Installation of solar panels using drones

Solar panels, which convert the sunlight into usable energy are the new rave by nature lovers and environmentalists. These are the most cost-effective way of getting solar energy for industrial as well as household purposes. Installation of the panels has been deemed as a lucrative business as it gives huge profits with minimal investment and manpower.
My idea is to develop a system for installing household solar panels, by using drones to control and lift the panels and all of the equipment up to the roofs, where they are going to be mounted. The most commonly used solar panels for residential and commercial applications weigh 24.73 kilograms. With regards to their dimensions, the solar panel surface area is 2.22 square meters or 23.87 square feet on average. That means solar modules will add 11.16 kilograms per square meter, or 2.29 psf (pounds per square foot) when installed on the roof. That being said, the system will require usage of some of the most powerful drones ever made.
After doing a research, the best drone for heavy-lifting tasks is Vulcan UAV Airlift. Airlift series is one of Vulcan's heaviest lifting drones to date. With the ability to lift and move a payload of about 30 kg, this drone has a tough, and durable frame that allows it to display such extraordinary strength and grace. Its central core is made of transparent tubes which allow users to easily check in on the power systems, while also making sure that all vitals are protected, which makes the Vulcan UAV Airlift the ideal machine for working in rugged environments.
The usage of solar power is widespread all over the world. People are installing solar panels on every roof. Even the car industry starts using the solar panels as parts of some vehicles, which run only on solar power. But we are mostly interested in the household usage of solar panels. The market for this kind of business idea is every part of the world, mostly developed countries, where people can afford the cost of this kind of installation and buying the whole system.
The main revenue generation mechanism would be signing contracts with the companies that install solar panels, as working partners in the business, helping the workers only with lifting every load to the roofs. The idea is to create a company that can work with every other solar-installation company, so that we can be part of every possible solar panel installation procedure.
That would require employing the most experienced team imaginable. The team will consist experts, trained heavy-lifting drone drivers, with a certain license for the job. Also, drones can be counted as team members, so the company will provide a drone park of several heavylifting drones, ones for smaller loads, and ones for bigger loads. Sometimes teaming up several drones as one may be an option.
This idea is unique because of the fact that no one has ever done it. Every company uses cranes and similar equipment to lift the panels and all of the other parts. But in some areas, a crane simply cannot be mounted. So, you call a drone company, that comes to the site, and lifts everything for you.
