Solution:
Advantages of solar appliances:
- Renewable Energy Source
- The ecological footprint is much smaller since greenhouse gases are not generated, since coal burning is not used.
- Reduces Electricity Bills
- Diverse Applications: solar energy can be used to produce electricity in areas without access to the power grid, distill water in regions with limited clean water supplies, and power satellites in space.
- Low Maintenance Costs: Most solar panel manufacturers offer a 20-25 years warranty. Solar power systems only need to be relatively clean.
There are no moving parts, there is no wear. The inverter is usually the only part that needs to be changed after 5-10 years. It works continuously to convert solar energy into electricity and heat (solar PV vs. solar thermal).
Disadvantages of solar appliances:
- The initial cost of purchasing a solar system is fairly high.
- Weather-Dependent: Solar panels are dependent on sunlight to effectively gather solar energy. Therefore, a few cloudy, rainy days can have a noticeable effect on the energy system.
- Solar Energy Storage Is Expensive: the batteries, used in off-the-grid solar systems, can be charged during the day so that the energy is used at night. This is batteries are expensive.
