Are you thinking of installing solar panels at your house, but you think it might be costly? Then you have to change your notion about it because nowadays due to the high cost of power solar energy, solar power systems are gaining popularity. While some companies offer to install a solar power system for tens of thousands of dollars in order to fully provide your home with solar electricity, you can save a lot of money starting with small things and installing solar power system independently. One of the advantages of using it is that there is no need to buy batteries on regular basis in comparison to purchasing them regularly for an inventor (equipment used for electricity). At the time smaller Solar Power system can also be installed which is less expensive and generates electricity. Even a small amount of solar panels on the roof of your house will lead to smaller payments for electricity. Solar power systems come in 2 types: on grid and off grid. Grid tie solar systems produce energy only during the sunlight. Off grid solar systems includes a battery that stores energy, i.e. your house will be provided with electricity even when the sun does not shine. There are also hybrid systems that are a combination of these 2 systems.
Let’s have a look at the main components of a home solar power system.

PV Solar Panels

The main component of DIY solar power system is the solar panel. The PV Solar panel electricity systems are also called as solar photovoltaic (PV) which captures the sun’s energy using the photovoltaic cells. This energy is the prime source for the device. The best part of this type of solar cells does not require direct sunlight for working rather these cells can also generate a great amount of electricity on a particular cloudy day. These cells can easily make electricity by converting the sunlight and it can be used for lighting and running the household appliances. These PV solar panel cells are made from the layers of silicon which is a semi-conducting material. When the sunlight comes on the cell it makes an electric field around the layers. When the sunshine is stronger it produces more electricity. It can be placed on the roof of the house. If you are not experienced in placing then try to hire a professional for the installation set-up. Each panel consists of individual photovoltaic (PV) cells. These solar cells convert sunlight into electricity. As such individual solar cells produce a small amount of energy, they are connected to one another. Then the connected solar cells are placed in a special frame and covered with special glass. The obtained solar panel is usually mounted on the roof where the sunlight is not obstructed by the trees.

Solar Batteries

Solar batteries are those which use sunlight for getting its energy and it usually takes one or two hours to get them fully charged. Solar batteries store energy generated by the solar panel for its use at night or when the sunlight on the solar panel is not received. Although there are many different batteries, lead-acid batteries are one of the best and widely used in DIY solar power systems. At the same time, nickel cadmium types of batteries are also used on solar panels. Usually the lead-acid batteries are cheaper to buy whereas nickel cadmium batteries are more expensive. Well the advantage of nickel cadmium battery is that the durability is more in long run and becomes an economical option. Battery capacity is measured in ampere-hours at a certain voltage. We must choose a battery that can store the energy enough for 5 days of functioning without the sunlight. These solar batteries can be used for lighting and on run it is very economical compared to other sources of electricity.

Solar Charge Controller

To extend the life of the solar battery you need a controller. The controller is needed to prevent the battery from overcharging and thus increasing its life span. At the same time, the solar charge controller prevents the draining of the battery completely. It does not only perform controlling the charging process but also protects the life of the battery.The controller monitors the battery voltage and reduces or stops charging when the voltage rises above normal. When the battery voltage drops, the controller allows you to continue charging. Controllers vary due to the amount of current that they can handle. It is better to buy a more powerful controller, because it is not very expensive and will handle more power. These solar charge controllers are also known as solar charge regulator and these controllers can easily monitor the battery temperature in order to prevent it from overheating. Some controllers also display important data such as mesurement of battery level along with data logging in order to track the electric flow in a specified limit.
