Farmers and those involved in the agriculture sector may find solar energy investments more attractive than ever in light of some recently announced testing from a leading solar company.

According to Suntech Power Holdings, all of its core products have been certified as maintaining a high level of performance when exposed to ammonia. The certification came from the German Institute for Standardization (DIN).

The certification is useful because it will give farmers more confidence that solar panels will work in areas with high concentrations of livestock or fertilizer and the ensuing levels of ammonia in the surrounding air.

"We are confident that this certification will make a substantial difference for consumers and investors working across agricultural industries or environments. DIN standards have been around for a long time, as they are used and respected for many different types of farm equipment," said Winfried Wahl, Product Manager for Suntech in Europe.

While a growing number of farms have been going solar, agricultural entities have been further making strides toward cleaner energy by taking advantage of technology that uses methane from livestock waste to generate electricity.
