FAQ

What size solar system does a home need?

Choose based on your bill and daytime use. Homes with bills of 2,000–3,000 baht a month usually suit 3 kW, 3,000–5,000 baht suits 5 kW, and over 8,000 baht or homes with an EV usually suit 10 kW and up

How much does each solar system size cost?

About 90,000–130,000 baht for 3 kW, about 150,000–210,000 baht for 5 kW and about 280,000–380,000 baht for 10 kW, including equipment and installation labor. The final price is confirmed after a site survey

How many days does solar installation take?

A typical home rooftop installation takes about 1–3 days, but the overall project timeline also includes the utility permit and meter replacement steps

What kinds of roofs can take solar?

Metal sheet, double-roman tile, CPAC tile and concrete flat roofs are all suitable — we choose mounting brackets to match the roof material and check the structure's load capacity before installation

Can I use power during an outage once I have solar?

Standard on-grid systems shut down with the grid for the safety of utility workers. To keep power during outages you need to add a battery and backup circuit, which can provide about 4–12 hours of backup depending on battery size

How long do solar panels last?

Solar panels last more than 20 years and come with a manufacturer's output warranty. Inverters have a shorter life and should be planned for replacement according to their warranty period

Do I need permission to install solar?

You need to apply to connect the system to the utility (PEA or MEA) and notify building modifications depending on system size. Our team handles all the paperwork and coordination
