Fixed PV Solar System

Generate free electricity with our modular PV systems

Solar Hot Water

Cut your electricity demand by generating hot water by sun power only.

Portable Solar Systems

Super easy installation. Lay in the sun and plug into any outlet

3.3 kW PV system
5KW PV system

PV Cost Effectiveness

System cost design optimization

By designing our systems to supplement grid electricity (rather than replace it), we are able to eliminate the most expensive componenents (battery back up). The system then maximizes the electrical contribution for the minimum system cost..

Solar Hot Water Cost Effectiveness

Cut electricity consumption

Passive solar hot water heaters generate hot water sufficient for 24 hour operation with zero electricity input.

Solar Radiation in Thailand

Year round good solar radiation

Thailand's geographic location, especially coastal areas) results in consistent solar radiation all year even in rainy season, yielding consistent cost savings all year. Areas in red and orange yield the best radiation, and return on solar energy production.
Compared to Europe, Thailand has twice the average solar radiation, making solar twice as effective

What if its cloudy or rainy?

Diffused and direct radiation

Even on cloudy and rainy days, there is diffused radiation. Studies show diffused radiation (cloudy/ rainy) to be up to 70% as effective as direct radiation (sunny). On average the approximate solar radiation variation is approximately 20% between rainy season and dry season
