Things like solar panels are things you buy once in many years. Because of this, you hardly know a thing about them. All there is to go on is the information we get from adverts and sales agents. One problem about these, though, they all claim that their solar panel is the best.
Surely, that cannot be true. Either one of them is lying, or all of them are lying. So if the information from the adverts and sales agents are misleading, what should you go for?
Here are a couple of things that will help you get the best solar panel
Specify, which type exactly do you want?
Solar panels come in different types. Each type is suitable for a particular use. Now, you might know all the types there are, but you might not have a clue which one suit your situation. First of all, know what you want it for.
Is it back up to your house? Is it to run heavy machinery? Is it for lighting only? Once you have known the exact purpose it will serve, decide on the type you want. This will help you avoid having a panel that is inefficient.
Check for the efficiency of the panel
Efficiency refers to the ratio of the sunlight energy hitting the panel to the electrical energy it releases. It means that if the panel efficiency is 25%, then the electrical output will be just above 25%. Depending on the purpose it will serve, the efficiency will dictate the type of panel you will buy.
In as much as the efficiency is good, you will realise that as the efficiency goes high, the price rises too. So the disadvantage of efficiency is that you will have to pay more to get the highest of best efficiency.
It will dictate the brand, size and quality of the panel you will get. There is no way you can buy a panel that costs 1000 Euros when your bank account has 800 Euros. After you have looked at all the factors and decided on what you will want to buy, it all comes back to the price. If you cannot afford the best, go for the next best thing.
It is one way of knowing the quality of panel you will be getting. Here is how to read manufacturers; manufacturers who are confident of their products will give you even more than five years of warranty. It is because they know that even in the next five years, the product will still be in good shape.
Companies that are not confident in their panels will give you a warranty that lasts a year or months since they know the product will not last for long. Therefore, when buying a solar panel, go for one that has warranty that lasts long.
This is not a very efficient way of looking for a panel. You will realise that only one product of a given company is actually effective. The remaining are not that good. For instance, if the company you like produces excellent electrical appliances, it does not mean that they will have the best panels as well. Look at the specifics.
