Solar Panel System
Grid Tie System
Grid-tie system is a solar powered system that is hooked into the local utility grid.
Example 1.5 kW system
The 1.5 KW is a total DC rating of the PV solar panels or PV solar modules. This will be derated by a conversion factor of approximately between 0.7 and 0.8 to become usable AC rating.
Let us say, 0.7 multiplied by 1.5 kW = 1.05 kW
Example of loads in Jollibee:
Lights, LED, 15 nos. of 20 watts = 300 watts
Electronic Cash Register, 200 watts
Hand Dryer, 150 watts
Blender, 2 nos. 200 watts = 400 watts
Total = 1050 watts or 1.05 kW
Looking at the picture, there are two sources of power, the utility grid (MERALCO) and the PV solar system which is an alternative power generation.
The arrow indicates the flow of energy supplying the loads (represented by the bulb). The inverter which is an intelligent device enables the PV solar system to be the first priority to supply the energy to the loads. If the energy is insufficient, the deficit will be sourced from the utility grid (MERALCO grid).
During the peak sun-hours (mid-day), the energy coming from the sun must be fully utilized.
Otherwise, let us say, the loads are less than 1.05 kW or 600 Watts to be exact, the remaining 450 watts produced by the PV solar panels will just go to the utility (MERALCO).
As of now, net metering is still an issue where the excess energy will be paid by the utility grid.
Budgetary System Price List
Off Grid System
Off Grid System is a solar powered system that is independent to the local utility grid and also called as stand alone system. This system use batteries for storage.
Wind Turbine System
Wind Turbine converts energy created by the force of the wind into electricity, which can be stored in batteries.
Prices are indicative and subject to price change due to conversion rate.
Final installation cost would be defined based on the actual layout of the system
