Here are some Frequently Asked Questions and answers related to solar energy and installations.
How do solar panels work?
Solar panels absorb sunlight and convert it into direct current (DC) electricity, which is then passed through an inverter to convert it to alternating current (AC) electricity, the type of electricity that homes and businesses use.
Is my home suitable for solar panels?
Homes with south-facing roofs and little to no shade are ideal for solar panels. However, there are workarounds in many cases if your home doesn't have the ideal solar roof.
What size solar energy system do I need for my home?
The appropriate system size for a solar array is determined based on energy consumption, roof space, plans for the future, and budget.
What is the payback period for a solar panel system?
The payback period varies, but estimating the time it will take for a solar system to pay for itself through energy savings can be part of an initial consultation.
How long do solar panels last?
Solar panels are made of durable tempered glass and can generate power for 25 to 35 years.
What maintenance is required for solar panels?
Solar panels require little to no maintenance, especially in the Midwest and Upper South, where rainfall is sufficient to clean them.
Can I install solar panels myself?
Installing a solar panel system involves permitting, working with high voltage electricity, inspections, and interconnection agreements with the local utility, so it may not be a DIY-friendly project unless you're an electrician.
What permits and approvals are needed for solar installation?
While local regulations vary, electrical and/or building permits may be needed for grid-tied systems.
How do solar panels affect the resale value of my home?
Solar panels may increase the value of your home by up to 4.1%.
Do I need a new roof before installing solar panels?
You don't need a new roof, but it should have a good amount of life left in it.
What is net metering, and how does it work?
Net metering is the process of sending any excess energy produced by your solar system to the grid and getting a credit on your electric bill for that energy.
What happens if there is a power outage?
A solar system alone doesn't provide power during an outage.
