Nothing’s more important to the success of your solar project than the place the panels will be installed. Will your home and property let you get the most out of your solar system? Consider these six factors, and always get a professional solar site evaluation before buying.
Panels in the Pacific Northwest may produce significant energy, but every site is different.
Roof-mounted panels are most common in cities where ground space is limited. The roof must be of sufficient size to allow enough panels to be installed to meet a significant portion of the home’s needs. Ground-mounted panels can be a good option in rural locations or where shading makes roof mounted systems ineffective.
South-facing panels usually produce best, followed by west and east orientations. North-facing panels are usually discouraged, and won’t qualify for incentives.
Trees and structures may block sunlight during part or all of the year, and this can reduce viability significantly.
Your roof should have at least five years of useful life, or else be replaced by the time solar panels are installed.
A modern electrical panel and code- compliant wiring are needed. Any needed electrical upgrades may incur additional costs. Wall space is also needed to mount an inverter.
