Solar power is great overall, but some disadvantages are that solar panels, installation, and repairs are VERY expensive. Also, the weather can effect the efficiency of the solar panels. Solar panels can only process energy throughout the day, even though it usually has enough power saved up to run everything all through the night, which is another disadvantage. And pollution levels can also effect the solar panels efficiency.
The main disadvantage of solar cooker is that, it is less usable during cloudy and rainy days. Also, it takes longer time to cook the food compared to an oven.

A solar cooker and a pressure cooker are two completely different ways of cooking. A pressure cooker can still use a heat source like a gas or electric cook top. A solar cooker is as the mercy of the heat of the sun and the contents will only cook as well as the amount of heat it obtains.
A panel cooker is a way of using solar power to cook an item. The advantage of using a panel cooker is that it is using solar energy and not electricity.
