    Why Solar?

    Since 2012, solar install prices have come down by 90% while electricity costs have increased by approximately 97%. There’s no denying that it’s a great time to complete a solar project, but taking this step does still incur a significant upfront cost and so it’s important to do your research to ensure you choose a reputable, experienced company to work with.

    Let’s run through the key things to consider in order to choose the best solar company for you:

    Reputation: Be sure to check out a company’s track record by reading their reviews so you can gauge customer satisfaction rates and have confidence in the service they provide. Choose a company that has been operating for several years to guarantee experience and trustworthiness.

     

    Warranties: Research what warranties a company’s products come with. A comprehensive warranty ensures protection against defects and performance issues, giving you peace of mind and confidence in your investment. The best solar panels typically come with a 25 year product warranty and a 25-30 year power warranty.

     

    Product Quality: Look for certifications that signal high quality products that meet the necessary standards and regulations of the industry. The main one for solar products is the Microgeneration Certification Scheme (MCS). Although not required by law, this certificate is essential if you’re applying for financial funding through an incentive scheme. For example, the Smart Export Guarantee allows you to receive payments for exporting energy to the grid. The Home Insulation & Energy Systems Quality Assured Contractors Scheme (HIES) is another important accreditation to look out for to ensure the highest level of consumer protection.
