Frequently Asked Questions About Solar Installers

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 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.

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.
