Solar Home
An on-grid home solar system has 4 main parts. The power it generates is used in your home first, reducing the electricity you buy from the electricity authority during the day.
Solar Panel
Convert sunlight into DC power. Installed on your roof based on the orientation, tilt and shading our engineers survey on site. The number of panels depends on your roof area and power bill.
Inverter
Converts DC power from the panels into the AC power your home uses. Works alongside grid power in an on-grid setup: your home uses solar first and draws any shortfall from the grid as usual.
Battery · Optional
Stores surplus daytime power for use in the evening or at night. Ideal for homes that use a lot of power after work, or that need backup power for essential appliances.
Monitoring
Track the power you generate and use at home via a mobile app, backed by the company’s 24-hour Monitoring Center, which watches for faults and sends a team to inspect when needed.

You need to notify or apply to your local electricity authority and other relevant agencies. Our team handles all the paperwork for you, and we will explain the steps after the site survey.
It depends on your local electricity authority’s requirements. Our engineers will check your meter and electrical panel, then recommend the right size, or an upgrade to three-phase if needed.
It is a government measure for home solar installation. You need an electronic tax invoice (e-Tax), which we can issue. Conditions and timelines follow the latest announcement.
Our engineers inspect your roof type and condition before installation, then choose the right mounting method for each roof type. Installation work comes with a 2-year warranty.
On-grid systems stop supplying power during outages for the safety of electricity authority workers. To have power during an outage, you need to add a battery system.
Eligible cards and installment terms will be provided with your quote.
Fill in a short form and the SCAN EARTH POWER team will contact you to book a site survey, or message us on LINE and send a photo of your power bill right away.
