Should you’ve ever talked to a gaggle of individuals about photo voltaic panels, you’ve got most likely heard a number of sturdy opinions. But it surely appears a number of what individuals i believe they know it isn’t true for photo voltaic panels.
Photo voltaic panel expertise first materialized within the Nineteen Fifties and has superior considerably since then. Whereas expertise continues to enhance, a lot of the stigma surrounding it’s a factor of the previous.
So, let’s debunk the commonest myths about photo voltaic panels.
Direct to: Photo voltaic panels are too costly | Photo voltaic panels solely work when the solar is shining | Photo voltaic panels cut back house worth | Photo voltaic panels usually are not environment friendly sufficient | Solely owners can use photo voltaic | Photo voltaic panels will injury a roof | Photo voltaic panels hurt the atmosphere greater than they assist it Photo voltaic panels are ugly
1. Photo voltaic panels are too costly
A 2022 EcoWatch survey discovered that 60% of house owners agree that photo voltaic panels are too costly. Value was additionally the primary purpose owners mentioned they would not contemplate putting in them.
We’ll begin by saying that photo voltaic panels for properties usually are not low-cost. However the worth has dropped by about $20,000 up to now decade. Based on the Photo voltaic Power Industries Affiliation (SEIA), the typical residential photo voltaic panel system has dropped from $40,000 in 2010 to roughly $20,000 in 2021.1
These are additionally the figures earlier than incentives. Taking the federal tax credit score into consideration, a $20,000 system would drop to $14,000. Some states additionally provide extra photo voltaic incentives that may decrease photo voltaic prices even additional.
In the meantime, the value of retail electrical energy is rising, with the typical electrical invoice rising from roughly $110 in 2010 to $122 in 2021.2
You need to consider photo voltaic power as an funding that may repay over time. Between the power financial savings, tax credit, rebates and photo voltaic financing choices, many householders are discovering that solar energy is way more reasonably priced than beforehand thought.
2. Photo voltaic panels solely work when the solar is shining
Our EcoWatch survey additionally revealed that 40% of house owners imagine that solar energy solely works when the solar is shining.
To search out out if that is true, we requested Dr. Greg Poelzer—a professor within the College of Surroundings and Sustainability (SENS) on the College of Saskatchewan—if photo voltaic panels nonetheless work on cloudy days.
“As a result of the clouds usually are not utterly opaque, daylight nonetheless passes by them and reaches the photo voltaic panels,” Dr Polzer mentioned.
“The electrical energy produced could also be decrease than on cloud-free days, however there’s a vital distinction between daylight that spreads by cloud cowl versus daylight that’s blocked by stable objects corresponding to tall buildings.”
Analysis exhibits that photo voltaic panels usually generate 10 to 25% of their normal energy output on non-sunny days.
3. Photo voltaic panels can cut back house worth
Some individuals attempt to argue that photo voltaic panels will cut back the worth of the house. However in keeping with our survey, 70% of house owners imagine photo voltaic panels enhance a house’s resale worth, and 63% of house owners say they’d pay extra for a house with photo voltaic panels than one with out.
However once more, you do not have to only take our phrase for it.
A Zillow examine discovered that properties with photo voltaic installations usually promote for about 4.1% greater than properties with out.3An older examine from Lawrence Berkeley Nationwide Laboratory discovered a rise in resale worth of roughly $5,911 for each kilowatt of photo voltaic put in.4
There you will have it – photo voltaic panels actually do enhance the worth of a house.
4. Photo voltaic panels usually are not environment friendly sufficient

Truthfully, it is as a result of it does not should be. Photo voltaic power is way more highly effective than normal electrical energy.
Based on the Division of Power, simply an hour and a half of sunshine can energy the world for a whole yr.5 Which means photo voltaic power is greater than able to powering your private home.
Based mostly on inner calculations, the typical US house owner can offset all of their family power wants with a 9 kilowatt (kW) photo voltaic panel system. But it surely additionally relies on what sort of photo voltaic panel they select and whether or not the house has an power storage system.
Caltech professor Nathan S. Lewis mentioned that if a home-owner installs a monocrystalline photo voltaic panel like SunPower’s, it is going to be very environment friendly for family wants, particularly for owners who do not have a number of area.
“[Sunpower Panels] are of nice worth for restricted areas as a result of the upper effectivity signifies that one [panel] can produce extra electrical energy from a small roof than could be produced from decrease effectivity panels to assist meet the total electrical energy wants of a family,” Dr Lewis informed EcoWatch.

5. Solely owners can go photo voltaic
There are lots of methods to make use of photo voltaic panels as a tenant or enterprise proprietor, corresponding to getting mini photo voltaic panel techniques or photo voltaic powered home equipment. However the easiest way is to affix a group photo voltaic program.
Neighborhood photo voltaic permits individuals who don’t personal their properties or stay in an residence constructing to learn from photo voltaic power by a shared photo voltaic array. These arrays are often put in off-site and you should purchase a share or pay a month-to-month subscription to entry the photo voltaic power that the photo voltaic system produces.
Though you will not be capable of make the most of photo voltaic incentives, becoming a member of a group photo voltaic undertaking remains to be a good way to decrease your electrical invoice and your carbon footprint.
6. Photo voltaic panels will injury a roof

Photo voltaic panel manufacturing at the moment relies on fossil fuels and valuable steel mining, which contributes to greenhouse gases and air pollution. There may be additionally the issue of recycling photo voltaic panels, which has not but been absolutely resolved.
Nevertheless, even with their drawbacks, photo voltaic panels are way more environmentally pleasant than the choice. Burning coal generates a footprint 18 instances bigger than photo voltaic, whereas pure fuel creates an emissions footprint 13 instances bigger.6
Photo voltaic power additionally produces zero emissions after manufacturing, making it a key resolution to slowing local weather change. And as expertise advances, we count on the method of making photo voltaic panels to grow to be much more environmentally pleasant.7
8. Photo voltaic panels are ugly
Okay, it is onerous to name this a fantasy. However that is an argument some owners make for not wanting to put in photo voltaic panels. The EcoWatch survey revealed that 31% of house owners assume photo voltaic panels are ugly.
Disliking the look of photo voltaic panels was additionally the second hottest purpose for owners to say they would not set up photo voltaic panels, simply behind them being too costly.

Many have praised thin-film photo voltaic panels for his or her glossy design, however as a result of they aren’t as environment friendly, they aren’t the best selection for powering a whole family. However in keeping with Dr. Poelzer, that might change quickly.
“Technological advances in thin-film photovoltaic analysis are additionally quickly necessitating this lighter, extra versatile and fewer temperature-sensitive choice to realize effectivity ranges that rival mono- and polycrystalline techniques,” mentioned Dr- r Poeltzer.
Moreover, corporations like Tesla are growing applied sciences like photo voltaic tiles to make high-efficiency photo voltaic modules extra aesthetically pleasing.
Because it stands now, photo voltaic roof tiles usually are not as extensively obtainable and are way more costly than normal photo voltaic roof panels. However because the expertise turns into extra common and cheaper to fabricate, photo voltaic roofs will grow to be extra reasonably priced for owners.
