Frequently Asked Questions About Solar Installers

What happens to my solar panels during a power outage?

During a power outage, a grid-tied solar system without battery storage will automatically shut off for safety reasons. This is to prevent solar energy from backfeeding into the grid and posing a hazard to utility workers. If you have a battery storage system, your solar panels can continue to provide power to your home during an outage.

How do I maintain my solar panels?

Solar panels require minimal maintenance. Here are some basic maintenance tasks:

• Keep Panels Clean: Clean panels periodically to remove dirt, debris, and bird droppings, which can reduce efficiency. Rainfall usually cleans panels adequately, but you might need to hose them down occasionally.
• Visual Inspections: Regularly inspect panels for signs of damage, loose wiring, or other issues.
• Professional Maintenance: Consider having a professional solar installer inspect your system every few years to ensure optimal performance.

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.

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.
