Which Type of Solar Panels

It’s imperitive that you realise that solar panels have two distinct funtions: generating heat and producing electricity. You also need be aware of the difference between the two as they are not interchangable However, both types can save you money and help you live a greener lifestyle.

Solar thermal collectors use the sun’s energy to heat water and other fluids, like oil. This method uses tubing in which the water runs through once heated You would use this sytem for heating pools, hot tubs etc. These panels can also be used for baseboard heating units and hot water flooring systems for heating building interiors. Once they are installed, there is usually no need for additional heating fuels. However, the systems usually require some kind of motorized pump to move the fluids.

Solar photovoltaic cells help produce DC (direct current) electricity. Most typically, they use semi-conductor material (silicon) in the panel, which interacts with sunlight to produce electricity. That electricity can be used to power household and electrical appliances, or even the entire house if the system is large enough. The panels are only able to produce electricity when they are receiving direct sunlight.

See The Many Uses of Solar Panels

In order to use a solar power system at night or during cloudy days, the electricity must be held in a battery storage system. You can purchase inexpensive lead-acid batteries (like the kind your car uses), but keep in mind that they must be filled with distilled water to maintain their charge. Some batteries are more costly, but they have particular advantages. Sealed AGM (absorbent glass mat) batteries will retain their charge without any maintenence. Freeze-resistant gel batteries are ideal for colder climates.

For both the thermal collector and the photovoltaic systems, glass panels are used to encase their collection systems, and both must have direct sunlight to function. Ideally, the panels should be installed in a south-facing location that provides optimum access to sunlight during the day. Solar panels can be used in any location to utilize the sun’s energy, but they are less effective in regions that typically have a lot of overcast days during the year.

It’s prudent to have a back-up supply in place even if you live in a sunny climate. Backup generators can be powered with biodiesel to be consistent with your green lifestyle. And you’ll be glad you have one if your battery storage becomes depleted or there is an extended period of cloudy weather.

Using Solar Power

With the civilised world faced with a severe energy shortage, it is a good idea to look to an alternate energy system for the home. It will not only support avert the energy shortage, but can also help conserve energy for the planet as a whole. Using an alternative power system is a remarkable way to contribute to a greener and healthier environment.

Considering DIY Solar Energy?

Among the alternate power solutions, the solar power system and the wind generator system are the best. Although wind power is a great idea, not everyone can implement it at our homes because of its pre-requisites. For implementing a wind power system, we need a large open space and the average wind speed in the area should be in the region of eleven mph. Be aware that, the solar panel kit is much simpler to implement. All that is needed is a flat fixing or other clear space and a reasonable amount of sunlight.

The complete solar power system has various components. People may implement different componenents according to their needs. Let’s take a look at some solar power components.

Discover The Self Build Route To Solar Power

Solar cooker: The solar cooker is one of the most popular components of a solar energy system. Let’s look at its advantages:

• Healthy cooking – Meals cooked using a solar cooker is believed to be very healthy. A small cooking box is all you need, even for a family of five.

• Variety cooking – You can boil, roast, and bake using the same system!

• No fuel – The only fuel a solar cooker uses is sunlight, which helps conserve energy resources.

• No emissions – The solar cooker neither emits any gases nor does it leave any residue. This makes it a very environmentally friendly cooking method.

Solar generator: The solar generator is a system that runs all your electrical requirements using the solar energy. This mechanism uses photovoltaic cells to convert solar energy into electrical energy. The term “solar lighting system” is also used for “solar generator.” The solar generator stores electrical energy in cells for later use. Installing a solar energy system at home is an incredible power-saving and cost-efficient idea. Imagine using all the electricity you want without worrying about the bill!

Solar thermal system: The making of a solar thermal system (or solar heating system) in your home addresses indoor temperature. You can achieve a steady temperature at your home without concerning yourself about bills. Thanks to their growing popularity, these solar heating systems have become less expensive. And once thought of as an eyesore, they have at last become more pleasing to the eye.

