What has Five times the ROI of solar in the Desert?

Here is some more info from Dsire USA on solar in New Jersey.

And here are some thoughts about going solar in New Jersey from our friends at 1Bog.org:

$5,000 – that’s how much you could be getting paid in New Jersey this year, just for having solar panels on your roof.

It may come as a surprise, but New Jersey has the best financial incentives in the country forhome solar power. The combination of high electricity rates, the federal tax credit, and solar renewable energy credits (which pay you for producing renewable energy) means a typical solar array will pay for itself in just 4 years. After that it’s free electricity and, thanks to the renewable energy credit market, a viable source of income for the next 11 years.

Even without a solar rebate, NJ beats every other state, even sunny California (where solar is immensely popular):

solar-economics-solar-payback-time-8

The two left columns show New Jersey solar payback time with and without a state rebate. No rebate = no problem.

Why is the payback time so fast? Here are the 5 reasons why New Jersey is the best place in the country to go solar:

1. Electricity in NJ is expensive

The typical cost of electricity in NJ is $0.19 / kWh, compared to the US average of $0.11 / kWh. That means that the average electricity bill in New Jersey is around $190-$228 per month. An average-sized solar array will cover most of this, knocking about $175 / month off of that bill.

2. The Federal Solar Tax Credit puts 30% back in your pocket*

The Federal solar tax credit is a tax credit for 30% of the total system cost. While you’ll have to shell out the money up front, at the end of the year you will get a tax credit of $11,000 for a $35,000 system (assuming you have tax liability for that year–otherwise it will rollover into another next tax year). Confusing? Yes. But don’t worry – your solar installer can help you with the right forms, and you can always consult your accountant.

3. SRECs turn your roof into an ATM*

Solar Renewable Energy Credits (SRECS) are credits you get for producing renewable energy. A home accrues 1 credit for every 1,000 kWh of solar energy produced, and each credit is currently worth around $650. We’ve estimated that the average home will produce about$5,000 worth of SRECs on average per year. A new solar energy system is eligible to produce SRECs for 15 years, meaning that an average roof could earn over $75,000 by selling credits over that time period.

4. You’re getting a 15-30% discount on panels and installation with group discounts

Although we can’t disclose our south New Jersey 1BOG rate for solar just yet**, we can tell you the price for our last New Jersey solar campaign: $5.54 / DC watt. If you went to a local big box store for solar today you would see prices around $8 per DC watt–or $17,958 more for an average sized system. Our group discount is typically around 15% off competitive market rates, although in New Jersey we anticipate it will be considerably more than that.

5. If you don’t want to purchase, you can go solar for $0 down.

Our local installation partner offers PPA-financing through SunRun, which means that you can install a system for $0 out of pocket.

Even though it’s our job to bring you good deals, we’re blown away by how good solar in New Jersey looks right now. There’s no better time to make the investment, especially since you can start generating SRECs as soon as the system is installed.

* We are not tax professionals, so please make sure to consult your accountant on the tax implications of a solar installation. Additionally, please be aware that these calculations are based on several assumptions, including the future cost of electricity and value of SRECs. Yearly SREC payments have been updated in this post based on the most up-to-date information we have.

Solar Data Monitoring in California

The California Solar Initiative (CSI) is an organization that offers a cash back incentive for putting a solar system on your home or business in California.  There are two different rebate programs, Expected Performance Based Buydown (EPBB), and Performance Based Incentive (PBI). The rebate values vary according to system size, customer class, and performance and installation factors, as shown on the chart below:

CSI Rebate Graph

Here is the EPBB rebate explained by the CSI website:

Owners of solar systems less than 50 kilowatt (kW*) may apply for an up-front cash rebate known as the Expected Performance Based Buydown (EPBB)**. Program Administrators calculate a customer’s rebate using the expected performance of the owner’s system based on equipment ratings and installation factors such as geographic location, tilt, orientation and shading. Customers receive their incentive payment in a lump sum after their system in fully installed and interconnected.

And here is the PBI:

Customers with solar systems between 50 kW* and 1 MW must* apply for the Performance Based Incentive (PBI) structure. PBI incentives are a five-year stream of fixed monthly payments determined by the actual output of the system, as metered and reported to the utility. After January 1, 2010, all systems greater than 30 kW must choose the Performance Based Incentive structure. The PBI incentive path is available at any time to ANY size system.

