20kw off grid solar system
1.Picture:
Off-Grid Solar Systems
An off-grid solar system (off the grid, standalone) is the obvious alternative to one that is gridtied. 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.
