Solar Panel Installations Over Time

Kilowatt hours kwh are a measure of total electrical energy used or produced over a period of time.

Solar panel installations over time.

The great thing is that most solar companies will back up their products with a 25 year warranty or efficiency guarantee meaning that this isn t just a sales pitch to get you on the hook. One additional factor that can add time to your installation process is putting in a power meter for net metering. Solar panels lose efficiency over time so they ll probably be down to about 80 of their original efficiency once they reach a quarter of a century. The very first solar cells invented in the 1800s were less than one percent efficient not nearly enough to make them a useful energy source.

The timeline for the installation will range from one to three days completely dependent on the size of the system you are installing.
