No. You may only claim credit once per house. For example, if you added it on a second house it may be claimed again. On this link from energy.gov it states the credit is only for the "original installation", on the first page.

This is a mis-reading. The law has no such limitation. The document you reference says "The solar PV system is new or being used for the first time. The credit can only be claimed on the “original installation” of the solar equipment." This would mean that you can't claim the credit if you buy a house with a solar system already installed, you can only claim the credit if you are the installer. But this statement says nothing about "only once per house". If the taxpayer installs new equipment, they are eligible for the credit. New equipment can include the first original installation, installation of an expanded system, or removal of an old system and installation of a new system.
