Frequently Asked Questions About Solar Installers

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.

How can I finance my solar panel installation?

Various financing options are available for solar panel installations:

• Cash Purchase: The most straightforward option, providing the greatest long-term savings but requiring a larger upfront investment.
• Solar Loans: Loans specifically designed for solar installations, often with favorable terms and interest rates.
• Solar Leases: A third-party company owns the system and leases it to you, allowing you to go solar with little or no upfront cost, but you won't own the system or receive tax benefits.
• Power Purchase Agreements (PPAs): Similar to leases, but you pay for the electricity generated by the system, not the system itself.
• Home Equity Loans or Lines of Credit: Borrow against the equity in your home.

The best financing option depends on your financial situation and goals. Consult with a solar installer and a financial advisor to determine the best choice for you.

How do I know if my roof is suitable for solar panels?

A suitable roof for solar panels should have:

• Adequate Sunlight: Unobstructed sunlight for a significant portion of the day.
• Sufficient Space: Enough space to accommodate the desired number of panels.
• Structural Integrity: A strong roof structure capable of supporting the weight of the panels.
• Appropriate Orientation and Tilt: Ideally, the roof should face south (in the Northern Hemisphere) or north (in the Southern Hemisphere) with a tilt angle close to the latitude of your location. However, other orientations and tilts can still be effective.

A qualified solar installer can assess your roof during a site visit and determine its suitability for solar.

What are the different types of solar inverters?

Solar inverters come in several types:

• String Inverters: Connect multiple panels in a series (a 'string'). A cost-effective option for simple systems, but a single panel issue can affect the entire string.
• Microinverters: Attach to each individual solar panel, maximizing energy production even if some panels are shaded. They are more expensive but offer greater efficiency and monitoring capabilities.
• Power Optimizers: Similar to microinverters, but less expensive. They optimize the output of each panel and provide individual panel monitoring, but a central inverter is still required.
• Hybrid Inverters: Combine a solar inverter with a battery charge controller, allowing for seamless integration of battery storage.

The best type of inverter for your system will depend on factors like your budget, roof layout, and energy needs.
