Choosing A Solar Inverter Type
You will also want think carefully about which kind of solar inverter works best with your solar energy system and roof. Solar inverters convert the DC electricity that comes from the solar panels into AC electricity that is usable in your house. Choosing a solar inverter can get a little confusing, so it may be best to simply talk to local solar installation contractors about your specific needs.
There are three basic kinds of solar inverters:
- Central or String
- Power optimizers
Can Solar Panels Withstand Strong Winds
Modern solar panels are designed, engineered, manufactured, and tested to withstand a wide range of weather conditions. This includes high winds. In general, solar panels hold up well in windy conditions, being highly resistant to damage. The only limiting factor can be the quality of your roof or the racking system. Because of this, it is essential that you hire experienced and trustworthy solar installers who can ensure the highest wind resistance possible.
Different Types Of Solar Panels
There are three types of solar panels- Tier One, Tier Two, and Tier Three divided based on the quality of raw materials used. Its also based on the amount of time, research, and development invested in its manufacture.
Companies producing Tier One solar panels have invested substantial time and money into research and development. Consequently, their solar panels are the most durable and efficient in construction.
Other factors affecting solar panel durability
Its not just the construction that matters. There are a few other factors that determine how durable and long your solar panels last.

How 3000 Solar Panels Measured Up Against A Massive Hail Storm
The National Renewable Energy Lab in Golden, Colorado, can attest to the resilience of solar panels against extreme weather. The NREL is home to an enormous solar energy system consisting of 3,168 rooftop- and ground-mounted solar panels. In 2017, a severe hail storm hit the greater Denver area and the NREL campus.
Despite hailstones up to 2.75 inches in diameter being reported in the area and the countless cars and windows that were damaged only one of the facilitys 3,168 solar panels sustained damage. Thats a major testament to the resilience of solar panel systems.
For Warm & Dry Climates
Living in the Sun Belt or in another hot and sunny region? Youre in a prime spot for premium solar panel efficiency. In this case, you may also consider temperature coefficient as a leading factor in your decision makingfor example, Panasonic and REC both boast an impressive -0.26 temperature coefficient and a 25-year warranty which is great considering solar panels are a long-term investment.
On a final note related to region and climate, it can sometimes be useful to consider solar panel maintenance and cleaning as part of your yearly routine. Solar panels in areas that suffer from severe storms, wind, or even pollen buildup in the spring, can quickly accumulate dust and debris which reduces efficiency. A quick washing or professional soft washing should do the trick .

Tier 1 Chinese Solar Panels Now Offer High Efficiency At A Lower Cost
Premium efficiency solar panels like SunPower, LG, and Panasonic have always come at a higher price than standard efficiency panels. But, thats all starting to change, as there are now several new Tier 1 Chinese solar companies that offer high-efficiency solar panels at a very low cost.
To give you an idea, at the wholesale level before installation, SunPower, LG, and Panasonic panels cost around $0.80 per watt. Some of their most efficient models are sold for as high as $1.00 per watt. Chinese solar manufacturing giants like Canadian Solar, Trina Solar, and LONGi, on the other hand, are now offering panels with efficiency ratings over 20% for about $0.40 per watt.
And these Chinese-owned companies are by no means back-alley manufacturers – they have some of the largest, most technologically advanced solar panel production facilities in the world. Canadian Solar, Trina Solar, and LONGi each manufacture more than 12 gigawatts of solar panels per year, while SunPower produces just 2.5 GW.
This means that solar is not only cheaper than ever, its also more efficient than ever. The cheaper Chinese panels also begs the question: will the big three premium manufacturers be able to hold onto their price premium? This could particularly be an issue for SunPower, as their IBC cells are said to be more expensive to manufacture which could be a reason why SunPower chose to spin-off its manufacturing business, Maxeon Technologies, in 2020.
Durability / Longevity / Warranty
The durability or longevity of a solar panel warranty is important for a number of reasons it can be an indicator of the manufacturers confidence in its products. Reputable solar panels will have a performance warranty a period of 25 years. All of our key modules including REC Solar, feature this 25 year warranty period.
However, an important point to remember about warranty is that it will only be honoured for as long as the company operates. Its another reason to select a well known brand of module rather than purchase an obscure low-cost brand that may disappear overnight.
As you most likely wont buy solar panels directly from the manufacturer, selection of installer and retailer is also important. Its best to choose an installation company that is a service agent for solar panel warranty work for the manufacturer you select. This is because if you do strike a problem, the turnaround time to a resolution will be far faster.

Install Solar Panel Protective Covers
If you are in a hail storm-prone area, installing solar panel protective covers is a sagacious move. The covers are made from Sunbrella marine fabrics, which protect solar panels from adverse weather conditions such as snow, hail, sleet, and heavy debris carried by strong winds.
The covers are also essential during strong sunshine that can cause overheating. The material used in manufacturing solar protective cover is strong and can absorb any shock. It can withstand hailstorms blowing at 50 miles per hour. Hailstorms blowing at such speeds are very strong.
If you do not install the protective cover, the hail can cause irreversible damage. Installation of a solar protective cover is a long term investment because the material can last for more than ten years.
What Wind Speed Can Solar Panels Withstand
Modern solar panel systems can withstand winds of at least 140 miles per hour . Such winds are much worse than what most people encounter. With this in mind, you wont experience any significant issues with your solar panels unless you live in an area known for severe hurricanes.
That being said, you wont be able to rely on your solar panels for electricity during extreme storms if your system is tied to the grid. Still, this is just a temporary issue, as youd be able to use your solar system as soon as the grid is back up.
In rare cases, wind may throw heavy objects into solar panels, causing localized physical damage. Keep in mind that an extreme hurricane is needed for this to happen.

