Q1. What is a photovoltaic (PV) system ?

PV stands for "Photovoltaic", PV systems use photovoltaic cells to convert sunlight into electricity.
Originally developed to power spacecraft and satellites, the cells are made from silicon, these cells are normally wired together on a panel.
A group of these panels is called a PV Array.

Additionally to the PV cells in a complete PV system there are other components like batteries, controllers etc.

Q2. Must the photovoltaic system be mounted on a roof ?

No, absolutely not!
While mounting it on a roof is optimal you can also mount it elsewhere as long
as there's enough sunshine.

Q3. How long does a photovoltaic system last ?

Solar panels come with a warranty of 25 years !
The inverter can have a warranty of up to 10 years.

Q4. How fragile are the panels ?

Panels are normally made of strong tempered glass, they have to pass standard test
and are able to deal with all kinds of weather situations.

Q5. What about snow ?

Solar panels must not be covered by anything, while it is possible that
a panel still generates electricity while it is covered with snow it is recommended to clean them.

Q6. How long does the installation take ?

This depends on the size and complexity of your desired installation but for
most installations it takes 2 - 5 days.

Q7. What is Maximum Power Point Tracking (MPPT) ?

Solar inverters use maximum power point tracking to get the most out of your solar panels. As every single
module of your solar panel has its own maximum power point, the inverter has to take care on what amount of power
it draws of each module.

Q8. What is Anit-Islanding protection ?

If grid tied inverters do not detect the presence of a utility grid, they normally shut off. As in all electrical systems
the circuits sometimes resonate at the frequency of the utility grid, inverters without anti-islanding protection may
think the grid is still present and may therefore not shut off as usual.
