Поликристалл против монокристалл. Тест в хорошую погоду

Comparing the cool temperature performance of monocrystalline vs. polycrystalline PV solar panels. I ordered 3 of these 135w panels and one came as a polycrystalling which was interesting. They have identical specifications for Standard Test Conditions (STC). Generally speaking monorystalline performs better than polyrystalline when it’s cool but polyrystalline does better in hot temperatures. I will repeat this test when summer comes.
