Which Solar Panels Are The Best

Best Solar Panels For Wind Prone Areas

Nobody wants to invest a cool $20k on solar panels only to have them wrenched from the roof or mangled beyond recognition in a wind-storm. So, if you live in a particularly wind-prone area and are considering a solar array, look for panels with extremely strong framing and a reputation for standing up to a good whipping wind.

Some good options include Winaico and Q.Peak DUO panels from QCELLS. Winaicos panels have an impressive reputation for durability and the company has led the way for years on durability and innovation to make panels more resistant to wind, hail, and other weather extremes.

Install The Solar Panels

Once the frame has been attached, the installation of the solar panels can begin. The panels are clamped to the aluminium frame but not too tightly at first, in order to have some space to adjust them slightly later. Once all panels are set up in their position, they are firmly secured to the frame.

Panel Size Vs Efficiency

Panel efficiency is calculated by the power rating divided by the total panel area, so just having a larger size panel does not always equate to higher efficiency. However, larger panels using larger size cells increases the cell surface area which does boost overall efficiency.

Most common residential panels still use the standard 6 square 60-cell panels while commercial systems use the larger format 72 cell panels. However, as explained below, a new industry trend emerged in 2020 towards much larger panel sizes built around new larger size cells which increased panel efficiency and boosted power output up to an impressive 600W.

Can You Diy A Solar Panel Installation

Its tempting to save money and install solar panels yourself, especially if you have numerous successful DIY projects under your belt. But installing solar panels is a project that is best left to the pros. Depending on the type of panel you choose, installation might require complex configurations that are otherwise difficult to install correctly without the training experience.

Additionally, professional installation might be required to uphold the warranty. As with many projects, getting a professional to install a solar energy system means that it will be done right the first time so that you can begin reaping the benefits of it immediately.

Best Solar Panels Made Or Designed In America

For some homeowners, finding American made solar panels is a priority. While there are several fantastic solar makers headquartered in the US, finding panels that are truly made in America can be tricky.

Thats because there are American companies that manufacture overseas, and overseas companies that manufacture in America. And then there are companies that manufacture some panels in the US and others abroad.

Best solar panels manufactured in the US

Whether your heart is set on supporting American manufacturing, American-based companies, or both, there are options when it comes to solar panels.

How Much Do Solar Panels Cost

The total price of a solar panel system will vary based on the size of your roof, your location, the number of panels you need to meet your energy needs, and many other factors. Is your roof south-facing? Is your house multi-level or partially covered by shade? There are many variables that can make your system straightforward to assemble, or very complex.

Other external factors like supply chains, local availability, government incentives and local electricity rates will also affect the cost of solar panels. How much you get back from your system also depends on these factors, plus whether you finance your solar system or pay cash. By paying cash, you are spending less per watt of energy generated because youll have no broker fees to cover. When investing in one of the more expensive solar panel systems, this can make a real difference.

Your local installer can give you a free quote on your bespoke system, but for a ballpark figure, a solar panel system to support the average family of three people would cost around £6,000.

How Does Weather And Climate Affect Solar Panels

If theres enough light to see, solar panels will generate electricity but inclement weather does affect solar panel output and efficiency. Unsurprisingly, solar panels perform best in the summer when the days are longer and light is strongest but also work well in the winter because their efficiency goes up in cooler temperatures.

Do Solar Panels Increase The Value Of Your Home

Solar panels can increase the value of your home as they make your house more energy-efficient. This is one of the home improvements that make your home more attractive to potential buyers, as the new owners can enjoy the same benefits of reduced electricity bills.

Naturally, the size of the solar panel system will affect just how much the value will increase, and bear in mind that different families will have different energy expenditure habits. That means that one system may be adequate for some families and inadequate for others.

For some buyers, solar panels are not a valuable addition to a home, so it does depend on personal preference.

When bringing a solar panel on camping trips, youll want to look for something lightweight, durable, and powerful enough to charge your cameras, portable speakers, lights, and other camping gadgets. The Eco Flow Portable Solar Panel has two different sizes: 110 watt or 160 watts with a high conversion efficiency of up to 22%. It also includes an MC4 cable connector and carry case.

If your camping trip takes you across rivers or kayaking across lakes, the panel has an IP67 waterproof rating, so it can hold up to Mother Nature better than many of its competitors. The unit consists of four folding panels and weighs around 14 pounds.

How Long Does It Take For Solar Panels To Pay For Themselves

The answer to this question depends on a number of factors, including the number and type of panels installed, as well as the installation fee, which will vary on the type of house and location. However, a good rule of thumb is that solar panels take 11-14 years to pay for themselves. Well, that was before the cost of living crisis which has seen extraordinary increases in our energy bills. According so some calculations, that estimate has come down to as low as four years.

Disadvantages Of Solar Panels

• Specific solar panel placement

High Initial Costs

Investing in solar panels can be expensive. You can expect around £5,000 to £10,000 in up-front costs. Although you can earn money back on your solar panels by exporting energy to the grid, the high set-up costs can be difficult to meet for some.

Significantly More Efficient During Daytime

Solar panels are dependent on sunlight. Although they do not require direct sunlight to work, they lose efficiency if they are not fully exposed to sunlight. In addition, they cant produce energy during the night and are less effective during dark winters.

An effective solution to this is to switch to the main power grid at night. Alternatively, homes with a grid-independent system can store energy in solar batteries during the day, which can then be used at night.

