Frequently asked questions

What is the difference between on-grid and hybrid solar?

On-grid mainly targets daytime savings, while hybrid also includes batteries and circuit planning for backup support.

Do I need batteries to start using solar?

Not always. Many customers start with on-grid when the main goal is lower daytime electricity cost.

How should I compare proposals?

Compare system logic, scope, safety, permit work, and warranty terms before comparing price alone.

Can foreign homeowners or business owners in Chiang Mai request a site review?

Yes. The English pages are intended to help expats, homeowners, hotel operators, and business owners understand the service options before contacting the team.
