- The solar panels are environmentally friendly and do not contribute to climate change as in the case of the use of fossil fuels because the solar panels do not emit harmful greenhouse gases such as carbon dioxide.
- Solar panels harness the sun and solar energy is the most abundant form of energy available on our planet.
- The solar panels are easy to install and has a very low maintenance costs because there are no moving parts.
- Solar panels do not contribute to noise pollution and working with very silent.
- Many countries around the world offer incentives for homeowners who use solar panels.
- Solar panel prices continue to fall even though they still have to compete with fossil fuels.
- Not required to purchase all the necessary solar panels in the same time, but can be purchased gradually, which means you do not have to make big investments in an instant.
- Solar panels do not lose a lot of efficiency in the life of those who achieve 20+ years.
- Long battery life time, mecapai 25-30 years, guarantee users will save on energy costs in the long run anyway.
Weaknesses Solar Panels:
- The solar panels are still relatively expensive, even though after much decreased price. House panel prices are currently around $ 12,000 to 18,000.
- Solar panels still need to improve efficiency significantly as much sunlight wasted and turned into heat. The average solar panels currently account for less than 20% efficiency.
- If not installed properly can occur over-heating solar panels.
- The solar panels are made of several materials that are not environmentally friendly.
- Recycling unused solar panels again can cause environmental damage if not done carefully because silicon, selenium, cadmium, and sulfur hexafluoride (a greenhouse gas), all of which can be found in solar panels and could be a source of contamination during the process of recycling
