Solar Micro Inverters
December 3rd, 2009 | 
Author: A solar power system for your home is a great option if you want to cut or even eliminate your monthly electricity bill. The latest solar power systems are very affordable, extremely efficient, and easy to install. Recently, a device called a micro inverter has been added to solar panels, and this may prove to be one of the most useful improvements of all.There are various types of solar power inverters. You can check out Solar Power Inverter to learn more about solar power inverters.
In most cases, solar systems share the same basic setup. The solar panels are placed in the spot where they’ll be exposed to as much sunlight as possible, which is usually the roof of the home. Solar panels produce DC electricity when exposed to sunlight.
Once it’s been generated, the DC electricity goes to an inverter, which is usually located near the home’s electrical panel. One of the inverter’s functions is to convert that DC electricity to AC electricity, which can then be used in the home.
One of the inconvenient points up until now with solar power systems has been the loss of power that is suffered while the power is being transferred from the panels to the inverter. Power loss is particularly prevalent with low voltage DC electricity. Before, systems would be made with more power capacity in order to make up for the loss.
The answer to the problem of power loss is now here, in the form of solar micro inverters. Built into the solar panels themselves, micro inverters convert DC to AC electricity with minimal loss. This way, the solar panel can act as a complete solution for your energy needs. AC electricity can travel a longer distance while suffering less loss than DC electricity. This also removes the stress of having to upgrade your inverter, as the micro inverters take the stress away from the regular inverter, or even eliminate it completely, which means that you can expand your system however and whenever you wish. The initial price of these advanced solar panels is a little higher, but they’re actually less costly in the long run, as they’re so much more efficient.
Solar charge controllers are required by most solar power systems that involve the use of batteries. The solar charge controller works to control the power moving from the solar panels to the batteries. If you need information about solar charge controllers, visit Solar Charge Controller.

Solar Power Inverter
The purpose of this article is to explain the role of a solar power inverter in the home solar system, along with issues pertaining to different types of inverters, and solutions to common problems associated with them.
In the majority of home solar systems, power is initially produced by solar panels before being used to charge batteries. The solar power battery then supplies electricity to fixtures in the home. The purpose of this arrangement is to ensure that power is available even in the dark, when the solar panels aren’t actually generating power. Solar panels and batteries both work with Direct Current (DC) electricity. This has to be converted to Alternating Current (AC), which is used by appliances in the home. The conversion from DC to AC is handled by the inverter.
When it comes to inverters, there are two main types: Modified Sine Wave (MSW) and True Sine Wave (TSW). MSW inverters are the more bare-bones of the two, as they simply convert DC electricity into rough, 120v 60 cycle AC. Some types of appliances are incompatible with MSW inverters. For example, when used in conjunction with an MSW inverter, stereo equipment will often produce a noticeable hum. TSW inverters, on the other hand, have no problems in a home setting.
Maintaining an inverter requires a few precautions. Avoid putting the inverter in the same box as the batteries, but make sure it’s otherwise as close to them as possible. The wire connecting the batteries to the inverter needs to be of sufficient size. The correct size will probably be given in the inverter instructions. It’s good to have a fuse on all wires to and from the inverter. Make sure the inverter is in a place where it will not be exposed to wetness or high temperatures.
Solar power inverters are known to encounter a couple of common issues. First, there’s RF interference. Inverters produce radio noise while they’re active. Radio receivers should be placed as far away from the inverter as possible. Using a battery powered radio will also solve this problem, and the batteries can then be recharged with the solar power system.
The other issue is that of phantom loads. A phantom load is the electricity drawn by a device while it’s turned off, which is a common issue among many new TVs and other devices that use “standby” modes. Since they’re always using power, these devices keep inverters from going to sleep. The inverters then begin contributing to the problem of wasted energy, as they’re constantly in active mode. Usually, this problem can be addressed through the use of a power strip with an on/off switch. Turning the power strip off will keep the devices from drawing power, so the inverter can then go into its low power mode.

