WORLD ECONOMIC FORUM
Better energy access would help improve the lives of billions of
people all over the world; in the World Energy Outlook 2011 the
International Energy Agency (IEA) estimates that, right now,
there are 1.3 billion people without access to electricity and
another 2.7 billion who rely on wood, coal, charcoal, or animal
waste to cook food and heat their homes, using stoves that are
not only inefficient and damaging to the environment, but also
responsible for two million deaths a year.
These worrying numbers have caused the General Assembly
of the United Nations to declare 2012 ‘the International Year of
Sustainable Energy for All’, calling on business, governments and
civil society to help make access to energy more widespread,
improve efficiency and increase the use of renewable energy
sources.
Energy is ‘fundamental for all, It is the golden thread that
connects economic growth, increased social equity
and preservation of the environment.’ Having energy access
would make a huge difference to the lives of the poorest, and
sustainable electricity even more so; an energy produced and
used as part of longterm social, economic and environmental
development.
With this in mind, General Assembly of the United Nations has
set three targets to be reached by 2030:
•
Universal access to electricity;
•
Doubleenergyefficiency;
•
Double the contribution of renewable energy to
worldwide production.
Access to energy will be one of the central themes discussed
at the United Nations Rio+20 Corporate Sustainability Forum,
which has been organised by Global Compac. The forum will take
place as part of the UN’s Rio+20 Sustainability Development
conference.
Sistemi di energia rinnovabile “Stand-Alone”
With reference to EU estimates, there are more than a billion
people in the world living without electricity. Due to high
investment costs for expanding the public grids and low
power requirements, it would be uneconomical to connect
these remote areas to the utilities in the medium run. Under
these circum-stances stand-alone PV systems present a
logical alternative. According to EU esti-mates, approximately
300,000 farmsteads and buildings in Europe alone are not
connected to the public power grid. In such cases, stand-alone
photovoltaic systems are often the most economic solution.
Stand-alone PV systems are autonomous power grids being
supplied with energy from a photovoltaic generator. Examples
of such systems include electricity supply systems on islands,
for isolated settlements or entire villages. In fact, the optimum
design of an electricity supply system depends primarily on the
following five factors:
1. Required connection power
2. Energy consumption
3. Type of power consumers
4. Period of use
5.Meteorological constraints
Stand-alone power systems are generally differentiated
according to their type of voltage (DC or AC). In DC coupled
systems, the PV generator is connected via a special DC/DC
charge controller.In AC coupled systems, a conventional PV
inverter is used for feeding power into the grid.
DC Coupling
The PV generator as the source of renewable energy is the
crucial component of the stand-alone power system. Other
available generators include those with combustion engines
(e.g., diesel generators or cogeneration plants), as well as
water and wind turbines. The battery or stand-alone power
inverter is the heart of the AC coupled system. It ensures that
generated and load power are balanced at all times.If too much
energy is generated, the inverter stores this surplus energy in
the batteries.
In a DC coupled system, all loads and generators are coupled
exclusively at the battery voltage level (see Fig. 1.1). A DC supply on the basis of a 12-Volt battery is particularly suitable for
simple system con-stellations. Especially when the electricity
is to be used primarily for lighting – such as in a solar home
system (SHS) in the power range of a few hundred Watt. During
daylight hours the battery stores the energy supplied by the PV
generator. This energy is then available in the evening to power
the lighting system. With the help of an additional small inverter,
it is also possible to operate conventional AC power consumers
in the DC system.In general, it is advantageous if AC consumers
can be utilized. These are available worldwide and can be purchased at low cost.
a) System Design
b) AC-DC Systems
Apart from power consumers such as lamps, radios, TVs, and
refrigerators, a stand-alone PV system is made up of four basic
components: a power genera-tor (e.g., PV generator), a storage
battery, a charge controller, and an inverter. These components
can be coupled at various system levels – on the DC side, on the
AC side, or in hybrid systems.
Fig. 1.1
Hybrid AC-DC systems are especially suitable for connecting
mid-range AC power consumers with DC generators. With such
systems, the battery on the DC side can be simultaneously
charged via a combustion unit (see Fig. 1.2). The demands on a
hybrid system differ from those on a solar home system. Hybrid
systems are used to supply remote power consumers and are
able to handle higher
Alongside these technical aspects, there are also cultural,
social, economic, and financial factors which need to be taken
into account.
Solar Home Sysyem
Capable of providing
alternating current
energy requirements. Accordingly, such AC-DC systems are
typically used in farmhous-es, small businesses, and farmsteads. The designer of an AC-DC system should take into account
that the inverter capacity must correspond to the required ener-
gy consumption. Even when more energy is available from PV
and wind sources, he inverter will limit the capacity supplied on
the AC side.

