Roof Solar System
In a standard solar power plant; On average, 700 – 800 VDC (open circuit) voltage value produced by 20 series-connected photovoltaic panels in each panel array is transferred to the inverters and transferred to the transformer kiosk as 380 – 460 VAC (Nikola Tesla – 1888) at the inverter output. In the transformer kiosk, this voltage value is associated with the hermetic type transformer (transformer) through the low voltage protection / measuring elements. If the medium voltage (MV) value of 36 kV (36,000 V) is at the transformer output, energy flow is provided to the interconnected system after the disconnector / measurement / breaker MV cells.
Roof type solar power plants also work in this way and additionally, if preferred, energy can be stored on accumulators. If the production steps are to be listed;
1) Manufacturing the load-bearing construction on the roof and associating it with the existing construction
2) Installation of photovoltaic panels on the construction
3) DC cabling from the roof to the ground and manufacturing of the collection panel
4) Installing inverters in a suitable location on the ground
4a) Optional manufacturing of battery groups in an environment isolated from atmospheric conditions
5) Bidirectional meter and transformer installation for interconnected (on grid / mains connected) type systems
5a) Distribution panel manufacturing for closed circuit systems (off grid).
*** In residential solar power plants; Since the panel area is low, it is recommended to store energy on the accumulators. Considering the limited installation space (the amount of panels that can be installed) and the investment costs, it is inefficient to meet the required energy directly from the panels. For this reason, energy should be stored on the accumulators and energy should be provided during periods of low or no radiation (evening / night).
