String Inverter
Ideal for homes planning to add an EV charger or battery to the same ecosystem later
A string inverter combines DC from several panels and converts it to AC in one unit mounted somewhere accessible such as a wall or garage. Maintenance is simple with no roof access needed, making it the most common choice for homes.

Questions about going solar?
Is solar worth it? What's the payback period?
Homes with bills of 3,000 THB/month or more and daytime consumption typically pay back within 5–7 years, while the system lasts 25+ years.
What permits are needed?
Grid-connection approval from MEA/PEA and, in some cases, an ERC filing — Eggcode Solar handles all of it.
String vs micro inverter — what's the difference?
String uses one inverter and costs less; micro inverters sit under each panel, tolerate shade and allow per-panel monitoring — best for multi-orientation roofs.
Which roof types can be used?
Metal sheet, corrugated tile, concrete tile and flat concrete roofs all work; an engineer assesses the structure first.
What is covered by warranty?
Workmanship 10 years, inverter up to 5 years, panels up to 25 years and panel performance up to 30 years, per brand terms.
