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 USA.

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.

Are there any financial incentives for going solar?

Yes, many governments and utilities offer financial incentives to encourage solar adoption, such as:
  • Tax Credits: Reduce your income tax liability based on the cost of your solar system.
  • Rebates: Direct cash payments or discounts on the purchase of a solar energy system.
  • Net Metering: Allows you to sell excess solar electricity back to the grid for credits.
  • Renewable Energy Certificates (RECs): Tradeable credits representing the environmental attributes of your solar energy generation.
The availability and specifics of incentives vary by location, so check with your local government and utility for details.

Will solar panels work during cloudy days or at night?

Solar panels still generate some electricity on cloudy days, although their output will be lower than on sunny days. They do not generate electricity at night. This is why battery storage can be a valuable addition to a solar energy system, as it allows you to store excess energy generated during the day for use at night or during periods of low sunlight.

What are the different types of solar panels?

The most common types of solar panels are:
  • Monocrystalline: Made from a single silicon crystal, known for high efficiency (typically 18-22%) and sleek black appearance.
  • Polycrystalline: Made from multiple silicon crystals, slightly less efficient (15-17%) but often more affordable than monocrystalline.
  • Thin-film: Made from thin layers of photovoltaic material, lower efficiency (8-12%) but can be flexible and lightweight.
The best type of panel for your project will depend on your budget, roof space, and desired energy output.