The table below shows the effect of prices as these step declines occur, with current prices in the three territories highlighted in yellow. Residential and commercial incentives are the same price in each step; however, local governments and other tax-exempt organizations receive a slightly higher incentive because cannot qualify for Federal Investment Tax Credits on their solar systems.

The table below shows the rebate levels available at various steps, and information on currently applicable step in your region is available at the California Solar Initiative Trigger Tracker.

However, there is a catch. In order to use this great incentive, the homeowner or business must “record the output of the PV generator”, and “pay for 5 years of data communication and performance monitoring and reporting services” (emphasis mine). So who are these Performance Monitoring and Reporting Services? After some major digging through the beaurocratic labyrinth of CSI and Pacific Gas and Electric’s websites, I found this list:

  1. Applied Power Technologies, Inc.
  2. Deck Monitoring, LLC
  3. Draker Laboratories, Inc.
  4. Energy Recommerce, Inc.
  5. Enflex
  6. Enphase Energy
  7. Fat Spaniel Technologies
  8. Locus Energy
  9. NergyOS, Inc.
  10. Recurrent Energy
  11. SatCon Power Systems
  12. SolarCity
  13. Thompson Technologies, Inc.
  14. Trimark Associates, Inc.

So there you are! The list of the 14 privileged Performance Monitoring and Reporting Service providers. These chosen few capitalize on every solar installation in the state of California.

Sandia National Laboratories scientists have developed tiny glitter-sized photovoltaic cells that could revolutionize the way solar energy is collected and used.

The tiny cells could turn a person into a walking solar battery charger if they were fastened to flexible substrates molded around unusual shapes, such as clothing.

The solar particles, fabricated of crystalline silicon, hold the potential for a variety of new applications. They are expected eventually to be Read More… »

Solar data monitoring and the TED

Recently I came across a new Google service, the Google Power Meter. This is a Google.org service that provides users with the ability to monitor their house’s energy usage from any web browser. It comes packaged in a very nice user interface, with interactive graphs and statistics in real time.
I found that Google Power Meter harvests energy data through its partners, one of which is The Energy Detective, a small company that manufactures a device that harvests the data. The neat thing about the TED, as The Energy Detective’s device is called, works not only for monitoring your home’s energy use, but also your solar systems production!
I will be posting more on Solar Data Monitoring later on, but for now, check out both of these websites, and evaluate whether or not The Energy Detective might be right for your solar system.


Should you spring clean your solar panels? – Google

From the Official Google Blog:

Ever since we assembled a 1.6 MW solar panel installation at our headquarters in Mountain View in 2007, we’ve been wondering, “Does cleaning the solar panels make them more effective?” We thought it might, but we needed to be sure. So we analyzed the mountains of data that we collect about the energy that these panels produce — after rain, after cleaning and at different times of the year.

We have two different sets of solar panels on our campus — completely flat ones installed on carports, and rooftop ones that are tilted.

Since the carport solar panels have no tilt, rain doesn’t do a good job of rinsing off the dirt they collect. (Also, our carports are situated across from a sand field, which doesn’t help the situation.) We cleaned these panels for the first time after they had been in operation for 15 months, and their energy output doubled overnight. When we cleaned them again eight months later, their output instantly increased by 36 percent. In fact, we found that cleaning these panels is the #1 way to maximize the energy they produce. As a result, we’ve added the carport solar panels to our spring cleaning checklist.

The rooftop solar panels are a different story. Our data indicates that rain does a sufficient job of cleaning the tilted solar panels. Some dirt does accumulate in the corners, but the resulting reduction in energy output is fairly small — and cleaning tilted panels does not significantly increase their energy production. So for now, we’ll let Mother Nature take care of cleaning our rooftop panels.

We’ve also been crunching numbers on dollars-and-cents; the more energy our panels produce, the sooner we’ll be paid back by our solar investment. Our analysis now predicts that Google’s system will pay for itself in about six and a half years, which is even better than we initially expected.

If you want to learn more about our solar study, check out these slides showing the effects that seasonality, tilt, dirt, particulate matter, rain and cleaning have on Google’s solar energy output. We hope you solar panel owners out there can tailor our analysis to the specifics of your own installation to produce some extra energy of your own!
