The Tesla battery is by far the most exciting product release in the retail market – and not just because of the passion of their charismatic CEO Elon Musk. Here are some things you need to know about the new Tesla battery – the Powerwall.
The Heliac solar foils consist of a series of polymer sheets that are nano-structured and micro with Fresnel lenses. This is yet another technology created on the path to making solar power cheaper than fossil fuels. Check it out!
Another Nanotechnology project in the solar industry. as far as making solar more efficient, smaller and more affordable, many out there in the science community believe that nanotech holds the keys to such advancements. Jonathan Strickland more about how, with more understanding, nanotechnology will reshape the way we make solar panels.
A team of scientists at Michigan University has created a clear surface that is able to collect solar energy, the surface is completely clear and opens up many possibilities for solar design in city spaces.
Thinking of investing on solar panels to start cutting down your utility expenses? If you want to see favorable results within a given period, then you need to buy high quality solar power systems that yield the best returns on your investment. So, learn more about the nitty-gritty when buying the right solar electric system that suits your budget and needs.
How Efficient Are the Solar Panels?
To get to the bottom of this, you need to check the material used in the solar panels, which should be high quality silicon or monocrystalline. Solar power systems with high efficiency level are made from expensive and single chunks of silicon that are capable of producing more power per panel. On the other hand, low-cost systems are manufactured from polycrystalline, which are not as efficient in generating electricity as panels made of pricier and higher quality silicon.
Although your initial investment may seem lower when you go for cheaper solar panels, you may end up spending more in the long run due to greater negative power loss. So, it is a much better decision to think about long-term benefits to avoid any regrets eventually.
What’s the PTC Rating?
PTC or PVUsa Test Conditions is the rating that serves as the highest benchmark for solar panels. All solar electric systems manufactured in the United States must have their specific PTC rating before they are made available in the market. The rating also serves as a means to protect cosumers from buying low quality panels that fall below their standards.
Generally, the higher the PTC rating of the system, the better it is. It does not matter whether the STC or Standard Testing Conditions rating is high or low, since the main basis is on the PTC rating. If you rely on a system with low PTC rating, you may end up buying more panels in the future, which can cost you more than investing initially on panels with higher ratings.
Does It Come with a Warranty?
As when shopping for any appliances, a waranty is an important feature of solar panels. Although solar power systems can last for over 25 years, it helps to have a lifetime warranty for your panels in case there are factory defects. Fortunately, most manufacturers offer warranties to customers, and that should save you from any hassles when you need to have the system repaired. Just be sure to buy from a reputable manufacturer that is well known for its quality products at reasonable prices.
Can I Use Solar at Night?
Not traditionally, however with battery technology advancing at a rapid rate, this option is becoming very affordable for homeowners – particularly with options like the Tesla Powerwall:
