    Understanding the Basics of Solar Installation

    The process of getting solar panels installed begins with assessing the property (either in person or with Soly’s virtual consultation) to design a customised system that covers the needs of your home. Once approved, the installer obtains permits and mounts the solar panels to the roof. They will also connect the wiring and inverters, test functionality and connect the system to the grid or battery storage so you can use the power from your solar system in your home. Regular monitoring and maintenance ensure optimal performance and longevity of the system.

    Types of Solar Panels and Installation Methods

    There are two main types of solar panels: monocrystalline and polycrystalline. Monocrystalline panels are made from highly efficient single silicon crystals. Polycrystalline panels are made from multiple silicon fragments, providing a more affordable option with slightly lower efficiency. The solar panel installation method will involve either a rooftop or a ground-mounted system. Solar installers mount panels directly onto the roof of a building, or on the ground using racks or mounts. Each method has its advantages and considerations, depending on factors such as available space, roof condition and shading.

    Spotlight on Monocrystalline Solar Panels

    Monocrystalline solar panels are known for their high efficiency, typically ranging from 15% to 24%. This means monocrystalline panels tend to generate more electricity per square meter than polycrystalline panels, making them an attractive option for a solar panel installation with limited space, such as smaller rooftops. Their sleek black appearance also blends seamlessly with rooftops for more esthetic appeal.

    Assessing Solar Installer's Track Record and Portfolio

    Key Factors to Consider When Selecting a Solar Installation Company

    When reviewing a solar panel installer’s portfolio, look for the following key indicators of reliability and quality:

    • Experience: Verify how long the installer has been in business and their track record of completed projects. More experienced installers like Soly (with over 10 years of experience) often have a better understanding of local regulations, best practices and potential challenges.
    • Credentials: Verify the installer’s certifications and accreditations, such as Microgeneration Certification Scheme (MCS) certification. These credentials demonstrate the installer’s expertise and commitment to industry standards.
    • Testimonials: Look for feedback from past customers regarding their experiences with the installer. Positive reviews and testimonials can provide insights into the installer’s professionalism, communication and overall satisfaction with the completed project.
    • Warranty and Support: Consider the warranties offered on installations and the installer’s commitment to ongoing maintenance and support. A reputable installer Soly (who offers industry-leading customer assurances) should stand behind their workmanship and offer comprehensive warranties for peace of mind.
    Evaluating Solar Installer’s Customer Projects

    Case studies and customer projects completed by solar panel installers offer valuable insights into their expertise and reliability. By examining these examples, you can assess the installer’s track record and gauge their ability to deliver successful outcomes. For example, case studies showcasing a variety of installations, such as residential, commercial, rooftop, and ground-mounted systems, demonstrate the installer’s versatility and proficiency across different projects.
