Question 1

Is installing solar panels worth it?

Accepted Answer

Installing solar panels for businesses in Thailand is highly cost-effective. You can typically save 30-50% on monthly electricity bills with a payback period of 4-7 years. The system lasts 25 years, and after payback, all savings become pure profit.

Question 2

What is the difference between PPA and EPC?

Accepted Answer

PPA (Power Purchase Agreement) requires zero upfront investment. The solar company installs and maintains the system on your property, and you simply buy electricity at a discounted rate — saving 10-30% immediately. EPC means you invest in and own the system yourself, yielding greater long-term savings but requiring an initial investment.

Question 3

How much roof space do I need for solar panels?

Accepted Answer

On average, 1 kWp of solar panels requires approximately 6-8 square meters of roof space, depending on the roof type. Flat roofs require less space than sloped roofs. CapSolar will survey and design a system suited to your specific roof.

Question 4

How much carbon does solar energy reduce?

Accepted Answer

Every 1 kWh of solar electricity produced reduces CO₂ emissions by approximately 0.5 kg. A 100 kWp solar system can reduce carbon emissions by about 60-70 tons per year — equivalent to planting over 3,000 trees.