INTRODUCTION EUREKA ENERGY STORAGE
Mankind shall face two great challenges in the
future:
To satisfy the increasing demand for energy To
do the above by using clean energy to protect
environment
So, the investment on solar power as primary
source is the best possible alternative in this time of
changes undoubtedly, considering also the sudden
growth of the world population.
As the supply of fossil fuel is decreasing day after
day, people is directing their attention to solar
power. Sun is the most vital energy source and it
is essential for a greener and cleaner future. Solar
power is the perfect solution to use the most present
resource in nature. By installing solar systems, we
contribute to decrease the greenhouse effect of the
houses, and we can guarantee a better future to the
next generations.
INNOVATION
Powergen’s R&D Dept., leader in the innovative
solutions for battery recharge, developed a compact
solution, resulting from the exploitation of solar
power through efficient solar panels connected to
state-of-the-art sealed lead batteries. You should
not underestimate the use of a sinusoidal inverter
having high quality and resilience standards, inside
the device, which supply energy during the night.
TESTS AND CHECKS
The philosophy of Powergen is to offer a ready to
use product, realized in two boxes, the first one
with an inverter, sensoristics and the control units,
the second one equipped with lead batteries. Both
boxes are realized using strong painted metal
sheet, and are equipped with an access door. Using
an accessible terminal box inside the control box,
you can easily connect it to a solar system already
installed on the distribution equipment, or apply it to
a stand-alone solution.
The system has been tested in radiation conditions
like to the tropical belt: 960W/m2 in full sun
conditions with minimum points of 280 W/m2, with
perturbed sky. According to the simulation tests, by
using medium charges for a home consumption, we
reached a daily average download of the battery of
50%, so sufficient for an average requirement of
7,5KWh/day. (NOTE: SOURCE HIGHFACING).

Energy Storage is an integrated system suitable to
the new systems as well as to the existent ones. It is
easy to install, without changing architecture. It’s a
smart device, which, thanks to the use of batteries,
is able to store the energy produced in excess by
the solar system during the day, and to release it
during the evening in order to save significantly. The
energy exchange with the electrical power network
is unfavorable in comparison to personal use,
because the value of the energy input is lower than
the value of the electricity withdrawn.
Moreover, Energy Storage can work using a UPS in
the event of black-out. Please, find a small overview

From an economic perspective, today stand-alone power systems with a storage battery are considerably
more cost-effective in the kW power range than systems which use diesel generators only. Due to the
longer service life and lower maintenance costs of the units, even larger hybrid systems which use a diesel
generator solely to avoid long-term battery storage can be operated at lower costs than stations working
exclusively with diesel units. In particular, any evaluation of the costs arising must make provision for the
fact that in remote regions one kilowatt hour can easily cost between 0.50 and 1.50 Euro.The investment
costs for expanding a grid depend primarily on the length of the grid expansion. In the case of hybrid
systems the investment costs depend on the types of loads to be supplied. The required size of the PV
plant is derived from these factors. The cost-effectiveness of PV hybrid systems compared to pure diesel
systems is clearly demonstrated if an examination of the costs is carried out over the service life of the
two systems.
PV hybrid systems can be operated economically on a long-term basis. In view of the rising cost of energy
and raw materials, hybrid systems running on renewable energy sources present a real alternative and will
open up new areas of application.
