Solar technology has come a long way. From the types of solar panels to the various inverters, it’s never been a better time to make the switch to a solar powered home or business. But keeping up on the latest technology is a big part of being able to make a well-educated decision when a solar company comes knocking on your door, asking you to sign with them.
We talked with Kelly Curtis, Director of Operations at Solaroo Energy on two of the newest solar panels to hit the Utah market. Here he discusses with us which products and brands they are, as well as breaking it down to see the advantages and features.
“It always helps to be ‘in the know’ when you are discussing solar panels with any salesperson. We are big on education not only on the basics of a solar system but on the types of products available to our customers as well. I’m about to get really “nerdy” in this article, so if I’ve by chance managed to confuse anyone, please feel free to call us at Solaroo Energy to have one of our experienced solar analysts can assist you.”
Panasonic HIT N-type cell
Panasonic has recently introduced an N-type cell using ultra-thin amorphous silicon layers. What the heck does that mean? Well, it means the following:
Ultra-high efficiency – Panasonic recently introduced cell is one of the top performing cells for efficiency . It means that you will produce more power in the same amount of space, which is a great solution for roofs with limited productive space.
High-temperature efficiency – Heat will make a solar module less efficient. The hotter it gets the less maximum power your panel will produce. With Panasonic’s double layer of silicone, however, the N-type cell performs better with increasing temperatures than standard mono or poly cells. Translation: more power in the summer when the sun is up the longest.
Light capture – Electricity is made in the solar cell by capturing photons in the sun’s rays. Panasonic’s unique pyramid structure capture’s more sunlight by reflecting the photons inside the cell instead of reflecting them away from the cell, as standard cells do. Translation: better production in low light conditions and more photons in normal conditions.
The Panasonic HIT module is definitely top of the line but also carries a price tag above a standard module as well.
Mitsubishi Diamond Premium
Although not as efficient as the Panasonic N-type, Mitsubishi boasts new features that are also unique at a more affordable price tag.
Lowest warranty claims – Mitsubishi has warranty claims on their panels globally at a rate of four panels per million, which is really, really low. Compare that with U.S.-made SolarWorld’s rate of 17 panels per million. Also really good, but more than four times the amount.
Quality construction – All you have to do is touch and feel a Mitsubishi panel to see the quality. Anodized and clear-coated frame for rust proofing, support bars instead of adhesive, screws instead of clips, more bus bars, sealed and potted junction boxes — it is no wonder that their warranty claim rate is so low.
The details – Mitsubishi does not skimp on the small things — water drainage channels to keep the panels cleaner, split cells for less on panel shading issues, and 100 lead-free free solder. Translation: it might be the best built in terms of quality of construction in the market.
