A photovoltaic installation is one of the most cost-effective solutions with a positive impact on the environment. In the long term, it will allow you to make significant savings on your bills and to become independent of external electricity suppliers. Before buying panels, however, opt for a specialised audit. What does it involve?
There are many advantages to installing a photovoltaic system, but in order to enjoy them, the individual components of the photovoltaic system need to be correctly selected and then properly installed. This will ensure that photovoltaics will be a good, future-proof investment. What exactly is a photovoltaic audit and why is it worth performing one?
What does the efficiency of a photovoltaic installation depend on?
Photovoltaics work by taking the sun’s energy and converting it into electricity, which can then power all the appliances in the household. For this to happen, the photovoltaic panels must receive the maximum amount of sunlight possible. This in turn is influenced by their correct positioning. The most favourable solution is to position them towards the south at an angle of 30-40 degrees. In addition photovoltaic systems must not be obscured by tall trees or buildings
The material from which the individual modules are made, the structure of the modules and the technology used also affect the efficiency of photovoltaics. Before buying an installation, it is also important to find out how much power will be required to meet the needs of the household
What is a photovoltaic audit?
A photovoltaic audit enables the photovoltaic installation to be selected in the most favourable way for the prosumer. It consists of several stages, the first of which is an analysis of the electricity bills and a discussion with the investor about expectations. This is followed by an assessment of the installation options, in particular
- the shape, surface and angle of the roof;
- the presence of skylights, chimneys, and caves;
- the orientation of the roof slope in relation to the world;
- type of roof covering;
- the presence of nearby tall trees and buildings (shading analysis).
This is also the point at which a decision can be made on the type of photovoltaic installation – roof or ground-mounted. The photovoltaic audit concludes with an in-depth analysis of future expenses. You will find out what prices on your bills you can expect (including increases) and in how many years your investment is expected to be paid back
Photovoltaic audit – why is it worth it?
With a properly conducted audit, you will find out which type of photovoltaic system will be the most beneficial in your case and what power to choose to meet your household needs. You will also be informed about the routing of cabling and installation details. You will learn about the cost of purchasing, installing and maintaining photovoltaics.
Every home is different and has different requirements – so the installation should be selected individually. A photovoltaic audit is carried out by an experienced and trained renewable energy specialist
