No. SolarView is very efficient and compact software that will have little to no detectable impact on your computer operation, even if you leave the desktop app running at all times. SolarView consumes very little memory, disk space, and processing resources.
Be aware that SolarView is highly dependent on live internet access. If your internet connectivity is slow or unreliable, SolarView may lose synchronization with cloud-based servers that provide its data. If your internet is service is down, SolarView will stop working until service is restored.
