Home Solar System, 10 kW Grid-Tied


"Alto Solar was just the right blend of informative and accommodating. The 10 kW home solar project went off without a hitch and the system is performing as advertised. I would highly recommend them!"

Solar Hybrid Motorhome

1 kW Solar + 5 kWh Lithium Battery Storage


"Alto Solar helped me setup my motorhome for a 4 month trip across the US. We wanted to be able to spend time away from the grid and enjoy the vast outdoor spaces without having any power concerns. Tomi spent time understanding our motorhome and what products were most recommended for this type of application to design a robust and easy to use system that had conveniences like mobile app based monitoring. Over the course of the trip I had a few questions along the way and he provided detailed answers helping me well after installation. Tomi backs up his installs and uses quality products. Buy with confidence."
