Solar energy has established itself as one of the best sources of renewable energy. Over the past five-ten years, solar has proved to become a leader in that sector. While many of the discussions of solar energy have been about its benefits, there are still several common negative myths of solar energy circulating. We want to take this opportunity to go over some of those myths of solar energy and installing solar panels and to debunk them.

Myth 1: Solar Panels Will Not Pay for Themselves

The return on your solar panel investment has been a question that has been asked by many. Solar energy from the first month can create massive cuts in your electric bill, and the return on the investment starts as soon as the solar energy system is activated. Also, there are both state and federal tax credits that help home and business owners offset more than 50% of the system (as of 2020). To read more about the ROI of a solar energy system, look at our blog pertaining to the ROI for a Long Island homeowner here.

Myth 2: Solar Panels Don’t Work As Efficiently When It’s Cloudy or Raining

Solar panels or Photovoltaic panels either can use direct or indirect sunlight to generate power; though they are more effective in direct sunlight, this does not mean they will not work while it is cloudy. Solar panels will still work and produce energy even when the light from the sun is either reflected or partially blocked by clouds. Also, the rain helps the panels operate efficiently by washing away any excess dust or dirt.

Myth 3: Solar Panels Will Damage Your Roof

This myth is a common question asked by Long Island homeowners going solar. They are concerned with either the installation or weight of panels being on their roof if it will provide damage in the future. Professional installers are trained to inspect the roof before installation to ensure the structure is strong and sturdy enough to hold the solar panels. As for penetrations and concerns for leaks, these installers are trained to work with almost any roof type using special tools and well-tested techniques.

Myth 4: Installing Solar Panels on My House Will Decrease its Value

If you think installing solar panels on your home will decrease its value in any way, think again. A recent study held by Zillow analyzed home sales throughout the country that had solar panels installed on their home. According to the Zillow study in the year of 2018, homes with solar panels installed sold for 4.1% more for the median-valued home an additional $9,926. In New York, the percentage is slightly higher at 5.4% more for solar panels installed.

Myth 5: Solar Panels Require a lot of Maintenance

In a solar electric system, there are no moving parts, so very minimal to no maintenance is required. Depending on the location of the solar panels, the cleaning of the panels is very rarely needed. Like here on Long Island, we have a general rainy climate, which is enough to keep the panels free of dust. However, if you live west in states like Arizona, cleaning solar panels a few times a year is typical.
