Gardiner, Maine - Solar Hot Water

Great news for Mainers ready to start kicking their oil habits – Biddeford Savings Bank is now offering a 7.99% APR loan program for financing solar energy projects and other efficiency upgrades.

With home heating oil averaging $3.67/gallon in Maine, financing a solar hot water system makes it possible for many homeowners to save more money in fuel costs than they spend on the loan note.

Why Financing Solar Hot Water Makes Fiscal Sense

More than 400,000 homes in Maine heat with oil, and many of these homes get their domestic hot water supply off of a high mass oil boiler. While this solution makes some sense in the wintertime, when the boiler is already running for space heat, in the summertime boiler efficiency is terrible – as low as 20% – leading to unnecessary waste from poor boiler efficiency and standby losses.

Solar hot water systems allow these homes to heat their water nearly entirely with solar energy from May through September (yes, even in Maine). With the boiler now largely dormant in these months, these homes will see a fuel oil savings of roughly 350 gallons of oil a year. That’s a savings of $1,284 a year and set to increase as oil prices continue climbing.

Now, with a solar hot water system averaging $12,500 gross, and around $7,750 after state and federal incentives, by paying cash the payback is less than 7 years. With financing that payback can be nearly instantaneous.

By putting down not quite half of the cost of the system, which is largely reimbursed by federal and state rebates, a homeowner can make a cash flow positive investment in solar hot water starting year one.
