PV systems, Electrical lighting distribution: what are pro's and con's of a low voltage DC network vs 230VAC netwerk
I am involved in PV projects, mostly electrification of schools, medical centers etc; I used to work with low voltage DC distribution but with the availability of more powerful PV panels rating 24VDC, I presume that it is preferable to go for a 230VAC system, also for lighting purposes.
Typical cases I am working on are e.g. the lighting (for evening courses) of two classrooms, each 8mx4m, together with lighting for the manager’s office (4mx4m) as well as exterior lighting. On another occasion I look into the lighting of a medical centre, encompassing several rooms in one building with a total ground surface of approx. 12mx6m.
What I want to know is if there is any preference, eventually depending on local circumstances, to be given to a 12VDC or a 230VAC distribution for only lighting.
This relates to a number of countries (as a member of Engineers without Borders/Belgium) that are interested in energy and water supply with current projects in countries including Togo, Cameroon, Mali, Burkina Faso, Uganda, and India.