Solar Panels In High Winds And Tornadoes
Solar panels resistance to wind is dependent on a variety of factors relating to how and where theyre installed. Wind travels between the bottom of solar panels and the roof or between the panels and the ground . This creates an uplifting force, and if not installed properly, your panels could blow off their racking.
But how likely is this, even in extreme winds? As it turns out, not very. If this does happen, its most often because of a failure in the systems racking or the roof that the system is attached to, not the panels themselves.
76% of tornados have wind speeds ranging between 40-112 mph, and most solar panels are certified to withstand winds of about 140 mph.
But this varies based on your location. Local building codes, which are based on the areas weather, dictate the wind speeds that solar systems need to withstand. For example, in Florida, where strong, hurricane-force winds are common, solar panels must be installed to withstand winds of up to 185 mph.
What Is Solar Panel Efficiency
Solar panel efficiency measures how much of the sunlight that hits the surface area of a solar panel is converted into usable electricity.
The higher the efficiency rating, the more electricity the solar panel is able to produce from the amount of sunlight that shines on your roof. So, if a solar panel has a 15% efficiency rating , that means 15% of the solar energy within the sunlight that hits the solar panel will be converted into electricity.

Can Hail Damage Solar Panels
Have you ever left your car out in a hailstorm only to find it had more dimples than a golf ball afterward?
Then, you know firsthand the damage these little pieces of ice falling from the sky can cause. But, fortunately, when it comes to hail, most solar panels are certified to stand up against one-inch hail falling at approximately 50 miles per hour.
When damage from hail does occur, its usually caused by concentrated impact in small areas. And its rare, a point well illustrated by recent severe weather in Denver.
In May of 2017, the Mile-High City was pelted with baseball-sized hail that injured many. The hailstorm provided the National Renewable Energy Laboratory located in the city with the perfect opportunity to test the durability of the more than 3,000 solar panels on its rooftops.
Despite the size and force of the hail that hammered down on the lab, only one solar panel was damaged, a true testament to the fact that todays panels are built to last.

Vermont Projects Without Approval
In June 2017 the Vermont Public Service Board found that SolarCity was implementing solar projects in Vermont without approval required by law. According to Vermont Public Radio, Public Service Board Chair Anthony Roisman sent a letter to SolarCity warning the company that it needed to get regulatory approval before installing solar generation equipment and attaching it to the state’s electrical grid. Roisman wrote, “Over the past few months, my office has observed a pattern of procedural issues with net-metering applications being pursued by your company.” Officials at the company worked quickly to respond to the issue.
Direction Roofs Suitability And Angling:
Your roofs angle has a huge role to play how much daylight exposure your solar panels can get. Anyway, to get the best results, domestic panels must face south. In that way, solar panels are exposed to sun sunshine as prolonged as possible. In research, it found that a 34-degree roof tilt angle is the fittest one.

Solar Panel Testing And Certification
Testing and certifications by the solar industry have helped to develop standards for assessing solar energy system quality and durability this includes their ability to undergo severe weather conditions in multiple climates.
At the helm of this testing is the International Photovoltaic Quality Assurance Task Force , which is funded by the SunShot Initiative. The SunShot Initiatives mission is to make solar more accessible and cost-effective for all Americans. By funding NREL scientists to work with the PVQAT, Americans can also be confident in their solar systems performance and durability.
The PVQAT develops standardized quality tests to make sure solar modules can survive various climate conditions, monitors quality management of the manufacturing process, and establishes guidelines for system quality inspections to ensure your solar installation has been designed and installed properly.8
Thanks to the work of the PVQAT, we can have even more confidence in solar energy systems. Their work is especially important as the demand for clean, solar energy grows in the face of increasingly severe weather due to rising global temperatures.9
Best Solar Panels Based On Your Region And Climate
After youve considered the efficiency, temperature coefficient, and warranty on any particular solar panel, its important to take the next step and think about your homes individual circumstance. Its no secret that solar panels are more often found in the Sun Belt compared to other parts of the country, but thats not to say that homeowners in the Northeast or Midwest should totally rule them out.
First, there are several factors that affect solar panel efficiencyfactors that can be impacted by your region and climate. These include irradiance, shading, panel orientation, temperature, location and latitude, time of year, and dust and dirt. For example, if you live in an area that doesnt get a lot of sunlight and your home is prone to shade and overcast clouds, youre not going to be able to produce as much clean energy for your home. When a panel is covered by shade, the power output is very loweven light shading can have a negative impact. In fact, subtle shading that covers a few cells or a single panel can reduce power output by 50% or more. This is why the orientation of your home in relation to the shade and wet weather patterns is so important.
