Lesson Guide
Three Main System Types
Grid-Tied (On-Grid)
- Connected to Meralco/utility grid
- No batteries (usually)
- Cheapest option
- Net metering eligible
- No power during brownouts (safety shutdown)
Hybrid
- Grid + batteries combined
- Backup during brownouts
- Solar charges batteries by day
- Most popular in PH cities
- Moderate cost
Off-Grid
- Completely independent from grid
- Requires large battery bank
- Best for remote/rural areas
- Highest cost per kW
- No Meralco bill at all
Decision Guide
| Situation | Best Choice |
|---|---|
| Stable grid, want savings | Grid-Tied |
| Frequent brownouts | Hybrid |
| No grid access | Off-Grid |
| Want backup + savings | Hybrid |
Frequently Asked Questions
What is net metering?
A program where excess solar exported to the grid earns credits on your bill. Available in many PH areas via your DU.
Why does grid-tied shut off during brownouts?
Anti-islanding safety — prevents backfeeding the grid and electrocuting lineworkers.
Can I convert grid-tied to hybrid later?
Sometimes, if you planned for it. Easier to buy a hybrid inverter from the start.
Is off-grid legal in cities?
Yes, but unusual. Most urban homes prefer hybrid for grid backup flexibility.
Which is cheapest?
Grid-tied without batteries. Hybrid costs 30–50% more. Off-grid is most expensive.
Common Mistakes to Avoid
Choosing grid-tied in brownout-prone areas
You'll have zero solar during outages. Hybrid is usually worth the extra investment in PH.
Undersizing off-grid batteries
Off-grid requires 2–3 days autonomy. Don't size for just one day.
Skipping net metering paperwork
Apply early — processing can take months with some DUs.
