On-grid vs hybrid solar: which one suits your home?
Batteries sound reassuring, but they only pay for themselves in specific situations. Here is how to decide honestly.
An on-grid system exports surplus daytime generation to the grid and draws back at night, with net metering keeping the score. It is the cheapest per unit and the right choice for most urban homes with reasonably reliable supply.
A hybrid system adds a battery so essential loads stay alive during a cut. It costs 35% to 60% more depending on battery size, and lithium packs are warranted for a defined cycle count rather than a flat 25 years.
Our rule of thumb: if you face more than two hours of outage on a typical day, or you run medical or work-critical equipment, size a small hybrid backup for essential circuits only. Everyone else gets a better return from a larger on-grid array.
