Zensoft's Solar System

For billions of years, the sun has poured out huge amounts of energy in several forms, including light, heat, radio waves, and even x-rays. The Earth, in orbit around the sun, intercepts a very small part of the sun’s immense output. On Earth, direct sunlight is available from sunrise until sunset, except during solar eclipses. ZENSOFT’s solar systems and modules are designed to capture the sun’s energy and change it from radiation into more usable forms such as heat or electricity. In fact, sunlight is an excellent source of heat and electricity, the two most important forms of energy we consume.

Visible light can be converted directly to electricity by a space-age technology called a photovoltaic cell, also called a solar cell. Most photovoltaic cells are made from a crystalline substance called silicon, one of the Earth's most common materials. Solar cells are typically made by slicing a large crystal of silicon into thin wafers and putting two separate wafers with different electrical properties together, along with wires to enable electrons to travel between layers. When sunlight strikes the solar cell, electrons naturally travel from one layer to the other through the wire because of the different properties of the two silicon wafers.

A single cell can produce only very tiny amounts of electricity-barely enough to light up a small light bulb or power a calculator. Nonetheless, single photovoltaic cells are used in many small electronic appliances such as watches and calculators.

To capture and convert more energy from the sun, photovoltaic cells are linked to form photovoltaic arrays. An array is simply a large number of single cells connected by wires. Linked together in an array, solar cells can produce enough electricity to do some serious work! Many buildings generate most of their electrical needs from solar photovoltaic arrays, example like our customers in Putrajaya, which gets 70% of its power from the sun.  

ZENSOFT solar systems can be applied like roadsides, on farms, and in the city, wherever portable electricity is needed. They are commonly used to provide power for portable construction signs, emergency telephones, and remote industrial facilities. ZENSOFT solar systems becoming popular as a way of supplying electricity for remote power applications such as homes and cabins that are located away from power lines, for sailboats, recreational vehicles, telecommunications facilities, oil and gas operations, and sometimes entire villages-in tropical countries. Solar panels make electricity in all kinds of conditions, from cloudy skies to full sunlight, in all seasons of the year. But they don't work at all during the nighttime! To make electricity available after sundown, the energy must be stored during the day for later use. The usual storage device is a rechargeable battery.

The batteries used with solar arrays will discharge and recharge again many times. They contain special parts and chemicals not found in disposable batteries.

Besides solar panels and rechargeable batteries, ZENSOFT Solar systems are equipped with electronic charge controller. The main job of this charge controller is to feed electricity from the solar panel to the battery in the most efficient manner and to prevent the solar panel from overcharging the battery. The charge controller also protects the solar panels from electrical damage.

In many cases, people need the electricity stored in the rechargeable batteries for use with normal household appliances. The problem is that most of those appliances require 230 volts (AC), whereas the battery puts out only direct current (DC), usually at a much lower voltage. A device called a power inverter solves this problem by converting the battery's low-voltage direct current to 230 volts (AC). Our charge controllers equipped with own built-in power inverters.

The Green Energy source makes many people consider them a great alternative to gas-powered generators or connections to the regular electricity supply. Some countries such as Japan have encouraged businesses and communities to install solar panels on the roofs of new buildings to reduce the need for electricity from other sources.

Many homes and businesses have both a connection to the commercial electrical supply system (often called the "electricity grid"). The solar panels can provide all or most of the building's electrical supply during the day, and the grid supplies whatever other electricity may be needed during the night. In some cases, the panels make more electricity than is needed in the building, and the excess is sold to the TNB. This results in the TNB sending the building owner a cheque instead of a bill!
