Most definitely, batteries offer many benefits including storing excess solar energy for use after dark.

Businesses can also use batteries to avoid grid penalties and to participate in grid balancing events to generate additional income.

Are there different types of solar mounting?

There are three main types of mounting system, these are In-Roof - where the panels sit on frames that replace roof tiles, they look more streamlined and typically reduce the weight on your roof. On-Roof are the simplest to install on on existing roof - mounting brackets are attached to your roof structure and the system sits just above your tiles. The third option is ground-mounted, this is a great option as you'd benefit from a larger system and have the space at ground level.
