Frequently Asked Questions About Solar Installers

Have questions about going solar? Find answers to common inquiries about solar panel installation and connecting with reputable Solar Installers in UK.

How do solar panels work?

Solar panels work by converting sunlight into electricity using photovoltaic cells made of silicon. When sunlight hits a solar cell, it creates an electric current. Multiple cells are wired together to form a panel, and multiple panels can be combined to create a solar array.

What is net metering, and how does it work?

Net metering is a billing mechanism that allows homeowners and businesses with solar panels to sell excess electricity generated by their system back to the utility grid. When your solar panels produce more electricity than you consume, the excess is sent to the grid, and your electric meter runs backward. You receive credits for this excess energy, which can offset your electricity bill. Net metering policies vary by location, but they generally make going solar more financially attractive by allowing you to earn credits for the electricity your system generates.

What is the lifespan of solar panels?

Most solar panels have a lifespan of 25-30 years or more. Even after 25 years, panels will still produce electricity, but their efficiency may gradually decline over time. Reputable manufacturers offer warranties that cover defects in materials and workmanship for a significant portion of the panel's lifespan.

What is the difference between grid-tied and off-grid solar systems?

Grid-tied solar systems are connected to the utility grid, allowing you to:
  • Draw electricity from the grid when your solar panels aren't producing enough power (e.g., at night)
  • Sell excess solar electricity back to the grid through net metering.
Off-grid solar systems are not connected to the grid and rely solely on solar panels and battery storage for electricity. They provide energy independence but require a larger upfront investment for batteries and a larger solar array.
