industry, which means that 2022 is a safer year than normal for the solar sector. To date, solar installations in homes have continued to set records, and most of the delays have affected industrial and service facilities.

Another variable is the time you spend doing your research and requesting quotes. Because the solar industry is a highly competitive residential industry, sellers are very sensitive. This step will last long enough. The pressure to quickly sign a contract can be a sign of a fraudulent business, so be careful.
Solar companies can have slightly different processes, so your experience may vary compared to what is described below. However, it will give you a good idea of how the process works in general and how long it will take.
Solar site assessment and system design
Before a solar company can install panels, they need to design a system that fits your roof. This is almost always when a solar professional visits your home for an assessment. This may interest you : How is solar energy generated from the sun ?. They need to ensure that your roof does not need to be replaced before installation and that trees or other buildings do not have too much shade. If your house needs a new roof or you need to cut down trees, your timeline will be a bit longer.
After evaluating your home, your solar contractor will design your system to suit your roof and your energy needs. You will accept the final design and sign a contract. Various experts estimate that this stage lasts from one to four weeks.
Permits and approval
Once the design of your solar system is complete, so should your city or local authorities. It depends on the process of issuing the necessary permits from the time your solar installer sends the necessary permits, which some local governments have chosen to expedite.
Estimates range from three weeks to 11 weeks. You can get an idea of how quickly permits can be taken with a map that can be clicked on the Solar TRACE tool in the National Renewable Energy Laboratory tool, even if only for areas with sufficient data to provide calculations.
It can take months from signing a contract to generating solar energy.
Installation
Perhaps the most exciting part of the solar installation process is also one of the fastest. The installation – when staff attach panels to your roof – takes just a few days, even for complicated work. It is expected to take three days or less.
Permission to operate
Once installed, you cannot turn on a switch and start using electricity from your panels. Your city should inspect the installation and make sure it is in the code. The Solar TRACE tool can give you an idea of how long it will take in some places, even if it’s a good estimate for a couple of weeks.
The last step is to get approval from your utility system, called an operating license or PTO. Since the service has a duty to provide the necessary electricity in its territory, they must approve projects that send energy to the grid.
Depending on the usability, this can vary significantly, but some calculations say that it will take three to eight weeks to install and get permission to operate.
In total, from the design of the system to the permit to operate, your solar purchase process can take anywhere from two to six months, although some set a limit of four months.
The timeline is something you want to discuss with your installer before signing a contract. While unexpected delays appear, finding out how long each step takes will help you identify irregular or unreasonable delays throughout the process. The faster you get these last permits, the faster you can start saving money.
What is NTP and cod?
NTP versus COD. Most entities that purchase solar assets (i.e., yieldcos, utilities, and independent electricity producers) prefer to acquire terminated assets on a trade transaction date (COD) against an NTP (follow-up note). This has increased the need for construction loans.
