Despite the overwhelming growth of residential solar installations, many myths remain about solar power. Here are the top 10 solar power myths — and the facts that refute these myths.
Myth: Solar panels do not work well in cold climates.
Fact: Most solar panels actually work best in cold, sunny conditions. Conductivity increases in cold temperatures, making electricity flow more efficiently, while higher temperatures can reduce the panels’ efficiency. As solar panels get hotter, they produce less power from the same amount of light.
Myth: Solar power will get more efficient, so I should wait to buy or install.
Fact: While many companies are working to improve the efficiency of solar panels, the current technology for solar panels is well established — in fact, we’ve been using the same solar technology, more or less, since the 1960s. The potential efficiency gains of future panels are small compared to the panels ready for installation today, and the efficiency gains when measured in total dollars saved on your energy bills is miniscule.
Myth: I won’t live in my home long enough to make my investment in solar back.
Fact: Depending on your system and location, solar panel arrays can pay for themselves within 6 to 15 years. Combined with the best state and federal tax credits and incentives, you could start seeing a return on your investment within 2 to 4 years. Solar panels also increase the resale value of a home by about $15,000, so even if you won’t be in your home for the next 15 years, you can still see a significant return on investment when you sell. continued…
