TerraSol Energies is a locally owned, engineering-driven solar firm serving Pennsylvania since 2009. We are not a volume-based installer. We selectively design and implement ownership-based solar systems built to perform for decades.
We do not offer leases or PPAs.
Terrasol was very professional and responsive and did a fantastic job from start to finish.

What that means:
Custom system design based on actual energy usage
Roof age, structural, and shading qualification required
Ownership only (cash or customer-financed)
Local permitting and utility interconnection coordination

The roof is near replacement
Structural conditions are unsuitable
The financial return does not meet reasonable performance standards
Quality over volume protects both our clients and our reputation.
