Planning

As with a vast majority of renewable solutions, energy storage remains the largest hurdle to overcome in our goal of replacing fossil fuels as a source of energy. Renewable Solutions such as Wind and Solar power depend solely on the presence of wind and sunshine to produce electricity; both of which are not always available when we need power. On small scale applications (home or office), the most economical solution today remains battery storage – the problem being that battery technology is severely lagging the pace of technology.

On-grid or grid connected solar pv systems utilize the existing electrical grid as a means of storage. During the daylight hours a solar pv system is generating electricity and distributing it onto the grid for use by anyone who is connected to it and at night, when the solar pv system is not generating electricity, you are obtaining power from the grid. During the day you are selling power to the Utility and at night you are buying power back from the Utility, with the end goal being power sold= power bought.

There are 4 major components in a grid connected system:
(1) a Solar PV array,
(2) Inverter,
(3) Main Electrical Panel, and
(4) Bi-Directional Meter Solar PV Array: converts the suns energy in DC electricity Inverter: converts the DC electricity into AC electricity Distribution Panel: a point of AC electricity distribution Bi-Directional Meter: a means for the utility to track the power being sold to the grid vs purchased from the grid.
