In addition, Horizon Energy Systems uses a better- than-industry-standard architecturally designed mounting system that places the solar modules together without gaps and at a low profile close to the roof.

At Horizon, the usage needs of the customer drive the engineering design. Unlike large home improvement stores that may offer two or three choices, Horizon customizes the system size so that ultimately the customer won't have an energy bill.

Horizon bids are comprehensive—there are no extra costs down the road. Consumers should be weary about bids that don't include all associated costs, especially permits. Be careful to understand ratings on bids as well.

The panel rating is very misleading. Instead, look for the output of system rating which is the only real way to accurately gauge output.
