Home Solar Power

The Beatles rejoiced at the sight of the sun and sang, ‘Here comes the sun”. Indeed, the sun has been spreading joy and warmth all over the world since time immemorial. The best thing about the sun is that it is free to enjoy. Irrespective of religion and nationality, the sun shines upon all of us in all its glory. And now, man has the knowledge and know-how of harnessing a part of the tremendous energy contained in the sun and putting it to various uses.

The most common way of using the energy of the sun is with the help of photovoltaic cells. Even though the initial set up costs can be a little high by most standards, the long -term financial benefits of using home solar power are truly unparalleled.

The sun provides us with a unique advantage of generating enough power for ourselves and sell off any surplus to the local utility company or the grid at a profit through what is known as the “Net-metering Scheme”. It requires no raw materials and has no running cost. All one needs to do is connect the system to the local power grid and send back the excess power generated by him to the local company. An example will make things clearer. Say, your monthly electricity consumption is X number of units or A amount of dollars. Now, if you install a solar panel at your home that can produce 6X number of units per month that is equivalent to $5A and you draw 2X number of units from the utility for night time consumption, you are still left with 6X minus 3X or 3X number of units equivalent to $5A minus $A or $4A in your hand. Selling off surplus power seems like the only sensible and smart choice because you cannot store this power for use on rainy days. If left unused, it will go to waste. So why let that happen? The best move is to sell it back and make a neat little profit from it.

One of the most important considerations when you are thinking of setting up your very own home solar power system is the return on investment. Be warned that the initial investment can be fairly high by most standards, even though most states will extend financial assistance to you for the cause. This is because solar energy is eco-friendly and a clean renewable form of energy does not pollute the environment. However, you can always find out the break-even point by subtracting the value of the annual sale of electricity from the initial investment made by you. Take a look below for a typical example.

Initial investment $30,000 Annual sale value of solar electricity $ 5,000 Number of years to reach break-even point 6years From the 7th year onward everything is free

The ecological benefits of using solar energy are too strong to deny. In fact, one of the biggest advantages of using solar energy comes from its clean, renewable, non-fossil fuel oriented and sustainable nature. Solar energy production does not cause air pollution because, unlike other conventional modes of energy production, there is no discharge of sulfur dioxide (SO), carbon dioxide (CO), nitrogen oxide (NO) or mercury. And for the same reason, solar energy does not contribute to the contemporary problem of global warming or greenhouse effect. What’s more, with solar energy you never need to worry about smog or acid rain in the area where it is utilized. What could be ‘greener’ than this?

One more advantage of using solar energy is due to the fact that it is virtually free and requires very little maintenance. Once set up, there are practically no recurring costs.

Solar power setups are self-sustained and an independent means of energy production. This distinctiveness of operation helps installation of units anywhere under the sun, irrespective of whether other facilities are available or not. In other words, it may be said that solar energy really sets you free. Nowadays, owing to the latest developments, it doesn’t take much to set up a fully functional home solar power unit near your own house and start generating your own electricity. Moreover, home solar power offers excellent portability. Powerful Solar energy units mounted on trailers, complete with control panel, converters, battery banks and switches are now in use in such remote areas like the South African Game Reserves where scientists are busy checking the genes of large animals like the rhinoceros or the giraffe. Independent solar energy operated units help light up their camp sites while powering their laptops for research work and other equipment and tools.

There is a general concern all around the globe over our dwindling natural reserves of fossil fuels. Solar power has effectively reduced the dependence on Middle Eastern countries whose oil supplies had so far been responsible for fossil fuel generated electric power. In fact, considering the pace at which mankind is adopting home solar power in homes and workplaces, the day is not too far away when diesel and petrol powered generators would become extinct.

All said and done, let us now take a look at some of the disadvantages that accompany solar energy uses. A disturbing factor is the present high cost of installation of a solar panel. Though efforts are underway to improve their affordability (there are many government schemes that extend financial help to those willing to install a home solar power unit), the picture is still far from encouraging.

So are you ready to opt for solar energy - there are simply too many advantages to ignore it. What you need is a training guide - a manual, that will let you learn how to install a system. You will also need to know a few other things such as what is the best place to set up the system, where to buy the parts, how to get free batteries, safety precautions and also wiring the system. Get informed and you are ready to install solar system in your home.
