Solar system additions for home and business

Your solar system should grow with your energy needs. We add panels, battery storage, generator inlets and EV charging to existing systems across the Panhandle — designed around the equipment you already own, not ripped out and replaced.

Four ways to get more
from what you own

Addition 01

More solar panels for increased power

Energy needs grow — a new addition on the house, a pool pump, a workshop, a growing business, or simply a household using more than it did five years ago. Extra modules raise production and savings, and we design the expansion to match your existing array so it looks and performs like one system rather than two.

Best when: your bill is creeping back up
Addition 02

Battery storage for energy independence

Stay powered when the sun is not shining. Storage banks your excess daytime production for night-time use, cloudy stretches and outages — less reliance on the grid and far more control over your electricity. Powerwall 3 runs about $15,000 for the first battery and $12,000 for each additional; other battery manufacturers are available.

Best when: outages or night use matter
Addition 03

Generator plug installations for backup power

Do not let a blackout shut your home or business down. A generator inlet lets you keep essential circuits running when the grid goes down, integrated properly with your solar system and main panel — safely interlocked, code-compliant, and simple enough to use in the dark during a storm.

Best when: you already own a generator
Addition 04

EV chargers powered by the sun

Charging an electric vehicle from the grid undoes part of the point. A solar-integrated Level 2 charger lets your own roof fuel the car — cheaper per mile, lower carbon, and sized so your charger and your house are not fighting over the same service capacity.

Before we quote

Additions fail when nobody checks compatibility.

Bolting extra panels onto a system is easy. Bolting them on correctly is the part that decides whether you gain production or create a fault. Before we quote an addition, we check four things — and occasionally one of them is the reason we advise against the work.

  • Inverter headroom — whether your existing inverter can accept more DC without clipping away the gain.
  • Interconnection limits — what your utility permits on your service, which caps system size regardless of roof space.
  • Panel and breaker capacity — whether the main service panel can carry a battery, EV charger or generator inlet.
  • Roof life and layout — remaining shingle life, and where new modules actually belong for production and appearance.

Sometimes the right answer is a new inverter

If your existing inverter has no headroom, adding panels behind it buys nothing. We will show you both options — a second inverter or a replacement — with the production difference for each, so the decision is yours on real numbers.

Storage, in plain terms

What a battery actually does
during an outage

The most common disappointment in home storage is expecting a battery to run the whole house exactly as before. It can — with enough batteries. The honest approach is deciding what must stay on, then sizing to that.

LoadRealistic expectation on storage
Fridge, freezer, lights, internetComfortably carried, typically for a day or more with solar recharging by day.
Well pump / septic pumpSupported, and usually a priority circuit for homes outside city water.
Central air conditioningPossible, but it is the load that drains a battery fastest. Often needs more than one unit.
Electric range, dryer, water heaterGenerally excluded from backup — very high draw for the benefit returned.
Pool pumpUsually excluded during an outage; easy to run again once the grid returns.
EV chargingNot during an outage. Charge from solar and grid, not from your backup reserve.

Storage is about resilience more than savings

In Florida's current rate structure, batteries rarely pay for themselves on arbitrage alone. What they buy you is a house that keeps running through hurricane season. We would rather you understood that before buying than after.

Straight answers

Solar addition FAQs

Can I add panels to my existing solar system?

Usually yes. The deciding factors are your inverter's remaining headroom and your utility's interconnection limit — we check both before quoting. If the existing inverter is maxed out, we will show you the cost and production difference of adding a second one versus replacing it.

Can you add a battery to a system you did not install?

Yes. We add Powerwall and other storage to existing systems of any brand, including orphaned systems whose original installer has closed. Compatibility with your inverter and main panel is checked first.

How much does battery storage cost?

Powerwall 3 runs approximately $15,000 for the first battery and $12,000 for each additional unit, installed. Other battery manufacturers are available and sometimes suit a smaller backup goal better. The right number of batteries depends on which loads you want to keep running.

Will a battery let me run my air conditioning in an outage?

It can, but AC is the heaviest load in the house and will drain a single battery quickly. If whole-home cooling through an outage is the goal, plan for multiple units — we will size it honestly rather than optimistically.

Is a generator plug better than a battery?

Different tools. A generator inlet is far cheaper and runs as long as you have fuel, but it is manual and noisy. A battery is silent, automatic and recharges from your roof. Plenty of Panhandle homes end up with both.

Can I charge my EV from my solar panels?

Yes, with a properly sized Level 2 charger integrated into your system. The key check is service capacity — a charger and a battery and an expanded array all draw on the same main panel, so the design has to account for all of it.

Do additions affect my existing warranties?

Manufacturer warranties on your existing equipment remain intact; our work carries its own workmanship warranty. Where an addition touches original equipment, we document what was done so no future claim gets muddied.

Is financing available for additions?

Yes — affordable payment plans including non-collateral solar loans, so an upgrade does not have to be paid in one lump sum.
