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.

Do I need to replace my roof before installing solar panels?

It's not always necessary to replace your roof before installing solar panels. If your roof is in good condition and has several years of life left, solar panels can be installed on it. However, if your roof is nearing the end of its lifespan or shows signs of damage, it's advisable to replace it before the solar installation to avoid the cost and hassle of removing and reinstalling panels later. A solar installer can help assess your roof's condition and advise on whether a roof replacement is necessary.

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 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.

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.
