Renewable Energy

The solar energy is a promising source for powering up the houses. However it is expensive to start with and therefore it is not very popular amongst the domestic users. However, the governments are encouraging their people to go solar and install the solar power system.

A solar power system is composed of numerous parts and the users must understand its composition to make the best use of the system.

Types Of Solar Power Systems

There are two main kinds of the solar power system depending upon their connection to the national grid. These are explained below:-

Connected To Grid Solar Power System

Such kind of solar systems are connected to the national power system. The amount of electricity generated by these is accounted for by the power company and any surplus energy is shared by the power company with other users.

High Costs of Electricity in USA have become discouraging for thousands of consumers. As a result, people have started looking for the alternate sources of energy. Credits and discounts are available for the installation of solar electric system for household and business venues. For instance, the State of California pays a rebate for using solar power system.

In addition, the solar power system is available on lease in a number of states. New solar systems available for domestic users provide free energy from the sun. This can be used to run TVs, refrigerators, pumps, computer and many other appliances.

Need Of The Electric Power Company

With the advent of solar electric system, utility consumers have become independent in producing power for their domestic use. Consumers do not have to rely on Power Company alone and they can meet their utility needs. However, they remain connected with a Electric Power Company.

Convenience Of Solar System

Solar system is very simple to use. It does not require any special monitoring and is a plug and play utility. In addition, there is no issue of moving parts and noise. Solar modules are assembled under the heat and light of sun and generate power through out the year. Solar modules cover a warranty of 25 years but they last for about fifty years.

Configuration Of Solar Electric System

The Solar Photovoltaic Array is a unit that collects the energy from a sun. It is placed on top of a roof in a south direction. Hence it gets maximum exposure to the sun light. Energy conversion unit (an inverter) receives energy in the form of direct current and inverts it into alternating current.

Features Of The Solar Electric System

A few salient features of the Solar Electric System are highlighted below:-

1. Functions Of Inverter

AC or alternating current is used in houses and the sockets are made to receive it. Inverter produces the AC current from the DC that it gets from the battery. This is in turn fed to a utility meter and a grid. While producing power, the utility meter may have to slow down and at times run backwards.

2. Net Metering States

Net Metering States like California charge full retail price for the power production. Consumers get a credit from company for producing the excess power. Utility companies located in a state with net metering laws, issue a credit for the full retail value of power, households or businesses consumption.

3. Credit for Excess Production

Credit for excess production is carried forward to the subsequent months. At the end of a year, the solar system power generation restarts. If any credit is remaining, it will be treated as zero. So it is important to set a yearly limit for the scale of production and consumption.

4. Batteries For A Solar System

 It is a personal choice to use batteries. Both kinds of the solar systems are available in market that runs on battery or even without them. The system automatically shuts down in case of failure with a battery-less system. No electricity is available at homes until a utility company restores the power. This is a safety measure installed by the power companies.

5. Feeding Power During Power Failure

During power failures, utility company sends a lineman to repair power lines. System does not allow an inverter to operate during power failures.

Solar inverter is a great tool that utilizes sunlight and converts it into reusable electricity. It is an integral part of a solar generator. Solar inverter can be bought separately or along with the solar panel and battery for setting up a fully functional solar power system.  If you are considering buying an inverter separately then make sure you are going to buy an inverter that matches with the wattage output of the solar panel that is installed in your home.

Working of Solar Inverter

Solar inverter works on a very simple principal that is receiving sunlight by the solar panels and conversion of that sunlight by the help of solar inverter into reusable electrical power.

Standalone Inverter

The power that is generated by the solar inverter is stored in batteries. This is the point where inverters are needed. Solar inverter converts the direct current (DC) that is stored in the battery. That DC is converted into the alternating current (AC) that is then used for domestic purpose for powering electrical equipment and devices. The inverter that performs this simple task is referred to as the standalone model.

Synchronous Inverter

In this type of inverter energy from the photovoltaic (PV) module or a solar panel is directly connected to the utility grid, in such a case a grid-tie inverter or a synchronous is required for that energy. The synchronous inverter performs the same function as the standalone inverter does. It converts the direct current (DC) into an alternating current (AC). Read the full story

Solar power energy is serving for a variety of purposes. In the past few years, more forms of solar power energy have become popular among green people. These consumers also directed towards ways by which they can keep the track of the performance and efficiency of their solar power system. One of the most popular ways to become more efficient when operating a solar power program is to utilize a tracking base. Following are the few important things about running a photovoltaic system:

Advantages of Tracking

You can enhance the energy production with the tracking because tracking-arrays get more sun power when it is at its peak. This allows the installation of a smaller array and reduces the required array footprint that is beneficial for sites that do not have much space available. Tracking array can also be beneficial for the kits with wide open solar access. The sun power that is received during early morning and late hours can be sufficient, especially during low summer times during which at most northern latitudes, the rise in the northeastern region and sets in the northwestern region.

Appropriate Applications of Tracking Array

Surplus power is only advantageous in the case when can easily sell it or store it for future use. In this case, a utility connected system with wide open sun window can be very beneficial option for a tracked array. It is because every kilowatt-hour will be utilized. Read the full story