Solar Panel Placement

Inaccurate placement of solar panels can majorly reduce the effectiveness of electricity generation. If you live in an area surrounded by large buildings or tall trees, the efficiency of your solar panels will be very limited.

Ensure there are no buildings or trees blocking sunlight, and always clear branches and leaves from the panels.

Best For Lightweight Panels: Panasonic Hit N340

Panasonic doesnt manufacture its own panels anymore, but its subcontractors still churn out its excellent products, including the tiny, lightweight HIT N340.

Not only is it just 19 kg, its also 1.7 square metres making it 16% smaller than the average panel in our investigation.

Its heat resistance is also fantastic, and its warranties are solid. The only drawback is that its not as powerful as the other panels on this list.

How Energysage Developed Its Best Solar Panels Ranking

When searching for the best solar panels for your home, you should consider a panels performance, quality, durability, and warranties. There are three major technical specifications that can help you as you make your decision: panel efficiency, temperature coefficient, and the materials warranty. To develop our ranking of the best solar panels for your home, EnergySage evaluated these metrics for all of the solar panels offered by the top manufacturers in the EnergySage Marketplace.

Keep in mind that while not considered in this rating, solar panels also come with a 25-year performance warranty. Manufacturers typically guarantee that their panels will produce electricity at 80-90 percent of their original output at the end of that warranty period.

What Impacts Solar Panel Performance

Solar panels can vary quite a bit in their overall performance and productivity. There are a number of specific factors that can impact how your solar system performs, including:

• Orientation: When your home solar system is designed, your installer will be careful to position each panel in a way that maximizes its exposure to sunlight. If the orientation is even a little bit off, it can compromise the efficiency of your entire system.
• Weather and sun exposure: If you live in a part of the country that doesnt get consistent sunlight, or if your solar panels are often under cloud coverage, youre not going to produce as much clean energy for your home.
• Cleanliness: While solar panels are fairly low maintenance, you may occasionally need to wipe them down, especially in the aftermath of an intense storm or during a season like spring or fall when there is pollen or falling leaves that can block your panels. If panels become covered with grime or debris, they may not be able to absorb as much sunlight.
• Shade: Keep in mind that any shade cast over your roof is going to impact the efficiency of your solar panels. If your house is surrounded by tall trees, for example, that could impede solar production.

Solar Panel Types By Power Capacity

Monocrystalline cells have the highest power capacity, thanks to their single-crystal construction that allows a higher output rating in a smaller package. Most monocrystalline panels can generate up to 300w of power capacity.

Recent advances in solar technology have allowed polycrystalline panels to bridge the gap. A standard 60-cell polycrystalline panel is now capable of producing between 240-300w. However, monocrystalline panels still beat polycrystalline in terms of power capacity per cell.

Because thin-film panels dont come in uniform sizes, there is no standard measure of power capacity, and the capacity of one thin-film panel will differ from another based on its physical size. In general, given the same physical footprint, conventional crystalline panels output more power than a thin-film panel of the same size.

Solar Energy Performance Guarantee

In addition to covering any defects with the Solar Panel Warranty, manufacturers also provide a Performance Guarantee for their products.

At this time, most manufacturers guarantee a certain level of production over 25 years, but some are now guaranteeing over 80% production for 30 years.

If you want the best residential solar panels, be sure that your evaluating the level of production that the manufacturer is guaranteeing.

Typical Performance Guarantees are in the 80-85% range after 25 years. The very best solar panels are guaranteed to perform at least 90% of rated power output.

Please note that the same exclusions from the Solar Panel Warranty also apply to the Solar Energy Performance Guarantee. So if your panels have been caked in dirt and are under-producing, the panel maker has cause to exclude your system from their guarantee. In fact, most manufacturers release their panel warranties and performance guarantees in the same document.

Do Solar Panels Void My Roof Warranty

When you install solar panels on your roof, your roof warranty will indeed be voided for the section of your roof that is housing the panels. However, your solar energy installer should provide you with a new warranty covering this section of your roof. Its important to ask about this when you seek a free quote for your local supplier. Likewise, you should also check the details of your existing roof warranty before making any decision.

The Experts Top Premium Panels: Panasonic Lg And Sunpower

Premium solar panels are panels that are high quality and boast top-of-the-line specifications – along with a higher price tag. Our experts top choices in the premium solar panel category are Panasonic, LG, and SunPower.

All three companies manufacture high-performance modules with superior workmanship, higher efficiency ratings, better temperature coefficients, lower degradation rates, and market-leading 25-year product warranties.

Panasonic and LG solar panels are our experts top picks. Besides being excellent panels, they win points for being produced by massive conglomerates. Both companies are known for their high manufacturing standards, and are almost certain to be around to honor any warranty claims down the line. This means they are Tier 1 solar panel brands.

Learn more about the differences between Tier 1 and Tier 2 solar panel manufacturers here.

Comparing the two, the experts says that the Panasonic solar panels have a slight edge in terms of specs, while LG panels have a small cost advantage.

Meanwhile, SunPowers panels are actually the very best in the market in terms of efficiency and performance – even better than Panasonics and LGs – yet the brand only ranked #5.

Why? Well according to the experts, SunPower’s ranking suffers due to its troubled financial position, coupled with its very high price point. We’ll be keeping an eye out to see how things change as SunPower spins off its manufacturing business into a new entity called Maxeon Solar.
