We are living in exceptional times. Scientists tell us that we have 10 years to change the way we live, avert the depletion of natural resources and the catastrophic evolution of the Earth's climate. The stakes are high for us and our children. Everyone should take part in the effort, and HOME has been conceived to take a message of mobilization out to every human being. For this purpose, HOME needs to be free. A patron, the PPR Group, made this possible. EuropaCorp, the distributor, also pledged not to make any profit because Home is a non-profit film. HOME has been made for you : share it! And act for the planet.

Progress in Photovoltaics: Research and Applications - Wiley Online Library
Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available renewable energy on earth. Only a minuscule fraction of the available solar energy is used.
Solar powered electrical generation relies on heat engines and photovoltaics. Solar energy's uses are limited only by human ingenuity. To harvest the solar energy, the most common way is to use solar panels.
Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.(wikipedia)
This journal is a major forum for reporting advances in this rapidly developing technology - from research to practical application - and provides leading edge coverage for professionals, researchers, and solar energy policy-makers in this important field. This journal published online via Wiley Online Library.

Testimonials
"Hi, My name is Tomas and I have spent a great part of my life working for
power plants and electricity companies. I am now retired and I no
longer fear to share what I have learned over the years. Power companies
are charging you way too much for electricity! They have been using the
recent fuel problems to justify their price increases, but this just
isn't fair to people like you and I. You know why? Because power production costs are way under what people believe them
to be!Power companies are charging ridiculously high costs for their
electricity because they know that no matter how much they ask you to pay for it,
you will HAVE to pay it. Who can live without electricity, right?"
"Well,I had built a mini solar system to generate enough
solar energy to power my light bulb to test it out and it worked out
fine. So one can go ahead to build a big one and save up to 80% of the
electricity bill. The results vary from person to person, because
everyone uses a different amount of fuel or consumption of electricity
at their home. Energy prices
in the global world are rising up and we need such alternate energy to
generate savings which will secure for the future, like solar energy"
"Hello.A few years ago, I started looking into solar energy. Just like you,
I started with an online search exploring on how I could save money
with photovoltaic electricity.However, I didn't know of the rising progress in photovoltaics and ignorant as I was, I was shocked to see how much it cost to
have solar panels installed at my house! The estimate I received was
over $35,000 and the payback time for that was just way too long. I certainly didn’t have that kind of money, not even close. I was resigned to the idea of paying the electric company each and
every month until I met a friend who had a solution. My friend explained
that he was building his own photovoltaic panels for just a fraction of the cost of new retail solar panels. And he wasn’t alone. The only things he needed was patience and a HOW TO MAKE SOLAR PANEL guide"
"Hi. Windmills and solar panels are being sold at prices averaging $3000.Most people believe the only way to get solar energy and wind power is to buy factory-built solar panels and windmills and that it is too costly to be envisageable by average-class people. WRONG! I prefer the OTHER way most people don't know about. The CHEAP way. I simply built my own photovoltaic cells"

The advantages and disadvantages of Solar Energy and Photovoltaic Cells
Advantages
- Fuel source without limit
- Free main source is the sun
- Environment friendly, clean, do not contribute to global warming, acid rains or smog, helps the decrease of harmful green houses gas emissions
- You can use it for different purposes: vehicles running on solar power
- Renewable
- Give us a way to harness power in remote locations
- The development of new technologies allows us to store the collected solar power through solar power battery chargers.
- Cheaper than electricity heating
- It is produced where it is consumed
- Does not use fuel therefore does not contribute to the cost of the recovery and transportation of fuel or radioactive waste
- Become an official green business through Green Business Programs
- Solar power production is a silent process
- The equipment needs little maintenance
- Saving money on long term basis
- The equipment is easy to install, so why don't you try it yourself?
Disadvantages
- Diffuse source – you need large number of solar panels to produce the needed electricity, from there you need a large land spot for this purpose
- There are locations in the world where this energy is collected efficiently. But some of the locations are not with the appropriate sunlight.
- The initial cost of the solar panels are expensive investment,so it's better to save money of hand labor and build it alone
- You can collect it only during the day
- Depends on the climate conditions
FAQs
1. Which is better, to build it myself or hire someone else?
1. Which is better, to build it myself or hire someone else?
Answer: In order to decide that, you have to
consider your financial status. Many
homeowners cannot have solar panels because the installation fee is expensive.
Why hire for constructors when you can do the job yourself? Better look for steps
in constructing the solar energy power
source for home use now if you want to have one too. In both cases you
save money for not paying electric bills.
2. Can I claim a fit from the electric company if I produce more energy with my photovoltaic cells than I need?
2. Can I claim a fit from the electric company if I produce more energy with my photovoltaic cells than I need?
Answer: Yes, but only if you hire a solar
constructor to install your pv system, still if you build alone you save money.
3. What is the rated life span of
a good solar panel?
Answer: They are warranted for 25 years, but 40
years is probably closer to their lifetime. To make them help maintain their
efficiency, make sure you clean them at least 3-4 times a year, or more in
dusty conditions, and if you install a cooling system, probably they last longer.
4. If you use solar panel roofs during the
day, what happens at night?
Answer: Nothing, no
electricity is generated. Also on rainy days, nothing. You need direct sunlight
for them to work. That is why solar-powered systems need batteries to
store the power the panels produce during the day. This method is quite costly
as the batteries are expensive and must be replaced after a bunch of years.
There is also another way. Most solar energy systems today don't have battery
systems, they just send excess energy back into the grid and your meter rolls
backwards. So, you can use the panels during the day and use the grid at night
while still having an energy bill near or maybe below 0
5. How much does it cost a solar panel?
Answer: That would depends on the size and power output.Here you can find in Amazon.com the cost for photovoltaic panels
