3 Hidden Costs of DIY Solar

Thursday, May 27th, 2010

As more and more homeowners discover the benefits of harvesting solar energy, there are growing numbers of solar electric and solar hot water kits appearing on the market.

Most of these are billed towards the adventurous homeowner – those who might think that a project that spans a couple of weekends is worth saving some money over hiring a professional.

While we very much respect the DIY attitude of solar energy enthusiasts (indeed, the whole industry has its roots in the tinkerers who have been building their own systems since the 70s), there is a lot more to consider when installing a solar energy system than the DIY system literature would have you believe.

Bottom line: it may cost you much more than you expect to do it yourself.

1 – The Real Cost of Parts and Labor

The major assumption with going the DIY route is that by eliminating professional labor rates, you’ll drastically reduce the cost of a solar energy system. After all, professionals will charge you $20+/hr, while your own labor is free, right?

Well, it’s not quite so easy.

Equipment costs account for roughly 80% of the cost of a solar energy job, and professional solar companies get considerably better prices on parts. Quite frankly, we’re shocked at some of the prices being asked for the DIY kits.

We found one solar hot water kit, for example, fetching $6,500 (prior to incentives). Compared to a professional installation with better performing parts, the difference is less than $2,000.

We find similar premium prices on solar electric modules. While we can purchase and install solar electricity for roughly $5.25/watt right now, we’ve seen solar panels advertised for $5.5/watt.

Yes, the actual parts – without wiring, inverter, mounting equipment, or labor – are being sold retail for more than the installed cost from us!

Professional labor rates are anything but price gouging – on every system we install, you benefit from the cumulative expertise of engineers from MIT, Dartmouth, and UNH, and practical experience on 2,500 systems.  Our installers in the field are professionally licensed plumbers and electricians, and we invest heavily in training so that our standards of excellence are hard to match.

You’d be hard-pressed to find a group that can install a system as efficiently and professionally as our gang!

2 – What it Takes to Get a Rebate

Something that is not usually advertised with off-the-shelf solar kits is that in order to qualify for federal and state rebates, you need a professional plumber or electrician to sign off on the installation.

Wait, what – after saving some money by doing the installation yourself, you’re still expected to have a professional on board?

While it may seem unfair, the federal government and states require a professional sign-off as a safety measure for you.

Poor performing and hacked-together systems were a real problem in the 70s and today’s requirements aim to ante up professionalism in the industry by requiring standards such as SRCC ratings on equipment and credentials (such as NABCEP) from installers.

In some states, such as New Hampshire, the rebate application requires even more paperwork and verification – including panoramic shots the southern exposure, a solar pathfinder photo, and robust parts specifications.

If the amount of labor and expertise it takes to install a solar kit doesn’t scare you off, the paperwork just might!

And without access to state rebates, the cost/benefit of DIY vs. professional solar tilts even further to the side of a professional installation.

3 – Who Do You Call in the Middle of the Night?

The fact that solar installations should last 20+ years is a big part of the equation of up-front cost vs. return on investment equation.

With a professional installation, you are guaranteed a code-compliant, rebate-ready system. At ReVision, we also back all of our systems with 24/7 service.  While nearly all our systems run trouble-free, in the rare occasion you do encounter a problem, you can rely on us to fix it promptly.

If you read the fine print with DIY solar kits, you find a remarkably different approach to service. Not only is there no emergency service to be found, but you may need a professional installation just to get the manufacturer to honor their warranty.

Yes, to repeat – we found one DIY kit that says that unless certain parts of the system are professionally installed, the system is ineligible for warranty coverage.

Contrast this with reputable manufacturers of professional-grade solar equipment, who warranty their products for 25 years (in the case of photovoltaics) or 10-20 years (in the case of most solar hot water equipment).

Even the manufacturers of the DIY systems themselves acknowledge the importance of professional installation!

Invest in the Long Term

If you’re a homeowner who has enough projects on the weekend already (or would rather just enjoy your time off!) it’s really hard to justify putting yourself through a DIY solar installation.

Professional installation will save you money in the short-term, and provide you peace of mind in the long-term – and who can put a price on that?

Solar for Weatherbee School in Hampden featured on WABI

Monday, May 24th, 2010

A little over a month ago, WABI (CBS affiliate in Bangor, Maine) featured a story on The Weatherbee School in Hampden, Maine, where a group of students dubbed the “Green Team” helped win the grant from the Earth Day Network to install a 2.3kw solar electric system on the roof of the school.

Here’s WABI’s coverage of the student green group:

Installation of the system was completed just last week, and the system has enjoyed beautiful sunshine since!

Environmentally-conscious family in Woolwich, Maine, reduces its carbon footprint by living smallThe home of ReVision Energy customer Ben Tipton and his family appeared in this May/June 2010′s Design New England, which highlighted their commitment to living small as a path to sustainability.

Here’s a sample from the story written by William Morgan with Photography by Eric Roth:

The new house in woolwich, maine, is testament to Ben Tipton and Michelle LaRoque’s belief that while they cannot change their past carbon footprint, theywill do everything they can to reduce their children’s. Having designed and built an energy-effi cient house in Hartland, Vermont, they realized they could go even smaller. Their goal was to spend less on a mortgage and more time with their children…

Gulf Oil Spill Points Out What We Already Know – It’s Time to Get Off Oil

Thursday, May 20th, 2010
Gulf Oil Spill is Spreading Towards Gulf Loop Current
Enough crude oil has spilled in the gulf to power all of Maine’s oil-based electrical generation plants

It’s now been a month since the catastrophic drilling accident that lead to the loss of 11 lives and the spewing of at least 5,000 barrels of oil into the Gulf of Mexico each day (some scientists say that number may be much higher).

