How To Buy A PV Solar Panel?

The very basic reason why we are still not using solar energy to power our needs is because it is not a feasible project and the returns in terms of economic benefits are less. Does that mean we should give up the idea of installing a solar panel in our house? Of course not, in order to prevent your solar project budget from going out of bounds, what you need to do is to get yourself familiarized with the current market prices and identify sellers who can give less than the market price. This requires a lot of market research, a systematic study and accurate calculation on the project budget. Only then you will be able to find out who can offer you cheap solar panels which can minimize your project cost and will soon give out quicker returns. This article shows you how to choose the right solar panel which is both cheap as well as quality.

Following are the key aspects that need to be considered before deciding the project cost of your solar panel apart from selecting the price of the panel. This is because the price of the solar panel cannot alone determine the cost of the project. The installation cost of the solar panel plays a very important role in determining the project cost. The installation cost can be determined on five factors.

1) The wattage rating of your solar panel.

2) The brand of the panel to be installed.

3) The warranty period offered by the panel.

4) The size of the panel that you have chosen.

5) The certification obtained by the solar panel manufacturing company.

However when it comes to choosing the solar panel, not everything depends on the cost. Before purchasing the panel, you must decide the place on your house where you will be installing it. If there is not set up anywhere on your house where you can set up the panel, creating one should be your first priority.

This involves considering two important things.

First is the place where you wish to install your panel should be able to accommodate everything that comes along with the panel. It means your house backyard or rooftop should have enough space so that your solar panel can sit comfortably.

The second thing is that this comfortable place should be in a place in your house where it receives maximum sunlight.

You must also make sure that a particular solar panel allows you to benefit from the government subsidies and whether the warranty period covers the recovery period or not. There are 2 points that you must ensure are satisfied.

1) First is to make sure that the solar panel that you by has a very long life. A good quality panels have abut twenty five years of life.

2) The second thing is to ensure that your warranty period goes beyond or up to the recovery period.

In other words if the warranty period of your panel is 12 years, then you must make sure that you are able to recover within that period.

The wattage rating of a solar panel determines the price of the panel. You must be very clear in your monthly wattage requirement in order to determine whether a particular solar panel with a certain wattage rating would be enough for you or not. The last and the most important thing is the efficiency of the solar panel. The recovery period of you panel is inversely proportional to the efficiency of the panel. The highest quality of solar panel manufacturers claim to achieve about forty percent efficiency. Also it decides the cost of the panel so you need to decide based on your budget.
