The Tri-State Area’s Top Solar Installers
Solar installation Narberth PA works best when the solar panel system is designed around your property, whether it’s a Victorian home, a newer house, a small office or a storefront on Haverford Avenue.
As an Enphase Platinum installer, we build owned systems sized to your roof, your shade and your PECO bills.

400+ Solar projects completed
Platinum Enphase Installer
TerraSol Energies, a family-owned solar company based in Chadds Ford, PA, installs owned residential and commercial solar systems in Narberth and nearby Lower Merion communities. Operating since 2009, the Enphase Platinum installer has completed 400+ projects and handles engineering, borough permits and PECO interconnection in-house.
Narberth spans approximately 0.5 square miles and lies entirely within Lower Merion Township, just a short train ride from downtown Philadelphia via the Paoli/Thorndale line.
Within this compact area, one finds Victorian-style homes, residential buildings, and independent businesses along Haverford, Narberth, Forrest, and Essex Avenues.
Each property has its own unique roof configuration, energy consumption profile, and investment budget. We do not believe in standardized, mass-produced installations.
Rather than applying a one-size-fits-all solution, we evaluate each property individually, whether it involves a simple pitched-roof system, a flat-roof commercial installation, or a design that must accommodate dormers and mature trees before making any recommendations.
Roof framing and ageOlder homes were built to different structural standards. We verify that your roof structure can support the weight of the system before any contract is signed.
Dormers, turrets, and hipped roofs reduce usable surface area. We map out each roof plane and design solar power installations tailored to these specific spaces, rather than imposing a single, massive system.
We model shading on a month-by-month basis, taking into account the trees surrounding your home, so you know exactly what performance and energy savings to expect from your system.
If you need to replace your roof in the coming years, it makes sense to do that first and save money. Otherwise, you will have to pay for the panels to be dismantled and subsequently reinstalled.
Older homes often require an electrical system upgrade before solar panels can be installed. We address this during the design phase, rather than on the day of installation.
The cost varies depending on different factors.
System size: We size the installation based on your electricity consumption data and past PECO bills, rather than a rough estimate.
Roof structure: Reinforcing the roof framework, replacing the roof, or utilizing multiple roof planes increases labor and overall costs.
Equipment choice: Panel models and their power ratings determine how much energy you can generate from a limited roof area.
Electrical upgrades: Installing a new electrical panel is often recommended, or sometimes required, for older homes in Narberth.
Your usage: Energy-efficient upgrades like a heat pump or EV charging raise or lower what you need. Tell us what’s planned.
Incentives you qualify for: Net metering credits and SREC value count toward your return. We review state and federal eligibility for every project.
If you run air conditioning, your usage likely climbs in the July and August heat. Under Pennsylvania net metering, extra power your panels make in one month earns credits that carry forward to later months, when production decreases or usage runs higher.
Any credits left at the end of the year are paid out at the price-to-compare rate. State rules also keep utilities from adding fees for net metering customers that they wouldn’t charge other customers.
Family owned: Run by the Santoleri family since 2009, with 400+ projects across PA, NJ, DE and MD.
Enphase Platinum: Platinum status in the Enphase Installer Network.
Ownership only: No leases, no PPAs, no price escalators.
Life-of-system care: Support from the same local team long after the install.
Narberth’s shopping district, stretching along Haverford, Narberth, Forrest, and Essex Avenues, is home to independent businesses ranging from various shops to an independent movie theater.
A commercial solar installation helps reduce operating costs through on-site electricity generation. For businesses with multiple locations, we help determine which sites offer the best return on investment and assist in phasing projects over time. Here are a few projects our team has completed in the immediate vicinity.
Nearby in Havertown, Chatham Park Elementary School secured a grant to install a solar system, a project we carried out. This installation helps reduce the school’s environmental footprint and provides students with a tangible example of renewable energy right at their place of learning.
399.2 kW System
475,000 kWh / yr
671 Panels
210 t CO2 avoided
For Narberth: grant funding can help schools, churches and community buildings qualify for solar. We’ve helped clients secure grants for their systems before.
The ICDD is the global reference center for high-quality diffraction data, managed by scientists from around the world. Its facility marked a first for us: the use of three-phase microinverters simplified the project and ensured optimal production over a 25-year lifespan.
88.9 kW System
115,570 kWh / yr
225 Panels
90 t CO2 avoided
For Narberth: the same panel-level approach works on any Narberth roof with shade or multiple angles, where every panel needs to perform on its own.
Our work doesn’t stop when PECO commissions your system. Through our specialized customer service team, we provide:
Performance diagnostics and operational monitoring
Solar installation maintenance
Inverter replacement
Panel removal and reinstallation for roofing work
Ongoing system performance assessment
We provide customer support throughout the system’s entire lifespan, allowing you to continue relying on the same local team long after installation and even after the warranty has expired.
Send us a recent PECO bill and tell us about your home or business. Our team will review your roof, shade, and electricity use, then give you a clear proposal with the recommended system size, expected production, and cost.
No leases, no PPAs, just a system you own from day one.
Reach our team at (888) 873-9995 or request a proposal online to start your solar installation Narberth PA project.
Installation costs vary based on system size, roof structure, the equipment chosen, and available financial incentives. TerraSol provides detailed financial modeling only after a technical assessment; we do not offer instant online quotes.
When properly designed and installed, solar panel systems do not damage the roof. We assess the roof's condition and structural capacity prior to installation to ensure long-term reliability and prevent potential repair issues.
Shade reduces output, which is why our shading analysis accounts for the impact of trees. For roofs with shade or multiple slopes, Enphase microinverters allow each panel to operate independently, preventing a shaded panel from affecting the output of the others.
Often, yes; on average, our roof-mounted systems add only 3 to 4 pounds per square foot, and we design them to withstand snow loads of 35 to 40 pounds per square foot and sustained wind uplift up to 115 mph. We first inspect the condition of your roof structure and roofing material; if the roof requires repairs, we will recommend completing them before installation.
