Solar panels regenerating power

Australian engineers have taken us closer than ever before to the theoretical limits of sunlight-to-electricity conversion, by building RENOGY 20 AMP MPPT SOLAR CONTROLLER that can harvest an unheard-of 34.5 percent of the Sun's energy without concentrators .
The previous record of 24 percent was held by a large, 800-square centimetre solar cell produced by a US company, but these new RENOGY 20 AMP MPPT SOLAR CONTROLLER aren't only more efficient, they also cover far less surface area, which means they're going to make solar power even cheaper.
"This encouraging result shows that there are still advances to come in photovoltaics research to make solar cells even more efficient," said one of the researchers, Mark Keevers, from the University of New South Wales (UNSW) in Sydney. "Extracting more energy from every beam of sunlight is critical to RENOGY 20 AMP MPPT SOLAR CONTROLLER the cost of electricity generated by solar cells as it lowers the investment needed, and delivering payback faster."
This UNSW team is the same one that set a new solar conversion record back in 2014, by using mirrors to concentrate sunlight and achieve 40 percent efficiency. But this new record is even more impressive, because it didn't involve any concentration, and it was something engineers hadn't expected to achieve for several decades.
"A recent study by Germany’s Agora Energiewende think tank set an aggressive target of 35 percent efficiency by 2050 for a module that uses un-concentrated sunlight, such as the standard ones on family homes," said one of the researchers, Martin Green. "So things are moving faster in solar cell efficiency than many experts expected." 
The new cell is only 28 square centimetres (11 square inches) and it works by splitting the incoming sunlight into four bands.
The infrared band of that light is reflected back towards a silicon solar cell, and the other three bands are directed into a three-layer, new type of solar cell, made of: indium-gallium-phosphide; indium-gallium-arsenide; and germanium.
The sunlight passes through each of these layers, or junctions, and energy is extracted by each at its most efficient wavelength. Any unused light passes on to the next layer, and so on, to squeeze the most out of every single beam.

What Features You Should Look for in a Web Hosting Service for Business



If you search for a web host online, you’ll encounter pages of results that sell domain names. Choosing a host becomes a matter of thorough research to ensure that you receive the best deal for your small business. Your business web page is provides a virtual window to your business. Having a web page that loads very slowly or has errors can have negative impact on your business brand. That is why you need to ensure your web hosting provider has certain key features. Below we have listed them to assist you with your search.



Minimal Downtime


Web hosts that have a strong reputation in the industry will advertise their uptime. Ideally, you want an uptime that’s in the 90 percentile range. This value tells you how often the site goes down for technical difficulties. Hosts that don’t have an uptime advertised on their sites may have poor track records. Ask about current uptime values so that you’re aware of the service quality. The host may need new hardware or updated software to keep up with today’s online needs.

How to Stop Treating Your Small Business Like a Hobby



Sometimes running a small business may seem much like enjoying our hobby. They are often built from the passion where we like to spend our time doing, and it can be easy to see small business as an offshoot of our interests, instead of as a serious money-making venture. But this can be disastrous, as too many folks end up sinking hard-earned capital into their small business to keep it afloat as it is their pet project. But the clue is really in the name ‘small business.’ That means no matter the size of the company that you are running you are aiming to make a profit. So, you need to stop treating it as a hobby and get serious. Read on to find out how.



Make a plan


The first thing that you need to do to get serious about your small business is to think about where you see your business going in the next 5 years. You need a plan, and not just one written down on the back of a restaurant napkin sort of plan, a proper one.

One that has achievable and measurable goals, and all of the steps that you need to complete to get there. Business are not static things, and you certainly want to ensure that you are making enough profits to make them viable. So get a plan to do this in order, before you move on to any other stage.

Doing Business in the US? What You Should Know



For many small business owners, being able to move their operation to the US is the holy grail. The market liquidity, the generous tax incentives, and the idealized “American Dream” attract countless business owners and investors to the nation. Although the US has been the home of some truly inspirational success stories, it’s also driven promising companies into the ground. If you’re planning to grow your business in the US, here are some essential things to know…



American Businesspeople are Fickle


In the states, when a business owner needs something from someone else, they’ll tend to be very forthcoming, friendly and accessible. However, when they no longer need anything from the other entity, it’s common for them to do a full 180-degree turn, and become unresponsive to communication and proposals. Yet, if they suddenly need something again in the future, they’ll come running back with the same warm demeanor, as if nothing happened. You’ll need to adapt quickly to this culture if you don’t want to be taken for a fool!
