Planning an Off Grid system
Given the basic requirements, while planning any type of Solar PV System, the off-grid system differs in design in regard to certain additional components.
- Dry and ventilated storage place for batteries, if possible protect against low temp (optimal around 20°C)
- Thermal systems
- Additional roof statics approx 50kg for 1 installed collector (40kg collector, 10kg mounting system).
For 2 collectors 100kg,
for 3 collectors 150kg etc.
- Plan an additional area, approx 1x1m for solar heater in boiler room and its integration with the conventional heating system.
- Optimally angle for thermal systems is 40-45° and results from a focus on energy yields in autumn-spring period. In summer almost every thermal system produces unused excess of energy and in this period optimal system-inclination is secondary. An exception is industrial thermal systems or pool connected, where an excess of energy does not occur, in this cases system-inclination is 30°
