Grid-Tied vs. Hybrid Solar: What's the Difference, and Which One Fits Your Home?
Grid-tied vs. hybrid solar comes down to two things: whether your system has a battery, and what happens when the grid goes down.
A grid-tied solar system is the simpler setup, with no battery. A hybrid solar system adds a battery and can keep selected appliances running during a brownout. Which one fits depends on what a power interruption costs you, not on which system is "better." If you are comparing solar panel systems for your home in the Philippines, this is one of the first decisions to make.
A grid-tied solar system is the simpler setup, but it shuts off during a brownout
A grid-tied solar system, also called an on-grid system, connects your solar panels to your home's electrical system and to the grid. There is no battery.
A typical day looks like this:
- Daytime: Your panels generate electricity, and your home uses it first.
- Nighttime and cloudy days: Your home draws from the grid, the same as before you had solar.
Without a battery to buy and install, a grid-tied system has the lower upfront cost. Our smallest system, 5 kWp, is grid-tied and needs 25 to 30 sqm of clear roof space. See our Solar Panel Philippines guide for how much roof space a 5 kWp system needs.
The trade-off is brownouts. Grid-tied systems shut off automatically when the grid goes down, so they will not keep your lights on during an outage.
A hybrid solar system adds a battery, so selected appliances stay on during a brownout
A hybrid solar system has the same panels and grid connection, plus a solar battery and a hybrid inverter. The inverter manages power between your panels, your battery, and the grid.
With a hybrid setup:
- Your home still uses solar power first during the day.
- Extra power can be stored in the battery.
- At night, your home can draw from the battery before the grid.
- During a brownout, the system can automatically switch to battery backup for the appliances connected to it.
Backup covers selected appliances, and only for as long as the battery lasts. The added equipment means a higher upfront cost. In exchange, the solar your home does not use during the day is stored instead of going to waste, so it is still working for you after dark.
The two systems differ on battery, upfront cost, and brownout backup
The right solar system depends on the problem you are solving
Choose a grid-tied system if you want the lower upfront cost and brownouts in your area are rare or short.
Consider a hybrid system if brownouts are frequent in your area, or if you work from home and need certain appliances running during an outage.
A household with a reliable grid connection may never need a battery. A home-based business in an area with frequent brownouts may value the backup.
Three things help you decide: how often the power goes out where you live, which appliances you need to keep running, and how much you want to invest upfront.
The short version
- Grid-tied solar system: no battery, lower upfront cost, shuts off during a brownout.
- Hybrid solar system: adds a battery and hybrid inverter, higher upfront cost, keeps selected appliances running during a brownout.
- Neither is universally better. For solar energy in the Philippines, the right system matches your household's needs and budget.
