System Sizing
How Many Solar Panels Does a Long Island Home Actually Need
There is no single answer that works for every roof. The right number of panels depends on how much electricity your household uses, how much usable roof space you have, and how much sun that roof actually gets once trees, chimneys, and neighboring structures are accounted for.

20–30
panels, though your actual number depends on usage, roof space, and shading. A generic online calculator built around national averages will not get this right
1
Your Actual Electric Usage
We start with your past twelve months of PSEG Long Island bills rather than a rough estimate. A household running central air through a Long Island summer uses more than the national average, and sizing off that average leaves you short in July and August.
2
Usable Roof Space
Not every square foot of roof counts. Dormers, chimneys, vents, and shaded sections all reduce the space available for panels, which is why two homes with the same total roof size can end up needing different system sizes.
3
Roof Orientation and Shading
South facing roof sections produce the most, but east and west facing sections still contribute meaningfully across a full day. A mature tree or a neighboring two story home can shade a section enough to change how many panels it can support.
4
What You Want the System to Cover
Some homeowners want to offset their entire bill. Others want to cover a specific portion and keep a smaller upfront cost. Both are reasonable goals, and the right panel count depends on which one you are actually solving for.

If you are handy and considering a small off grid project, a self install can make sense. For a full home system that needs to survive Long Island winters, pass inspection, and connect to PSEG’s grid, licensed installation is what makes the system actually usable.
Roof Compatibility
Does Your Roof Type Work With Solar
Most Long Island roofs can support solar, but the right mounting approach depends on what is actually up there. Because we install both roofing and solar, we look at compatibility from the roof’s perspective first, not just the panels.
Most Common
Asphalt Shingle
Standard penetrating mounts are well understood on shingle roofs and make up most of our Long Island installations, with proper flashing at every mount point.
Zero Penetration
Metal Roofing
Ballasted Racking
Flat or Low Slope
Inspect First
Older or Aging Roofs
Battery Storage
Adding Battery Storage to Your Solar System
A battery does not replace your solar panels, it changes when you use the power they produce. Instead of sending unused daytime production straight back to the grid, a battery holds it for you to use later.
Without a Battery
Daytime production your home does not use right away gets sent back to the grid, and any usage after dark or during an outage draws from PSEG instead of your own system.
With a Battery
That same daytime production is stored and available in the evening, and a properly sized battery can keep essential circuits running if the grid goes down.
Power During an Outage
Long Island sees its share of storm related outages. A battery sized for your home’s essential circuits can help keep lights, refrigeration, and key systems running while the grid is down.

Not Every Home Needs One on Day One
We can walk you through whether a battery makes sense for your home as part of your solar consultation, rather than treating it as an automatic add-on every system needs.

Frequently Asked Questions
01 How long does it take to install solar panels?
On most Long Island homes, the physical installation takes one to three days once permits are approved and equipment is on site. The full process from initial site assessment through PSEG Long Island’s final interconnection approval usually runs several weeks, since permitting offices across Nassau and Suffolk County and PSEG’s own review queue take longer than the install itself.
02 When is the best time of year to install solar panels?
03 Does installing solar panels void my roof warranty?
04 What permits do I need to install solar panels?
05 How do solar panels work on a house?
06 Does installing solar panels increase home value?
Many Long Island buyers view an owned solar system as a value add, especially with PSEG rates climbing the way they have. The actual effect on resale value still varies by neighborhood and home, so it’s a reasonable factor to weigh alongside energy savings, not the main reason to go solar.
