A 4kw solar electric system recently installed in Portsmouth, NH with premium Sunpower solar electric modules.

This just in from the NH PUC – the residential solar electric (GTPV) rebate in New Hampshire has returned! The rebate, available for systems under 5kw in capacity, is $1.25 per watt up to a maximum of $4,500 or 50% of the system cost, whichever is less.

Of the $927,964 of funding, $500,000 is already committed to waitlisted projects, so if you want to take advantage of the credit, the time to act is now! Combined with unprecedented solar electric prices (in the $4.5/watt range), grid-tied photovoltaic (GTPV) systems are an incredible deal in New Hampshire.

Here is what a 3.6kw system, enough to make out the rebate, looks like:

$16,200 gross installed cost
-($4,860) 30% federal tax credit
-($4,500) state of NH rebate
$6,840 net investment

This system locks in your electric rate for 20 years at around .06c/kWh!!!  At today’s prices, the system will produce around $750/yr worth of electricity, for a payback of under 10 years.

As half of the funds are already committed, we urge you to act now if you want to take advantage of this generous state incentive.  Contact us to get started with a free evaluation.

Clean energy advocates in New Hampshire have two big reasons to be thankful this season – the New Hampshire Public Utilities Commission has announced an expansion of the solar hot water rebate available to homeowners and has released the application for their commercial solar hot water and solar electric rebate (PDF).

Here are some details on both programs:

Residential Solar Thermal is Hot

The solar hot water rebate in New Hampshire is tiered based on the performance of the system, which is expressed in MMBTU / year. This consists of a state rebate that ranges from $600-900 and a federal rebate which has been raised from $750 to $2,000.

Here’s what the rebate program looks like for different kinds of systems:

For a typical residential project (2 flat plate collectors which produce ~18.25MMBTU/yr) installed at a cost of around $10,500, the incentives amount to $5,750, well over half the cost of the system!

The rebates are retroactive, as well, so if you recently installed a solar hot water system and qualified for the New Hampshire state rebate, you can expect a holiday gift from the PUC soon.

Rebates Arrive for Business

The solar hot water system for Moat Mountain Brewpub will save the brewery an estimate 520 gallons of oil a year

Equally exciting is the arrival of the much anticipated commercial solar hot water and solar electric rebate.

This program makes $1,000,000 available to solar thermal and solar electric projects for businesses, schools, municipalities, apartment buildings – basically any structure not eligible under the residential program.

The rebates are pretty straightforward:

• Photovoltaic (Solar Electric): $1/Watt up to $50,000 (or 25% of the project cost, whatever is less)
• Solar Thermal rebate: $0.07 per kBTU/year up to $50,000 (or 25% of the project cost, whatever is less)

Like the residential solar hot water program, a RETScreen modeling analysis is used to calculate the kBTU/year performance of the solar hot water systems.  Solar electric is fixed based on the nominal wattage.

Solar Economics are Amazing

The generous rebate makes it extremely attractive to invest in solar if you’re a business.  Let’s take, for example, a medium scale solar thermal project for a business that uses a lot of hot water – a hotel or retirement home, perhaps – and is currently heating that water with oil.

We’ll propose a system of 20 flat plate hot water collectors and several super-insulated tanks that will produce over 182,500,000 BTUs/year of clean thermal energy.  We’ll imagine that the system will save 2,300 gallons of #2 oil per year, a result of both reduced oil use and greatly reducing standby losses of the oil boiler in the summertime.

Assuming this hot water system costs around $100,000 gross to install, the fuel savings alone will pay for the cost of the system within its first decade of operation.

However, now there is an exciting suite of rebates to apply:

$100,000 gross installed cost
($30,000) federal tax credit
($28,900) accelerated depreciation – avoided taxes over 5 years thanks to lowered net income, assumes 34% marginal tax bracket
($12,775) state rebate – $0.07/modeled kBtu/year
$28,325 net investment – less than a third of the total cost of the project!

Within this new context, that same solar hot water system will pay for itself within two years thanks to the fuel savings.

While the wasteful boiler imagined in this formula is a “best case” scenario for solar, the economics work out for businesses of all sizes who are ready to both take an enormous cut out of their carbon emissions and save money while doing it.

Efficiency Maine has announced that their popular $1,000 summer promotion for the Home Energy Savings Program (HESP) has been extended. Sign up by August 31st to qualify for an additional $1,000 beyond the existing $1,500 – $3,000 of incentives available in the program.

Here’s how it works:

• You no longer have to complete the project by August 31st.  Simply send in your application using the Efficiency Maine website.
• You’ll need to have an energy audit completed by September 30th and the project completed by December 31st.
• The $1,000 bonus is above and beyond the HESP standard rebates, which are:
  • 30% of Project Cost up to $1,500 for projects that will result in 25% – 49% total annual thermal energy savings - OR -
  • 50% of Project Cost up to $3,000 for projects that will resulting total annual thermal energy savings that will be 50% or more
• If solar hot water is part of the HESP project you’ll still get the standard solar hot water rebate, including an additional $500 for a total $1,500 solar hot water rebate.

To get started with the HESP program, be sure to submit a request before the August 31st deadline – that will secure your $1,000 bonus rebate. Then find an energy auditor – if you’d like a referral in your area just contact us!

The Home Energy Savings Program is funded by a stimulus grant from the American Recovery and Reinvestment Act (ARRA).

The Granite State has already been a solar leader in New England with their generous $6,000 cash rebate for residential solar electric systems up to 5kw as well as an average $1,500 rebate for solar hot water.

Now New Hampshire has taken the next step – mandating utilities to pay the customer for excess electric generation!

Yes, New Hampshire now requires utilities to pay customers when their solar electric system generates more electricity than they use.

The legislation, House Bill (HB) 1353 states that:

the customer-generator may elect to be paid or credited by the electric distribution utility for its excess generation at rates that are equal to the utility’s avoided costs for energy and capacity to provide default service as determined by the commission consistent with the requirements of the Public Utilities Regulatory Policy Act of 1978 (PURPA)

Emphasis Added

Wow!

How Much Will I Be Reimbursed?

In Germany, getting paid for solar electric generation is well-known, the special rate that you receive for excess solar electric generation is called a feed-in tariff.

New Hampshire’s program is a bit different, in that customers will get reimbursed closer to market rates for electricity, rather than a special “feed in” rate (which, in Germany, generates a roughly 8% return on investment for owners of solar systems).

The legislation puts it this way:

Each net energy metering tariff shall be identical, with respect to rates, rate structure, and charges, to the tariff under which a customer-generator would otherwise take default generation supply service from the distribution utility.

While the legislation is still in the process, should the full distribution cost of electricity be included in the reimbursement, that would result in a rate of close to .15c/kwh. We will post a follow-up once we better understand the details of the program!

When Can I Get Started?

The legislation is marked to be effective August 13, 2010.

In the meantime, solar electricity continues to spin your meter backwards and reduce your electric bill to zero so there’s no reason to wait!
