The cost of completely converting a home so that everything is electrically powered by solar energy is estimated at $50,000. This includes replacing batteries every five years. While $50,000 is an unreasonable amount for most families to pay, the long-term benefit of having no power bill will eventually make up for the money spent. Additionally, payment plans and incentive programs make solar energy more affordable for some. Teach kids that solar companies must find a way to make their services affordable in the future and have older children begin innovating potential ways to structure the business of solar energy. Additionally, explain that households using less energy can function with fewer solar panels and thus save money. Kids should know that energy-saving strategies will still be important to incorporate with, rather than replace, solar energy. Likewise, kids should be able to identify energy saving skills.
As of 2011, solar panels must be placed somewhere that is large, unobstructed and relatively flat. The area must receive sunlight at least five hours a day. Frequently overcast weather and large trees can prevent solar panels from working properly or mean that families need to invest in additional panels, which is usually not a financially feasible option. Solar panels may be placed on a roof top. However, working with a solar system makes roof repair tremendously expensive because all panels must be removed and then reinstalled. Some people also report that the appearance of solar panels is unattractive and will ruin the look of carefully shingled roofs and manicured yards. Kids can learn about these drawbacks and brainstorm potential constructions that would look more appealing and serve an additional structural function.
Solar panels are connected to batteries which are typically buried in the ground. The batteries must be replaced about every five years for efficiency and must be subjected to strict maintenance. The batteries contain lead, sulfuric acid and cadmium, each of which has been proven toxic to humans and the environment. When teaching children about the disadvantages of materials used in solar system batteries, have them brainstorm ways to make battery maintenance and recycling uniform for all members of a solar-powered community.
Although there are some significant disadvantages to using solar energy, these can be addressed through continuous research and innovative planning. The advantages of solar still outweigh the drawbacks and children taught from an early age to consider the issues preventing full-scale solar implementation will be poised to develop potential solutions.
