Disadvantages of solar panels are; capital cost, manufacturing-related pollution, weather dependence, efficiency challenges, storage limitations, space constraint and scarcity of raw materials.
Passive solar heating examples are; sunroom space heating, passive water-reservoir heating, solar greenhouse warming, thermal-absorption using Trombe wall, and indirect gain in solarium.
Passive solar heating is the concept and practice of capturing, storing and consuming heat from the sun using non-mechanical systems. Passive solar heating definition
Pond vs lake comparison can be made using areal coverage, vertical extent, biological productivity, zonation, and water composition, to identify similarities/differences.
Advantages of active solar energy are; role in energy transition, ecosystem compatibility, low overall cost, multiple uses, and increase in property value.
Examples of active solar energy systems are; pumped-solar air heating system, concentrated solar plant, solar water heater, fluid-based radiator, hybrid solar cogeneration system.
Active solar energy is solar energy that is collected and transferred to a working fluid, which conveys and converts it for use. Active solar energy definition
Disadvantages of passive solar energy are; potential insufficiency, non-renewable energy combination, geography-dependence, design problems, storage limitations.
Advantages of passive solar energy are; relatively-low cost, minimal environmental impact, simplicity of use, non-alteration of building, and role in energy transition.
