SOLAR PANELS IN THE MARKET

Post by : Sam Allcock on 14.08.2020

Shopping for the best solar panels could be, at times, considered a daunting challenge. This is attributed to the many available solar panel brands in the market. But it does not have to be a head-scratching task with all the reliable information available today. There will always be hundreds of solar panels and solar-related equipment in the market to choose from every time.

A few factors ought to be considered when purchasing solar panels. Energy-efficiency, reliability, durability, fair electricity bills, vertaa sähkö and premium protection are the key factors to put into consideration. The best solar panel selling brands have a stellar 25-year warranty attached to their products because of the high efficiencies.

Monocrystalline solar cells are used to make almost if not all best solar panels. Unlike polycrystalline, which is made up many silicon fragments melted; monocrystalline cells are of a single silicon crystal. This means that the cells offer a higher efficiency in converting sunlight and rays into electricity which is also aided by the sleek black tint. You ought to keep in mind that monocrystalline cells made solar panels have a slightly higher upfront price tag attached. Furthermore, value is realized in reasonable expenditure.

Let us take a ride through some of the best solar panels in the market, and as well answer some solar panels questions that linger in the mind of every potential buyer.

Can Solar Panels Work at Night?

Researchers are on the road to discovering and tapping into the full potential of solar panels. The inability to generate power at night is a mystery that is about to be unravelled. But how? – Through tapping into the universe infrared light.

The panels function by use of photovoltaic cells to absorb the sun’s heat and generate energy. Anti-solar panels are pointed toward the ground as soon as the sun sets to arrest the invisible infrared light on earth ground. This is aimed at battery use reduction during night hours as well as minimization of natural gas generating plants.

The anti-solar panels could be designed to generate about twenty-five percent of the electricity in the night hours that a typical solar panel produces during sunlight hours. Development of a solar panel that could work at night is also underway.

Best Solar Panels in the Market

In most cases, the best solar panels are classified by temperature co-efficiency, solar panel efficiency, and materials warranty.

Solar Panel Efficiency

Solar panel efficiency is defined by how effectively your panel can convert sunlight/sun heat to usable energy. Higher efficiency rating is what every consumer looks for since this implies that, the higher the efficiency rating, the higher the ability of the solar panel to convert more of the captured sunlight into energy.

Research and experience, have it that the best solar panels available in the market categorized by solar panel efficiency are:

  • SunPower’s A-series solar panels. SPR-X22-360-D-AC is their most popular solar panel
  • These kinds of solar panels are twenty-three percent efficient at their full capacity.
  • LG solar panels which bear module efficiency of twenty-two percent at maximum
  • REC Group solar panels that operate at 21.7% module efficiency
  • CSUN solar panels that operate at 21.2% maximum module efficiency
  • Solaria solar panels are also among the best according to solar panel efficiency operating at 20.5%

Temperature Coefficient

temperature coefficient dictates how your solar panel performs in less-ideal conditions. Mostly determines how much or less does your solar panel perform during abnormal rise temperature increase (most notably during hot summer). In typical situations, solar panel’s production decreases by every degree above 250 C or 770 F. the lower the temperature coefficient, the better the solar panel.

The best solar panels categorized by temperature coefficient include:

  • Panasonic solar panels with a temperature coefficient of -0.26
  • REC Group solar panels bearing a temperature coefficient of -0.26
  • Solartech Universal solar panels with a temperature coefficient of -0.26
  • SunPower solar panels are also among the best with a temperature coefficient of -0.29
  • LG solar panels with a temperature coefficient of -0.30

Materials Warranty

Materials warranty, commonly known as equipment warranty or product warranty, protects the buyer against machine failure caused by manufacturing defects or environmental factors. The standard equipment warranty is usually ten years, but the best manufactures go beyond ten years to offer fifteen to twenty-five years of warranty. The best solar panels manufacturers categorized by materials warranty include:

  • Mission Solar panels with guaranteed 25 years
  • Q CELLS Solar panels offering 25 years of warranty
  • Axitec manufacturers providing a guaranteed 25 years
  • REC Group – 25 years
  • SunPower solar panels 25 years of materials warranty
  • Panasonic solar panels with guaranteed 25 years
  • LG solar panels with 25 years warranty
  • Solaria solar panels with 25 years of materials warranty
  • Silfab manufactures solar panels of 25 years warranty

What happens to solar panels after 25 years?

Solar panels are expected to work within 80 -90% of their original energy output. After twenty-five years of their functioning, the useful economic life begins to degrade slowly.
