Things to consider before buying Solar Panels

Solar EnergySolar panels have become one of the most popular ways of reducing energy costs in a majority of homes and industries by converting solar energy from the sun into electrical energy.

Solar energy is a clean source of energy that majority of environmentalists and scientists worldwide are advocating for its use as the best way to curb the current global warming menace.

However, selecting the right solar panel to buy can be such a daunting task given there is more than one flavor in the market. The following are some of the guidelines you should follow if you want to buy the right solar panel for installation regardless of cost.
1. Consider power tolerance

This is one of the most important aspects of a solar module that dictates its quality.

It refers to the range or percentage variation which either exceeds or meets the solar panel’s rated power rated during its production. Power tolerance is usually indicated as either positive or negative.

For instance, positive tolerance means that a solar panel can produce at or above the labelled power output and on the other hand, a negative tolerance means that the solar module will not only produce the labelled power rating but also below that value.

Therefore, select a panel with positive tolerance because it signifies that the panel is of high quality.
2. Temperature co-efficient

It is quite interesting to note that solar panels do not operate well in higher temperatures, especially at any temperature above 40 degree Celsius. A measure of how a panel operates beyond this temperature is referred to as temperature coefficient.

This factor is very vital in determining the effect of high temperatures on the performance of the panel. It is therefore recommended that you buy a solar panel with a lower temperature coefficient.
3. Size and watts

Solar panels come in different sizes and wattage that in most cases affect the way they are priced. Watts refer to the power output of each solar panel.

For example a 300Watt panel subjected to ideal conditions can produce 100 watts of electrical energy per hour.
However, prices increase with the increase in wattage. Also, it is very vital to note that the panel’s power output can also affects its physical size, for instance, a 300Watt solar panel will be three times larger than 100Watt solar panel.

You should therefore consider if the sizing and wattage of your system is enough to run your home appliances while ensuring that its size can physically fit and area you would wish to install.
4. Check for warranties

 

Majority products in the market nowadays come with warranties, especially the genuine ones.

You should therefore check if the manufacturer requires you to send the solar panel back in case of a technical hitch. Actually, this is an assurance the solar panel of high quality and hence offering values for your money.

Consider buying a solar panel that comes with warranties requiring you to pay absolutely nothing for it to be repaired or replaced.

5. Conversion efficiency

This is another factor you should consider while choosing the most suitable solar panel to buy. It refers to how the solar panel transforms light energy from the sun into electrical energy. For instance, you should buy a solar panel with high conversion efficiency if your system demands more power.

These are just but a few things to consider while selecting a solar panel for purchase. Also, you may consult an experienced and accredited professional in order to ensure that you buy a solar panel that’s of the right size, durable, money saving while producing maximum power.
