Your home comes before the panels.

What a system includes

Panels on the roof, an inverter that turns their power into the kind your home uses, wiring and safety equipment, and usually a permit and approval from your delivery utility before it is switched on.

What decides whether it makes sense

• The roof's condition, direction and shade.
• How much electricity the home uses, and when.
• Your retail electric plan's current terms for energy sent back to the grid.
• Charges on your bill that stay the same with solar.
• The total price and any financing terms.

Reading a proposal

An estimated monthly saving is the result of assumptions about your usage, your plan and the future. Ask for the assumptions in writing, compare them with your own bills, and take time to decide. No proposal can guarantee future rates or plan terms.
