I am building my house. When should I anticipate the installation of a PV system?

The sooner you make the installation forecast Φ / Β system, the better. It is good that the photovoltaic system that you will install has been included in the design of the house from the beginning. A comprehensive study covering energy savings (insulation, windows, shading, etc.), heating and air conditioning and electricity needs will help you achieve the best result at the lowest cost.

The position of the photovoltaics is very important for their efficiency. If you are building your home now you can configure your roof to accommodate photovoltaic panels. This will save space from the garden or the yard, as well as part of the support costs of the frames, while optimizing the position of the frames to make the most of the sunshine.

Is the building I have suitable to receive photovoltaics?

Most buildings are suitable. As long as the following conditions are met:

1.    There should be sufficient free and shade-free space. As a rule of thumb, calculate that you need about 0,8 square meters for every 100 Wto (if you use the usual crystalline photovoltaics of the trade). If you install amorphous photovoltaics again, the total cost will be about the same or even lower, but will require 2-2,5 times larger surface area. Take special care that the space is as 100% shaded as possible ?? throughout the day. Otherwise, your system will run at a lower efficiency.

2.    Photovoltaics have the maximum efficiency when they are south oriented. Deviations from the South up to 45o are permissible, but reduce the yield.

3. Η correct inclination of the photovoltaic in relation to the horizontal plane. An inclination that gives the best results throughout the year is almost always chosen. A general rule is that the optimal slope is equal to the geographical parallel of the place. Of course, each rule has its exceptions, in areas with humid climates, where due to water droplets in the atmosphere much of the solar radiation is diffused in the sky, the optimal inclination of the solar collector for the whole year is about 10-15 % less than the local latitude angle.

4.    Yes emake sure you have the right space for electronic systems and batteries (if you choose the standalone system)

5. Keep in mind that together with the bases, a complete photovoltaic system weighs about 15-20 kg per square meter.
