Rising electricity costs hamper your
Germany is a good example of rising
energy costs: since 2006, the price of
electricity has risen by an average of
4.8 % p.a., and the current situation is
likely to get worse in the future. Experts
anticipate annual electricity
price increases of up to 5 %. The resulting
additional costs pose a real
economical challenge, particularly to
medium-sized enterprises .
As well as financial pressure, the continuous
price increases also represent a
critical planning uncertainty for your
business. For commercial businesses it
is therefore a good idea to obtain as little
electricity as possible from the public
power grid and focus instead on selfgenerated
electricity for self-consumption.
This ensures you have a long-term
stable and cost-effective electricity
price and will become more independent
from your public energy supplier.
Electricity prices are currently at
15–19 euro cents* per kilowatt hour for
medium-sized enterprises. Unlike in
large companies and electricity intensive
businesses, as a German mediumsized
enterprise you do not have the opportunity

Photovoltaics guarantees you stable
and low electricity prices
With a photovoltaic system from
IBC SOLAR, you can easily produce
the electricity you need for your company
yourself – at a fixed price. Selfconsumption
is therefore an economically
attractive alternative to conventionally
generated electricity from
your energy supplier.
What actually is self-consumption?
We talk about self-consumption when
self-generated electricity is consumed
immediately and directly at the site
where it is produced. The specific selfconsumption
rate depends on the individual
load profile – how much a company
consumes – up to 100 % is possible.
Electricity cost security for at least
Photovoltaics is an investment that pays
off. The prices of components have fallen
sharply in recent years, meaning that
investment costs have become considerably
lower. However, the key savings
potential lies in the favourable and
steady electricity production costs over
the years to come. Secure yourself low
electricity costs for the next 20 years
with an investment in a photovoltaic system.
One kilowatt hour (kWh) of self-produced
solar power currently costs on
average 10 euro cents. The level of electricity
procurement costs means that it
is worth generating and consuming your
own electricity with a photovoltaic system.
GOOD TO KNOW:
Electricity at a reasonable fixed
price and attractive system

of solar energy a sustainable,
Installing a photovoltaic system on a flat roof
Using your own solar power is ideal for
For the majority of medium-sized enterprises, solar power self-consumption is ideal
because a photovoltaic system produces the most electricity during core working
hours – exactly when it is needed.

E.g. commercial business: production only on weekdays

E.g. commercial business: continuous production
Thanks to the coverage of the power production curve and load profile, companies
in the commercial sector can often use the majority of their self-generated electricity
on site. Production machines, air conditioning units, emergency lighting and electronic
data processing run round the clock so there is always demand for electricity.
Particularly high self-consumption rates are reached by companies with continuous
production, whose electricity consumption rises in the morning, peaks at midday
and drops again in the evening or is on the whole considerably higher than the solar
GOOD TO KNOW:
Every industry has a characteristic
load profile which we can use
to accurately predict the selfconsumption

Profit from your previously unused
Overview of the benefits you will see with commercial self-consumption:
A Reduced electricity bills
Thanks to self-consumption, you will
need to buy less expensive additional
electricity from your supplier. You can
therefore relieve the financial burden
on your company in the long term
and increase competitiveness.
A Exploit potential
Convert your unused roof areas
into production sites. As well as cost
savings for self-generated electricity,
in many countries a fixed remuneration
for the unused electricity

A Fixed electricity price
You produce your own electricity at
a long-term fixed price. The less you
need to buy additionally, the more independent
you are from your energy
supplier, keeping your power supply

Example of beneficial forecast*
The annual consumption of the business in the following example is 1100 MWh.
The current purchase costs for electricity from the public grid are 17 euro cents per
With self-generated electricity the costs per kWh drop by 7 euro cents to 10 euro
cents per kWh. This was calculated with a system of 500 kWp and a self-consumption
rate of 70 %. The remaining 30 % of the electricity generated can be fed into
the public grid and will be remunerated in many countries.
The total saving after 20 years with no electricity price increase is EUR 647,500,
or with an electricity price increase of 3 % it is EUR 1,036,500.
