How to choose solar panels for home and business

How to choose solar panels with so much information available? The process of shopping for solar can be overwhelming. Many companies look the same so how do you tell them apart and choose the right company and system for your home or business? Here are some important factors to take into consideration when looking for a solar company.

MSC Certification

It is important for your installer to be certified by MSC. If he isn’t, you won’t qualify receive payments or the Feed-in tariff. A good installer will also be a member of the Renewable Energy Assurance Limited (REAL) or the Solar Trade Association (STA).

Be sure to find out who will actually carry out the installation as well. Is it a subcontracting company? Make sure they are MSC accredited too.

Assessment and Quote

Will the installer come to your home to give you information about which solar panels are suitable for your home? Will they suggest other ways to save energy? If an installer is not willing to make an initial trip to evaluate your needs and requirements, move on to the next candidate.

Also, find out how accurately the company can analyze your energy needs.

Accuracy of Solar System

Which brings us to the topic of the accuracy of the company’s solar system design: find out about pitch, shading and building code. Ensure that their system is not designed poorly before signing a contract. Ensure that their installation can optimize your potential savings and future usage.


Always ask the installer to provide testimonials and references from previous clients. This shouldn’t be a problem if they have been in business for a while. You may also want to ask neighbors and friends whether they have any recommendations or reviews about specific installers. Previous customers can give you a clear picture of how an installation process will go.

Ask What Happens if the System Doesn’t Produce As Expected

Many companies offer a production guarantee. Make sure you know details about the protection you will have if the system’s production falls short.


Make sure you know what kind of warranty accompanies the equipment. The average warranty duration for solar panels is around 20 years. Inverters and storage batteries usually come with a 5-10 year warranty while workmanship warranties typically last around 1 year. If an installer is offering a warranty shorter than those listed above, find someone else.

Financing Options

Several financing options may be available to you for your solar system. Which options are offered by the company you are considering do the install? Is a PPA, lease and loan option offered? Does the company recommend buying the system outright or financing?

Some companies actually steer you toward a financing option that suits them best and not you. You should be the one making the ultimate decision about which financing option is best for you. If you feel you are being pushed in a certain direction, perhaps consider another solar company that offers different options and understands your right to decide.
