The Relationship Between Solar Energy and Solar Cells
The solar energy is the power of our life on the earth, it used for many different aspects thousands of years ago, to extent that we can Not really live without it. The sun provides huge power, and its output energy in one hour is sufficient to power our planet entirely for one year. Actually, the solar energy is mainly received in two kind of forms: heat and light.
7 Key Factors About Solar Photovoltaic Systems
The solar panel is the first working part of solar photovoltaic system to converts the sun light to DC electricity. It is made of silicon element, and the silicon is abundant element on the earth, it represents approximate 30% of the earth crust, and it’s the seventh common element on the world.
Evolution of Solar Micro Inverter
The micro grid inverter is a small plug and play device which is usually connected to one solar panel/module to convert DC to AC electricity, and that is its mainly difference from other solar string and central inverters which can be connected to multiple solar panels. In addition, the output from several micro-inverters are always connected together to electrically feed one electrical grid panel.
What is the Future of Solar Energy?
Let us look at cost evolution trajectory, as the prime component of the solar system is the solar cell which made mainly from semiconductors (silicon material), and as these semi-conductor’s material price has fallen down, also by deep looking on its cost reduction trajectory and monitoring solar panels prices development, the solar specialists confirmed that solar energy costs have fallen by around 18-22% (20% in average) in recent years.
4 Uses of Solar Energy
You may imagine that this may not be fetched in the future, but we confirm you that it will be reached in very near future, as simply many of these technologies are actually under trails in laboratories, and the manufacturers/expertise’s have already achieved a great progress. The one obstacle in such progress way, is the cost barrier, but this will be surely covered and returned back with high profits after the implementation of these technologies on the land, and to be used in the market. From the history, it is proven that solar panels costs have fallen dramatically although of glitches and bumps solar industry faced, the solar panel price has fallen from 6USD per one watt in 2007 to 1USD per one watt nowadays, and the analysts expect more cost reductions will be achieved in very near future with more researches taking place, of course this will encourage using solar industry in all our life styles, so we confirm that solar will be the future of all the human beings.
Site Inspection before Installing Solar PV System
Do you accept to receive a quote for installing a new bathroom in your house via phone call without the installer visit to your house? Of course, the answer is No. That is same like installing a solar photovoltaic system on your house roof, it’s a must for the solar installer to come the house and check/inspect all your private circumstances and conditions, and absolutely not sufficient to get a quote via phone or internet email.
Everything You Need to Know About STCs
It's a tradeable certificate represents CO2 emission saving resulting from installing a small scale solar system, its issued and awarded from a government body, called clean energy regulator. In other word, it's a measure of how much CO2 emission your solar system installation will save. When your small scale solar system installed, calculations will be done by clean energy regulator to indicate how many STCs can be created over the whole life time of your solar system, and of course this is also a measure of how much renewable energy your solar system will generate.

Net Metering vs Gross Metering
In gross metering, the whole solar system generated electricity will go to the grid, and you will get paid for it as a form of credit shown in the electricity bill. In other word, we can say that in gross metering, it measures the entire output energy separately from your energy consumption, and you pay for electricity bill (energy consumption), and get paid for exported energy, in where no relation in between them “no net”.
8 Tips Before Installing Solar PV Systems
After installing the solar system, your electrical energy meter will need to be changed to accommodate the new installation, and the question is; who will be responsible of such changeover? Is it you or solar installation company or electricity company? This point must be clear from the beginning, and usually the solar company will do that job under the supervision of the electricity company. The solar system rebates that you will get from the solar installation company as a result of selling your STCs certificate is an important point to be discussed, so you will be aware of how mush discount you will get from such STCs certificates.
How Solar PV Systems Affect House Value
What aforementioned assumed that you own your photovoltaic system, and do Not lease nor have it under a purchase agreement. As if you do not own the solar system, then you have to pay for it when the time comes to sell the house, but in that case you will lose much, because you will pay the whole price to the solar company early, and only the other option is to try convincing the buyer to take the contract with the solar company over. Mostly, the new house owner will agree to take the contract, but if not, then you will get in stuck.

The application of solar system

Checklist Before Buying a Solar PV System
What will be the expected annual generated electricity (kwh) form your solar system as a whole? And will your solar system installation company be ready to provide written statement about that. That is the strict performance indication, and if the solar company provide such statement, then be rest assured your system will be of high performance and efficiency. The solar installation company has to agree with you before installation who will be responsible of repair and replacements costs if needed. This point should be clear and documented.
How do Solar Photovoltaic System Produce Electricity?
The most important step is that you have to make sure that your solar company will be in charge of installation, installing metering device, and to connect solar photovoltaic system with the grid. Solar company invoice you have to pay should have the prices of these tasks and all relevant works. However, in general, the electricity company will supply such solar energy meter and install or supervise on its installation. After installing the solar energy meter, your solar photovoltaic system is ready to run and produce electricity.
Solar Energy Advantage and Disadvantage
The sun is the greatest power source at all, as the sun energy we receive in one hour could cover our global energy needs for an entire year, but unluckily we are not able to harvest a fraction of this energy! Through solar panels we are just able to convert very small amount of sun energy to electricity. However solar panels technology has been developed in recent years drastically, providing higher efficiency solar panels, and we are sure there will be continuous improvements. Let’s us summarize the pross and cons of the solar energy.
