Tips For Buying Solar Panels

Buying a solar panel can be an exciting experience, but don’t get too distracted with the advertising. When you are about to buy a solar panel, make sure you carefully check some vital aspect of the panel and various packages that manufacturing companies are offering. Also, be sure to inquire about some incentives and tax credit facilities that solar power companies offer, both at state and federal levels to help you minimize the cost of purchasing a solar panel by thousands of dollars. It’s very important you concentrate on the significant aspect of your purchase since it will be an investment and one you will be having in your home/office for long.

Below are some useful tips I’ve put together to help you focus on what’s vital when buying a solar panel:

Duration of manufacturer’s warranty

This is very important, so you don’t go buying substandard product’s that are faulty and can’t be replaced. Carefully check what the manufacturer’s warranty is covering. If the manufacturer is of high repute and the warranty on the solar panels is at least 25 years, you would expect your solar panel to last long. However, for a manufacturer to regard the warranty as valid, the manufacturer must still be in operation; so, avoid brands without a good track record.


Consider how much power your home needs. If your electricity bill clearly explains the amount of electricity you use on a 24-hour basis, you can easily calculate how many watts your solar panel array will have to generate in order to meet your needs at home. The sun is highest during the peak hours of the day, at this time the solar panels can operate more efficiently, the output can be between 40 watts to 200 watts. Generally, the difference lies in the technology, size, and price of the solar panels.

Choosing the right material

Pay close attention to this as it is quite necessary to consider the type of material used in manufacturing the solar panel so that you can choose the best material when buying a solar panel. There are 2 different materials used in producing a solar panel. Carefully consider the pro and cons of each material so as to make the right decision.

The first material is monocrystalline. It contains uniform crystals made from large, pure silicone crystal bars. The large, pure crystals supply the panels the increased efficiency since there is no unused space between the crystals. The evenly spaced nature of the panels makes all the crystal face the same direction. This means it cannot absorb light at different angles, however, if placed in the proper direction, in substantial sunlight it can absorb great amounts of solar energy. They are more suitable for smaller spaces. They are very expensive and fragile because they are more efficient.

The second material is polycrystalline. It has a crystalline structure which is formed and purified to make a pure crystal panel. They are not as efficient when compared to monocrystalline and they are not expensive. In some circumstances due to their misaligned structure, it absorbs more light from different angles. They are most effective in low light conditions and tend to have a more intense shade of blue where the random crystal arrangement can be seen. It would interest you to know that these panels have a longer life span and work best in dull weather.