PV Solar Power Panels
Solar power systems depend on solar panels, which work to convert sunlight to electricity. Solar panels provide homeowners with the ability to produce their own energy without pollution or cost.
Solar cells themselves are built from smaller solar cells, which are contained within a weatherproof case. When they are struck by sunlight, the solar cells generate a small electrical current. When combined, a large number of solar cells can work together to produce a significant amount of current. Even if one cell fails, the others will continue working and the panel overall remains effective.
In terms of efficiency and durability, the latest solar cells are light years beyond earlier cells. With modern solar cells, you get equal or greater output even with smaller amounts of sunlight. Electricity is generated only when exposure to sunlight exceeds a specific threshold, and this differs depending on the cell. The latest cells have a very low threshold, and as such they can provide electricity for longer every day and in a greater variety of conditions.
The newest solar panels produce more energy in total than older units, and this means that it’s possible to produce enough power for everyday use with fewer panels. This means reduced installation costs and lower requirements in terms of roof space. These are some of the most frequently cited reasons why a growing number of homeowners are taking an interest in solar power.
Built-in micro-inverters have been added to recent solar panel designs. Many previous solar panel systems used just one large inverter instead, mounted near the electrical panel of the home. Solar panels generate Direct Current (DC) electricity, which would be transferred to this single inverter to be converted to Alternating Current (AC) electricity for use by the home’s appliances.
The long wires that connected the solar panels to the inverter were usually unable to completely maintain the power generated. This problem is solved by the use of micro-inverters.
The addition of micro-inverters turns modern solar panels into independent power plants, in a sense. They eliminate the need for a large inverter and make the wiring setup much easier than had been previously. Users can simply increase the number of panels as needed, building up a solar power system at their own pace.

Advanced solar power panels are a good option for anyone who is thinking about starting up a solar power generation system. Solar panels now offer more power at a lower cost than ever before. For instructions on how to build your own solar panel, visit Build Your Own Solar Panel.

Residential Solar Systems
The main component of any residential solar power system is the solar panels. They are at the heart of any solar power system and actually convert the sunlight to electricity. Many of these residential solar panels look alike, but there are a lot of differences and there are many things that need to be considered before you choose which panel to use for your home. A great set of plans for building your own solar panel is Green DIY Energy Review.
All modern solar panels are much better than older panels in both construction and efficiency. Because of these advances, any homeowner will be better off with newer panels than they would have been even a few years ago. While it is true that all of the newer panels are much better than in the past, there are a lot of differences between different models of solar panels so selecting a panel should be done based on both your budget and how much electricity you want to produce.
The voltage requirement of the system you are building is the first thing to consider. Residential solar panels have several standard voltage levels and you need to choose with one to use for your system. The decision about voltage will dictate which panels you select and also which power inverter you use. While more expensive, higher voltage panels have some advantages like less power loss in long wire runs. Residential solar panels usually have output voltages of 12, 24 or 48 volts and there are some that are even higher. It is usually best to select panels with the highest voltage level that your budget will allow.
Voltage will also dictate which solar charge controller you choose.
Another difference between different types of panels is efficiency. Even panels that look the same can have almost 10% higher or lower efficiency than similar models. This is a giant difference in the amount of electricity that will be generated with a given level of sunlight. The higher efficiency panels will produce a great deal more energy over the life of the panel. Because of this, you will need less space for panels and you will need to spend less money because you will need fewer panels. You should generally choose panels with the highest efficiency rating you can afford. If you spend a little more money now and get a better quality panel, you will get that difference back many, many times over the life of the solar panel.
Some of the newer specialty solar panels should also be considered. One type of newer panel combines both electric and thermal solar into a single panel. These can be used for both electricity and hot water. These panels will make the most efficient use of available space on your roof and provide double the benefit.
Solar panels that include a micro inverter are another newer development. A micro inverter is a power inverter that is build into the solar panel. It is sized to work with just the amount of electricity the panel outputs. A power inverter is the component that converts the Direct Current (DC) from the solar panels or batteries into the Alternating Current (AC) that comes out of the power outlets in your house. Typically a single, large power inverter is fed electricity from all of the panels or batteries and does the power conversion for the entire system. A micro inverter in individual solar panels means that you can build your system incrementally instead of having to buy a big power inverter right away. With a micro inverter you can get the benefits of AC power at each step as you build up the system. One final benefit of micro inverters is the electricity coming from the panels will be at a higher voltage and will be AC which will reduce power loss in the longer runs of wire.
