What To Know Before Buying Solar Panels?

Installing solar panels can significantly reduce the cost of your energy bills. To get the most out of solar, you need to consider the factors below.

Power Requirements

Prior to buying solar panels, you need to assess your power requirements. You can do this by taking a list of all your electronic equipment. Once you have compiled this list, check on the Watts component. This information can also be retrieved from the manufacturer’s data sheet or their website. You also need to establish whether you need the solar for lighting, commercial, residential or industrial purposes. You do not have to worry about determining your power requirements. A good solar installation company will do the computation and advise you on the number of solar panels you need.

Efficiency

A solar system is an investment, and you should invest in an efficient system. Effectiveness is measured with reference to power output. Solar power efficiency refers to the rate at which the panels convert solar energy to power. If you go for higher efficiency, then you will require fewer panels to do the same job. This also means that you will need less space to have the same panels installed. Solar panel efficiency should inform your choice of panels. Quality panels should have an efficiency of at least 20 per cent.

Roof Type

Homes have different roof types and some may need more effort and will cost more to install solar panels. The good thing is that solar panels can be installed on almost any roof type. Get a roofing company or solar company to assess your roof and check if it can be modified to allow for an easier installation. In addition to the roof type, sunlight exposure will also influence the number of solar panels needed. Tall trees or buildings near your building can also limit sunlight exposure. More sunlight means more energy. Again, seek expert help to determine the best angle to have the panels installed.

Manufacturers Credibility 

It is imperative that you consider the manufacturers’ credibility. There are many solar panel providers out there. While they may all offer solar installation, some use substandard panels. You need to check that the brand you get is reputable. Check its history, efficiency and annual performance. You can also get useful reviews online on some of these solar products. It is also imperative that you check the warranty period. A good product should have a warranty of 20 to 25 years. Reliable brands are more expensive, but you will save you more in the long run.

Customer Support 

If you are installing solar power for the first time, you will have many questions. You need to work with a solar installation company that offers round the clock customer care services. Many companies are just out to sell their products without providing advice or follow-up services. A solar company worth its salt will monitor the installation and performance after installation. They will also be available to answer any questions and address any issues that arise. Choose a local and reputable company to install your panels.
