Micro-Inverter Solar
For roofs with shade, several angles, and awkward corners.
A conventional system wires panels into a string, so one shaded panel drags the whole string down with it. A micro-inverter puts a small inverter behind each panel instead. Every module then works independently, at its own maximum.
Right for you if
Your roof is broken up by a water tank, a parapet, a stairwell, a neighbouring building, or the coconut palm nobody is going to cut down. It also suits the multi-pitch tiled roofs common across Kerala, where panels end up facing several different directions.
How it works
Each panel converts to AC at the panel. Shading, soiling or a fault on one module affects only that module. And because there’s no high-voltage DC running across the roof, the fire and shock risk is lower. On a tiled residential roof that’s worth having.
What’s included
- Panel-level micro-inverters
- Per-panel monitoring, so a fault is traced to a specific module rather than a whole string
- Higher yield on partially shaded roofs
- Long inverter warranty terms
- A layout you can extend one panel at a time
The honest trade-off
Micro-inverters cost more per kW than a string inverter. On a clean, unshaded, single-plane terrace they’re usually not worth it, and we’ll say so. On a complicated roof they often generate enough extra to pay for themselves. The survey tells you which case you’re in, and we’ll show you both numbers.
Common questions
Are micro-inverters more reliable or less?
There are more units, but each one handles far less power and sits behind a single panel, so a failure takes out one module rather than the entire array. Warranty terms are typically longer than string inverters.
The practical difference is that a fault is smaller and easier to find.
Can I mix micro-inverters and a string inverter?
Yes, and sometimes that’s the right answer. Put micro-inverters on the shaded section and a string inverter on the clean plane. You get the yield where it matters without paying the premium across the whole roof.
