Choice of solar panels for your home
The use of solar energy with the use of your solar panels for your home is becoming more and more popular with the awareness of its benefits amongst people increasing day by day. These solar panels transform the solar energy from the sun into usable electric power. Apart from being cost effective for people they also help in creating a pollution free environment. The technological innovations in this industry are bringing in different types of solar panels for your home and as a result, have different ranges of efficiency and pricing. The availability of these photovoltaic panels at affordable rates makes it easy for anyone to have these solar panels for their personal use to fulfil their day to day needs. In the long run, these prove to be economical for the people and help save money wasted on expensive public utility power.
There is a wide range of solar panels available for household purposes. These are priced differently. What brings in the price difference is the way these solar panels are made, their degree of efficiency and their power generating capacities. Generally, solar panels give an electricity return rate of around five to fifteen percent. The higher the return rate, the higher the cost of these panels. Solar panels need to be selected based upon the energy requirements for personal use as well as the location of the house. They are mounted in such a way that they get maximum exposure to the sun since they work at full capacity when placed properly. Solar panels for your home mainly come in four different types that are easily available to the market. These are:
1) Monocrystalline Silicon Panels
2) Polycrystalline Silicon Panels
3) String Ribbon Silicon Panels
4) Amorphous Silicon Panels.
Monocrystalline Silicon Panels
Monocrystalline panels also known as the single-crystal solar panels are made up of silicon. The Monocrystalline silicon panels have a better conductivity of electricity as they are made from one continuous sheet of silicon with pieces of metal nailed at the edges. The electricity return rate of these solar panels range from 12 percent to 14 percent. These solar panels for your home were the first to be introduced into the marketplace. They are the most dependable amongst the lot. Efficiency wise they are the best. Because of their high power generation capacity they are the first choice in houses that have space constraints. The standard 175 watt panel that is available is about 63 inches long, 31 inches wide, about an inch thick, and weigh almost 33 pounds. The minimum lifespan of the monocrystalline solar panels is about twenty-five years and can go well above fifty. So in the long run, these solar panels for home prove to be a great investment.
Polycrystalline Silicon Panels
Polycrystalline silicon solar panels are made up of multi-crystals and stand below the monocrystalline panels in terms of efficiency. Their electricity rate of return averages out to 12 percent to 14 percent, just like the monocrystalline panels. These panels are made of multiple individual PV cells that contain metal conducting materials nailed to its edges.
These Polycrystalline silicon solar panels are very cheap to produce and so they are usually high on many people’s shoppers list. The maintenance cost of these panels is also quite low as compared to that of the monocrystalline solar panels and they are equally durable. Considering the prices of these panels, and cheaper cost of maintenance, these solar panels are a great option for those who can’t afford the mono version. The downside to polychrystalline panels is that they do not last beyond 25 years though you can try to.
String Ribbon Silicon Panels
String ribbon silicon panels have an electricity retrun rate of 12-14%, just like mono and polycrystalline panels. They are built the same way as polycrystalline solar panels. The main difference, however, is that instead of being built with individual PV cells, they are made up of silicon strips. These strips function in the same manner as PV cells. The production cost of these strips are slightly lower than the cells so the cost of building string ribbon silicon panels are lower.
Amorphous Silicon Panels
Amorphous silicon solar panels stand at the bottom of the list of available solar panels to buy due to their low electricity return rate. The rate of return on these solar panels range from a measly 5-6 percent. The reason for this is the material used for making these panels. These panels are not made up of crystalline silicon. Instead, the material used is a semi-conductive metal such as copper. The production cost of these panels is very low due to the use of cheaper materials but it comes at the cost of lower quality, durability, energy production output, and efficiency.
So when you are buying solar panels for your home, it is always better to consider the cost per kilowatt over the lifespan of each panel you consider. If costs are not an issue for you, take into consideration how much fixed power you absolutely must have. The right kind of solar panels needed should be based on your own individual needs.
Solar panels for your home can turn out to be a good investment for you and your family in the long run where the returns on your money can be the nonexistence of electricity bills. Apart from being good for your pocketbook, solar panels are a great way to do your bit for nature and environment, since these produce energy without creating any kind of pollution or waste. Technological advancement is continuously trying to bring down the costs of these methods of energy production. The cost of installing solar panels for your home has gone down by as much as 40 percent over the past few years. This trend will likely continue. This in turn will make it affordable for most people to set up such systems when it use to be that only big corporations and government had access to this cool stuff.
