More About The Different Types of Solar Panels

As solar power has recently become more popular in a larger range of uses, the basic part which is the solar panel has had many different alterations, or in other terms has been produced in many variations. These modifications have lead to the three different types of solar panels. And these are definitely usable in residential solar power systems.

The first type and probably the most efficient among the existing optionsis the monocrystalline solar panel, or more commonly called as the mono panel. This type is named so because it utilizes a single large sheet of crystalline silicon (single crystal, the crystal lattice of the entire sample is continuous and unbroken to the edges of the sample, with no grain boundaries.). This sheet is then cut out to fit the size of the panel, making one large single cell. The conductors that catch the electrons are metal strips that are laid over the entire cell. This type of panel is used in most residential solar power systems because of their efficiency, not to mention that fact that they are not really that expensive.

The next type is the polycrystalline panel, or the poly panel. This, on the other hand, uses a lot of small crystalline silicone cells instead of the large sheet of the mono panel. There are also two types of poly panels, the cast polysilicon and the string ribbon silicon.

Another type of panel used in residential solar power systems is the thin film panel. This type of panel is very different from the other two discussed earlier as it does not use any type of crystalline silicon. Instead, the silicon it uses is not in any crystalline form but rather it is applied directly on the panels, which allow it to use different types of semi-conductors. This is the cheapest among the various types of solar panels available because the manufacturing process is easier and costs less. Flexible panels are also possible to create. But this type of solar panel is known to be less effective than the crystalline silicon based ones because it has higher levels of impurity.

The Three Popular Kinds of Residential Solar Power

If you are looking for ways to install a residential solar power system in your home, there are different types that you can actually choose from. These different types have their own advantages and drawbacks that you can use to determine which type is suitable for your home and which one will be able to satisfy your energy demands.

The grid inter-tied residential solar power system is one of the most common types used in residential houses today. Here, the solar power system is directly attached to both the home and the conventional electric utility grid. This type of power system gives the homeowner the freedom to easily switch from solar power to the electric utility system and vice versa whenever they need to. What makes this advantageous is that when the home needs more energy than what the solar power system is producing, it can easily draw the power from the electric utility. It also has fewer required components, so it costs lower than most of the other power systems sold in the market nowadays.

The next type is the grid inter-tied residential solar power system with battery back up. This generally works like the grid inter-tied system, except that there is an additional slot installed for the batteries. The batteries act as back-up power in times of power outages. And when there is excess solar energy collected by the panels, this can be stored in the batteries. In cases when there is more energy needed than what the solar power system can provide, the batteries can automatically be used before it draws energy from the electric utility. But this type of solar power system is more complicated to design and install, not to mention the fact that it is more expensive to purchase.

The last type is the off grid residential solar power system. As the name suggests, it is not directly connected to the home and the conventional electric utility system. It, instead, makes use of batteries and an electric generator. The solar panels collect energy and then store them in the batteries. After that the batteries become the main source of energy. But in the event that the home’s energy consumption is more than what is stored in the batteries, there is a need to use an electric generator to compensate for the increase in energy demand.

Preparing For Home Solar Power Installation

How should homeowners prepare for the installation of home solar power systems? This article provides useful tips on how one can correctly and safely install an alternative power source in their home, which harnesses the power of the sun to provide the much-needed electricity to power up household appliances.

Primarily, you must check the regulations on home solar power installation in your area. Although not illegal, tapping into an alternative source of electricity is usually governed by certain mandates stipulated by the country where you live. Furthermore, your government may be offering incentives for residents who use alternative energy sources, so it is better if you are aware of these in order to avail of their incentive programs.

Once you have researched your country's regulations governing solar energy and determined that it is all right to go ahead with the installation, the next thing that you have to do is estimate the size of the home solar power system that can supply electricity to your home. There are different ways of determining this, with various websites providing step-by-step instructions. Or, if you are at a loss of how to determine the size of the system that your home will need, you can ask for assistance from qualified solar panel installation companies.

After estimating the size of the residential solar power system that will provide electricity to your home, you can now choose the type of solar panel that you should use. By this time, you would probably already have a good working relationship with a solar panel installer. The installer can help you choose the most appropriate system for your home, as well as set it up to your specifications.

Solar power has now become one of the most widely considered alternative energy source that will supply electricity for the whole world in the coming future. Installing this type of power system in your home simply prepares you for what lies ahead.