Just Create Your Own Solar Panels

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 similar, but there are many differences and there are a number of things that should be considered before you choose which panel to use for your home. A great set of plans for building your own solar panel is GreenDIYEnergy Reviews.

Newer solar panels are better than older models in efficiency and construction. It doesn’t matter what style of panel you are looking for, you will be better off with modern panels than you would have been even a few years ago. Even though modern panels are generally better than older panels, care should still be taken when selecting a solar panel to use as there are a lot of differences between panels. Selection should be done based on how much electricity you wish to produce and your budget.

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. There are advantages to using higher voltage panels like less power loss in the long runs of wire, however higher voltage panels are also more expensive. Home solar panels will usually output power at 12, 24 or 48 volts, though there are some panels that are even higher. It is generally best to select panels with the highest voltage level that your budget will allow.

Number of volts in your solar system will also influence which solar charge controller you choose.

Another differentiator between different panels is conversion efficiency. There can be as much as 10% difference in conversion efficiency between different panels, even though the panels may look alike. This is a big difference in the power that will be produced from a given amount of sunlight. Over the life of the panel, this difference in electricity generated will be really big. Because of this, you will need less space for panels and you will need to spend less money because you will need fewer panels. It is important to look at the efficiency rating and again select the one with the highest efficiency that 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. There are some panels that combine solar electric panels with solar thermal panels in one package. These can be used for both electricity and hot water. You will get the most efficient use of roof space with these panels and also get double the benefit.

Another newer development is panels that include a micro inverter. 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 converts the DC electricity from a solar panel or battery into the AC power that your appliances need. 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. If you’re interested in micro inverters, there is an in-depth article at Micro Inverter.

 

The First Step Toward Off Grid Living

Off grid living is becoming more appealing to many people as the cost of energy continues to increase. Unplugging from the electric grid and producing all of your own power is now entirely possible. If you size the system appropriately, you can use solar panels or wind turbines to produce all of your own power. By producing some of your own electricity, you can take at least a small step towards off grid living.

Let’s start by talking about solar power. Solar panels are a great option for supplying power to many homes and can work in all parts of the world, even in remote areas or places with a harsh environment. Some hardware and plenty of sun are the only requirements. For the do-it-yourselfer, the best guide to building a diy solar panel is GreenDIYEnergy.  Solar power systems can be big or small and can even be portable to take in your RV. Solar panels need very little maintenance, are tough and will last 20 or more years if taken care of.

Some number of solar panels wired together are primary part of any solar power system. Solar panels in the northern hemisphere should be facing directly south for the highest power output. With older solar panels, it was more important that they point directly at the sun and many solar power systems used motors to rotate the panels so they always pointed directly at the sun, however with more modern panels this is less important.With more modern solar panels, it is less important that they point directly at the sun, but older solar power systems often had motors to rotate the panels as the sun moved across the sky. With more recent solar panels, stationary panels work quite well as long as they are pointed directly south and at the correct vertical angle.  Another great resource for how to build a solar panel is Build Solar Panel.

Since solar cells produce Direct Current (DC), the electricity produced by solar cells can be used to power any DC appliance or to charge batteries. Using batteries allows for storing electricity to be used when the sun isn’t shining.

If you want to provide electricity to Alternating Current (AC) appliances like you typically have around your home, you will need a power inverter. A power inverter can be used to do the DC to AC conversion on power coming from either the solar panels or from batteries.

Wind turbines can be mounted on a tower, a pole or sometimes even the roof of your house. They are very efficient and fairly small. Wind turbine can generate power at night, which is an advantage over solar panels. A wind turbine can generate power as long as the wind is blowing.  For information about making a diy wind generator, check out Earth4Energy Review.

It is possible to combine both solar panels and a wind generator in one system. Both solar panels and wind turbines generate DC electricity so you can use the same batteries and power inverter with both. If it is overcast and windy the wind turbine can generate power and if is it a sunny, calm day the solar panels will provide power.

For people wanting to live the off grid lifestyle, either of these systems can provide enough power. They can allow you to take your first step toward complete off grid living.
