Alternative Energy: Renewable Sources Of Solar Energy

1.1 INTRODUCTION TO SOLAR ENERGY

In 21st modern century climate of growing energy need and increasing environmental concern. We have to find alternative option of the non renewable and fossil fuels. There are many renewable sources available for energy production. Such as, solar, wind, biogas, and so many.

From this all sources solar is the biggest source of energy. Which is freely available and infinite source. The sun creates energy through thermonuclear process that converted in hydrogen to helium every second. That converts in heat and electromagnetic radiation. The heat remains in sun and electromagnetic radiation come out in the space.

Only a very small amount of radiation reach on earth but that is indirectly source of energy. Much

Such as heating, cooling, electricity etc.

1.3 GENERATION OF ELECTRICITY:

Beside solar use for heating and cooling, solar can directly converted electricity. In our home nearer all tools are designed to be driven by electricity, so by using proper solar system we can run our home tools.

The silicon components of the collector are photovoltaic cells. By their nature we can convert radiation in to electricity. This system known from more than half of century. But the generated electricity were good for little more than measuring radiation intensity. Most of solar cell operate at an efficiency of 15 to 25% which is not economical. We can get 35 to 45% efficiency by multiple junction production cells which is economical.

If it maintain its efficiency in abnormal environmental condition and does not have tendency to break down. It will be economical for power companies to build solar power facilities.

Now we know solar system generates DC power, and most appliance at home are using AC, that’s why we use inverter.

1.4 TYPES OF SOLAR INVERTER:

There are mainly three types of solar inverter which are as

It can supply energy to selected load when there is no power.

1.5 WHY WE CHOOSE OFF GRID SOLAR INVERTER?

SR.NO NORMAL SOLAR INVERTER SMART OFF GRID SOLAR INVERTER

1. No ATC (Automatic Temperature Detector) system. ATC (Automatic Temperature Detector) system available.

2. Irregular boost VOLTAGE and CURRENT for charging the battery. Regulate boost VOLATGE and CURRENT for charging the battery.

3. Possibility of battery damaging is more due to no ATC system. No any battery damage.

4. Battery backup is less after some time and life is limited. Battery backup higher than normal solar inverter and battery life extended up to 6 month more.

5. Increasing Electricity bill due to the overcharging. Minimum Electricity bill. No any problem of overcharging.

6. Cost wise running cost and maintenance is very high. Running as well as maintenance cost is very less.

7. Efficiency of this inverter is partially decrease. Efficiency of this inverter is higher.
