When the solar panel of the iMETOS is exposed to the sun and it gets enough sunlight it should recharge
the lead acid battery of the system constantly. With this the system should have enough power for years.
The lifespan of the lead acid battery can be expected to be 5 to 6 years with sufficient reloading from the
solar panel. Insufficient reloading will shorten the lifetime of the battery. In case of insufficient reloading
of the battery the system will reduce the frequency of data upload to the amount which is needed to
make sure that no data will be missed on the server. With this, power use will be reduced, and battery
power will last longer.

The maintenance needed for the sensors depends on the different sensors. Temperature sensors will not
need any maintenance for their lifetime whereas the rain gauge will only work properly when it is
cleaned periodically.
