Cost Of A Solar Panel

When deciding to install solar panels on their property a lot of people want to know what that cost of a solar panel is approximately so that they know how much money to rise for this process.

A lot of them will have a major surprise when going into shops that sell solar panels because they will see that solar panels of the same size have different prices. This has a logical explanation. Even thought they might have the same size, solar panels might not produce the same amount of electricity. This is happening because some solar panels might have a longer predicted functioning age than others, some might have a different quality in what concerns the solar cells installed on them and some might just have been produced with a more expensive technology. If consulting with an expert you will be told that as technology modernizes the quality of the solar panels increases and this is why the cost of a modern solar panel might be higher than the cost of the last year’s solar panels.

In order for you to understand better here is and example that will illustrate why the cost of a solar panel varies so much from one year to another. Let’s say you buy two solar panels of the same type and of the same price. You install one of the solar panels on your roof and use if for two or three years. The other solar panel is kept in a safe place. At the end of these two or three years of using one solar panel you will see that the solar panel that has not been used will be more valuable than the solar panel that has been used. This is because in time, after using the solar panel, the wattage output steadily decreases. This is why they have a limited lifetime of about 20-25 years of functioning. This was one situation in which the cost of a solar panel can vary a lot.

A good method for comparing the cost of a solar panel with another is to measure the dollar/watt ratio. Nowadays a good ration on a solar cell is $4.30 per watt. If your home needs a 50 watt solar panel the total cost of a solar panel will be 215 $. This should be considered when going to buy a solar panel.

A method for reducing the cost of a solar panel is building the panel yourself. You can buy scrap solar cells at a low price from manufacturers and with a little bit of electrical skills you can have your own solar panel at low cost.

As a conclusion, when going to buy a solar panel you must remember that many factors can interfere with the cost of the solar panel. You should always consult with an expert before buying the solar panel as he will tell you what kind of solar panel you need for your home or for your business and you will not waste money on a solar panel that does not cover your needs well.
