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
