I just answered this question from a different person but I like helping with science. This is from the water's breeze or air currents. This makes the climate mild while the inland is more extreme because it does not have the breeze. Hopefully this helps :D
Solar cells usually convert solar energy into electricity which could later be reserved. The efficiency of solar cells is still low, compared to other sources, with a conversion rate of 15% - 22%. This reduces the attractiveness of solar cells as a competitive source of energy. This also makes this form of energy expensive due to its inefficiency.
