If you are interested in saving money and completing a solar project, you can get an individual PV mounting system from PIKESTEC. The cost is far less obviously than what you would pay to hire a solar EPC installer.
You can treat the solar installation process as a semi-DIY project, buy the system or components with highest-quality items to have innovative work.
