SOLAR ENERGY: The Power that lit the World

Updated on May 29, 2016

Today, Electricity is the most basic need of human beings because everything that we use runs on electricity. Either it is for work, travel, entertainment everything is electrified. So, we can conclude the importance of this human created miracle. Production of electricity is the most controversial topic today. Every countries around the world are working on it. But regarding the energy harnessing process, we stick to the same old technique of using turbine and then rotate it using steam or anything and then convert that rotating energy into electric energy. But this process is very costly, and having many drawbacks.

Now, come to the types of energy we use. 80% of energy we produce today came from fossil fuel, which is, as we know are non-renewable source of energy and cannot regenerate, if used once. Solar energy is conventional source of energy which is infinite and cannot be vanish. Every second, our sun produces enough energy to sustain Earth's need for 500,000 years.

Benefits of Solar energy

1. Solar energy is Eco-friendly- As the technology advances, Environment awareness has become the trending topic altogether. Solar energy is entirely pollution free source of energy that causes no harm to the environment.

2. Easy to Install: DIY solar panel for home use has become popular mostly because of easy installation. it is easy to install and take small space and time.

3. Long duration of working: If install once, it lasted for more than 30 years. Which makes it more beneficial over other source of energy.

4. Less maintenance: It do not need workers to take care of every time, Sun is the only care taker of the DIY solar panel for home.

Solar Panel

Solar panel is a system which capture the sun's energy and convert it into electricity. It contains solar cells, or Photovoltaic cells, which are arranged in grid-like patterns on the surface solar panel. These cells collect sunlight during daylight and convert it into electricity. These cells are typically made up of Silicon.

Solar panel for home

Despite being the Conventional and eco-friendly source of energy, One of the most convenient and yet important part about solar panel is that you can install it in your home. DIY(do it useful) solar panel for home is the emerging concept of installing solar panel on your home to produce electricity for domestic purpose.

What do we need?
There are some parts that we need to install diy solar panel at home:

1. PV Panels: it collect energy from the sun and convert it into DC current.

2. Power Inverter: it convert DC current that we have collected into AC current for domestic purpose.

3. Net meter: it connects your house to the grid and thus measuring the power transfer.

4. PV Disconnect: it cut off the power.

5. Home breaker's box: it is where the solar energy connects to the home.

Government scheme

Government around the world are working to promote the use of solar panel. An initiative called 'Feed-in Tariff(FiT)' started by government that grant offer for solar panel for home. Some companies used offer to install the free solar panels at home for people, that would be free of cost but you didn't get all the benefits of the solar panel. though you can save money for electric bills.
Government have to work more on this field and supply free solar panel at home to promote it more and more and everyone can use it.

      Thank you for answering my questions! Very thorough answers I might add. However it makes me believe they have a lot more work to do on development of solar panels.

      So the prohibiting factor seems to be the cost right now but from what I've read "significant cost reductions may be required to make [photovoltaic] competitive at the very substantial penetration levels envisioned in many low-[carbon dioxide] scenarios" http://www.washingtonexaminer.com/mit-solar-will-t...

      Although solar may appear to you to be our only hope for future energy, future being 100 years from now (or more). I say that because I think we are still very far from having the efficiency and affordable cost that will compete with current (and or future newly developed) modes of energy. It would be nice to capitalize on the free energy supplied by the sun beyond the methods used by our creator but I think we are very far from an affordable solar solution taking into account all the cost ramifications that come with it. We are far from being there, developers keep begging for more government money to get us there and guess what, governments (worldwide) are actually broke and as interest rates rise there won't be enough money to service their debt let alone finance all they are committed to.

      hello tsadjatko, firts of all thanks for stopping by. As you said about the problems regarding solar panel, I am agree with these are somewhat correct there are some problems with the solar energy but still it would be the best source of energy for us. Despite of pointing out the problems of it think over its solution, benefits and most important its necessity. Believe it or not solar is our only hope for future energy and we should work on it as much as possible and first step is to make it popular.

      And your answer to the question is that, Photovoltaic (PV) modules which is the unit of a solar panel typically come with 30 year warranties that guarantee that the panels will produce at least 80% of the rated power after 30 years of use. The general rule of thumb is that panels will degrade by about 1% each year. Crystalline silicon modules located in extreme climates showed high degradation rates. For very cold climates, panels subjected to heavy wind and snow loads suffered the most. On the other hand, panels in similar climates that were installed in a facade, eliminating the snow load, had very low rates of degradation. At the other extreme, panels in desert climates exhibited large decreases in production over time - close to 1% per year - mainly due to high levels of UV exposure. Panels in more moderate climates such as the northern United States had degradation rates as low as 0.2% per year. Those panels could retain 96% of their production capabilities after 30 years.

      Don't solar panels need to be cleaned of dirt, dust, algae growth? I have to clean my house's siding (and roof if I cared what the roof looks like) of these every couple years.

      You say they last 30 years. Does that mean in thirty years they just stop working or does their efficiency decline slowly or as they near the end, rapidly?

      Or is it like the new florescent light bulbs they say last years longer but half that life they aren't as bright as when new.

      What is it about solar panels that causes them to stop working in 30 years?

      Is solar technology still being improved upon or would you say "it" has arrived and it is not worth waiting for better panels to be developed.
