The owner of a Greek gift’s shop decided to install solar panels on the tile roof and terminate his contract with the national energy supplier (Δ.Ε.Η).  The south-east facing roof  is not fitted with 3000Watt of photovoltaic panels. The solar energy is fed directly to the electrical loads (air condition, led lights, a small fridge, computer, outdoor lights and LED Signage) and any excessive power is stored to the AGM (Lead acid) batteries. The back up energy is used at night or in cloudy days. The solar kit for off grid power supply is described below.

The inverter is connected to a solar arrange with 12 solar panels, the combiner boxes contains all the necessary protection such as string fuses. The single DC Ouput IS around 100-110vDC with 32Amps. The total power is 12x 250W that is 3000Watt. The annual energy yiled of the off grid system will be over 4,110kWh.

The customer provided a customized mounting system with two levels of racks, due to space restrictions, a special support rack was necessary that respect the mounting regulations of Hoppecke. The maximum distance between the batter blocs and maximum cable length was taken into consideration. The overall capacity at C10 charge rate is 8kWh.

This is the back side of the shop. There are 9 solar panels from EGING with power rating 250Watt each.
The panels are available here at very competitive prices only £120 for a brand new photovoltaic module.

Fact : Solar panels under full sun. 10-15kWh per day from 2250Watt of installed solar energy