We won’t spend time here elaborating on the unprecedented environmental disaster save to say that all conscientious people are taking a hard look at their lifestyle and evaluating how we can get this nasty black stuff out of our lives.

Many of us feel powerless about our reliance on oil – we need basic transportation, we need homes that are comfortable to live in, and power to do our jobs and run our households. How can we reduce the role of oil in our lives?

It’s Going Out the Window

What you may not know is that a shocking amount of oil in New England goes into heating our homes. The US Energy Information Administration says of Maine “About three-quarters of Maine’s households – the highest share in the Nation – use fuel oil for home heating.” That amounts to roughly 17 million barrels of oil used each year (Source:
http://tonto.eia.doe.gov/state/state_energy_profiles.cfm?sid=ME).

This leads to a number of problems for us. Not only is it dangerous to use a product that is environmentally destructive, but we expose ourselves to the risk of a fluctuating market.

Maine has no fossil fuel reserves and no refining capacity – the crude oil that is imported into Portland Harbor is then shipped to refineries in Quebec or Ontario, Canada (again, US Energy Information Administration). We are vulnerable not only to ecological ramifications, but also to market forces.

Our dependence on oil emerged when fossil fuel was cheap, and weatherization poorly understood and not a priority. As a result, we see time and again inefficient mechanical systems installed on homes, causing expensive oil heat to pour, literally, out the window.

What About Electricity?

Electricity has an equally scary genesis. Maine does have a mandate for minimum 30% renewable electric sources, provided mostly by hydro. Clean, solar electric, which is proven in Maine, doesn’t yet register on the radar as a major energy source:

Electrical Generation Sources in Maine

Instead, natural gas and oil, both fossil fuels, dominate our electricity consumption. The basic reality is that adoption of renewable energy is still very slow, though the need is more urgent than ever.

How You Can Change Your Relationship with Oil

Walk more, drive less. Eat local. And consider carefully how your home consumes energy.

In many houses, switching to a solar hot water system will conserve 300 gallons of oil a year, a savings of roughly 5,500 lbs of C02 emissions each year. An average home solar electric system (sized at 3kw) will save around 2,778 lbs of C02 emissions each year (mostly from coal-fired power plants).

Alpaca Farm Gets $0 Electric Bill with Grid-Tied Solar Electric System

Monday, May 17th, 2010
Santa Maria Alpacas - Madbury, New Hampshire
The PV system was installed on a sunny shed where Alpacas live. The 4.2 kw system will offset nearly four tons of C02 annually.

Cecilia Pinto Lord, proprietor of Santa Maria Alpacas, a small alpaca farm in Madbury, New Hampshire, contacted ReVision Energy’s New Hampshire office asking how she could use solar to stabilize her long term energy costs.

Lord said she thought that there was phenomenal solar gain in an open field that the Alpacas inhabit, which we confirmed after a site evaluation.

We then designed a system that would provide renewable solar electricity for the entire property – a 4.2 kilowatt grid-tied Sunpower photovoltaic system we installed right on the sunniest of the Alpaca’s sheds.

This grid-tied solar electric system has no maintenance requirements, and produces around 5,600 kWh each year, offsetting about 7,500 pounds of CO2 emission that would have otherwise been purchased from the utility.

Cecilia recently called us and said: “I got my electric bill for April the other day, and it was zero!”

Thomas College Installs Grid-Tied Solar Electric System

Wednesday, May 12th, 2010
Thomas College Solar Power - Waterville, Maine
This solar electric system will offset nearly 15,000 lbs of C02 emissions each year. Thomas College will use the system as an educational tool in the community as well as enjoying energy savings.

Last week ReVision completed installation of a new 8.28kw solar electric system on Thomas College in Waterville, Maine. The system will produce roughly 11,170 kilowatt hours of clean electricity each year, saving roughly $1,600 each year and offseting more than 14,700 lbs. of CO2 annually.

Directing the project on behalf of Thomas College was Chris Rhoda, a ReVision Energy customer who happens to have solar electric and solar hot water installed on his home! We featured his family in our blog last year.

In addition to saving money and reducing emissions, Thomas College hopes to use the system as a springboard for sharing information about renewable energy to the Kennebec Valley area, and plans to develop an interactive website. The website will include background about the project, technical information, and system output data that will be available to the public.

According to Rhoda, “It is important to demonstrate for our community our [Thomas College's] long history of environmental stewardship. This project is just the beginning as other projects are planned that will help reduce our dependence on foreign oil and provide lower cost options for our campus. For us, solar and other newer energy sources are great complements to buildings that are well insulated, lighting systems that are energy efficient, responsible heating and cooling… it is all part of a bigger picture.”

The project was made possible in part by a grant from Efficiency Maine, which awarded a $50,000 grant to the college for the grid-tied PV solar power panel installation.

More information about the system is available in Thomas College’s press release.
