3 Solar Energy Secrets You Should Know

 

Solar energy is becoming one of the main renewable energy sources for cheaper and cleaner energy. As solar energy grows, more and more people are also asking for the benefits it can give, but the problem is there are still a lot of misconceptions on what solar energy can really do for you.

Many people can give you a list of the benefits in switching to solar, but there are only very few people who can tell you these solar energy secrets that we are about to uncover.

Let’s start!

 

Solar Energy Secret #1:  Poly is a wiser choice than Mono

Yes, you read it right.

Well, we knew that the larger and purer the crystal is, the more efficient the solar cells will be. As a result, monocrystalline modules are around 10% to 15% more energy efficient than their poly counterparts.

Polycrystalline modules, on the other hand, were often thought to be inferior to mono solar panels because they are less efficient.

But, here’s the catch: because of the cheaper process, it costs around 20% less to create solar modules with monocrystalline structures. More than that, poly modules have been improving their performance constantly in recent years, pushing the standard to greater limits.

You might already hear someone says:

monocrystalline solar panels have the highest efficiency rates since they are made out of the highest-grade silicon, and the efficiency rates are typically 15-20%”.

Well, mono by nature is most efficient than poly, but at a module level, a 250W Poly or Mono panels will perform somewhat the same.

If cost is your major concern and you want to pay as little as possible for installation, then poly is a wiser choice than mono. You won’t get the same efficiency as with monocrystalline modules, but you’ll reduce the initial costs dramatically.

Just remember one thing: Being More Efficient Does Not Mean It Will Produce More Power (kWh) ).

 

 

Solar Energy Secret #2:  There are solar panels that work well in shades

We all know that if the panel is covered with shades, it will drastically affect its performance.

But what if we tell you that there are panels that work well even if it was covered in shades.

Yes, that kind of panel exists.

One of the leading Tier 1 solar company Seraphim, solved the problem of shades by making the Blade Series.

The Blade Series boasts two identical parts, each comprising cells that are half the size of ordinary solar cells. Instead of 6 internal strings of cells, the series has 2 X 6 shorter ones – resulting in dramatically improved performance.

Six strings are connected in a series per block, and the two blocks connected in parallel. A split junction box is positioned in the middle of the module to the output current.

In traditional modules, the power of the entire module is significantly reduced even with partial shading. However, for the Blade Series, partial shading will only affect the half of the shaded module – the other half will continue to operate at full capacity.

Solar Energy Secret #3: Solar Energy is cheaper than you think

Solar PV is becoming cheaper than ever. Almost every month, a new industry “low” is set and broken.

The latest example occurred this week when a Nevada solar auction sold at a rate of $23.76 per megawatt-hour in a 25-year contract at the Eagle Shadow Mountain Solar Farm, according to Earther. The facility is expected to be ready in 2021, and it breaks a one-week-old record for the country’s cheapest solar project.

According to Green Tech Media, this is just another sign that the solar energy train isn’t slowing down. Solar markets analysts say prices are dropping even faster than expected, and it’s allowing solar projects in sunny, arid parts of the country to reach agreements at record-low prices.

For comparison’s sake, the U.S. Energy Information Administration anticipates that the levelized cost of electricity (LCOE)—the true cost of energy before factoring in subsidies—for common energy sources in 2022 will be (per kilowatt-hour):

  • Coal: 11.91 – 13.01 cents
  • Natural Gas (Combined-Cycle): 4.9 – 5.01 cents
  • Natural Gas (Combustion Turbine): 8.51 – 9.87 cents
  • Nuclear: 9.26 cents
  • Wind (Onshore): 5.91 cents
  • Hydroelectric: 6.17 cents
  • Geothermal: 4.46 cents
  • Biomass: 9.53 cents
