1) What is the best angle for solar panels?
The optimal angle for placing solar panels is 50° for systems in
Nordic countries and 20° for South-European countries.
2) How much power will I lose if panels are incorrectly
placed?
A system set at an angle of between 20 and 50° facing south will
produce around 5% less power per year. When panels are
installed at an angle of 35° and the system is oriented between
south east and south west, the energy shortfall on an annual basis
will again be around 5%.
3) How does heat affect my system?
The output of a system is reduced when panels become warmer.
The power shortfall can be 0.3 to 0.5% per °C.
4) What is the life span of a solar panel?
With proper maintenance, the modules should last at least 30
years.
5) How long do inverters last?
You should expect an inverter to function for at least ten years.
The actual figures depend on the location of the inverter (the
hotter the temperature, the shorter the life span) and whether
or not regular maintenance is carried out. A humid environment
will affect the life span as well. The ideal place to install an in-
verter is always in a dry and preferably conditioned environment.
6) Is it possible to remotely collect system data?
There are various options for accessing inverter data. See this
brochure for more information or ask your supplier for advice.
7) Do the panels have to be kept clean?
The modules are in principle maintenance free and the panels are
washed clean by rain. It is worth considering cleaning the panels
with water once every year.
8) What happens if the grid breaks down?
The solar energy unit will stop returning power to the grid. This
is necessary to ensure the safety of the system at times when
maintenance is being carried out or there is a failure on the grid.
Please consult your supplier if you wish to keep receiving a 230
Volt current when the grid shuts down. Mastervolt has various
handy options for providing emergency power.
9) Do the panels also provide electricity doing cloudy
weather?
The panels continue to produce energy even when it is cloudy,
albeit on a smaller scale.
10) Can I connect equipment directly to the panels?
Equipment cannot be connected directly to a grid connected
solar installation - an electricity grid is always necessary.
AC consumers can be directly connected to grid independent
sine wave inverters in island systems.
11) Is there any difference in the electricity coming from a
solar system?
No, the current is the same.
12) Can my solar installation attract lightning?
There is no record of this ever occurring. The chance of lightning
striking is equal regardless of whether or not you have a solar
system.
13) Can a solar installation cause damage to my household
equipment?
No, this is not possible. The inverter functions as a sort of filter
between the grid and the PV system and complies with the
highest suppression standards.
14) What happens to the electricity that has been
generated but not used?
The electricity generated by the solar panels is first consumed by
the various equipment in the building concerned. Any excess
power produced is returned to the public grid. Make sure you
request from your energy supplier a meter that turns backwards
if one is not already installed.

15 kW p s y stem in s t alled i n G r eece
This system was installed at the end of 2003 by a local Greek company on a
building near Athens. A total of 200 75 Wp Astropower solar panels supply 15
kWp of power for local consumption and returning to the grid. Six Sunmaster
QS3200 inverters are placed between the solar panels and the grid. This is a
powerful system that meets the required energy needs virtually autonomously.
