Grid tied for customers with a high kWh demand in day time. A grid tied inverter will reduce your current electricity bill by up to 50 – 80% when the sun is shining during day time and load conditions. This is a long term investment as equipment used are designed to last 25 years, with exceptional return on investment. Normally these systems pays itself off in 3 – 5 years, depending on electricity unit pricing. They are also installed with a complete monitoring system and a meter not to feed back into the grid, and this depends on your utility grid provider. Inverters and PV panels can be added as customer’s electricity production increases.
