How long does it take for an owned solar panel system to pay for itself?
It typically takes 6 to 9 years of electricity bill savings to fully recoup the initial cost of a residential solar system in Glen Mills, PA. Because TerraSol Energies focuses on systems built for outright ownership rather than third-party leases, you keep 100% of the energy savings once the system is paid off, allowing you to enjoy free electricity for the remainder of the panels’ 25-plus-year warrantied lifespan.
A Homeowner from Glen Mills, PA was in the market for replacing his roof. He elected to switch from an asphalt shingle roof type to a much more durable, longer-lasting material: metal standing seam.
A new metal rooftop has an impressive life expectancy (approx. 40—70 years!) and for the homeowner, this presented a prime opportunity for long-term benefits that would go beyond reliable shelter. Specifically, it would be an excellent chance to incorporate a PV solar system for his home.
When considering a home solar system, it is a good rule of thumb to consider the current age of the roof. If the roof hasn’t been replaced in decades or is nearing the end of its life cycle, it is beneficial to replace the roof prior to solar installation, so that both warranties are good for 25 years and beyond.
He approached TerraSol with the goal of incorporating a solar system that would offset as much of his existing power usage as possible, without damaging or voiding the warranty of the roof.
TerraSol was great to work with. They were super professional and extremely easy to work with. They were happy to answer all of the 1000 questions I had before we signed anything and at no time felt like I was being pressured. They have a great working relationship with Peco and found ways to expedite the permitting process as much as possible. The install went extremely smooth with no issues. I would strongly recommend them for anyone considering installing a solar power system on their home or business.
Glen Mills is an unincorporated community located in Concord Township; its ZIP code (19342) covers several neighboring communities, almost all of which are in Delaware County. Since every property is unique, every system we design is unique as well.
We do not use high-pressure sales tactics. We design solar panel systems that our clients own outright, tailored to their property, budget, and electricity consumption.
Here’s what we look at before we put a price in front of you.
Roof age. If your roof is nearing the end of its lifespan, it is wise to replace it before installing solar panels; this ensures both warranties can cover 25 years or more.
Roof load. On average, our roof-mounted systems add only 3 to 4 pounds of weight per square foot.
Weather. We design our installations to withstand snow loads of 35 to 40 pounds per square foot and sustained wind uplift of up to 115 miles per hour (approximately 185 km/h).
Your energy needs. We size the system based on your consumption and financial goals, rather than simply filling the entire roof surface.
The utility company. We coordinate the work PECO needs to connect your system to the electrical grid.
Owning your own solar energy system allows you to generate your own electricity and lower your monthly energy bills.
The initial cost depends on your roof, your energy consumption, and the options you choose, such as adding batteries. Here are typical figures for purchasing a residential system to reduce your energy costs:
6 to 9 years – Typical time for utility savings to cover the cost of an owned system
100% – Share of the energy savings you keep when you own the system
Savings for businesses can be significantly higher. The fastest way to get an accurate estimate is to request a personalized solar proposal from our team of experts.
