Most people understand the basic idea — put panels on roof, pay less for electricity. What they're less clear on is the how. How does sunlight become electricity? What happens at night? Why does the installer need to know your electric bill?
Here's a plain-language explanation of how the whole thing works.
Solar panels convert sunlight into electricity through what's called the photovoltaic effect. Each panel contains dozens of solar cells made mostly from silicon. When sunlight hits those cells, it knocks electrons loose, which creates a flow of electrical current.
This happens silently. No moving parts. No fuel. Every time the sun's out, the panels are working.
One thing worth knowing: panels still produce electricity on cloudy days, just less of it. Florida and California homeowners benefit from some of the highest solar production averages in the country — it's one of the reasons solar works so well in both states.
A solar installation is more than just panels. Here's what makes up a complete system:
Solar panels mount to your roof via a racking system and do the work of capturing sunlight. Most residential systems use between 15 and 35 panels depending on your energy needs. The racking attaches to the roof rafters — done correctly, it's watertight.
Inverter converts the electricity the panels produce (DC) into the kind your home uses (AC). There are two common types: a string inverter (one unit for the whole system) or microinverters (small units on each panel). Microinverters handle shading better — if one panel is shadowed, the others keep producing at full capacity.
Monitoring system lets you see exactly how much energy your panels produce in real time. You can track daily, monthly, and annual production from your phone. Most homeowners find this mildly addictive.
Your electrical panel and meter connect to the solar system. If you're on net metering (which Florida homeowners are, by state law), your utility installs a bidirectional meter that tracks both what you consume and what you send back to the grid.
Home batteries — like the Tesla Powerwall — store excess solar energy so you can use it at night or during a power outage. Batteries are not required for solar to work. Without one, your home draws from the grid when the panels aren't producing.
The case for batteries has gotten stronger in California, where the NEM 3.0 export rate — what you get credited for sending power to the grid — is lower than it used to be. Storing your own solar power and using it yourself is worth more than exporting it at a low rate. In Florida, full retail net metering still makes the math work well without batteries, though backup power during hurricane season has obvious appeal.
Going solar with KIN involves a few phases:
Consultation and design — We review your electricity bills, assess your roof, and design a system sized for your actual usage. You'll get a proposal with projected production, estimated savings, and costs. If your roof needs attention first, we can handle that — KIN does roofing as well as solar, and it's almost always better to address roof issues before mounting panels.
Permitting — We handle all permits and utility paperwork. Depending on where you are, this takes one to three weeks.
Installation day — A crew installs the racking, panels, inverter, and electrical connections. Most residential jobs are done in one to two days.
Inspection and activation — A local inspector signs off on the work. Your utility installs a new meter. Then your system goes live.
Start to finish — from signed contract to power-on — typically runs four to eight weeks depending on local permitting timelines and your utility.
During the day, your panels generate electricity and your home uses it first. You're pulling less from the grid, which costs less. Any surplus goes back to the grid.
Through net metering, your utility credits you for that surplus. In Florida, that credit is at the full retail rate — the same price you pay for electricity. At the end of each billing cycle, you pay for your net usage: what you consumed minus what your panels produced and sent back.
Many solar homeowners in Florida get their bill down to just the base connection fee ($10–$30/month). Some months they generate more than they use, banking credits that roll forward.
Over 25 years, the electricity savings typically run $30,000 to $50,000 for Florida homeowners, depending on system size and how electricity rates change over time. (They've gone one direction consistently for 20 years.)
Your electric bill isn't just about the panels. An old or undersized AC system can drive electricity usage high enough that you'd need a larger solar system than necessary. KIN installs HVAC as well as solar — in some cases, addressing the HVAC first or at the same time actually means a smaller solar system and better overall economics.
