Solar Cell

Solar cells refer to any device that can convert the energy of sunlight into electrical energy through a process called photovoltaics. In recent times there has been a larger production of these cells and most power companies have begun investing a lot in solar cell research. The development of solar technology can be credited to the French physicist Antoine – Cesar whose research went a long way in the development of this technology. According to the encyclopedia Britannica, the first solar cell was constructed around 1883 by Charles Fritts.

Solar cells are used in various devices including calculators. Such devices often don’t use battery because they run on the energy from the solar cells.

There are several types of solar cells. Although they work on similar principles, they also have various different advantages and disadvantages.

Types of Solar Cells

1. Monocrystalline Silicon Solar Cells
These are also popularly known as single crystalline silicon. They are easy to recognize due to their characteristic outer even coloring with a uniform look which shows high purity silicon. They are usually made up of silicon ingots that have a cylindrical shape. The four sides of the solar cells are manufactured from the cylindrical ingots basically to ensure optimum performance and to lower costs. One way to tell the difference between these and the polycrystalline solar panels is that polycrystalline solar cells look very rectangular with an absence of rounded edges.

2. Polycrystalline Silicon Solar Cells
Solar Cells of this type (polysilicon and multi – crystalline silicon) were first introduced into the market in 1981.

3. Thin film Solar Cells (TFSC)
This type is manufactured through depositing several layers of thin photovoltaic material onto a substrate. They are sometimes referred to as thin film photovoltaic cells. The thin film layer cells are placed in categories based on which photovoltaic are put onto the substrate. Here are the different categories:
• Amorphous silicon (a-Si)
• Cadmium telluride (CdTe)
• Copper indium gallium-selenide (CIS/CIGS)
• Organic photovoltaic cells

Solar Charge Controller

A solar charge controller is used to regulate the energy flow for many home solar inverter systems as well as some PV hybrid systems. The solar charge controller is the most critical unit of this process, so selecting the right one is crucial in determining the efficiency of your system.

While the charger itself is roughly 5% of the total cost of the system, it controls the power management of the batteries which means it extends their life and reduces the associated costs with running the solar power system. When running an off grid solar power unit, having a solar charge controller is crucial in extending the life of the battery bank.

What a Solar Charge Controller Does

Basically, the solar charge controller has two functions:
- Prevents the batteries from deep discharging
- Protects the batteries from overcharging
Inside solar charge controllers are the “state of charge calculation (SOC) that monitors the status of the battery. The essence of what a solar charge controller does is to effectively manage the battery so you get the right amount of power needed at all times.

Good solar charge controllers are low consumption units, they are protected by tough, durable casing and feature large connection terminals. Also, they feature a user-friendly display that instantly indicates the status of the all the systems connected. So no matter your understanding of solar power, all the information displayed is easy to comprehend.

Solar Inverters

Solar panels and solar panel energy systems are growing in popularity daily. These sorts of systems can help you to save money on your utility bills, and also help you to do your part for the environment. In some cases, you may even be eligible for tax breaks for installing or investing in such a system. Every solar panel system must have an inverter. But what is an inverter? Is there only one type? If not, what are the types? Which of these types of inverters are the best for your home system? In this article, we will answer all these questions and some others.

From DC to AC

The main role of the solar inverter is to transform the solar power collected from the form of direct current (also known as DC) to alternating current (AC) which can be used safely in your home as power for appliances, outlets and so on. DC is the only type of electricity that a photovoltaic panel or system actually generates. Because of this, nearly every system must have an inverter somewhere in the system.

Getting the Most of Your Investment

You may also want to consider inverters that do more than just transform energy. For instance, many of them allow you to purchase extras, as well, as part of your inverter unit. These include things like a system to tell you about how much power you are generating and using over time, a control panel for your system, and much more. In this way, the people using the systems, as well as the local utilities (if they are involved) can really put your system to good use. Many of these extras easily pay for themselves.

Best Solar Battery

In their simplest form, solar batteries are devices that are charged by using the sun’s rays, also known as solar power. These days there are many different kinds of solar batteries which work with a solar power system in order to generate clean, free energy for the user. What kind of battery to use will depend on whether or not you plan to use your power immediately, whether you intend to store it, and what kind of solar power collection system you have.

In the past, those who used solar batteries were in the minority, but as gas prices skyrocket and oil supplies begin to dry up, a solar battery bank has become a popular purchase. Once the initial purchase is made, it can be free to charge and recharge batteries for all types of applications, including small vehicles, charging mobile devices, powering a home during an outage, and providing light and energy even after traditional batteries run out of juice.

While the draw for some may be the small startup costs and the ability to access free energy, many others have turned to solar batteries as a way to keep damaging chemicals out of the air and landfill. By using rechargeable batteries and letting go of many of the more traditional energy applications, fewer batteries will end up in landfills and fewer will have to be made. In addition, less oil will have to be drilled and combusted for other types of power.

In order to begin your own solar power storage, you will need a battery bank (which includes a battery charger), solar batteries, a charge controller, and a solar power collection system. Because there are many different types of batteries that can be used in a solar system, it is necessary to know what types are available and which work best.

Grid-Tie Solar System

Perhaps one of the best new ways that you can invest in the future of your family and the resale price of your home is to install a grid tie solar system. Grid tie solar systems are different from a traditional solar system on a home that you might think of. Generally when we think of solar panels being placed on homes we think of complete reliance whereby the house is off the grid and not supplied with power from any local Hydro company. A grid tie solar system is a way that individual homes can have a solar grid that’s tied to their local power company whereby any excess power that is produced by that solar system can be purchased from you by the power company and used in other homes on their electrical grid. This means that essentially a good solar panel kit could one day pay for itself and begin earning money for any homeowner. This offers a great investment for homeowners as the payback period on a solar system can take far less time than you may think especially if you are interested in doing a DIY grid tie.

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
Solar Panel

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.

Before Starting a DIY Solar Power Project

3 questions you should ask yourself before starting a DIY solar power project:

1. Are you sure you want to do it?
I know some people who have purchased the necessary materials, thoroughly prepared, but then they suddenly lost all desire to do it, they got tired. Are you a hundred per cent sure that you’ll finish the project and won’t stop halfway.

2. Are you willing to spend considerable time on the project?
It can takes you about 2 days to build only one panel. You should be aware that the project will take you a lot of time, because you’ll need to study in details the step by step manual. After making the 1st panel it will be much easier to make the others, and you will assemble them much faster. The most difficult part is the beginning.

3. Will you create a panel studying only textual material or with the video?
If my father didn’t have a quality instruction with the video detailing the installation steps, I think he would have failed, because my father is not an electrician and has never created anything like this. If you have only texts, some parts of the installation process can be confusing. You definitely need to have a step by step video description of the process.

That’s it. Ask yourself these questions before you start your DIY solar power project. Again, I repeat, never give up. Be extremely focused, believe that everything will be OK, and the success of the work will be provided.
