If you’re looking at trying to install some solar panels into your house and then the first thing that you should be looking at is the cost of solar panels. Once your solar panels have been installed into your home there is very little maintenance involved. So you take the cost of solar panel, multiplied by how many solar panels you need, divided this number by the anticipated life expectancy of the solar panels and you are near to discovering the true cost of solar power panels.
In order to find out what is the true cost of installing solar panels in the home you need to ask yourself a few questions. First, you need to figure out how many solar panels you need. The number one question is to ask yourself is how much power your house is consuming over a year. This means all the power that you are using whether it is through electricity, gas, or maybe even an electricity generator. Make a list of all your appliances. You need to list everything that needs power to run it. You must include your heat source, your oven, fridge, your hairdryer, your computers, your TV, etc. Everything must go down this list in order to get an accurate picture. Also, think about the future. This means that if you are a growing family, you are obviously going to need more appliances in the future. If you intend to run a business from your home then you will need more power to run office appliances.
So, let’s say that you are looking at how much it would cost to get solar panels for a family of four, and you have no intention of extending your family beyond that number. It’s very easy to take all your electrical appliances, then figure out what the electricity usage for each appliances. Most appliances have a label which will tell you just this. You might have to look to the label; this could be printed directly onto the machine itself. Otherwise, it could be printed on the side of the device or on the bottom. Another area where you will find this information is on the power cord itself. If your device is powered by an adapter, the rating for the amount of electricity that the appliance uses is normally printed on the adapter itself.
What happens if your actual plans only gives the number of amps and does not specify the number of Watts? Well, quite simply you take your number of amps and multiply it by 120. This will give you the exact number of Watts. This is a US conversion because the electricity and voltage in the US is 120. In most other countries, the voltage is 240. In this case you would multiply your number of amps by 240 instead of the 120 originally stated. If your electrical appliance is powered by an AC/DC transformer, it is the DC voltage that you are taking into account.
Of course, when you are trying to figure out the costs of photovoltaic solar panels and there are a few caveats. You need to figure out the average usage is of each electrical item. Just because you’re refrigerator label says that when the compressor is on it uses 350 W doesn’t mean to say that this is going to be the average monthly figure. This is because the compressor is not going to be on all the time. Also, any appliances that you have in your house that either remove heat or create heat will use the most power.
There are different ways of saving money and therefore reducing the overall cost of solar energy panels. One of these ways is to do just reduce the amount of energy that you are using. For instance, you can save money by trying to heat only one room at a time, the room that you are in. There’s no point in heating the whole house if you are going to remain in only one room. So, you should purchase heaters which will heat only the room. It’s the same also if you are trying to cool your house down with. Instead of having the air conditioning running throughout the house, cooling every single room down, either have individual units in the room that you are in (you could try to use portable air conditioning units), or why not try using a ceiling fan. Other strategies to save money are to turn off the lights when you are not using them and change the bulbs to the long life low wattage types, make sure your computer goes to sleep when you’re not using it, try to wash your laundry in cold water, and instead of putting the clean laundry into a clothes dryer purchase a clothes line or a laundry drying rack.
Analysts actually predict that the cost of solar panels is going to come down in the future. There was a shortage in silicone, which is used to make solar panels, but the shortage is almost over. So, over the next few years, you should see a big reduction in the cost of solar panels. The cost of residential solar panels at the moment is quite high. A single 60 W solar panel will cost you just under $425. A single 123 123 Watt high-efficiency solar panel module will set you back about $640.
