Debunking Misconceptions About Solar Energy

July 11, 2022


Solar energy, despite being an invention that originated in the 1880s, is a rather new concept to us today. As it is the only renewable energy source in Singapore with the highest deployment potential, our government is stepping up efforts to deploy solar energy across the country. However, many Singaporeans may be hesitant to adopt solar power due to certain misconceptions they have about it. In today’s article, we’ll debunk some of these myths and clear up any misconceptions you may have about solar energy.


#1 Solar Panel Installation will Damage My Roof


Solar panel installations are only conducted by professional engineers and workers who have been trained to handle such projects; they have the necessary equipment and expertise to safely install solar panels on your roof without causing damage. 


Furthermore, solar panels act as a layer of protection for your roof, shielding it from the elements and providing multiple other benefits such as reducing the amount of heat entering your home through your roof. 


#2 Solar Cells Only Work on Sunny Days

Modern solar panels work reasonably well even on cloudy days. Although not as effective as they would on a sunny day, solar cells can still convert sunlight into a significant amount of electricity. Fun fact, solar panels can easily capture different parts of the sun’s light spectrum and use the sun’s rays to generate energy even when sunlight isn’t beaming directly onto the panels. 


#3 Solar Energy is too Expensive


Although the cost of installing solar PV systems was extremely high in the past, it has now reached grid parity, with prices dropping by more than 70% since 2009. Solar panels for homes are becoming more affordable, and switching to solar energy can help homeowners save even more money in the long run. However, for the time being, solar panel installation can only be done for landed properties.


Commercial building owners have several solar energy financing options to choose from if they wish to adopt solar.


  • Power Purchase Agreement – This enables commercial building owners to adopt solar energy without having to fork out any upfront investment costs. The solar company will fully finance the installation and maintenance of your solar PV systems, and building owners will only be charged for the amount of energy used. 


  • Solar Roof Rental Scheme – This scheme allows businesses to rent out unused roof space to a solar company in order to facilitate large-scale renewable energy generation. Building owners will be able to purchase the solar energy generated for their own use. 


#4 Solar Panels Have Short Lifespan


Solar panels today are constructed of sturdy materials that are extremely tough and durable. They can typically last beyond 20 years with regular maintenance


#5 Solar Panels Decrease the Resale Value of My Home


As a clean energy option, solar power reduces one’s carbon footprint and even lowers and controls energy costs while providing money-saving rebates to the homeowner or building owner. Due to the numerous benefits they provide, they actually contribute to an increase in the resale value of your home. 


#6 Solar PV Systems Require Lots of Maintenance

Solar PV systems are made up of long-lasting components that don’t require much maintenance. Simply cleaning away dirt, debris, and any foreign objects stuck on top of the panels is enough to keep your solar panels in good shape. However, it is recommended that regular maintenance be performed by a professional at least once a year, so that potential issues can be identified and resolved before they become a major concern.


Switching to solar energy is an excellent move if you have the means to do so, not only are they good for our environment, but they are also cost-saving in the long run. Now that you have a better understanding of solar energy and solar panel installations, are you more likely to use solar as your primary source of energy?
