Why Solar Installation Is More Important Than Equipment
Think of it like this:
👉 Solar panels are just one part of the system
The installer decides:
- How panels are placed (angle & direction)
- Which solar inverter is used
- Whether a hybrid solar inverter is needed
- If lithium ion battery or lithium ion phosphate battery is suitable
- How wiring and safety systems are designed
Even small mistakes in these areas can reduce efficiency significantly.
🏠 Every Home Is Different
There is no “one-size-fits-all” solar solution.
Each home in Bangalore has:
- Different roof size
- Different sunlight exposure
