Off-Grid Solar Systems
An off-grid solar system (off-the-grid, standalone) is the obvious alternative to one that is grid-tied. For homeowners that have access to the grid, off-grid solar systems are usually out of question. Here`s why:
To ensure access to electricity at all times, off-grid solar systems require battery storage and a backup generator (if you live off-the-grid). On top of this, a battery bank typically needs to be replaced after 15 years. Batteries are complicated, expensive and decrease overall system efficiency. 
Advantages of Off-Grid Solar Systems
1. You become completely independent from external energy supplies
2. You can combine different energy sources such as PV, wind energy and hydropower
3.You can expand or change your system on a modular basis at any time
4.You can rely on our support, from planning to commissioning the system
