In an article published at HubPages, I reviewed questions and answers that many people have about solar power generally, and solar panels in particular.
Q: Is it expensive to install solar panels?
A: Not necessarily! Depending on where you live and your energy needs, you could install a home-based solar panel system for as little as $7,500. Many states offer incentives to off-set the cost of solar panels, as well. Don’t forget energy tax credits!
Q: How long will it take to recoup my investment in solar panels?
A: The answer to that question depends on a number of factors, including the size of the solar panel system (number of panels), your overall energy use, tax rebates and other incentives. Estimates range between 10-15 years. As solar technology leads to more efficient solar cells, and grid-payback systems are implemented by energy companies, expect the ROI to drop to 5-10 years. Thinking beyond just monetary investment, your contribution to help slow global warming and reduce your carbon footprint will lead to an immediate payback.
Q: Does the process of manufacturing solar panels result in pollution?
A: Yes, there is some environmental impact from producing solar panels, as there is with any other manufactured good. But, the environmental costs of manufacturing are outweighed by the environmental benefits of reduced fossil fuel consumption. Even the smallest solar panel system can cut household greenhouse gas emissions by as much as 50 trees! And remember that 100% of the electricity produced by solar panels is emissions-free!
Q: Solar power has always been a clean renewable resource – why has it taken so long for people to get interested in solar panels?
A: Since the earliest civilizations, people have been using solar power to warm their shelters and cook their food. But modern solar panels have only been around for about 50 years. Solar research and development is leading to more and more efficient solar cells, with higher conversion rates. Prices are dropping, as well, as materials become more abundant and processes more streamlined. Still, less than 3% of our nation’s electricity is generated by solar power. Experts expect that to change over time, with solar energy generation growing at a rate of 20-30% annually. With added tax incentives, concerns about global warming and a strong desire to become energy independent, more and more people are willing to invest in solar panels.
Q: What about excess energy generated by solar panels?
A: If your solar panels create more power than you can use immediately, excess energy can be used to charge batteries on which you can draw later (if you are “off-grid”). With grid-tied systems, the extra power is fed into the grid. Some utilities credit customers based on the amount of energy put into the grid. This helps defray costs of power drawn on overnight or during less efficient solar energy periods.
