Product Description

Renewable Energy Solar Array System for a Grid-tie Network

With this formula, you can calculate the number of Solar Panels that would be required to be installed at your location in conjunction with the Grid to satisfy your desired power(W) needs for both cold and hot climates.

We provide you with this comprehensive "Array sizing calculator" to determine the number of panels required to satisfy your power (W) needs.

A 'How to Calculate Voltage Drop' formula between components is also provided. Watch product video. 

Included inside also, is a Wire Sizing System Worksheet.

Recommended below: (kW - kilowatts)
1.  Off-grid/stand alone - 7kW and over /day or just want to be independent by producing one's own energy
2.  Battery design) - for back up purposes
3.  Gridtie - 5kW and above/day
4.  Grid tie /w battery backup - 5kW and above/day

For consumption below 5kW/day, choice left up to consumer to decide whether grid tie or stand alone
NB: grid tie is sharing electricity consumption with the power company and a battery backup can be incorporated for loads/appliances that should be always on.
