The top solar panel for hot climates is the SunPower X-Series panel. This solar panel has the following specs that make it a leader in hot climates: An industry-leading efficiency of 22.7%; An annual efficiency loss of 0.25%; A temperature coefficient of just -0.29%/degree C, which is well below average;
It is well accepted by the main test laboratories that the current version of the hot-spot method does not represent, nor is it able to represent a real hot-spot situation. An improved hot-spot method has been drafted within TC82 of the IEC and is expected to become normative with the 3 rd edition of IEC 61215 in 2010.
Micro-cracks represent a form of solar cell degradation and can affect both energy out and the system lifetime of a solar PV system. The silicon used in solar PV cells is very thin (in the range of 180 +/- 20 microns) and hence is susceptible to damage easily if the PV module''s production and handling are not up to the required standards.
