A lot of fake news and misinformation about the home solar power system has been doing the rounds like Mike Tyson in his prime. We have gathered up a few of the fake news or myths surrounding residential solar systems, we will be debunking 9 of the most popular myths in this article.
This video below demonstrates how a grid-tied home solar power system works. It shows the exact process from the moment sunlight hit the solar panels, the actual power conversion and how the DC(direct current) electricity from the panels converted to AC(alternating current) for home use, as AC is the compatible form of energy for most home appliances.
9 Myths About Home Solar Power System
Myth #1: Home Solar Power System Will Be More Efficient, Should You Wait?
Fact: These days the media loves to hype emerging technologies, but the truth is we're still using the same solar technology we were back in the 1960s. Since then, solar has become only moderately more efficient (unlike computers or cellphones which experience dramatic improvements in short periods of time).
Myth #2: Solar Power Does Not Work In Cloudy, Foggy and Cool Places
Fact: Solar panels work just fine in ambient light and will produce significant energy in the fog or on overcast days. In fact, solar panels are actually more efficient at cooler temperatures than hot ones
Myth #3: Home Solar Power Energy Is Stored In A Battery Bank
Fact: Nearly all modern solar panel systems are grid-tied which means they're connected to the conventional electricity grid. Your system generates power during the day and excess is fed back into the grid through a system called net metering. When this happens, your meter spins backward and your utility company credits you for that power. Note: This only happens in certain areas around South Africa. See https://sola.africa/faq/

Myth #4: Solar Panels For Home Needs Constant Maintenance
Fact: Solar panels have no moving parts and do not require regular maintenance. Typically the recommendation is to hose off the panels once a year or so, but many panel owners actually never clean the panels and instead rely on the rain to do the job for them. Typically this will cause only a very slight loss in efficiency (about 5%) over the lifetime of the panels.
Myth #5: Home Solar Power Panels Caused Roofs To Leak, Deteriorate or Even Collapse
Fact: Solar panels actually protect and preserve the portion of the roof they cover, but don't take our word for it. Check out this picture of solar panels that have been through a hurricane. If there's ever a problem with the roof that needs to be repaired, panels can easily be removed.
Myth #6: Home Solar Power System Is Very Expensive and Will Never Pay For Itself
Fact: Perhaps one of the most unfortunate solar myths is that it's only for rich people or environmentalists when in reality many homeowners choose to go solar simply because it eliminates their big monthly electricity bill. In fact, solar is a very wise choice for people who could actually use the extra couple hundred bucks a month that they're currently paying in power bills.

Myth #7: When Grid Power Is Out, The Home Will Not Have Power Using Solar Energy
Fact 1: When the power goes out, grid-tied systems go out too. That's because it's not safe to be pushing electricity back out onto the wires while workers may be trying to fix the problem, so your inverter (the big box near your meter that turns DC electricity created by the panels into usable AC current) recognizes that the grid is out and shuts your system off. BUT, With an Offgrid or Hybrid Solar System, you can still have power even if the grid is off. For more info about the difference between Grid-Tie vs Off-Grid vs Hybrid Solar System click here.
Myth #8: Home Solar Panels Will Make The Roof Appear Ugly
Fact: In the last ten years there's been a growing awareness of how smart renewable energy is from both environmental and economic perspective, so solar panels are finally coming into their own and being regarded as an enhancement instead of an eyesore. It's about time! Homeowners' associations that used to be steadfastly against solar have changed their policies and are now going solar in groups.

Myth #9: Home Solar Panels Require a Tracking System To Follow The Sun's Angle
Fact: Though tracking mechanisms can provide efficiency gains for your solar panel system, they typically do not increase efficiency enough to justify the additional expense and maintenance of moving parts in residential situations. More importantly, most homeowners don't have the additional space required for these systems.
