SYSTEMS

ON-GRID

Designed to supplement a traditional grid-tied power supply, these systems are used in the vast majority of North American residential installations.  They generally consist of roof mounted solar panels with integrated power inverters connected to a building's electrical panel.  These systems don't store energy on-site for later use, but rather send it directly to the local utility company in exchange for a decreased bill.

There are a number of state and local incentive programs available to help finance these systems.  See INCENTIVE section below for more information.

OFF-GRID

These systems are generally larger than their on-grid counterparts, because they provide all of homes power needs 24 hours a day without the load-sharing benefits of an on-grid system.  These systems store power on-site in battery banks which require additional investment, space and maintenance.

INCENTIVES

Database of State Incentive for Renewables and Incentives - (DSIRE)

"Free and open resource, providing valuable information on thousands of policies and incentives for renewable energy and energy efficiency."

CALCULATOR

National Renewable Energy Laboratory (NREL) - PVWatts Calculator

"Estimates the energy production and cost of energy of grid-connected photovoltaic (PV) energy systems throughout the world. It allows homeowners, small building owners, installers and manufacturers to easily develop estimates of the performance of potential PV installations."

SYSTEM DESIGN AND INSTALLATION

Although all Eco-Haus Homes are designed to accommodate solar systems, the micro and macro environmental influences of each building site require site-specific analysis and design.  A&R Solar can design and ship systems anywhere in North America and install anywhere in Washington and Oregon.  Please contact their sales team for more information.
