Solar Enegry

Every hour, enough photons impact our planet to theoretically satisfy global energy needs for an entire year. Solar technology is improving and costs are dropping rapidly, though, so our ability to harness the sun’s abundance of energy is on the rise. In fact, a report from the International Energy Agency indicates that solar energy could become the largest global source of electricity by 2050. In the coming years, we will all be enjoying the benefits of solar-generated electricity in one way or another.

When sunlight hits solar cells, electrons are shaken free and move around. Electrons are the negatively charged particles that sit around the nucleus of an atom (the nucleus consists of protons and neutrons). An electric current is simply the movement or flow of electrons in the same direction. A bolt of lightning, for example, is a sudden surge of electrons across a build-up of charge within clouds, or between clouds and the ground.

If you place a group of these PV cells together in a panel, and install a number of panels side by side, you can create a flow of electrons and DC electricity. The electricity used in households, however, is AC 240 volts. Therefore a box called a solar inverter - usually no bigger than your average shopping basket - is used to convert the DC electricity to AC so it can be used immediately by occupants and the electricity grid.

The above PV electricity system is categorized as follows

Solar Grid System

In sri lanka under the team battle Solar energy introduced by Sri Lanka sustability authority that connect this solar grid connected system is categorized in to following three concepts.

Net Metering

1. Pay your domestic electricity bill using the solar energy units that you generate.

2. Additional energy units will be deducted from your electricity bills for the next ten years

3. No monetary payments will be made.

Net Accounting

1. Pay your domestic electricity bill using the solar energy units that you generate

2. Get paid for each additional solar unit generated.

Net Plus

1. Pay your electricity bill seperately and earn money for the energy units that you generate.

Solar stand - alone System

In sri lanka under the team battle Solar energy introduced by Sri Lanka sustability authority that connect this solar grid connected system is categorized in to following three concepts.

Stand-Alone System -Since there is no battery to store electrical energy, energy is used immediately. Common applications are direct power to DC loads, water pumping and telecommunications. With an inverter it can also power AC loads. This system only works when it's sunny.

Stand-Alone System with battery backup - can supply power 100% of the time: At night, on cloudy days and when the utility power is down. Excellent for remote applications where utility grid is inaccessible; cabins, boats, RVs and for emergency backup systems.

Typical PV System Components

Solar Module

The solar array consists of PV modules which convert sunlight into electric energy.

Stand-Alone PV systems are designed to operate independent from the electric utility grid, and are generally designed and sized to supply certain DC and/or AC electrical loads. Stand-alone systems may be powered by a PV array only or may use utility power as a backup power source.

Inverter

Besides providing miscellaneous solar power solutions for private clients and residential buildings, we also help commercial businesses, as well as government institutions in switching to solar power.
