You should hire an expert installer to install your solar energy
system. Ensure they have a qualified engineering team with technical
expertise and experience. If the installation team can provide a company
profile with organisation chart, it will be easier for you to determine the
quality of the team.
There should be a legal recognition in the country for the installation
company or developer. It is far better if it is a private limited company than
a partnership, an LLP, or a partnership firm to avoid the dispute later.
Make sure your installation company provides you with the correct GST
invoice. There is a 25-year warranty on the panel and a 10-year warranty on the
invertor. For that, you shall keep the GST invoice with you if you need to
claim the warranty. If your developers had cloud invoicing capabilities, it
would be better
A service center should be available at the installation company. It is
necessary to have a system that receives complaints through direct calls,
whatsapp messages, emails, and registrations. Also check the reviews against
the each tickets
The majority of solar developers only
sell inverters and panels from one brand. You will not be pushed for a brand
they hold if you receive an offer for a different brand from one developer.
A design including structural work and
a schematic diagram for electrical installation, provided by your installation
team, would be ideal. By doing this, you will be able to see how your solar
system will look.
