Why the Allterra Approach Is Different

We pride ourselves on doing what is best for our clients. As a referral-based business, our reputation and customer service is what keeps us growing. Below are a few of the reasons our clients love working with us:

Educational Approach

Our professional staff explains the facts and nuances of solar. We believe that when the veil is lifted on $0 down rental options like Power Purchase Agreements (PPAs) and leases, the numbers will speak for themselves and people will choose to own their system.

Professional Engineering

Our team of experienced engineers design your system from scratch to ensure that we find the best approach for your home or business. Once the optimum design is complete we match clients needing financing to the program that will yield the most savings and best return on investment.

Quality Service

Evaluate our track record, the reviews and client testimonials all say the same thing: Allterra does great work. We encourage those considering solar to research the equipment we use and the warranties that provide peace of mind for 25 years.

We will discuss your home, energy needs, future goals, and any concerns about solar you may have in a quick interview process. We’ll evaluate a few designs, verify the most advantageous way to go solar, and a consultant will explain solar options with you at your home for free.

Typically, our clients appreciate our recommendation of purchasing solar equipment, receiving the IRS Tax Credit, and moving to a Time of Use Rate Schedule where you bank electricity credits by day and buy cheap energy by night.
