They Stood By Me

I was a DIY solar power wannabe... that is 'til I connected with Manny... The man's a prince! He not only knows his stuff; he walked me through all things electrical. To make sure I had all I needed... he gave me his cell phone # to text him anytime I got confused... nights and weekends included. The prices were very competitive... definitely go with Manny -- you won't go wrong!

Bruce D.

Awesome Service!

I am always hesitant to buy things at places I have never shopped... I want to give a shout out to Manny who with great patience and knowledge helped me get my orders... I felt valued as a customer and I will definitely be back in the future. I highly recommend them, they make you feel like family.

Jennene A.

Real Person, Honest Service.

I'm about to go off grid. I called Manny, he walked me through everything so I could truly understand what I needed and never tried to upsell me. He was honest and made a customer for life.

Ray B.

Easy Return

I would personally like to thank Manny... I purchased the inverter and decided I needed to return it... Manny was very understanding and went out of his way to help me return the product and not even have to pay for shipping return. He gives this company reputation, honor and quality customer service!

Roger V.

Totally Off Grid.

I have been talking with Manny the owner... He has not only helped me design a system but he's been assisting with the install and components. I am super pleased so far with the assistance.
