Top 8 Most Efficient Solar Panels for Your Home

The efficiency of solar panels is based on a percentage rating. This indicates how much power is being released or put out in relation to the surface area of the panel, along with input from the sun. The standard rating is of at least 16.5. The smaller the surface area, the more efficient the panel. Consequently, fewer and more powerful panels is the ideal setting.

Though the surface area is important, the actual finished size of a panel is important. This is because it helps determine which panels are suitable for positioning on a rooftop or other areas for exposure to sunlight.

Solar panels can be a costly investment.  Therefore, it is imperative that they not only be the most efficient solar panels but must also have durability, sufficient wattage power (230 watts minimum), adaptable dimensions and backing by reputable and long standing companies.

Solar panel energy companies that truly believe in the value of their panels will stand behind them and offer precise and favorable warranties as well as follow-up customer support.

Rundown of the Most Efficient Solar Panels

1. Kyocera Solar Panels KD315GX-LPB

Kyocera’s KD315GX-LPB solar panel is one of the most efficient solar panels as it is attractive, high quality and provides a 16 percent solar efficiency. This produces a significant amount of energy to a home. It has a black frame and is comprised of polycrystalline (aggregates of crystals) component.

As rooftop panels, they generate 315 watts of power with a maximum voltage of 39.8 and a maximum power current of 7.92 amps. Each panel holds 80 cells. The company has specific warranties on the panels as well as workmanship for the first five years of use and extended warranties on the assurance of power output.

2. Canadian Solar Panels CS6X-305M

The Canadian Solar MaxPower CS6X-305M is a sturdy panel with a solar efficiency of 15.9 percent and is one of the most efficient solar panels available. The panels are monocrystalline (one crystal) and produce a top power of 305 watts, a maximum voltage of 36.6 volts and a current of 8.33 amps. Each panel contains 72 solar cells. The panels themselves are tall and narrow in width. As a result, their appearance separates them from other solar panels, yet they are appealing to consumers.

3. Grape Solar Panels 390W

Grape Solar’s 390W panel is an anodized aluminum frame panel that has a solar efficiency of 15.21 percent, which is a suitable rating. Its module cells are monocrystalline with a tempered glass cover. The power output is a maximum 390 watts, a power voltage maximum of 49.4 volts and a power current of 7.92 amps. There are specific warranties that cover materials, workmanship and power output assurances that cover 10 to 25 years.

4. Grape Solar Panels 250W

The Grape Solar 250W solar module is another high-quality panel. It contains anodized aluminum frame panels with tempered glass covers and modules that hold 60 cells each. It has a solar efficiency percentage of 15.1, which is a good rating for solar panels.

Each module offers a maximum power of 250 watts, a top power voltage of 30.8 volts and a power current of 8.15 amps. These particular modules also have specific warranties offered through Grape Solar that cover materials, workmanship and power output assurances from 10 to 25 years.

5. Suntech Solar Panels STP255S-20/Wdb

Suntech’s STP255S-20/Wdb panel framework is made from anodized aluminum alloy with 60 cells per module, and a covering of tempered glass. It has a solar percentage rating of 15.7 percent, which is a good rating. It has a maximum power wattage of 250 watts, maximum power voltage of 30.8 volts and a maximum power current of 8.28 amps. Suntech offers warranty on workmanship and the panels as well as power output from 12 to 25 years.

6. Samsung Solar Panels LPC250SM

Samsung’s LPC250SM panel is a solar panel with a sufficient solar efficiency output of 15.62. The modules consist of tempered glass covers and alloy frames made of anodized aluminum. The panels contain 60 Monocrystaline cells. Maximum power output for each panel is 250 watts with 30.5 volts at maximum levels and 8.2 amps of current. Samsung offers a limited warranty on materials and workmanship (five years) and power output assurances from 10-25 years.

7. Sharp Solar Panels ND-Q245F

Sharp Solar Panels ND-Q245F, in comparison to the other panels reviewed, are not the most efficient solar panels. They have a rating of 15 percent, which is fairly standard. Their lower rating is offset by their durability, resiliency and limited maintenance.

They have a maximum power of 29.3 volts, power current of 8.36 amps, 245 watts of energy output and 60 polycrystalline silicon cells that are covered with tempered glass. Sharp provides a warranty for materials and workmanship of ten years and a 25-year limited warranty for power output assurance.

8. Lumos LSX Solar Panels 250-60M

The Lumos LSX250-60M solar panels have a different appearance and design than conventional solar panels. They are frameless, monocrystalline glass-like modules with 60 cells per module that bring a whole new look to a rooftop. Even though they are not the most efficient solar panels, they still carry a 14.68 percent efficiency percentage. They have a maximum power out of 250 watts, with maximum voltage of 30.1 volts and maximum current of 8.31 amps. Lumos provides a warranty of 5 years of coverage for materials and workmanship.

When considering the most efficient solar panels, keep in mind a few important factors before jumping on the solar express. Longevity is important. Fly-by-night companies won’t be around to honor warranties, so use caution. Remember the wattage figure as well and the limited number of panels to utilize roof space more effectively. Most importantly, keep in mind the efficiency percentage rating for energy saving benefits.

Solar panels are a great investment and add value to a home. Seriously consider the advantages of solar energy and what you will save. It’s a great time to go solar. You, too, can be part of the new energy wave with just a little research on the most efficient solar panels available today.
