  Modules Made for Extremes

Stan­dard pan­els are made for re­gions with a mod­er­ate cli­mate. All promises for per­for­mance and dura­bil­ity are based on mod­er­ate weather con­di­tions; such as those found
in Ger­many.
Many re­search com­pa­nies (e. g. IRE­SEN in Mo­rocco) have con­ducted ex­ten­sive tests with stan­dard pan­els in desert re­gions or in re­gions with tem­per­a­ture higher than those found in cen­tral Eu­rope: Most pan­els lose much of their nom­i­nal power after 10 years and only some of pan­els con­tinue to work for more than 15 years at 80% ca­pac­ity.

J. v. G. Thoma GmbH has been work­ing on a spe­cial tech­nol­ogy for very rough cli­mates for more than 7 years.

J.v.G. Revolution 6 now pro­duces and sells these spe­cial DESERT pan­els all over the world. Facts about the new DESERT pan­els from Ju­rawatt can be found here.


Better Performance & More Power when it's hot

The hot­ter the cell is, the less power comes from the panel. Be­cause we know that every watt counts, we have de­vel­oped a com­bi­na­tion mod­ule and cell that will gen­er­ate more wattage at the same nom­i­nal power.
Nor­mal PV pan­els have a tem­per­a­ture co­ef­fi­cient of about -0.45%/ per calo­rie. Our specially op­ti­mized cells im­prove this co­ef­fi­cient by roughly 15%, which leads to im­proved power gen­er­a­tion. The power ben­e­fit will in­crease with each de­gree of heat.


30% More Earnings & Long Life even in Hot Areas

A damp heat test is part of sim­u­lat­ing how a panel ages. This damp heat test in­creases the tem­per­a­ture to 85% in com­bi­na­tion with a hu­mid­ity of 85%. Doing this will age pan­els faster and sim­u­late 20 years time when the test is per­formed over 1,000 hours.
If the nor­mal tem­per­a­ture of the cell in hot areas will be 50-70 de­gree then such tests will not sim­u­late 20 years, but rather 10-15 years maybe, be­cause pan­els in hot areas will age much faster than in Ger­many.
Our panel can eas­ily sur­vive 2,000 hours in a damp heat test with­out any prob­lems. This means that, even in desert re­gions, we can guar­an­tee life­times of 20 years or more.
For ex­am­ple, if the panel will work 30% longer than a nor­mally processed panel, a huge finan­cial ad­van­tage will be cre­ated, one that is much greater than the few cents per watt, which the tech­nol­ogy might cost the end con­sumer.

Works where other Panels fail

Not only is the power ben­e­fit and the longer life­time a major ad­van­tage of Desert Tech­nol­ogy, but also the fact that these pan­els can be used in re­gions where other pan­els sim­ply will not work.
The data sheets for most pan­els avail­able on the mar­ket in­di­cate a max­i­mum tem­per­a­ture of 85°C - 90°C. This means that if the panel will be op­er­at­ing in tem­per­a­tures greater than 90°C, it will be out of spec and using it in areas where such tem­per­a­tures can be ex­pected will not be pos­si­ble, OR the per­for­mance war­ranty will im­me­di­ately be in­val­i­dated.
Even in Ger­many on hot days, cells can achieve tem­per­a­tures over 80°C.
These desert pan­els can take tem­per­a­tures up to 125°C.