High Performance Pv Panels

There are two brands in the world that produce high-performance solar panels. The Californian Sunpower and the Japanese Sanyo (now owned by Panasonic). What do we mean by the word "high efficiency". It' photovoltaic modules with efficiency that approaches or exceeds 20%. Normally the low cost panels (eg Chinese ones) stop at a yield of 13-14%, a little higher for the expensive ones.

Take for example the Hit series of sanyo, look here for the datasheet. Hit stands for Heterojunction with intrinsic Thin-layer, a mix between crystalline silicon and thin film. In this case Sanyo utilizes both technologies to increase the energy yields.

Pic on the left shows the results of a test carried out by SANYO in Garching (Germany) during 365 days between the first 1 January 2009 and 31 December 2009. In this test were used HIT-240/235 HDE4 SANYO PV modules compared with other pv competitors in the same conditions: the roof facing south, 30 degree incline, SMA 1700 BC inverter. The diagram shows that the SANYO HIT modules have an energy efficiency significantly higher than the other (source Sanyo website).

Sunpower: the E20 series (modules with power ranging from 333 and 327 watts) comes to reach an efficiency of 20%, compared to an average of 14-15% of the other competitors.

Sunpower modules got a 25-year warranty also solar panels allows you to produce more energy on the same surfaces compared with conventional models. This results in a greater conversion of sunlight into electricity, and then a smaller space occupied by the modules.

Pro:
the High Performance Pv Panels offer maximum results with minimum effort, it is certainly the best solution, both for family pv implants and for company. By installing a system by Sunpower or Sanyo-Panasoni you will be certain to enjoy efficient solar plants, covered by a warranty of 25 years.

DIY Solar Power - Pros and Cons

Solar power is a more beneficial source of energy as it does not give off toxic pollutants into the atmosphere unlike oil. For this reason, a growing number of homeowners are starting to switch to the use of residential solar power as their main source of energy in their homes.

Because of the continually rising cost of utilities, many individuals find it hard to pay their bills or feel the need to cut back in their consumption in order to accommodate their budget. Switching to solar energy by constructing your own solar panels to produce electricity is a more earth-friendly solution to rid yourself of costly monthly bills. This can be accomplished without altering your lifestyle or restricting your consumption to make ends meet.

How to make a solar panel:

the prohibitive cost of materials and installation of solar panels is one of the major downside to get solar power completely off the ground. This situation, however, is no longer an impediment to the wide scale use of residential solar power with the DIY approach. The disadvantage of doing it by yourself can take much longer than hiring professionals. You may also make mistakes that may be difficult or impossible to undo.

Kits and instructions are available online with easy to follow step by step videos so you can construct your own solar panels at home. The cost of these kits won’t even go beyond $200 if you decide to build it yourself.

One typical downside, however, is that residential solar power is only useful when the sun shines. It won’t produce energy at night or during overcast days. However, there are monocrystalline panels that can work even in low light conditions and can make the most out of the available daylight hours.

During these hard financial times, especially if you are not too sure to bring home your next paycheck, every little bit of savings help. Building a DIY residential solar power unit is a great move in freeing yourself from the bondage of the rising prices.

Stuff You Need To Know About DIY Home Solar Power Systems

Installing a homel solar power system on your own is not as difficult as it seems. But there are indeed certain things that you have to be aware of and some additional stuff to consider.

First, you must get the estimated size of your home solar power system. There are ways to compute this, and there are websites that will teach you how. Once you have the estimated the right size, you can now consult with a reputable solar power system installer to help you determine other essential things that you will need in preparation for setting up your home's new power source. A reputable installer will also be able to tell you any state-mandated requirements that you have to complete prior to installing the solar power system.

As another option, DIY solar kits are now available in the market for homeowners who would like to try building their own residential solar power system. An understanding about electrical systems is a requirement in order to assemble kits like this.

There are different advantages to be derived from using the power of the sun as a household's main source of electricity. The main advantage is related to the savings that homeowners can have in their utility costs. The home powered by solar energy is no longer largely dependent on the electricity generated by a utility company. Thus, great savings is possible and highly desirable, especially during these times when the entire world is beleaguered by skyrocketing oil prices and the inevitable depletion of traditional fuel sources.

Another great advantage attributed to home solar power is its friendliness to the environment. Here is one power source that does not require numerous machines and equipment to set up and operate. Furthermore, the generation of solar power does not necessitate the destruction of land areas. Most importantly, there are no carbon emissions when this type of power source is used.
