Solar power operates by capturing the sun’s energy and turning it into electricity for business or your home.

The sun is a nuclear reactor. Each hour, enough photons affect our planet to generate power that is enough to meet global energy needs for an entire year.

Currently power accounts for of 1 percent of the energy. But technology is advancing and the expense of going solar is falling so our ability to harness the abundance of energy of the sun is rising.

A 2017 report by the International Energy Agency reveals that solar has been the world’s fastest-growing supply of electricity — marking the first time that the growth of energy has surpassed that of the other fuels. In one way or another, we will enjoy the benefits of power in the coming years.

When photons hit on a cell, they knock electrons loose from their atoms. It creates an electrical circuit if conductors are attached to the sides of a cell. Power is generated by them, when electrons flow through a circuit.

Photovoltaic (PV) solar panels comprise of many solar cells. Solar cells are made from silicon. They’re built with a layer exactly like in a battery.

This case shows a battery. The electrons return to the side of the battery, and move through the lamp, from the side of the battery.

With AC (alternating current) power, electrons are pulled and pushed, occasionally reversing direction, similar to the cylinder of an automobile’s engine. When a coil of wire is spun near a magnet AC power is created by generators.

AC power was selected for the U.S. electric power grid, primarily because it is less costly to transmit over long distances. But, DC electricity is created by solar panels. How can we put DC power? An inverter is used by us.

A inverter takes the DC power and uses this to make AC electricity. Inverters are similar to the system’s brains. Together with inverting DC to AC power, they provide ground fault protection and system stats, including current and voltage on DC and AC circuits, energy generation and power point tracking.

The industry has been dominated by central inverters . The introduction of micro-inverters is among the technology changes in the PV market. As inverters do micro-inverters optimize for an entire system, not for every individual panel. This allows each panel. When a central inverter is used, having a problem on a single solar panel (maybe it is in the colour or has gotten filthy ) can drag down the performance of the whole solar array. Micro-inverters, like the ones in the Equinox house of SunPower system, make this a non-issue. The remainder of the array performs efficiently, if one panel comes with a problem.

Here’s a good example of a house energy installation functions. Sunlight strikes on a panel on the roof. The panels convert. The inverter converts the power from DC. It clean and simple, and it is becoming affordable and more efficient all the time.

Every day, what happens if you are not to use the electricity that your solar panels are creating? As soon as your system isn’t generating energy in time, and what happens at night? Do not worry, you still gain through a system known as “net metering.”
